气体分离的工业化工艺过程,经历了低温分馏、分子筛吸附、变压吸附等一系列发展阶段,而气体膜分离,作为一种新的气体分离技术,其问世特别是它的工业化应用,将使气体分离业发生再一次飞跃。每一次新技术的出现,都会给相关行业带来机遇,同时也向他们提出挑战。作为空分行业的排头兵,要想保持行业第一的地位,就必须具有对新科学、新技术、新工艺的高度敏感性,就必须在挑战到来之前做好心理上、技术上的准备,未雨绸缪,积极参与。只有这样,才能战胜各种危机,得到不断的发展。出于这样的考虑,我们根据刘茉莉等编著的《膜分离技术》一书,在这里对膜分离技术(主要是气体膜分离技术)作一简单介绍。
Gas separation industrialization process, has experienced a series of stages of development, such as low temperature fractionation, molecular sieve adsorption, pressure swing adsorption, and gas membrane separation, as a new gas separation technology, its advent, especially its industrial application, will make the gas Separation industry leap again. The emergence of each new technology will bring opportunities for related industries, but also challenge them. As the vanguard of the air separation industry, in order to maintain the No.1 position in the industry, it must have the high sensitivity to new science, new technology and new technology, so it must make psychological and technical preparations before the challenge comes and take precautions ,participate actively. Only in this way can we overcome all kinds of crises and get continuous development. For this reason, we make a brief introduction of membrane separation technology (mainly gas membrane separation technology) based on the book “Membrane Separation Technology” compiled by Liu Jali et al.
