Two-Column Sour Water Stripping without Sending Ammonia to The Sulfur Recovery Unit [PDF]

Journal of Petroleum Science and Technology, 2020
In conventional sour water stripping (SWS) in petroleum refineries, H2S and NH3 of the sour water are separated simultaneously at the top of a tray column by sending sour gases to the sulfur recovery unit (SRU).

Emission Minimization of a Two-Stage Sour Water Stripping Unit Using Surrogate Models for Improving Heat Duty Control

Journal of Sustainable Development of Energy, Water and Environment Systems, 2019
Sour water are aqueous waste streams from oil refining operations, heavily contaminated with hydrogen sulfide and ammonia, which need to be stripped before reuse or disposal, avoiding damages to process and environment.

Optimization of Sour Water Stripping Unit Using Artificial Neural Network–Particle Swarm Optimization Algorithm

Processes, 2022
Sour water stripping can treat the sour water produced by crude oil processing, which has the effect of environmental protection, energy saving and emission reduction. This paper aims to reduce energy consumption of the unit by strengthening process parameter optimization. Firstly, the basic model is established by utilizing Aspen Plus, and the optimal

Absorber design in sour natural gas treatment plants: Impact of process variables on operation and economics = Absorberentwurf für Anlagen zur Behandlung von sauren Erdgasen: Einfluss Prozessparameter auf Betriebsführung und Prozesswirtschaftlichkeit [PDF]

, 1985
Two models of absorber have been developed which describe the absorption of H2S and CO2 from natural gases by aqueous di-isopropanolamine (DIPA) or methyl-di-ethanolamine (MDEA) solutions. In these models mass transfer, reaction and equilibrium processes

Large scale optimization of a sour water stripping plant using surrogate models [PDF]

Computers & Chemical Engineering, 2016
In this work, we propose a new methodology for the large scale optimization and process integration of complex chemical processes that have been simulated using modular chemical process simulators. Units with significant numerical noise or large CPU times are substituted by surrogate models based on Kriging interpolation.
