<p>The invention relates to a method for hydrotreating hydrocarbons, consisting a) in mixing hydrocarbons and hydrogen at a required ratio by supplying the two flows to a jet pump, the hydrocarbons being supplied to the initiating part of the pump at a pressure providing the required production volume flow rate and the mixture pressure in a reaction area, b) in dividing the mixture flow coming out from a reactor into two flows, i.e. liquid and gas flows, c) in separating the gas flow by gradually reducing the temperature thereof, thereby removing components having the highest critical temperature (Tcr) therefrom at each stage, the thus cleaned hydrogen being fed to the jet pump input, thereby closing the recirculation circuit thereof, and d) in removing liquefied gases from the liquid flow by gradually restricting the flow pressure, thereby converting each individual component into a gaseous phase. Said method makes it possible to lessen a capital-output ratio, energy consumption and to reduce the parasitic invasion of gases in liquid.</p> |
