Operation of cryogenic air separation equipment

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

Answer:It can be done, and there is just a public 7500nm ³/h (80% o ɑ) VPSA benchmark project: Jiangyin Huaxi iron making VPSA project Parameters: 7500nm ³/h, 80% oxygen purity, vpsa-7500 specification, smelting oxygen enriched condition, BOT mode, supporting their own blue bank intelligent operation and maintenance system Background: This is the VPSA project publicly announced by Deere air separation. Previously, Deere's main business was cryogenic air separation, and VPSA is a new product line. Key point differentiation (very important) 1. the 7500 is a single set of VPSA adsorption tower group, not multiple sets in parallel; Purity 80%, blast furnace/iron making oxygen enriched standard working condition 2. Deere does not take VPSA as its main business, and cryogenic is its strength; VPSA molecular sieve is purchased 3. capability boundary: at present, VPSA performance is publicly disclosed, and there is no case of a larger single set (≥ 10000) VPSA being publicly put into operatio
