Carbonyl sulfide (COS) is a pervasive and problematic sulfur compound found in various industrial gas streams, including natural gas, synthesis gas, and refinery gases. Its removal is critical for preventing catalyst poisoning, reducing equipment corrosion, and meeting stringent environmental standards. NINGBO INNO PHARMCHEM CO.,LTD. offers advanced solutions for COS removal, combining the efficacy of specialized desulfurizers with dedicated COS hydrolysts to achieve unparalleled gas purity. These chemical catalysts are engineered to address the challenges posed by organic sulfur compounds, ensuring that industrial processes operate smoothly and efficiently.

The challenge with COS lies in its relatively stable chemical structure, which can make it difficult to remove using conventional desulfurization methods alone. Our approach involves a two-step process that is highly effective. First, a robust zinc oxide desulfurizer is employed to handle general sulfide removal and to pre-treat the gas stream. This agent operates efficiently at low temperatures (100-150ºC) and significantly reduces overall sulfur content. Crucially, for tackling higher concentrations of COS, we integrate a specific COS hydrolyst. This hydrolyst converts COS into hydrogen sulfide (H2S), which is then more readily removed by the desulfurizer or other subsequent purification stages.

The synergy between the COS hydrolyst and the desulfurizer ensures a multi-barrier approach to sulfur contamination. By systematically breaking down COS and then capturing the resulting sulfides, this strategy allows for the achievement of ultra-low sulfur levels, often below 0.1 ppm. This advanced purification technique is particularly beneficial for industries such as petrochemicals, fertilizer production, and gas processing, where feed gas purity directly impacts product yield and catalyst lifespan. The ability to reduce sulfur content from 1-10 ppm to such low levels underscores the power of these integrated solutions.
