Argon distillate compensation block parameters for air separation equipment

The small air separation units, large air separation units and liquid air separation plants use ambient temperature molecular sieve adsorption purification, pressurized turbine expander cooling, liquid oxygen evaporator pressurization, gauge packing distillation, and DCS system control of the self-pressurization process. All systems are operating normally. The regenerated molecular sieves were not thoroughly regenerated and a vicious cycle occurred, increasing operating costs and risks. Operati...

The main elements of the analysis and development of the overhaul programme were First open the upper manhole of the purifier and check the bed leveling situation. If the bed is uneven, rake the bed. Add a few more drums of new molecular sieves. If the bed is collapsed, the lower manhole needs to be opened. Depending on the location of the bed leak, first plug the leak. Then rake out the leaking molecular sieve and observe its colour. If the leaking molecular sieve is black and yellow in colour...
