AM-94-23 COST- EFFECTIVE UPRATING OF EXISTING HYDROGEN PRODUCTION UNITS

Description:

The demand for supplemental hydrogen production in refineries is growing significantly worldwide as environmental legislation concerning cleaner gasoline and diesel fuels is introduced. The main manufacturing method for this hydrogen uses the well-proven steam reforming process route. This article lists the advances in catalysts and technology in this area, and shows how they can be applied to existing hydrogen plants in order to maximise throughput. Such retrofit options are generally more cost-effective than the construction of a new hydrogen plant: due to the diversity of hydrogen plant designs and feedstocks used, however, a case-by-case evaluation is needed to determine the best options for a particular plant.
