  • The environmental protection industry will be further integrated, and technological advantages will be crucial.

    In recent years, with the release of pollution control demand, the development of China's environmental protection industry has been accelerated, and the number of enterprises has increased dramatically. As the industry competition intensifies, the importance of technology is further highlighted, and the industrial consolidation trends have emerged.
     
    According to the Development Report of China Environmental Protection Industry (2018) issued by China Association of Environmental Protection Industry (CAEPI), the total operating income of China's environmental protection industry is expected to exceed CNY two trillion in 2020. The growth rate of the environmental protection industry is much higher than that of the national economy.


     
    At the 20th China IE expo held in April 2019, there were 2,047 exhibitors, an increase of 17% over 2018. Jiang Gang, General Manager of China Trade Munich Exhibition (Shanghai) Co., Ltd., introduced that according to the exhibition situation, atmospheric management, water environment management and soil remediation are the three major sectors for environmental pollution prevention and control, the number of related enterprises is the overwhelming, and environmental monitoring enterprises obviously increase. As garbage classification and resource recycling become hot topics, the number of relevant companies is also growing.
     
    Companies with technological advantages will be superior in the industrial consolidation. "In the long run, SMEs are still at a disadvantage in winning orders. In the past two years, our company's orders have grown rapidly. The reason is that our products have many patents and have unsubstitutability in some degree." Cai Yongping said, Director of Beijing Zhongke Bolian Environment Engineering Co., Ltd.

  • The function of tailings dry discharge in sludge treatment process

    The first stage is sludge concentration to preliminarily reduce the volume of sludge;
     
    The second stage is sludge digestion to decompose the organic matter in the sludge;
     
    The third stage is sludge dewatering to further reduce the volume of sludge;
     
    The fourth stage is sludge disposal to treat the final sludge by some means.
     
    The above typical sludge treatment process can achieve the reduction, stabilization, harmlessness and recycling of sludge after treatment.


     
    (1) Reduction: Because the sludge has high water content with large volume and fluidity. After the above process, the sludge volume is reduced to one-tenth of its original volume, and its state is converted from liquid into solid, which is convenient for transportation and consumption.
     
    (2) Stabilization: The content of organic matter in the sludge is very high, which is highly prone to decomposition and produces foul odor. After the digestion of the above process, some of the easily spoiled organic matters are decomposed and transformed, and the malodor is greatly reduced, which is convenient for transportation and disposal.


     
    (3) Harmlessness: The sludge, especially the primary sludge, contains a large number of pathogenic bacteria, parasitic eggs and viruses, which are easy to cause widespread spread of infectious diseases. Through the digestion stage in the above process, most of the eggs, pathogens and viruses can be killed, and the hygienic indicators of the sludge are greatly improved.
     
    (4) Recycling: Sludge is a resource that contains a lot of heat, and its calorific value is between 10,000 and 15,000 kJ/kg (dried sludge), higher than coal and coke. In addition, the sludge is also rich in NPK, which is an organic fertilizer with high fertilizer efficiency. Through the digestion stage in the above process, the organic matter can be converted into biogas, and the heat can be utilized, and the fertilizer efficiency can be further enhanced.

  • Influences of Solids Control System Performance on Well Drilling

    The solids control system is one of the most important parts in the well drilling, known as the filter of drilling "blood". A reasonable solids control system can effectively control the solid-phase content in the drilling fluid, reduce the complexity of the drilling process and the probability of accidents, and serve as a significant technical means to achieve safe, efficient and economical drilling.


     
    The solids control system is composed of drilling fluid shale shaker, desander, desilter, centrifuge, centrifugal pump, vacuum degasser, mud tank and other equipment. The safe and stable operation of the solids control system affects the accident risk during the drilling process. Therefore, the performance evaluation and optimization of the solids control system have crucial practical significance for drilling projects.


     
    According to the characteristics of stratum cuttings particles and the properties of drilling fluid, it can reduce the risk of accidents during drilling operations and increase the rate of penetration of safe drilling to reasonably choose solids control equipment that meets the drilling requirements.

  • Application of solidification and stabilization technology for waste drilling cuttings

    Nowadays, the exploitation of resources is constantly improving. To achieve better results in the processing and development of important resources, it is necessary to strengthen the effective treatment of waste drilling cuttings. The application of solidification and stabilization technology meets the numerous requirements of waste drilling cuttings, will not cause serious damage to the environment, will not affect local development stability, has high technical reliability and feasibility, and meets the future disposal standard of waste drilling cuttings. Therefore, a perfect solution must be set in the application process of this technology.


