Exergy study of amine regeneration unit for diethanolamine used in refining gas sweetening: A real start-up plant

Alexandria Engineering Journal, 2022
Diethanolamine (DEA) solutions are used in refineries to sweeten gas. DEA is responsible for absorbing H2S from sour gas. In an Amine Regeneration Unit (ARU), the rich amine with H2S is regenerated. A refining column in the Middle East started commercial

Assessment of Gibbs Free Energy Calculation in PI‐Controlled Heating

Chemie Ingenieur Technik, EarlyView.
For description and control of chemical processes in lab or industry thermodynamic variable Gibbs free energy provides opportunity to compare and interpret phenomena, even on a quantitative level. In a case study for PI‐controlled heating, impacts on its limits from control delay until parameter quantization are highlighted and assessed.
