“…The SO2 and the remaining H2S then reacts in the furnace and in a series of reactors to produce elemental sulfur. The overall removal efficiency of a Claus Process is dependent on the number of catalytic reactors installed [5,6,7].…”

“…Consequently, alkali vanadates are added to the solution to promote the oxidation. Since vanadium is toxic, the main drawback to the Stre t f o rd Process is that the process must be designed to handle the sulfur cake, and the disc h a rge solution [8]. The Stre t f o rd Process is modified to avoid the generation of toxic waste by using chelated iron to promote the reaction between H2S and dissolved oxygen.…”

“…To upgrade the crude SNG, CO 2 must be removed. There are various techniques to remove the CO 2 : absorption using either chemically active solvents or solvents that interact via physical interactions with CO 2 , adsorption on solid surfaces, membrane permeation, cryogenic fractionation and methanation [3][4][5]. Different design approaches and process layouts for CO 2 capture from crude SNG with membranes exist [6][7][8].…”

“…Chemical absorption processes employing primary alkanolamines, such as methanolamine (MEA), have already been used in several industrial processes for over 50 years [3,4]. The absorption process is based on the exothermic reaction of CO 2 from flue gas and amines in the solvent via a zwitterion mechanism to form carbamates.…”

“…The absorption process is based on the exothermic reaction of CO 2 from flue gas and amines in the solvent via a zwitterion mechanism to form carbamates. Therefore, heat is required for solvent regeneration [4], and the development and use of amine-based solvents with lower energy requirements for regeneration, along with enhanced reaction kinetics and mass transfer properties, is a major research priority. The heat required for the solvent regeneration is typically provided by means of steam extraction from the power cycle [5].…”
