Acid gas purification by chemical absorption

As to the chemical absorption of acidic gas with MEA, MDEA and PZ we observed different results from commercial simulation packages. The goal is to properly “modify” a commercial simulation software in order to obtain reliable results from an AGR simulation.

GASP research is also focused on the study of innovative solvents for acid gas removal.

Different techniques for acid gas removal

As examples of other acid gas removal techniques we report two cases. The first one regards the upgrading of sewage sludge-derived biogas from the King County South Treatment Plant (Renton, Washington) by water washing at high pressure.

Downstream separations in biotechnology

The continued development of bioeconomy is expected to deeply transform several segments of the chemical industry, from bulk to fine chemistry. In this field, in which the separation costs come to exceed 70% of the total production costs, the GASP group has recently oriented his research activity towards two strategic areas.

Solid-Vapor-Liquid Equilibrium

The use of low-temperature processes has recently received great attention as an effective method for removing CO2 from flue gases or from natural gas to produce pipeline quality natural gas.

Hydrates formation prediction

Gas hydrates are solid compounds that resemble snow or ice in appearance but are formed in the presence of water at high pressures and at temperatures above the ice point.
