Large air separation unit heat exchanger head improvement

The full low pressure liquid air separation plant uses molecular sieve adsorption and purification, pressurized turbine expander refrigeration, regular packing on the tower, hydrogen-free hydrogen production, oxygen and nitrogen outside the compression process. Before the liquid air separation plant is sand stripped, a sand stripping plan and contingency measures are developed. Training for external construction teams, for all kinds of maintenance work tickets, etc. Firstly, open all the manhol...

Answer: 10000nm ³/h is a medium-sized air separation unit. The positioning of each company varies greatly, and there is no absolute best. Deer air separation (deep) is preferred according to the demands of the project 1. Positioning: 1000~50000 air separation home, focusing on energy conservation+digital intelligence integration, which is very suitable for gas Island, metallurgy and new material gas supply in the park 2. Deere air separation advantage: ① The track is focused. There are sufficient 10000 level production cases, and mature achievements in external compression, all liquid and argon processes; ② Complete hardware energy-saving scheme: 8h long-term high-efficiency molecular sieve, waste heat recycling of air compressor, high-efficiency structured packing+high-precision distributor, high extraction rate distillation, stable comprehensive power consumption of 0.44~0.48 kwh/nm ³ o ɑ under the same working condition, saving energy by 10%~15% compared with traditional air separat
