- 为了降低天然气净化过程的能量消耗和操作成本，对天然气脱硫过程建立了优化模型和优化方法。借助HYSYS软件，应用该优化模型和优化方法对中国石油西南油气田公司川中油气矿磨溪天然气净化厂50×104 m3/d净化装置的脱硫工段进行模拟计算和参数优化。经过优化后，在保证净化气产品质量的前提下，净化装置的脱硫工段的能耗比优化前降低了12.35 %，经济效益显著。该优化模型和优化方法通用性强可运用于其它过程系统操作参数的优化。
In gas purification process， desulfurization process has more energy consumption than dehydration. In order to reduce energy consumption and operation cost， established are an optimization model and an optimization method for gas desulfurization process. With the aid of the software Hysys， applied are the model and method to conduct simulation calculation and parameter optimization for the desulfurization process of 50 × 104m3/d purification unit in Moxi gas purification plant of PetroChina Southwest Oil and Gas Field Company Chuanzhong Oil and Gas Well Area. After optimization， energy consumption of the desulfurization process in the purification unit is 4842.78kW， 12.35 % less than that before optimization while the purified gas quality is ensured， which shows that energy consumption is reduced largely and economic benefit is remarkable. The optimization model and method have good applicability and can be applied in process parameters optimization of other process systems.
