China Petroleum Network News (Special Correspondent Wei Jianyi, Correspondent Lei Weiwei) On January 2, the reporter learned from the relevant departments of Sichuan Petrochemical that the company's 800,000 tons of diene cracking unit in 2019 exceeded 870,000 tons of diene, a record since the start of production in 2014 The highest level. At the same time, the annual diene yield is the highest 32.70%, the diene yield is the highest 49.55%, the diene energy consumption is 539 kg standard oil/ton, and the processing loss is 0.11%, which are both at the advanced level of the industry.

In 2019, Sichuan Petrochemical focused on the group company's requirements for "stabilizing plant operation, increasing product yield, and reducing production energy consumption", in-depth implementation of ethylene plant compliance management and quality improvement and efficiency, and fully organized high-load production, production and operation remained stable, safety and environmental protection were comprehensive Under control, economic benefits continue to grow.

Speed up structural adjustment and technical research, add a methane-hydrogen compressor to the diene unit to use the excess methane-hydrogen by-product of the recovery unit as fuel, thereby eliminating the restriction on production capacity due to the excessive load of the tail gas rectification tower and reducing flare emissions. Achieve 105% load operation of the device, which greatly improves the economic benefits and product yield; by adding a cracking furnace air preheater, the air that was directly supplied to the furnace is preheated, thereby reducing fuel usage and reducing device energy consumption.

Strengthen the refined management of the production of diene, resolutely implement the "four and one card" requirements for production change operations with instructions, procedures, confirmation, supervision, and card-based production, continue to deepen the "three bases" work, and realize the first line of production Intelligent inspection management system is fully covered; APC advanced control module is added to further optimize the automatic control rate of the system, improve the stability rate of ethylene equipment, and reduce production fluctuations caused by human operation; through shift shift competitions, HSE quantitative competitions, centralized lectures by engineers, and young workers process Narration and other activities mobilize the enthusiasm of all employees for production, and lay a solid foundation for the stable, long-term and excellent operation of the device.
