Recovery of hydrogen from gas streams
WebbThe amount of hydrogen from the main ROG stream in a refinery may be seen in Table 1. The remaining streams are hydrocarbons ranging from CH4 to C6+, some of which represent a benefit to the refinery and can also be recovered. The amount of hydrogen in the fuel gas system of a refinery can reach 40%. WebbTherefore, the recovery of hydrogen from waste gas stream must be considered among the most environmentally friendly options, appearing competitive versus complex processes like supercritical water gasification, chemical looping, advanced methane cracking, or tri-reforming [25,58,59].

WebbThe recovered hydrogen is now returned to the process, thus reducing the total hydrogen consumption by 40 per cent. Because hydrogen is cheap to produce it is often not thought economic to recover and recycle the gas from waste gas streams. WebbEmbodiments of the disclosure provide a method and system for sulfur recovery. A Claus tail gas stream is fed to a hydrogenation reactor to produce a hydrogenated gas stream. The
WebbMembrane technology: Hydrogen enrichment using membrane technology is one of the economical methods to recover hydrogen from off-gases due to low costs (i.e., operating and capital) and ease of operation [8]. The Membrane technology is based on the selective separation properties of a polymeric membrane. Webb31 dec. 1995 · The effective use and recovery of hydrogen from the major hydrogen-containing streams in the refinery is an important strategy to meet the refining demands of the 1990`s. Hydrogen upgrading in refinery applications can be achieved by pressure swing adsorption (PSA), selective permeation using polymer membranes, and cryogenic …
