  3. Abstract:
  4. Environmental restrictions, new transportation fuel specifications, and increased processing of heavier more-sour curds are leading substantial increases in refinery hydrogen consumption for hydrodesulfurisation, aromatic and olefin saturation and improvement of product quality and reduces in refinery hydrogen production from catalytic reformers as a by-product. Therefore above factors make hydrogen management, a critical issue. Generating, recovering and purchasing of hydrogen have significant impact on refinery operating costs. More importantly, overall refinery operations, may be constrained by the availability of hydrogen. Primary consideration, however, should be given to the recovery of hydrogen contained in various purge gasses, since this is a very attractive way from the viewpoint of economy. This paper discusses three process for recovery and purification of hydrogen: adsorption by using of pressure swing adsorption, permeation using membranes, cryogenic and then compares these options from the viewpoint of economy. Then, revamping of hydrogen distribution network will be studied using actual data of an refinery in four alternatives from viewpoint of economy
