The introduction of PSA proceses Is commonly attributed to Skarstrom' and Guerin de Montareuil and Domne2 in 1957- 1958. However, manv of the essential features of this type of process were delincated much earlier in the papers of Kahle3.4 and in the pioneering Datents of Hasche and Dargan,'Perlev.s and Finl avson and Sharp.7* which were filed berween 1927 and 1930 but have been argely overlooked by more recent authors. The Air Liquide process, developed by Guern de Montgareuil and Domine, uilized a vacuum swing. whereas the Esso process, pioneered by Skarstrom, used a low-pres-sure DurRe to clean the adsorbent bed following the blowdown slen. Details of both cycles, which are still n common use, are given in Chapler 3. Some other key dates in the chronologncal development of PSA technology are sum marized in Table l.
