Process flow diagram of the residue hydrotreating unit. A typical Process Flow Diagram (or PFD) explains the process for pygas processing or pygas hydrotreating. Hydrotreating is a process that utilizes high-pressure hydrogen to remove oxygen from the fuel, which is then converted into water. All of these factors should be carefully considered during the front-end process design. A block flow diagram of the SRC-II process is shown in Fig. Different feedstocks can be treated such as: straight run, condensate and more refractory ones such as cracked naphtha (coker, Vacuum Bottom, cracked catalytic naphtha). Pyrolosis gasoline or pygas (C5+ cut) is a liquid by-product derived from steam cracking of various hydrocarbon feedstocks in olefin plants. 1 A typical diesel hydrotreating process flow sheet (Meyers, 1997) . The emphasis is typically on the removal of contaminants such as sulfur and nitrogen to avoid poisoning downstream catalysts. • Up to 89% carbon yield of hydrotreated oil was produced with an oxygen content < 0.
