TAILIEUCHUNG - WSA technology turns your off-gas into money

When oil and gas is being processed the generated H2 S needs to be removed and converted, due to environmental legislation. Traditionally, acid gas is converted in a Claus plant forming elemental sulfur; however this is an ineffi cient approach both out of an economic and operational context. | PETROLEUM PROCESSING WSA TECHNOLOGY TURNS YOUR OFF-GAS INTO MONEY Amrul Atiqi Haldor Tops0e A S Email aasa@ Summary When oil and gas is being processed the generated H2S needs to be removed and converted due to environmental legislation. Traditionally acid gas is converted in a Claus plant forming elemental sulfur however this is an inefficient approach both out of an economic and operational context. Today the most optimal solution for treating acid gases from Acid Gas Removal Units AGRUs is with the innovative WSA Wet gas sulfuric acid technology that converts acid gases into sulfuric acid. The WSA technology is a superior solution for treatment and conversion of acid gases and this paper will describe both the potential economic benefits and the unique process principles of the technology. Key words H2S SO2 WSA Claus emission refineries gas processing sulfur off-gas steam sulfuric acid environmental flue gas acid gas desulfurisation sour gas SOx NOx. 1. Introduction The reason why the WSA process today is the most optimal technology for converting acid gases is due to the following facts A Topsoe WSA plant has lower investment costs than a plant producing elemental sulfur with the same emission requirements. A Topsoe WSA plant can meet the most stringent environmental regulations even without tail gas treatment. Neither chemicals nor other additives are consumed in the process and there will not be any solid or liquid effluents requiring additional treatment. A Topsoe WSA plant is much simpler than a plant producing elemental sulfur. This simplicity of the process also makes it easy to operate and thereby contributes to a higher availability and less unintended shutdowns. When producing sulfuric acid a lot more energy is released than when producing elemental sulfur. The steam production is as much as 4 times higher when producing sulfuric acid as compared to producing sulfur. Why not utilise this energy yourself rather than exporting it with the sulfur
