摘要
降本增效涉及项目的设计、采购、施工、运行维护等全生命周期,工程设计是天然气净化项目降本增效的关键环节,在设计阶段项目降本增效的主要途径是降低工程投资和节能降耗。围绕天然气净化项目的脱硫、脱水、硫黄回收及尾气处理等工艺过程,对工程设计阶段降本增效的措施进行探讨,得出:通过优化全厂整体工艺方案、工艺装置工艺方案、工艺流程,合理选用设备、阀门,施工图采用多专业协同三维设计,多方联合审查三维模型,推广模块化设计等措施可优化设计,降低投资;通过优化脱硫装置、脱水装置、硫黄回收装置、尾气处理装置及其它措施可优化设计,降低能耗。该研究结果可为天然气净化项目的降本增效提供借鉴。
Cost reduction and efficiency enhancement involve the whole life cycle of project design, procurement, construction, operation and maintenance. However, engineering design is the key link of cost reduction and efficiency enhancement in natural gas purification project. The main way of cost reduction and efficiency enhancement in design phase is to reduce project investment, save energy and reduce energy consumption. The measures of reducing cost and increasing efficiency in engineering design stage are discussed with regard to the process of desulfurization, dehydration, sulfur recovery and tail gas treatment of natural gas purification project. It is concluded that design can be optimized and investment be reduced by optimizing the overall process plan, process plan and process flow of the plant, properly selecting equipment and valves, practicing inter-discipline collaborative 3D modeling in construction drawings, and performing joint examination for 3D model, promoting modular design and other measures. The design can be optimized and energy consumption can be reduced by optimizing desulfurization device, dehydration device, sulfur recovery device, tail gas treatment device. The results can provide reference for reducing cost and increasing efficiency of natural gas purification projects.
