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) and VR (Vacuum Residue), and prepared the feed of RFCC (Reduced Fluid Catalytic Cracking) unit. The unit includes the following parts: â?¢ Feed Pretreating (Filter) Section â?¢ Reactor Section â?¢ Fractionator Section â?¢ Make-up Hydrogen Compression Section These compounds are easily converted to H2S. However, feed stocks containing hetero atomic aromatic molecules are more difficult to process. Desulfurization of these compounds proceeds by initial ring opening and sulfur removal followed by saturation of the resulting olefin. Thiophene is considered 15 times more difficult to process compared to diethylsulfide. The main problem in this unit is pressure drop. In this paper, reason of pressure drop and proposed solution in the fix bed reactores has been investigated.
