Refinery hydrogen management---cost analysis of chemically-integrated facilities. G.P. Fowler et al. Ind. Engng. Chem. Res., July 1996, 35(7), 2378--2388.

A method for economic assessment of hydrogen resources is developed by analogy with heat recovery. The effectiveness of hydrogen use is related to the cost of hydrogen recovery and the value added in hydrogen-consuming processes. Costs of hydrogen recovery by pressure swing adsorption and by membrane permeation are described. Value added in hydrogen-consuming processes and the availability of hydrogen are determined by the process chemistry and prevailing economic conditions. Graphs of availability and distribution of hydrogen resources are presented which may be used in refinery design in conjunction with optimization by linear programming. The method is illustrated by case studies. 32 refs.
