Abstract
A two-stage liquid distribution device for use within an internal region of a mass transfer column to distribute liquid to an underlying mass transfer bed. The two-stage liquid distribution device includes a lower distributor with a lower parting box and lower troughs and an upper distributor with an upper parting box and upper troughs. The lower and upper parting boxes and troughs are enclosed to allow a liquid head in a lower downpipe section and an upper downpipe section that feed liquid to the lower distributor and the upper distributor to cause pressurization of liquid within the lower and upper parting boxes and troughs. The pressurization makes the lower and upper distributors less susceptible to rocking motion of the mass transfer column and reduces any maldistribution of liquid discharged from the lower and upper troughs to the mass transfer bed.
