Acid Gas Enrichment

Sulfur Recovery Unit (SRU) performance is sometimes hampered by feeds of such low quality (low sulfur content) that a special thermal reactor configuration is needed to process the gas. These special arrangements usually have higher CAPEX and OPEX associated with them and therefore lower profitability.  In such cases, Acid Gas Enrichment (AGE) can be very effectively used to upgrade feed gas from even 10% sulfur to a very high sulfur content, avoiding any special steps or equipment to enable processing and allowing for a much smaller SRU to be used because the parasitic inert gas load is greatly reduced.

ProTreat® simulation can be reliably and robustly carried out to determine the optimal processing conditions and the best process configuration. You can even assess the efficacy of HIGHSULF™ technology to achieve an ultra-rich feed gas. Convergence is very rapid and because everything is mass-transfer and reaction-kinetics rate-based, a system in which most of the gas is actually wet acid gas and therefore almost completely soluble in the amine solvent (with little or no inerts present at all), it presents absolutely no challenge to ProTreat’s algorithms. ProTreat can help you design an AGE unit capable of rejecting 95% of the CO₂ and retaining 99.9% of the H₂S to produce a phenomenally enriched SRU feed with minimal sulphur leakage to the environment.
