Yangzi Petrochemical keeps a close eye on changes in market demand and adjusts product output

China Petroleum & Chemical News Network News Since this year, Yangzi Petrochemical has been closely following changes in market demand, optimized and adjusted the output of various products such as refining, olefins, aromatics, plastics, etc.
, increased production of high value-added products with strong market demand, reduced production of products with sluggish market demand, and coordinated the company as a whole Resources to play a good and effective whole game of chess
.

From January to June this year, Yangzi Petrochemical's output of gasoline, asphalt, and ethylene oxide increased by 3.
5%, 89.
9%, and 6.
57%, respectively, and ethylene glycol decreased by 11.
15% year-on-year
.

Through product optimization, good economic benefits have been achieved

Adjust oil production according to market demand

Since the beginning of this year, crude oil prices have risen, the market has gradually recovered, macroeconomic policies have tightened, and the oil product market has been volatile.
Yangzi Petrochemical has followed market changes closely, adjusted product flow in a timely manner, and increased production of gasoline, asphalt and other products that are in high demand in the market
.

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

One increase and one decrease of main products

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

However, the market of ethylene glycol products is not good, and the product is losing money, 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” measure of “alcohol” keeps close to the market and fights the “tough battle” of creating benefits
.

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, it adjusted the pH of the absorption system 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 technical research team of the ethylene glycol workshop runs as a follow-up to track, collect and monitor process parameters to solve new problems in a timely manner
.

In the first half of the year, both ethylene oxide and ethylene glycol, the two major products, maintained a 100% premium rate

　　Keeping an eye on the aromatics market, since February, in response to the rise in the benzene product market, we have taken measures to increase the production of benzene products from raw material adjustments, equipment tapping potential, and optimized operation.
The daily output of benzene has reached a historical high of 1,350 tons during the same period
.

　　High-quality and high-end plastic products

　　On March 3, 2021, the EVA device of Yangzi Petrochemical Plastic Factory opened up the whole process, and successfully produced qualified EVA products on May 6
.

As of the end of June, more than 10,000 tons of qualified EVA products have been produced

　　In response to the plastic product market, 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 quality, high-end, differentiation, and differentiation of polyolefin products.
Functional development
.

　　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 successfully 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 June this year, the company's production of special materials for new polyolefin products accounted for 68.
14%, which was the highest record in all years and achieved remarkable results
.
