In the oil and gas sector, fractionation is a vital part of every plant. Splitters are fractionators that are used to split low-boiling-point mixed components into high-purity products. Propylene is obtained via various processes; one of them is propane dehydrogenation, where splitters are often used. Propane feedstock is fed to the propane dehydrogenation plant (PDH), which includes a reaction section to partially convert propane into propylene and secondary products. The PDH unit also contains equipment for the extraction of the propane/propylene mixture from other secondary products. The extracted propane/propylene mixture is fed to the C3 splitter, where the propane and propylene are s
