49 flow charts to fully understand the refining and chemical plant

Refining and chemical integration enterprise

The refinery area generally includes the main production facilities such as atmospheric and vacuum distillation, catalytic cracking, diesel hydrogenation, residue hydrogenation, sulfur recovery, aromatics extraction, and a complete auxiliary production system. Production of gasoline, kerosene, diesel, lubricants and other products.

Chemical zone: Leading with ethylene plant. The refining naphtha, LPG (liquefied petroleum gas is a mixture of propane and butane, usually accompanied by a small amount of propylene and butene) and other raw materials are cracked by a cracking furnace to separate intermediate products such as ethylene, propylene and butadiene. .

The follow-up includes the production of high-density polyethylene, full-density polyethylene, high-pressure polyethylene, polypropylene, styrene, synthetic rubber and other major production equipment and a complete auxiliary production system and public engineering system.

This courseware contains 30 sets of refining and chemical equipment: catalytic reforming, aromatics extraction, gasoline hydrogenation, alkylation, diesel hydrogenation, catalytic cracking, mtbe, circulating water system, polypropylene, sewage treatment, sulfur recovery. .....
