Claus Process
The Claus Process is a standard method used in oil refineries and chemical plants to handle and clean up sulfur-containing gases. Think of it as a cleaning system that removes harmful sulfur from natural gas and oil products, turning it into useful sulfur that can be sold. This process is important because it helps plants meet environmental regulations and create a marketable product at the same time. When you see this term in a resume, it usually means the person has experience working with environmental protection systems in refineries or chemical plants.
