Abstract
Gas sweetening solutions are described that are capable of removing hydrogen sulfide from gas streams. These gas sweetening solutions increase the size of produced sulfur particles and thereby improve efficiency of their separation, while simultaneously reducing corrosive effects of the sweetening solutions. The gas sweetening solutions comprise at least one chelating agent, cationic iron and a mixture of nitrite salt and phosphate species.
