阅读说明：本技术 一种基于深冷精馏工艺生产空气产品的方法及空分系统 (Method for producing air product based on cryogenic rectification process and air separation system ) 是由 赵伯伟 布里格利亚·阿兰 薛凤杰 于 2017-12-28 设计创作，主要内容包括：一种基于深冷精馏工艺生产空气产品的方法及空分系统,在现有的深冷精馏工艺设备中增设空气产品导出管路(113)及液空增压泵(1131),利用现有精馏设备制备富氧液空,将原料空气增压、降温液化,还可根据客户需求,调配原料空气与富氧液空的比例,经液空增压泵(1131)增压至目标压力,经换热设备与精馏产生的气体或液体产品换热汽化后,制备高压或超高压的空气产品。在精馏生产氧、氮气体或液体产品的同时,可根据客户需求提供高压或超高压的空气产品,且无需设置额外的空气压缩机或被动地提高空气增压机的排压,极大地降低了生产成本,提高了能效水平。尤其是在需要生产少量的高压/超高压空气产品时,还可提高装置的稳定性。(A method for producing air products based on cryogenic rectification technology and an air separation system are characterized in that an air product leading-out pipeline (113) and a liquid air booster pump (1131) are additionally arranged in existing cryogenic rectification technology equipment, oxygen-enriched liquid air is prepared by utilizing the existing rectification equipment, raw material air is pressurized, cooled and liquefied, the proportion of the raw material air and the oxygen-enriched liquid air can be adjusted according to customer requirements, the raw material air is pressurized to a target pressure by the liquid air booster pump (1131), and high-pressure or ultrahigh-pressure air products are prepared after heat exchange and vaporization are carried out on gas or liquid products generated by rectification through heat exchange equipment. When oxygen, nitrogen gas or liquid product are produced by rectification, high-pressure or ultrahigh-pressure air products can be provided according to customer requirements, and an additional air compressor or the pressure discharge of an air supercharger is not required to be arranged, so that the production cost is greatly reduced, and the energy efficiency level is improved. Especially when a small amount of high/ultra high pressure air product needs to be produced, the stability of the device can be improved.)
