Abstract

A system for processing drilling mud, the system including a primary separation tank having an inlet for receiving drilling waste and an outlet in fluid communication with a feed line, and an injection pump in fluid communication with a polymer tank and the feed line. The system also includes a clarifying tank in fluid communication with the feed line and a first collection tank, wherein effluent from the clarifying tank is discharged into the first collection tank, and a centrifuge in fluid communication with the clarifying tank and a second collection tank, wherein effluent from the centrifuge is discharged into the second collection tank.

First claim

What is claimed is:

1. A system comprising:
a primary separation tank having an inlet for receiving drilling waste and an outlet;
an injection pump in fluid communication with the outlet of the primary separation tank and a polymer tank;
a clarifying tank having a venturi zone formed adjacent to an outlet of a constricted pipe coupled to a first end of an internal pipe, wherein the internal pipe has a total length defined between the first end of the internal pipe and a second…