     
    In the application process of the solidification and stabilization technology, it can basically be completed in combination with the demand for waste drilling cuttings, and can achieve good results in many tasks. In the future, we should continue to increase the adjustment of this technology. For example, on the one hand, the technical operation of waste drilling cuttings in different places must be done in accordance with local restrictive conditions, especially in the response and resolution of special situations, to continuously reduce the deficiencies of traditional work and strengthen the reliability of and improve the feasibility of this technology. On the other hand, the strategy of technical adjustment should maintain sufficient perfection to promote the effect of the technology to be enhanced better.

  • China’s shale gas is being exploited at a large scale.

    The advent of the low oil price era has brought challenges to global oil and gas development. Despite the challenges, China's shale gas industry is still booming and making great progress. The industry predicts that during the “13th Five-Year Plan” period, China will substantially increase shale gas production through technological breakthroughs, policy support and market competition, and build shale gas into an important part of natural gas supply.
     
    Recently, the website of the Ministry of Science and Technology reported that the cumulative gas supply of the first large shale gas field in China, Chongqing Fuling Shale Gas Field, exceeded 10 billion cubic meters. Since September 10, 2012 when the Ministry of Land and Resources released the first round of shale gas exploration rights bidding announcement, China's shale gas industry production has shown scale over nearly five years.


     
    Nowadays, along with the interconnection of the Wangchang Gas Pipeline from Fuling to Chongqing Shizhu County and the Sichuan to East Gas Transmission Pipeline, the Sichuan shale gas benefits the Yangtze River Economic Belt. A large number of petrochemical enterprises, represented by Sinopec Sichuan Vinylon Works, have formed a shale gas processing and production service chain.
     
    It is believed that China will usher in the prosperity of comprehensive development, flexible innovation and global cooperation in the field of shale gas in the next few years. China's dependence on clean energy will be greatly improved in the future, achieving an all-round balanced development of the environment and economy.

  • Another shale oil and gas field in China is about to be “awakened up”!

    China is a country with vast resources, where there must be more oil reserves than many other countries. However, there are more population and more consumption in China, which is directly proportional. For how to solve this problem, we have to mention the shale oil and gas fields in Xinjiang. It is reported that China has decided to exploit the Jimsar Oilfield. This huge oilfield was discovered by scientists a long time ago, but it has been idle. Unless there is no other way, China still hopes not to disturb the Jimsar Oilfield so as to leave a path for the future. However, as far as its current development trend, China has decided to awaken the Jimsar Oilfield!


     
    In the year of 2019 that has already arrived, China will usher in one billion tons of oil resources. This is definitely a year of shale revolution. In addition to the Jimsar Oilfield, Xinjiang has many other precious shale oil and gas fields because of its large area. But, if the oil exploitation is too much, it may take only a short time for billions of tons of oil to disappear from the earth.

  • Environmental protection equipment manufacturing still has a long way to go.

    At present, strengthening the environmental protection equipment manufacturing industry, developing advanced environmental protection equipment, and expanding the scale of the environmental protection equipment manufacturing industry are the main lines of current environmental protection industry development. Environmental protection equipment manufacturing not only helps environmental governance to better cope with market changes, but also helps environmental protection enterprises to better cope with continuous comprehensive services, meet the refinement requirements under the new normal, and improve the benefits of environmental governance. However, although environmental protection equipment manufacturing has developed rapidly in recent years, it still has a long way to go.


     
    We must continue to make breakthroughs in the core component technology of environmental protection equipment manufacturing. The industry believes that the key to environmental protection equipment manufacturing is the basic technology, which is the design and manufacturing of core components. From the perspective of the development of industry trends, the two major fields, including market share and industrial agglomeration, have been placed at a crucial position in the planning of environmental protection equipment manufacturing in China. As one of the important contents of the development of environmental protection equipment manufacturing, the future technological innovation will also transform the industry.
     
    Under this situation, the transformation and upgrading of environmental protection equipment manufacturing enterprises still needs to accelerate the pace, constantly update technology, adjust strategies, and grasp market trends. The internal equipment manufacturing technology and the external environmental governance model need to be continuously integrated. The integration of these two technologies represents the direction of environmental equipment manufacturing development. Specifically, equipment manufacturing is the foundation, and environmental governance means the interconnection of everything, so that enterprises can deeply understand the needs and directions of users.

