Latest technological advances and insights into capture and removal of hydrogen sulfide: a critical review

“…Aside from this, the deployment of metal oxide adsorbents in industrial applications for H 2 S capture such as iron oxide (FeO) adsorbents and mixed metal oxide-based adsorbents is getting recognition due to their capability of reducing H 2 S concentration to 10 ppm while avoiding heat loss at high temperature. 185,186 FeO-based adsorbents such as SULFATREAT and SELECT FAMILY were developed by Schlumberger, 187 while mixed-metal oxide adsorbents such as CuO/ZnO-based adsorbents, i.e., PURISTAR® and alumina-based adsorbents, i.e., Selexsorb® were developed by BASF. H 2 S adsorption on a metal oxide reaches 95% even at high temperature and resulted in the formation of a solid or liquid phase containing sulfur and an adsorbent metal.…”

“…There are a few advantages of the adsorption process such as low cost, energy-efficiency, easy operation and simple design besides having a high temperature variation. 185,186,188 However, there are various drawbacks associated with the adsorption process such as high-pressure steam requirement to desorb high molecular weight pollutants and a gas stream pre-lter to prevent any particles from clogging the adsorbent bed. 238 In general, the adsorption process requires high temperature and pressure to operate optimally.…”
