A quenching vessel being, in use, vertically elongated and provided with an inlet for gas at its upper end, an outlet for cooled gas at its lower end defining a pathway for a gas flow directed downwardly, the vessel being provided at its upper end with a first internal tubular wall part which wall part has an opening fluidly connected to the inlet for gas and wherein the tubular wall part is connected at its lower end with a divergent conical part having walls which are inclined outwardly in the direction of the pathway for gas, wherein an arrangement of more than one nozzle for atomisation and spraying a liquid quench medium in a downward direction into the pathway for the gas flow are present in the space enclosed by the divergent conical part.

A quenching vessel being, in use, vertically elongated and provided with an inlet for gas at its upper end, an outlet for cooled gas at its lower end defining a pathway for a gas flow directed downwardly, the vessel being provided at its upper end with a first internal tubular wall part which wall part has an opening fluidly connected to the inlet for gas and wherein the tubular wall part is connected at its lower end with a divergent conical part having walls which are inclined outwardly in the direction of the pathway for gas, wherein an arrangement of more than one nozzle for atomisation and spraying a liquid quench medium in a downward direction into the pathway for the gas flow is present in the space enclosed by the divergent conical part, wherein the lower end of the vessel has a tapered end terminating in a central opening as the outlet for cooled gas.
A process for quenching a synthesis gas having a temperature of between 500 and 900° C. and a pressure of between 1 and 10 MPa to a temperature of between 200 and 600° C. in a vertical vessel, which vessel is vertically elongated and provided with an inlet for gas at its upper end, an outlet for cooled gas at its lower end defining a pathway for a gas flow directed downwardly, the vessel being provided at its upper end with a first internal tubular wall part which wall part has an opening fluidly connected to the inlet for gas and wherein the tubular wall part is connected at its lower end with a divergent conical part having walls which are inclined outwardly in the direction of the pathway for gas, wherein an arrangement of more than one nozzle for atomisation and spraying a liquid quench medium in a downward direction into the pathway for the gas flow is present in the space enclosed by the divergent conical part, wherein said gas passes through the vessel in a downward direction and wherein the vessel has a divergent conical part having walls which are inclined outwardly in the direction of the gas and wherein to the gas as it passes the divergent conical part a mist of liquid water droplets is injected in a downward direction, wherein the amount of injected water is selected such that the synthesis gas leaving the vessel comprises from 40 to 60 vol. % water.
