Title: Use and Optimization of Hydrogen at Oil Refineries Author: A.Lafleur Subject: Use and Optimization of Hydrogen at Oil Refineries presentation by Aimee LaFleur, Shell, at the [email protected] Scale Workshop, held May 23 24, 2017, in Houston, Texas.

Hydrogen for refineries is increasingly provided by

Because the growth in supply of hydrogen used at refineries has come from these industrial gas producers rather than on-site production, the amount of natural gas feedstock consumed by refineries to make hydrogen has changed very little (decreased by 1% from 2008 to 2014) even though refineries' total hydrogen use increased 60% in the same period. If the increase in refiners' hydrogen

Hydrogen in Refining Demand for hydrogen will increase in the upcoming years as a result of stricter environmental legislation. Not only legislation but more extensive processing of residues and higher diesel demand compared with petrol will also increase hydrogen's demand. There are various hydrotreating processes in a refinery. To name a few: Hydrodesulphurisation: sulphur compounds are
