Yangzi Petrochemical PTA steam turbine single test success

On the evening of September 29, Yangzi Petrochemical's expansion of the 450,000 tons/year PTA production line steam turbine was successfully tested.

The air compressor unit of the company's expansion of 450,000 tons/year PTA production line consists of steam turbine, air compressor, exhaust gas turbine and motor/generator four main engines and auxiliary equipment, piping, oil circuit system and control system. Designed by Sinopec Engineering Company, manufactured by Mitsubishi Corporation of Japan, and installed by Sinopec Corp. The successful single-test of the steam turbine created conditions for the air compressor unit to test the vehicle, and laid a solid foundation for the expansion of the 450,000-ton/year PTA production line.

In order to achieve a successful single test of the steam turbine, the chemical plant organized various professional departments to do a lot of careful preparation work, overcome difficulties, continuous operations, high-standard pipe flushing and flushing; oil system oil washing; instrument adjustment The inspection and confirmation of the school and the interlocking circuit were actively coordinated with the experts of Mitsubishi Corporation of Japan to deal with the problems found in the preliminary inspection and commissioning. The company's leaders attach great importance to and care about the single test of air compressor units and steam turbines, and repeatedly went to the site to inspect and guide the work, which effectively guaranteed the success of the steam turbine test.

After the successful steam turbine test, the chemical plant will continue to cooperate with the manufacturer's experts to solve the problems in the oil system, and prepare the three-machine joint test of the air compressor unit and the joint test of the four-machine test to ensure the successful joint test of the air compressor unit. , attacked the key control points for the expansion of the 450,000 tons/year PTA production line.

Table mat features
The main table mat is made of antistatic material and dissipative static material, such as rubber. The surface layer is about 0.5mm thick dissipative electrostatic layer, the bottom layer is about 1.5mm thick conductive layer. Commonly used for 2mm double layer composite structure. Table mat use time lasting, has good acidproof, anti alkali, anti chemical flux properties, and wear resistance, easy cleaning. Conductive mat is made of high quality conductive materials, synthetic rubber.
The material and the characteristics of the crystal table mat. Come and learn about: first we know oh, soft glass, also known as the crystal plate: is a new generation of high-tech products, it replaces the traditional glass heavy fragile, wounding disadvantage outside it has a lot of advantages.
It is suitable for the dining table, desk, desk, bedside table and all the table. The high degree of transparency, and can heat the soup, tea, cold resistance, weight, non-toxic and tasteless, green environmental protection.
After scientific design, the use of imported PVC new health and environmental protection materials.
The characteristics of high resilience and high resistance to compression and compression can be suitable for a variety of environments.
It has the characteristics of non toxic, soft and transparent, safe insulation, easy cleaning and so on.
The overall heat deformation, high temperature resistance, chemical stability, non stick paint, aging is not easy.
Crystal board can be quite furniture long service life; effectively prevent burns, cuts, scratches and other external damage, make your furniture gets more effective protection.
A glass plate is pressed on a lot of desk, which is convenient for writing. Now, a new type of material is soft glass instead of glass become the people's favorite. At work, it is widely used in electronics, chemistry, pharmacy, food factory, garment factory, working platform, the surface of a variety of office machines, etc.. Family life, it is widely appeared in the glass surface, can not only reflect the true nature of the glass, fashion, and can prevent the glass furniture surface scratch.
