The new aromatics extraction plant is one of the eight production facilities of the company's 1 million-ton/year ethylene renovation and expansion project. The total investment is 80 million yuan. After the completion of the transformation, the output of the plant products will be increased from 160,000 tons to 460,000 tons per year. Products include benzene, toluene, mixed xylene, and by-products such as raffinate oil. By the end of March, the device achieved intermediate transfer.
In order to ensure the safety goal of driving, Maoming Ethylene applied JHA (Work Hazard Analysis) template to identify hazards during production, human, machine, object, environment, etc. during driving, and proposed control and elimination measures to ensure that the device was driven. The achievement of safety goals. In order to reduce the driving cost and set new standards for the new devices, they have taken every step of the process operation from purge, airtight, stand-alone trial and intermodal transport to formal commissioning, and strictly controlled the quality of the driving process. Safe and economical drive laid the foundation.
At 10 o'clock on the April 18th, the new aromatics plant began to introduce solvents. At 13:00 on the 19th, the system began feeding materials. On the 22nd, it produced qualified products. On the 22nd, it broke through the entire process of the old and new devices, which was shortened by nearly 5 days compared to the original plan of 7 days. It has created a good level of domestic equipment of the same type from the time of feeding to the completion of the shortest time, and the minimum loss during the commissioning test, achieving the overall goal of safe and economical driving.
It is understood that the commissioning of the new aromatics plant will not only bring economic benefits of 3 million yuan per month to the enterprise, but also will serve as the largest aromatic hydrocarbon production facility in South China, and will further satisfy the increasing demand for aromatic hydrocarbons in the Pan-Pearl River Delta region. The local economy has far-reaching significance.
Maoming Ethylene Aromatic Hydrocarbon Installations Successfully Rebuilt and Expanded
The reporter recently learned from the chemical division of Maoming Branch of China Petrochemical Co., Ltd. that the first production unit of the company’s 1 million-ton/year ethylene renovation and expansion project—the new aromatic hydrocarbon extraction unit of 460,000 tons/year and the old installation lasted for 56 years. Hours, open up the whole process, and create the shortest driving level of the same type of equipment in the country from the time of feeding to the qualified product. This is also the largest set of aromatics production facilities in South China.
