Yangzi Petrochemical crude oil entering the plant exceeded 10 million tons 2018-12-05 Source: Sinopec News Network As of the end of November, the crude oil entering the Yangzi Petrochemical Storage and Transportation Plant from pipelines and waterways this year has reached more than 11 million tons, which has better met the production needs of the company's refinery. After three rounds of transformation, the crude oil processing capacity of the Yangzi Petrochemical Refinery has been increased to 1,250 tons/year. In order to ensure that the upstream equipment can operate at full capacity and create profits, the storage and transportation plant has taken various measures to carefully organize the entry of crude oil into the plant, and at the same time strengthened the control of crude oil quality to ensure that the equipment can get "fine grain". Optimize crude oil procurement and scientifically adjust the crude oil structure. In June and October this year, based on the adaptability of the refining equipment, the company introduced two new oil types, Mars crude oil and Lapa crude oil from the United States, which are highly cost-effective. This not only filled the shortcomings of the original refining crude oil structure, but also reduced the cost of crude oil procurement. Strengthen crude oil quality and measurement supervision to ensure that crude oil benefits are not lost. Crude oil is the largest liquid material of Yangzi Petrochemical, with an annual demand of more than 10 million. If the moisture content is 0.1 percentage points more, tens of thousands of tons of crude oil will be lost. In March this year, the company established a crude oil supervision class to implement 24-hour continuous quality analysis and measurement tracking of crude oil entering the plant, so as to control the quality and measurement of crude oil from the source. Implement optimization and transformation of the crude oil system to ensure efficient production of the refining unit. The storage and transportation plant optimized the crude oil blending system by organizing the renovation of the low-flow blending facilities of heavy oil. ； By upgrading the crude oil storage tanks, using high-efficiency sealed floating roofs and floating plates, replacing the central drainage pipe, improving the heating system of the crude oil storage tanks and pipelines, and using high-standard storage and transportation facilities to ensure the quality of crude oil. Strengthen the quality control of the crude oil transfer process to ensure the smooth operation of upstream devices. If the crude oil contains water, it will cause operational fluctuations in the production equipment, and in severe cases, it will cause "tower flushing" and damage the equipment. The storage and transportation plant has specially issued crude oil quality management regulations, requiring that each batch of crude oil must be carefully cut before being returned to the device. Crude oil that does not meet the water gauge is strictly prohibited from being transported to the device. Effective control measures not only ensure the supply of crude oil in quantity, but also ensure the improvement in quality of crude oil, providing a reliable guarantee for the company's crude oil production and refining.

At the end of October, the Yangzi Petrochemical Refinery's heavy oil lightening transformation project was fully put into operation. The project can convert inferior residual oil into light oil through thermal cracking, and then further separate the light oil to produce high value-added products such as gasoline, diesel, wax oil, dry gas and liquefied gas.
Since the beginning of this year, the market demand for ethylene products has been large and the market benefits have been good. Yangzi Petrochemical has closely followed the market demand, ensured the safe and stable operation of the ethylene combined unit at high loads, and made every effort to increase ethylene production. In the first 10 months of this year, ethylene production increased by 36% year-on-year, setting a record high. Increasing ethylene production is one of the main goals of Yangzi Petrochemical Olefins Plant this year. Since the beginning of this year, the plant has implemented full-process optimization of ethylene in terms of raw material structure and production organization. It has closely monitored the changes in ethylene raw material structure and quality, tracked and analyzed, and strengthened predictions to ensure the high-load and long-term stable operation of the ethylene combined unit, achieving a new breakthrough in ethylene production.
“After three rounds of transformation, the Yangzi Petrochemical Refinery’s crude oil processing capacity has been increased to 1,250 tons/year.” When the Yangzi 300,000-ton ethylene project started construction in 1983, it was equipped with 5 million tons of refining equipment. In a round of transformation in the early 1990s, ethylene was transformed from 300,000 tons per year to 400,000 tons per year. However, the 5 million tons per year atmospheric and vacuum unit was downsized and could not reach the capacity of 5 million tons. In the second round of transformation at the beginning of this century, ethylene was transformed from 400,000 tons to 800,000 tons per year. The refining scale did not increase. Naphtha needs to be supplied from the Jinling Petrochemical Refinery across the river. In the three rounds of transformation in the past few years, 8 million tons of new refining units were built, so the refining capacity reached 12.5 million tons per year.
