Recent progress in electrochemical decomposition of hydrogen sulfide for sulfur recovery and hydrogen production. [PDF]

open access: yesFront Chem
Hydrogen sulfide (H2S) generated by industrial processes (such as petroleum refining, natural gas purification, and coal processing) is a highly toxic and corrosive gas, which is detrimental to human health and environment. Electrocatalytic decomposition

Design, optimization and controllability analysis of an improved sulfur recovery unit based on SuperClaus process. [PDF]

open access: yesSci Rep
To meet stricter environmental regulations, the SuperClaus process has been proposed to enhance sulfur recovery in Claus sulfur recovery units (SRUs). SuperClaus modifies the traditional Claus process by adding a catalytic bed for direct hydrogen sulfide

Sustainable Approach for Recovery of Sulfur from Phophogypsum [PDF]

open access: yesACS Omega, 2020
Phosphogypsum releases have a detrimental effect on flora and fauna and also cause economic loss due to the loss of sulfur. This study contributes to solving this problem using a process that consists of the valorization of this byproduct. A new sustainable method that consists of using sulfuric acid is proposed to process the Algerian phosphogypsum to
