Gas treatment is a solvent-based technology to capture acid gases by absorption followed by regeneration. Optimized solvent chemistry is critical to manage amine degradation and operation in the presence of heavy hydrocarbons, heat stable salts, and oxygen. Innovations in mass and heat transfer improve overall energy efficiency.
Process Description
Gas containing H2S and CO2 is contacted in an absorption tower with a solvent, which has a preferential affinity for the acid gas treatment. This allows the feed gas to be stripped out of these components, which end up in the solvent. The purified gas leaves at the top of the absorber tower. The “rich” solvent is then heated through the “lean-rich” exchanger, and sent to the stripper column where it is thermally stripped. The “lean” solvent is re-circulated, cooled through the “lean rich exchanger” and then through fin-fan or other coolers prior to entering the amine absorber.
The solvent is chosen to have a preference for H2S over CO2, thereby enabling the enrichment of one component over the other. There are many nuances to the design and operation of a reliable acid gas removal and enrichment process. This is driven by the aerosolized contaminants in the feed stream, complexity of the absorption, the liquid phase reactions, heat stable salt formation, corrosion reaction. Design and operations experience is critical for a robust and reliable system.
Acid gas treatment and sulfur innovation portfolio is centered around conveying eco-accommodating answers for corrosive gas expulsion, lack of hydration, mercury evacuation, fluids recuperation and sulfur recuperation from an assortment of procedure gas streams to meet certain client needs. These advancements are conveyed in an assortment of ways incorporating permit with an essential designing bundle or with an Engineering, Procurement and Construction administration (EPCm) bundle. The expansive arrangement of items and broad experience empowers customers to flawlessly incorporate our procedures crosswise over business lines.
