A few days ago, the reporter was informed that the Lanzhou Petrochemical Coking Processing Co., Ltd. mixed ethylene heavy oil project after nearly two months of operation, the current blending gradually stabilized, ethylene cracking heavy oil has achieved continuous processing.
It is understood that ethylene pyrolysis heavy oil is a by-product of the pyrolysis and condensation of ethylene plants and is difficult to process and use. It is generally sold at low prices as a fuel oil. To further optimize resource protection, it actively promotes the comprehensive utilization of black products, and Lanzhou Petrochemical accelerates the implementation of this project. Resources are dried and squeezed to increase the added value of products. Since November 30 last year, ethylene heavy oil coking units have entered the industrial trial production stage.
During the operation process, Lanzhou Petrochemical conducted a comprehensive inspection of all aspects of the transfer and processing process in response to the pumping problem of the raw material pump, changing the 10,000-meter tank oil intake method from up to down, and sending the pump inlet from the bottom of the pumping tank to the ethylene plant. Direct delivery, smooth solution to water problems and leakage of dynamic mixer seals, etc. Production equipment management technology and operators are meticulously fine-tune, differential pressure on heat exchanger, pressure drop in fractionation tower, coking in heating furnace, hydrogenation of diesel hydrogenation unit The dynamic pressure monitoring of the reactor pressure drop changes, etc., to resolve the abnormalities in operation at any time, and effectively ensure the normal and stable operation of the device.
