A process for recovering hydrogen during hydroprocessing, where the process includes providing a pressure increasing device to a hydroprocessing unit, wherein the pressure increasing device utilizes a high pressure stream from a separator for increasing pressure; introducing a hydrogen containing stream to the pressure increasing device, thereby increasing the pressure of the hydrogen containing stream; and routing the hydrogen containing stream from the pressure increasing device to a vapor-liquid separator. The process also includes separating the hydrogen from the hydrogen containing stream in a hydrogen purification unit to produce a recovered hydrogen stream; and then preferably using the recovered hydrogen stream from the hydrogen purification unit within the hydroprocessing unit.
