GN Solids Control (with a separate US brand and company, GN Solids America) is a leading manufacturer for drilling waste treatment system. GN brand drilling waste management equipment and system are sold to over 60 countries and regions worldwide, including USA, Canada, Argentina, Brazil, Chill, Egypt, Algeria, Libya, Saudi Arabic, Iran, Iraq, Nigeria, Turkey, India, Indonesia, etc…

GN drilling waste treatment system are suitable to treat the drilling cuttings with rigs or in the waste mud pit.

Below is a general idea of the treatment for oily waste from drilling rigs or from oil refine industry.

Step 1: Oily sludge mixing tank, 1 ea

The oil waste from mud pit goes to the tank and it is mixed with chemicals. There is mud agitators equipped to the tank to stirring the oil waste with chemicals. The chemical is used to make the oil comes out from the waste. The oil, waste and solids are easy to layering after settle down. Solids from the tank goes to shaker for treatment.Liquid goes to oil water separator.

Step 2: High G drying shale shaker 1 ea and Decanter centrifuge 1 ea. This step is for mechanical separation.

A 4-panel high G drying shaker is used in this step. The shaker is used to remove coarse particles from the oil waste. The liquid will be further separated by the 1# decanter centrifuge. Solids phase from shale shaker goes to TDU for further dry. Liquid phase from 1# decanter centrifuge goes to dewatering unit and then separated by high speed centrifuge.

Step 3: Dewatering unit and a high speed Decanter centrifuge 2# for remove the fine solids

Flocculants from dewatering unit is mixed with the liquid from 1# decanter centrifuge. And then the mixture of chemical and liquid goes to centrifuge 2# for treatment. Solids from 2# decanter centrifuge goes to TDU. The Fluids from 2# centrifuge is mixture of oil, water and small content of ultra fine solids, they can go to oil water separator.