  • Piling mud treatment equipment with large capacity

    The piling mud at a construction site has a large amount, and once the construction machinery runs, a large amount of mud can be produced in a short time. Due to no large volume of mud pit on the site, direct discharge will pollute the environment, and the truck transportation cost is very high, so the treatment on the spot is the best solution. The piling mud treatment equipment is required to have a large single-machine processing capacity and a “stomach” big enough to “digest” the mud in time.
     
    Improper treatment of piling mud can pollute the environment, cause a lot of water and soil loss, silt up rivers, affect water quality, and damage municipal facilities. The methods for early-stage treatment of mud are landfill, natural drying, etc. These relatively primitive methods are costly and inefficient, far from meeting the growing demand for mud treatment, and the mud has become a problem that plagues the normal construction of the project. Therefore, in recent years, KOSUN has introduced a new process of concentration, dosing, screw extrusion and gravity separation on the basis of mud dewatering and drying treatment.


     
    KOSUN specializes in the production of automated mud treatment equipment, which is suitable for all kinds of piling mud. Whether it is more sand in the mud or more clay, the piling mud dewatering machine can be applied. Generally, the amount of mud generated during the piling process is relatively large. This piling mud dewatering machine can just meet such a large amount of sewage. The large-capacity piling mud treatment equipment can continuously run for 24 hours each day, which can separate mud while being fed, and the separation is fast and efficient. The running cost of the equipment is relatively low, which can save a lot of operating costs for the piling project. Through the treatment equipment, the mud becomes filter cake, which lowers the difficulty in transportation and reduces the transportation volume.

  • Solvent extraction method for oil sludge treatment

    Solvent extraction is an effective technique for treating oily sludge with multiple sediments, small particles and oil content of 10%-20%. The process utilizes an extractant to dissolve the oily sludge. After being stirred and centrifuged, most of the organic matter and oil are extracted from the mud by the extractant; then the extract is recovered for distillation, the solvent is separated from the mixture for recycling, and the oil is used for refining.
     
    Solvent extraction is generally carried out at room temperature. The larger the solvent ratio, the better the extraction effect, but when the solvent ratio is large, the extraction equipment will have a larger load and a relatively larger energy consumption. After the extracted oily sludge is distilled, the heavy oil in the oily sludge can be effectively removed, and the oil removal rate can reach above 90%. Due to the high cost, the extraction method has not been applied to oily sludge treatment in refineries, and an extractant of a high performance-price ratio has become the key to the development of this technology.


     
    The process experiment uses chloroform solvent to extract and steam to distill oily sludge. The dewatered oily sludge is naturally dried, from which sundries are removed, and then is pulverized. The sludge is dissolved with chloroform, and then use steam to distill and deoil at 320-480°C under a pressure of 0.2MPa. The experimental results show that when the oily sludge is extracted by adding 3 times of extraction solvent, and then is distilled for 45min as per the ratio of 1g oily sludge to 0.5ml water at 400°C, the deoiling rate is up to 80-90%.

  • Sludge disposal industry breaking into countdown

    From the additions of sewage treatment → no need of treatment, direct landfilling to the concomitant of sewage treatment → needing harmless and resource disposal, the secondary pollution of sludge gradually attracts the attention of the environmental protection industry. Moreover, due to the large amount of stock, the market for the sludge treatment has been rising in recent years.
     
    Although there are also many voices pointing out that the “deficiency fire” in the sludge treatment market is too vigorous, it cannot be denied that the background of policy support is favorable to industrial development, and we must also carefully review the technological changes that bring a noticeable driving force in accelerating the sludge treatment industry on track.


     
    At present, the technical process for sludge disposal is spreading everywhere, and it is especially important for how to improve the disposal efficiency as much as possible, and meet the disposal needs under the requirements of harmlessness and resource utilization.
     
    With the upgrading of the sewage treatment plant, the following methods have been derived from sludge disposal: coupled waste incineration, co-treatment of cement kiln, and participation in soil remediation. The technical process has broken through the bottleneck, and the market scale is already on the eve of the outburst.
     
    The conversion from "deficiency fire" to practical countermeasures represents the general trend. The speedy entry of capital will bring more challenges. How to seize the opportunity and preemptively occupy the highland still needs technology-oriented enterprises to make a forward-looking layout.
