The Hot H₂ stripper takes the heavier liquid from the cyclonic separator and uses hydrogen to enhance separation efficiency. The stripping column is designed to separate and upgrade the preheated hydrocarbon stream using hot hydrogen gas instead of steam, injected at the bottom of the column as the stripping medium, which improves separation while also facilitating some degree of hydrotreating or saturation by reacting with olefins and sulfur compounds in the feed. The overhead stream becomes rich in light hydrocarbons (e.g., LPG, naphtha) and H₂S, while the bottom stream contains heavier, stabilized components.
