A method of discharging particulate solids from a solid-liquid-gas mixture discharged from a high pressure vessel having an effluent stream comprises discharging the mixture from the vessel at a low pressure differential of no more than 150 p.s.i. to a fluid-solid separation zone, continually venting liquidgas substantially free from particulate solids from the fluid-solid separation zone to a point in the effluent stream until the venting of the liquid gas is decreased by accumulation of particulate solids in the fluid-solid separation zone, terminating both the discharge of the solid-liquid-gas mixture from the high pressure vessel and the venting of the liquid-gas to the effluent stream and subsequently recovering particulate solids from the fluid-solid separation zone. The invention is particularly described with reference to a plant for hydrocracking hydrocarbons catalytically. Additionally the plant may embrace a fractionating device for dealing with the liquid phase.
