Abstract
A method and apparatus for removing low micron solids from a mixture of recovered oil based drilling fluid and low micron solids and diluent. A gas tight clarifier device that is designed and constructed for this purpose in a gas-tight manor so to ensure vapour cannot escape the separation process, and foreign oxygen cannot enter the process under normal operating conditions.
