Optimum process for selective hydrogenation/hydro-isomerization, aromatic saturation, gasoline, kerosene and diesel/distillate desulfurization (HDS). RHT-hydrogenationSM, RHT-HDSSM
Optimum process for selective hydrogenation/hydro-isomerization, aromatic saturation, gasoline, kerosene and diesel/distillate desulfurization (HDS). RHT-hydrogenationSM, RHT-HDSSM
A process for selective hydrogenation of C3/C4/C5/C6/C7 and LCN, hydro-isomerization of olefins, benzene saturation and hydrodesulfurization of Gasoline, Kerosene and Diesel together with aromatic saturation of LCO is being provided so as to provide optimum technology at low cost with unique configuration. The technology is user friendly and uses conventional catalyst. These configurations cover both the options of installing the bulk catalyst in the distillation column with chimneys trays, hence essentially all the reaction takes place in the liquid phase in single or multiple beds or with fixed bed down flow or up flow reactor configuration. The configurations shown in the figures depicts that the fixed bed reactors are integrated with the Distillation Column and this art helps in lowering the Capital costs and the reactors are operating in single phase or two-phase conditions. The art is applicable to MAPD, vinyl acetylene, C3, C4, C5, C6, C7 mixed hydrocarbon stream, and LCN diolefin selective hydrogenation. It includes the process for hydro-isomerization of Butene-2 to Butene-1, or visa versa, removal of Isobutylene and Isobutane by distillation after hydro isomerization, benzene hydrogenation to Cyclohexane, hydrodesulfurization of FCC gasoline, coker gasoline or any other Naphtha stream together with hydrodesulfurization of Diesel/Kerosene from any of the refinery units.
