Tianjin Petrochemical's "Small Ethylene" makes up for shortcomings and ranks in the forefront

"Small-scale, old-fashioned, mid-to-late", how to achieve economical operation? The person in charge of Tianjin Petrochemical Olefin Department said frankly, "Stable operation is the foundation, excellent indicators are the guarantee, and economic benefits are the go.

They continue to strengthen the control of key units, continue to optimize the structure of raw materials, tap the potential of the device on the basis of the smooth operation of the device, and pursue maximum benefits with new products with high added val.

Smooth operation is the "root" to break through the bottleneck with careful care

"The tower pressure of the debutanizer can be controlled at 410KPa, which is within the normal ran.

As the device enters the end of the four-year repair operation, various hidden dangers increase, and the high temperature in summer is coming, and the stable operation of the device under high load is facing challeng.

They also compared the alarm data to find potential problems of the device and formulate targeted measures to solve th.

In order to make the device "eat and eat well", they focus on optimizing the structure of raw materials, carefully adjust the "recipe", rationally allocate the proportion of light and heavy raw materials, increase the proportion of naphtha from 15% to 28%, and the proportion of light napht.

Economic and technical indicators are "dry", optimizing operation and precision tackling

Outside the ethylene workshop that was inspecting, Xiao Yan opened the furnace door, and a wave of heat hit his face, but he didn't feel the sultry weath.

With the premise of stable operation of the device, the olefins department aimed at high load and optimized indicators to carry out research, especially the key equipment cracking furnace as the main targ.

The ethylene workshop also organized a small index competition with the goal of improving the thermal efficiency of the cracking furnace, and encouraged employees to keep an eye on the operating parameters of the cracking furnace, and strictly control the process parameters such as the exhaust gas temperature of the cracking furnace and the outlet temperature of the waste heat boiler, so as to stabilize the cracking raw materia.

The high attached yield of ethylene is also one of the important technical and economic indicators of the ethylene pla.

From January to May, in the special competition for the operation of 14 sets of ethylene plants in the headquarters, "small ethylene" ranked first, and the stability rate and processing loss rate were both the be.

Economic benefits are the "fruit" to expand the profit space and strive for excellence

"The pursuit of maximum benefit is the foundation of an enterpri.

Under the premise of high-load and stable production of ethylene units, the olefins department continuously optimizes various product indicators, delivers high-quality and sufficient raw materials to downstream units, and creates favorable conditions for the development and production of high-value-added products for polyethylene and polypropylene uni.

They aimed at the high-end market, and continued to carry out technological innovation in combination with the devi.

While realizing "one generation of production, one generation of research and development, and one generation of reserve", they turned the disadvantage of "small scale and high cost" into the advantage of "small ship and easy to turn around", keeping an eye on the market vane to ensure that the device is always switched in the best state Brands, stable and high-yield, increase the production of high value-added products, reduce the generation of transition materials, and keep various economic and technical indicators stable and improvi.

From January to June, 74,700 tons of new polyethylene and polypropylene products and special materials were produced, accounting for 778% of the total polyolef.
