Abstract
The unit of RCD (Reduced Crude Desulfurization) was applied for decreasing of Sulfur, CCR (coradson carbon residue), metals of heavy feeds AR (Atmospheric Residue), VR (Vacuum Residue), and also prepared the feed of RFCC (Reduced Fluid Catalytic Cracking) unit. The unit includes the following parts: Feed pretreating (Filter) Section, Reactor Section, Fractionator Section, make-up Hydrogen Compression Section. These compounds were easily converted to H2S, however feedstocks containing heteroatomic aromatic molecules were processed difficulty. Desulfurization of these compounds was preceded by initial ring opening and sulfur removal followed by saturation of the resulting olefin. Thiophene was processed 15 times more difficult compare to diethylsulfide. There is used Fix bed reactor type One of the main problem in such unit is differential of pressure of reactors. This paper discuss about "How we could prevent dp in the reactors in real operation".
