Yangzi Petrochemical seized the market opportunity to increase ethylene production. In the third quarter, the company's ethylene production, ton of ethylene raw material cost, and the yield of single-month ethylene high value-added products reached the best level in history.
The latest production statistics show that in the third quarter, Yangzi Petrochemical's ethylene output reached 210,000 tons, an increase of nearly 10,000 tons compared with the historical best level in the same period of 2016; the cost of ethylene raw materials decreased by more than 40 yuan compared with the same period of 2017; The yield of the product is up to 61.73%, and the loss rate of ethylene processing is reduced to 0.08%, which is a new historical level.
Increasing ethylene production is one of the main objectives of Yangzi Petrochemical this year. In the third quarter, the company made every effort to optimize the structure and quality of ethylene cracking raw materials, and used high-quality cracking raw materials. At the same time, timely adjust the cracking depth and steam to hydrocarbon ratio, and do a good job of ethylene. The operation mode of the combined plant cracking furnace is optimized and adjusted, and multiple measures are taken to ensure the high load and stable operation of the ethylene combined unit. The average daily output of ethylene is 2,287 tons.
Yangzi Petrochemical is also working hard to reduce the cost of raw materials per ton of ethylene. With the highest yield of ethylene high value-added products, the lowest cost per ton of ethylene raw materials, and the largest marginal benefit, the company has carried out fine calculations and optimized the production of ethylene raw materials. Results.
The high value-added product yield of ethylene is one of the key technical and economic indicators for measuring the operational performance of ethylene plants. Yangzi Petrochemical utilizes the near-infrared analysis system for cracking raw materials and the real-time optimization system for cracking depth to optimize and control the cracking furnace outlet temperature so that different raw materials are different. At the same time, the best temperature control is obtained on the furnace type. At the same time, the flare gas is periodically sampled and analyzed, and the change of the high value-added material content in the flare gas is routinely monitored, and the leakage point is timely checked and eliminated, thereby minimizing the discharge of high value-added materials. , effectively control the loss of high value-added products within the design range.
