Yangtze Petrochemical: Play a good and effective whole game of chess

Since the beginning of this year, Yangzi Petrochemical has optimized and adjusted the output and quality of various products such as refining, olefins, aromatics, plastics, etc.
, and coordinated the company by adjusting production plans and product distribution, changing equipment production strategies, and creating "product giants" with independent characteristics.
Overall resources, play a good and effective whole game of chess

Adjust the product distribution and recovery rate

Adjust the product distribution recovery rateadjust the product distribution recovery rate

Since the beginning of this year, the price of crude oil has risen, the market has gradually recovered, and the oil product market has been volatile.
Yangzi Petrochemical adjusted the product flow in a timely manner to increase the production of gasoline, asphalt and other products
.

Yangzi Petrochemical formulated an optimization plan for increasing gasoline production and established a research team
.

Carry out precise control according to the changes in the nature of crude oil, dynamically adjust the gasoline dry point, and find ways to produce more gasoline and increase profits

In response to the situation of better road asphalt market benefits, Yangzi Petrochemical seized the opportunity to increase the total road asphalt production and go all out to do a good job in asphalt production
.

The company also reduced production costs by optimizing the ratio of raw materials, exploring multiple paths for the production of asphalt from inferior crude oil, and developing optimization methods for the production of road asphalt with new oil types, and obtained suitable shallow extraction, deep extraction, mixing, blending, etc.

Affected by the epidemic, the jet fuel market demand has been sluggish this year
.

According to the characteristics of the process flow of the plant, Yangzi Petrochemical optimizes the process parameters by adjusting the production plan and product distribution to increase the yield of diesel and naphtha, and reduce the yield of jet fuel

The high-quality product rate maintains 100%

　The rate of high-grade products is maintained at 100%　.
The rate of high-grade products is maintained at 100%.

"Ethylene oxide market is good, both volume and price are rising.
Increasing production means increasing efficiency
.

The market for ethylene glycol products is not good, and product loss, and production reduction is also reducing loss and increasing efficiency

In the first half of this year, in view of the relatively good profitability of ethylene oxide and the poor efficiency of ethylene glycol, the company adjusted the production strategy of ethylene glycol equipment with the goal of maximizing benefits, and implemented "increasing ethylene oxide production and reducing ethylene oxide production".
The “one increase and one decrease” measures of “alcohol”
.

Yangzi Petrochemical optimized and adjusted the production ratio of ethylene oxide and ethylene glycol.
On the one hand, it optimized the final production operation of the catalyst.
On the basis of scientifically and rationally adjusting the ethylene oxide hydration ratio, the pH value of the absorption system was adjusted to reduce the production rate of ethylene glycol.
On the other hand, according to temperature changes, strictly control the reaction temperature and pressure, so that ethylene oxide can maintain a stable and high-yield momentum
.

In response to the product quality control problems caused by the adjustment of product structure, the ethylene glycol workshop research team followed up to track, collect and monitor process parameters, and solve new problems in a timely manner
.

In the first half of the year, the premium grade rates of ethylene oxide and ethylene glycol both maintained 100%

　　On March 3, the EVA device of Yangzi Petrochemical Plastics Plant opened up the whole process, and on May 6 successfully produced qualified EVA products
.

As of the end of July, a total of about 15,000 tons of qualified EVA products have been produced

　　Yangzi Petrochemical has concentrated its strengths to accelerate the creation of a group of "small product giants" with independent characteristics, promote the modification and customization of polyolefin products, and promote the development of polyolefin products in the direction of quality, high-end, differentiation, and functionality
.

　　The company adheres to the production principle of combining "production based on demand" and "production based on efficiency", optimizes and adjusts the production plan of special materials for new polyolefin products, and produces more high value-added products
.

Together with post-processing users, they vigorously accelerate the pace of new product development and finalization through market research, technical program demonstration, optimization of process conditions, and improvement of auxiliary formulations, and strive to achieve new breakthroughs in the development and production of special materials

　　In early April, Yangzi Petrochemical completed the first production task of metallocene grades this year, producing a total of 4 grades of 13,000 tons of qualified metallocene polyethylene products, setting three new records for continuous production time, output and variety
.

At the same time, the company's new polyethylene lithium battery diaphragm material achieved high-volume production, completing 336% of the plan; the polypropylene pipe material special material doubled the planned output; EVA products exceeded 10,000 tons, and the effect was remarkable

　　From January to July this year, the company's production of special materials for new polyolefin products accounted for 66.
72% of the total, with remarkable results
