1. A method for removing a particulate matter from a multiphase stream comprising a gas, a liquid and the particulate matter, the method comprising:
a) conveying the multiphase stream to a first vessel; separating a majority of the gas from the multiphase stream and removing the separated gas from the first vessel; and collecting a slurry of the liquid and the particulate matter from the multiphase stream in the first vessel;
b) conveying the slurry to a second vessel and separating the particulate matter from the liquid by generating a pressure head of the liquid above the particulate matter to cause the particulate matter to settle in the bottom of the second vessel and compress the particulate matter to force out entrained liquid; and
c) conveying the particulate matter out of the second vessel,
wherein step a) occurs continuously, and wherein step b) is halted when step c) occurs.
