Qilu chlor-alkali plant vinyl chloride plant optimization production efficiency

The Chloroethylene Plant of Qilu Chlor-alkali Plant strives to optimize the production process. By optimizing equipment process problems, optimizing material allocation, and optimizing the control of water and electrical resources, the long-period economical operation of the plant and the supply of vinyl chloride monomer are promoted, ensuring downstream polymerization. Vinyl chloride devices seize market opportunities to increase production, increase production, and create more profits.

The vinyl chloride plant is linked to the process flow of the chlor-alkali plant and consumes upstream chlorine and ethylene to provide monomers for the downstream plant. The optimization of production and the long-term operation of the plant have a great influence on the entire plant. Since the beginning of this year, the workshop has adhered to stringent management principles, and has been working hard to achieve the goal of saving the work and the work of the factory. In the case of more end-of-the-box installations, the workshop has consistently optimized articles and received good results.

Not only does the elimination of parking need to be optimized, but in the production organization of the plant, the workshop also seeks to optimize the board and optimize chess. The workshop took full advantage of the low energy consumption of the new plant. Under the premise of guaranteeing the output and energy consumption of the old plant, the overall consumption of the plant was reduced by increasing the load of the new plant; the advantages of high purity of the new plant product were utilized, and efforts were made to increase the load of 120 units. Increase production of vinyl chloride monomer. The workshop also continuously reduces the load on the water coolers of new installations and insists on regular cleaning of the air cooler fins to reduce the temperature of chilled water as much as possible to reduce the entrainment of useful components of each exhaust gas and reduce the temperature of 120 units of circulating air. Increase the load, improve product purity and reduce consumption. In the first half of this year, the workshop optimized the production and completed the production of vinyl chloride monomer. The material consumption and energy consumption of the equipment also fell to varying degrees.

Optimizing the allocation of materials and water and electrical resources is a wonderful product for the optimal production of vinyl chloride plants. In the optimization of materials, the workshop focused on reducing costs and increasing efficiency, and strived to find alternative energy sources. The device cracker has been using the more expensive carbon 4 as fuel. Since last year, the workshop has tried to use cheap coking dry gas as an alternative energy source and succeeded in new installations. This year, the workshop has increased its efforts to tackle the problems of continuous use of coking dry gas in old cracking furnaces. At the end of March, it succeeded in renovating the fire nozzles of the old equipment. It is estimated that all old equipment will be burned to dry gas. At the end of the year, production costs can be reduced by more than 8 million yuan. Since medium-pressure steam has a price advantage over high-pressure steam, the workshop has deactivated high-pressure steam of 4.0 MPa in the old equipment and switched to 1.5 MPa of medium-pressure steam. At the same time, as far as production permits, turbine steam is also used as much as possible. Reduced the cost of burning. The workshop also optimized the process route and used the opportunity of scorching to convert the new unit pyrolysis furnace feed preheater from parallel to series operation, which not only saves steam, but also helps increase the furnace load. In order to save electricity, the workshop and the electric workshop have transformed the frequency conversion of some of the motors. Now the new installation of the incinerator fan has been completed and the power-saving effect is obvious. The workshop optimized the plan at the same time, and the partial pumps of the old device and the new device were disabled at the right time to save electricity as much as possible. With regard to water-saving and emission reduction, and optimization of water resources allocation, the workshop has reformed the eyewash system and optimized the valve settings so that the eyewash system can be used without antifreeze emissions. The workshop also recycles scattered steam and hydrophobic condensate originally designed into the fouling plant through the recovery pipeline; the waste water from the top of the old plant wastewater stripper is used instead of condensate for the 200 unit system and the 600 unit pump flushing system. , And cited some of the stripped after the outgoing wastewater to the pump GA307, 130P006, 110P002 and other places often need water to flush, in order to reduce the amount of fresh water; the three oxychlorination units boiler cooling drainage system to improve the circulating water system. Through the above measures, this year's discharge of vinyl chloride plant wastewater has dropped from 25 tons per hour last year to the current 20 tons per hour, and has achieved good economic and social benefits.
