延迟焦化装置吸收稳定系统工艺模拟及操作优化
Process Simulation and Operation Optimization of Absorption/Stabilization System in Delayed Coking Unit

本文采用Aspen模拟延迟焦化装置吸收稳定系统确定影响吸收稳定系统效果的主要因素，通过模拟优化操作参数，同时技改投用溴化锂机组，优化工艺，实际效果良好，干气中液化气的含量由2.5%降低至0.5%以下，提升了干气质量，同时增收液化气产率。
Aspen was used to simulate the absorption and stabilization system of delayed coking unit to de-termine the main factors affecting the effect of absorption and stabilization system. The operation parameters were optimized by simulation. Meanwhile, lithium bromide unit was used to optimize the process. The actual effect was good. The content of liquefied gas in dry gas was reduced from 2.5% to 0.5%, which improved the quality of dry gas and increased the yield of liquefied gas.
