摘　　要：针对煤化工装置对气体产品的新要求,从流程选择、优化、节能和安全供气等方面对大型化工型内压缩流程空分设备进行了研究;指出:合理选择单套空分设备规模,发挥多套空分设备联合供气的最大优势;合理、优化改造全精馏无氢制氩系统;设置安全、可靠的液体汽化后备系统;用液体膨胀机代替高压节流阀,是大型化工型内压缩流程空分设备的新特点和发展方向。Based on new demand on gas product from coal chemical apparatus, investigation has been made on internal compression air separation unit in view of process option, optimization, energy saving and safe gas supply. The discussion focuses on new characters and future trends of large scale internal compression air separation unit for chemical industry, including the advantage of combined gas supply by multiple units with a proper capacity of single unit, the optimizing modification of full-rectification hydrogen-free argon producing system, the safe and reliable back-up liquid vaporizer, the replacement of high pressure throttling valve by liquid expander.
