Many refineries try to remove H2S from cracked streams used in blending fuels. It was found that the three adsorbents are capable of effectively removing sulfur compounds at different feed sulfur concentrations. This allows the used or spent media to be replaced in half the time it takes to replace other solid-based scavenger systems. Pumps are powered by air pressure or nitrogen, and system utilizes a closed loop calibrator to eliminate concerns with exposer of mercaptan to the atmosphere. Product mercaptan levels of less than 1 part per million (ppm) by weight (wppm) may be achieved. As the caustic solution (and often a catalyst) mixes with the hydrocarbon feed it either extracts or sweetens mercaptans, depending on the process used. For liquid hydrocarbon streams (LPG) a similar strategy is usually applied, with an amine extraction step to remove the H2S followed by a mercaptan extraction system based on the Merox process. Merox is an acronym for mercaptan oxidation. Unfortunately where we're located there isn't a mercaptan-free LPG supply. Determination of Carbon Dioxide, Ethane And Nitrogen in Natural Gas by Gas C.
