ABSTRACT:
A process to separate solids from a solids laden gaseous flow containing more than 100 mg/Nm3solids by separating solids from the gaseous flow using a gas-solids separator resulting in a gaseous flow containing less than 50 mg/Nm3solids and an underflow having the separated solids and part of the gaseous flow as fed to the gas-solids separator; separating part of the solids from the underflow in a cyclone wherein solids and a gaseous flow containing still some solids are obtained; contacting the gaseous flow obtained with water to separate the solids and obtain a gaseous flow containing between 0 and 50 mg/Nm3solids; and combining the gaseous flows which are poor in solids.
