1. Project background introduction
The Sichuan-east gas transmission project of Sinopec pipeline is another landmark event in the construction process of natural gas pipeline network in China after the west-to-east gas transmission project. When completed, the pipeline will become a veritable trans-regional green energy channel in eight provinces and cities, including Sichuan and Chongqing in western China, Hubei, Jiangxi and Anhui in the central region, and Jiangsu, Zhejiang and Shanghai in the eastern ministerial triangle.
According to the plan, the construction of the Sichuan-east gas transmission project mainly includes three parts: first, the production capacity construction project of the gas field, in which 81 development wells will be deployed, supporting the construction of surface gathering and transportation and public works, and it is estimated that the production capacity of 12 billion cubic meters of purified gas will be completed by the end of 2010. The second is the natural gas purification plant project, which is mainly aimed at the purification treatment of high contents of hydrogen sulfide, carbon dioxide and natural gas in Puguang gas field, with an annual output of 12 billion cubic meters of purified natural gas and 2.83 million tons of sulfur after completion, and will become one of the largest natural gas purification plants in the world; third, the Sichuan-to-east natural gas pipeline project, with a total length of 2390 km, of which the trunk pipeline runs from Puguang, Sichuan in the west to Shanghai in the east, with a total length of 1700 km.
According to the plan approved by the state, the gas volume of the Sichuan-east gas transmission project is distributed as follows: under the premise of reasonable supply of gas used in Sichuan and Chongqing, the main suppliers are Jiangsu, Zhejiang and Shanghai, taking into account Hubei, Anhui and Jiangxi provinces along the route. The project takes Puguang gas field as the main gas supply source, and the peripheral structure of the gas field and Tongnanba gas field as the upper production and replacement resources.
2. Project objectives and principles
As the largest natural gas investment project of Sinopec, there are many risks and challenges in Sichuan-to-east gas transmission. In the complex natural and social environment, such a large-scale project is bound to encounter many severe challenges, and its implementation process is bound to be full of risk interference and threats from various aspects. the problems that need to be solved, in addition to the problems of the general long-distance pipeline, its unique practical problems must also be considered according to the actual situation of the target market of "Sichuan-to-east gas transmission". As one of the suppliers in such a large project, it is a common goal to ensure the smooth construction of the project.
3. Detailed introduction of project implementation and application.
Sichuan-East Gas Transmission carried out bidding for compressor units of Golden Compressor Station, Yichang Compressor Station and Wuhan Compressor Station in May 2015, with a total of 9 sets. 9 sets of control systems and 21 sets of control systems are all Beijing Kangjisen Tricon Ts3000 control systems.
When we use compressors to transport gas and increase gas pressure, compressors must be driven by power equipment, which can be motor, steam turbine or gas turbine. In addition, compressor units need auxiliary equipment systems, such as interstage cooler, interstage separator, lubricating oil station, regulating oil station, compressor sealing system (dry gas seal, oil seal, steam seal), gearbox, turning device, etc. In order to ensure the long-term and stable operation of the compressor unit and the coordination among all the equipment, we can ensure it only by means of control. Take the compressor driven by steam turbine as an example, the control of the turbine compressor unit includes the following contents: start-up and stop control of the compressor unit. Compressor process monitoring; compressor anti-surge control; compressor speed control; compressor performance control; overspeed protection of steam turbine; steam turbine extraction control; compressor, turbine shaft vibration, shaft displacement monitoring; compressor, steam turbine bearing temperature monitoring; oil circuit system control; sealing system control; compressor, steam turbine interlock protection.
With the development of electronic technology, the control of compressor, steam turbine and auxiliary system has changed from the original single-loop control or decentralized instrument unit control mode to an integrated control system to realize the integrated control of the unit, and this control technology has become more and more mature and accepted by the majority of users. It provides many convenient factors, such as reducing installation and maintenance costs. The coordinated control between multiple loops becomes extremely easy, which improves the efficiency of unit operation, reduces the number of wrong stops and parking time, and increases the output of enterprises or chemical plants.
The company's anti-surge control technology is based on the five parameters of the compressor: inlet flow, inlet pressure, outlet pressure, inlet temperature and outlet temperature, through the calculation of unique surge control technology, output a value to realize the control of the anti-surge valve.
TS3000 anti-surge control function is an ideal means of executive surge protection, because it can respond quickly and fully meet the requirements of complex operations; at the same time, TS3000 can also perform the function of turbine speed control, and the coupling control method of surge and speed in the same system can ensure the fast response and safety of control.
4. Benefit analysis.
Compressor (unit) is the main moving equipment in petrochemical and coal chemical production units, and it is an important link in the construction of chemical plants. Large and medium-sized compressor devices need to be equipped with a special control system to effectively control and monitor the operation of the compressor. The unit control system of Beijing Kangjisen Automation Company is the special control system for controlling the compressor of petrochemical plant.
At present, the construction of domestic petrochemical production plant is at its peak, and there is a huge new investment in domestic petrochemical production every year. The demand for the control system of large and medium-sized units produced by new or modified petrochemical units can reach about 200 sets.
With the advanced products of this project, high market share and rich engineering experience, Beijing Kangjisen Automation Company completely monopolizes the market share of turbine compressor control system of more than 5 million tons / year large oil refining units, that is, it has 100% market share. It has a market share of 72% in the control system of petrochemical units. In particular, the market share of new projects started by major domestic petrochemical and coal chemical production enterprises, such as Sinopec, PetroChina and Shenhua Group, has reached 60%. The company has occupied a leading position in the unit control system market for a long time, and is in a dominant position in the market competition with advanced technical level and high-quality engineering service ability.
In recent years, large-scale petrochemical construction projects in China, national key construction projects include Fujian Refining and Chemical Integration Project, PetroChina Dushanzi Refining Ethylene Project, CNOOC Huizhou Refining Project, Zhongsha Tianjin Ethylene Project, Sinopec Zhenhai Ethylene Project, Shenhua Group Ning Coal Project, Sinopec Sichuan Petrochemical Project, Sinopec Wuhan Ethylene Project and other projects, the main unit control systems have selected the results of this project products. Fully withdraw the user and market approval of the Kangjisen unit control system.
At present, the results of this project are mainly applied to the control of turbine compressors in domestic petrochemical, chemical fertilizer, chemical and other plants.
