On September 8, exciting news came again from Yulin, the last production unit of the ethane-to- ethylene project of PetroChina Lanzhou Petrochemical Changqing, 30,000 tons/year butene-1 unit at 9:58 The catalyst injection started, and qualified butene-1 products were produced at 13:36. The successful start-up of the plant marked the completion of the company’s 800,000-ton ethane-to-ethylene plant and a perfect ending.
As the first industrial application of China Petroleum's own technology, the butene-1 unit has the production function of butene-1 and ethylene-1 with flexible switching of two products The operating conditions and production requirements are relatively harsh. The water and oxygen content in the production system cannot be greater than 3 PPM. There is no similar device in China to refer to, and there is no successful experience to learn from. In order to ensure a successful start-up of the device, the company's leaders came to the front line to coordinate and organize all forces to form a joint force to overcome difficulties, solve the problems encountered in the preparation stage of the start-up, and create conditions for the smooth start-up of the device.
During the start-up process, the majority of participating cadres and employees actively summarized the 800,000 tons/year ethylene plant, 400,000 tons/year high-density polyethylene plant, 400,000 tons/year high-density polyethylene plant /Year full-density polyethylene plant to achieve a successful start-up experience, unite and fight, make persistent efforts, steadily and steadily, standardize and make preparations for the feed and start-up of the butene-1 plant, and provide strong support from the patentee, design unit technicians, and start-up experts We carefully reviewed the start-up plan, comprehensively rectified and found problems, continuously strengthened the skill training of position employees, further improved the emergency operation plan, adopted the start-up plan of using ethylene to simulate operating conditions, and added a catalyst after the production operation is stable, which effectively reduces the risk of start-up. Loss of energy and material consumption. Especially in difficult tasks such as key equipment application, circulating pump selection, and process external circulation heat removal, the company gives full play to the technical advantages, professional advantages, and collaboration advantages of the start-up team.The problems will be solved one by one to ensure the intrinsic safety of the device and consolidate the production basis for long-term stable operation.
It is reported that the market demand for butene-1 and ethylene-1 products is strong. With the launch of the butene-1 product of the Yulin Ethylene Project on the market, it will certainly play an important role in improving the quality and efficiency of Lanzhou Petrochemical and building a high-quality development demonstration enterprise in the Yellow River Basin.
