After 4 months of shutdown transformation, January 5, Yangzi Petrochemical Olefins Plant 1 set of ethylene plant cracking furnace No. 10 to complete energy-saving standard transformation to achieve ignition oven, feeding a successful car.
1 sets of ethylene plant 10 cracking furnace energy-saving standardization transformation is the Yangtze Petrochemical Company in 2017 one of the major transformation projects, started on September 12, 2017, December 25 in CCC, January 5, 2018 drove, lasted 116 days.
Period, the completion of the old furnace steel structure, waste heat boilers, radiant section of the furnace, the convection section module, the bottom of the burner and other equipment and ancillary pipeline removal work; replacement and installation of a new steel structure, waste heat boilers, furnace tubes, burners, etc. Equipment and new process pipeline; completed the pipeline anti-corrosion insulation, construction 'three check four set', tail rectification work.
After the project was handed in, the project team worked together with the olefin plant to continuously improve the construction of the No.10 furnace and to start the preparation of the "Three Checks and Four Sets" of the No. 10 furnace reconstruction project, rectifying and perfecting the rectification and design leakage at the end of the construction control project, In accordance with the 'December 30, 2017 No. 10 furnace pre-ignition oven, January 4, 2018 officially oven, January 5 dosing drive' three control requirements, tight, Production preparation.
In order to ensure the reformation of furnace No.10 after ignition, feeding a successful car, Yangzi Petrochemical ethylene plant ethylene plant developed a No. 10 furnace ignition process heating operation card and feeding driving program, check the conditions of the ignition oven to confirm strict Furnace heating process control, as well as feeding car technology, equipment and electrical instrument professional inspection to confirm the work, at the level of implementation of the person in charge.Especially the key points of the ovens operation, ovens temperature control process and super high pressure steam pipeline system purge steps, Olefins plant to develop operational considerations, and organize post training operators to learn, know and master.According to the safety risk of firing oven heating and feeding and driving process after the reformation of No.10 furnace, the safety analysis of JSA for ethylene plant of ethylene plant, Implement safety risk prevention and control measures.
At 15:30 on January 5, No. 10 furnace with the conditions of feeding, a set of cracking positions operating personnel strictly implement feeding driving instructions, in accordance with the procedures for feeding car meticulous operation, carefully before and after the process of feeding well.At the same time, olefin plant Strengthen the on-duty transportation and timely coordinate and solve related problems, ensuring the safe and steady operation of furnace No.10.
At present, No. 10 furnace runs smoothly. The Yangtze ethylene unit maintains 1 set of '4 + 3' and 2 sets of '4 + 0' mode with high load and stable operation. The cracked gas volume per hour reaches 230,000 standard cubic meters and the daily ethylene production is over 2,200 tons , To achieve high-load safe production.
