High Level Metal Calcined Petroleum Coke

A process method for calcining petroleum coke produced by coke oven is characterized in that it uses delayed petroleum coke and asphalt as raw materials, and is composed of four systems: raw material pretreatment, coke oven dry distillation calcination, product post-treatment and gas purification. Because it solves the problem of producing calcined petroleum coke with coke ovens, the quality of calcined petroleum coke is significantly improved.

1.A coke oven production calcined petroleum coke process method, which is characterized in that delayed petroleum coke and asphalt are used as raw materials, and is composed of four systems of raw material pretreatment, coke oven dry distillation calcination, product post-treatment and gas net production: raw material treatment system, delayed petroleum coke and asphalt are pre-crushed respectively, and the proportion of delayed petroleum coke weight ratio of 70-99% and asphalt weight ratio of 1-30% is blended with an electronic belt scale, and then mixed and crushed, and the part with a particle size of less than 3mm ≥ 60%; In the coke oven dry distillation system, the pretreated raw materials are sent to the coke oven for high-temperature dry distillation calcination, the calcination temperature is controlled to be 950-1350 °C, the coking time is 12-26 hours, and the mature coke is cooled and quenched, and the coke quenching time is 10-250 seconds, so that the coke temperature ≤ 100 °C; The product post-processing system, calcined petroleum coke after furnace, the particle size is whole, crushed and screened, and the particle size requirements of 0-150mm are met by crushing and screening, and then packaged or shipped in bulk; In the gas purification system, the gas produced by high-temperature dry distillation and calcination enters the blast condensing system from the coke oven, and is sent out after the gas-liquid separator, condenser, primary cooling tower, blower, electric capture tower and final cooling.
