Analysis of Heat Balance of MH Separator

Abstract

The paper deals with the thermal balance of a metal hydride separator, primarily a tank containing a metal hydride alloy subjected to heating and cooling processes caused by absorption and desorption. As during the equipment operation it is necessary to ensure heating and cooling, the amount of the required heat to be supplied and removed must be identified. The article also deals with hydrogen separation from undesired components of synthetic gas which is formed in a plasma reactor during the waste gasification process.

Analysis of the Heat Balance of a Metal Hydride Separator Used for the Separation of Hydrogen from Syngas

“…Global warming belongs to the best-known threats to sustainable development [1]. A reduction of greenhouse gas emissions is the way to slow it down, and this was the target to which 194 countries committed by signing the Paris Convention, with the aim to maintain global warming below the limit of an increase in the average global temperature of a maximum of two degrees Celsius.…”

“…Gasification and melting of organic wastes in an inert atmosphere, or with the addition of a substoichiometric amount of an oxidising agent, results in the production of combustible gaseous components, such as CO, H 2 , and CH 4 , and their contents in syngas (SG) are significantly affected by the waste composition and the boundary conditions of the thermal process (atmosphere type, operating pressure, temperature, time, etc.) [1,2,14]. Due to the high temperatures generated by a plasma arc, independently from the partial pressure of oxygen, the organic components of the waste decompose into simple gaseous compounds.…”
