In November, the single-day ethylene oxide production capacity of Zhenhai Refining & Chemical's ethylene oxide/ethylene glycol plant exceeded 640 tons, and the monthly output reached 18,900 tons, both hitting a record high in the past ten years. The plant maintained a stable, safe, high-yield situation. .
Recently, the device has carried out high-load production calibration, explored the best operating conditions of the device, and provided technical support for the deep excavation of the maximum production capacity of ethylene oxide. During the production process, in view of the high load of the ethylene oxide purification tower and the low load operation bottleneck of the ethylene glycol refining system, the plant technical team optimized the working conditions of the lithium bromide condensing unit, optimized the reflux ratio of the ethylene oxide purification tower, and the operation of the dealdehyde bed. Measures to ensure product quality and gradually increase the production of ethylene oxide. At the same time, Olefin I, in an organic linkage with the Planning Department and the Quality Control Center, optimized the ethylene oxide delivery method, and achieved efficiency improvement in ethylene oxide loading.
