Maoming Petrochemical Company increased the temperature of the distillation and slag-removal device, so that the coking device can currently process 500 tons of residual oil per day and create more than 12 million yuan of profit each month.
As the company's coking unit processing capacity gradually increased, the heating furnace load is a major constraint. For this reason, the company's oil refining sub-unit combined with the fourth workshop was the first to stop the distillation unit of a set of coolers, so that the coking unit hot residue feed increased from 124 °C to 134 °C, greatly reducing the coking unit heating furnace load, coking Device processing volume increased by 3%. On this basis, they also suspended the two heat exchangers of the distillation unit, which further increased the temperature of the hot residue feed to 137°C. This not only reduces the company's residual oil inventory, but also increases the light oil yield and comprehensive commodity ratio.
