At present, the increasingly cold weather in Lanzhou has brought challenges to the production and operation of refining and chemical industry. Lanzhou Petrochemical Company faced up to difficulties, insisted on "playing a game of chess" and all the staff worked hard to sprint the "last mile" of the annual task. From January to November, the company processed 7,806,800 tons of crude oil and produced 1,279,300 tons of ethylene, and its business performance continued to improve. Among them, ethylene production increased by 69,000 tons year-on-year.

Adhere to the bottom line of safety and environmental protection to ensure the smooth operation of the device. In view of the contradiction that acid water is difficult to be balanced under the high load operation conditions of refinery units, Lanzhou Petrochemical Company strengthened the corrosion control, and strengthened the acid water discharge control of each unit on the premise of meeting the anti-corrosion requirements of the unit, so as to keep the acid water generally stable. At the same time, the company compacts the responsibility of controlling the sewage source of each operation department, accurately controls the sewage treatment device, manages the sewage system as a production device, establishes a sewage inspection system, and monitors the sewage quality in real time to ensure the smooth operation of the sewage system, creating favorable conditions for the high-load and stable operation of the refining production device.

Accurately adjust the production process and improve the operation efficiency of the device. Lanzhou Petrochemical has strengthened control over key refining and chemical production devices such as atmospheric and vacuum distillation unit, heavy catalyst unit, ethylene unit, rubber unit, etc., and organized employees to strictly implement process discipline, conduct meticulous inspection, carefully supervise the trays and operate accurately, so as to ensure the stable and long-term operation of refining and chemical units and fully improve the operation efficiency. The company carried out a "one-stop" crude oil processing test, which reduced the crude oil inventory and storage tank operating costs. By strengthening the communication between upstream and downstream businesses, the receiving capacity of ancient light hydrocarbons and liquefied gas was significantly improved.

Keep a close eye on changes in market demand and increase production and efficient products. Lanzhou Petrochemical highlights the main line of maximizing benefits, keeps a close eye on the changing trend of market demand for chemical products, fully taps the potential of each set of devices, and strives to increase production and efficient products and enhance economic benefits. The company seized the favorable opportunity of the rubber market, carried out research on the long-term operation of rubber devices, and made every effort to increase production of rubber products. In October and November, the output of NBR exceeded 10,000 tons for two consecutive months, and the 150,000-ton/year styrene-butadiene rubber plant maintained a good trend of three lines in parallel for a long time. At the same time, Lanzhou Petrochemical fully organizes the production of fist products and high-end products. Since the beginning of this year, the Cpk index of differentiated and high-end products such as medical materials RP260, LD26D, automobile materials SP179 and floor heating pipe special material mPE3010 have all reached the highest level in history. The company opened up the supply of raw materials for small products and the back road of leaving the factory, and organized HSBC to transport the high-octane xylene components to the oil blending center as blending components, thus realizing the optimal utilization of resources and creating favorable conditions for increasing the production of high-grade gasoline. In November, Lanzhou Petrochemical produced 62,000 tons of high-grade gasoline, which better met the market demand and contributed to ensuring winter supply.
