Shaanxi Xinghua Group's Technological Transformation Projects, Design Of Air Separation

The paper describes the development general situation and the development direction of the air separation technology in present. And introduced the item to design the principle of 4# air separation reform in Shanxi xinghua groups co. principle and design concerning equipments calculation, choosing of equipments type, crafting the pipes discharge design calculation, the strength of the crafting pipe design calculation. Discussed the adoption liquid the ammonia to prepare cold and efficiently molecular sieves the decontamination air separation the process's superior and boost production to reform the result. Finally pointing out the foreground of its development.Should reform the item to set up circulate two in the last years, actual oxygen yield amount to 7000 Nm~3/ h, nitrogen spirit yield is 12500 Nm~3/ h, exceeded to expect the target. the pure degree of oxygen attain 99.96%, the pure degree of nitrogen spirit come to a 99.99%, liquid argon yield 75 Nm3/ h, come to a to design the target.
