In April, a full set of drilling cuttings washing system is ready for commissioning for a China client at client’s job site. The drilling cuttings washing system is used to wash and separate oil base drilling cuttings and oil sludge generated from oil and gas drilling, and refinery.
There are 7 treatment modular in this drill cuttings treatment washing system:
1.Pre-treatment: A set of coarse shale shaker is used in this modular for crushing the big rocks and for pre-seperation. It is the pre-treatment before all separation steps.
2.Screening separation modular. There is a high G drying shale shaker used in this step to remove the big size particles.
3.Washing modular with static mixing for mixing and preparing solids and liquid mixture. After that, the liquid mixture can be separated by next step separation equipment.
4.Liquid and Solids separation modular with decanter centrifuge for 2-phase separation. It is the 1st time liquid and solids separation.
5.The 2nd time washing modular with dewatering treatment to remove the fine solids in the liquid.
6.The 2nd time 2-phase decanter centrifuge separation unit for ultra fine solids separation.
7.The liquid recovery modular.
It is a a full function oil based drilling cuttings washing and separation system with a full set of separation and treatment equipment. Below list is the major treatment equipment used in this oil based drill cuttings washing system:
1.A Drum shale shaker is used in the pre-treatment unit to crush the big rocks and remove it.
2.A high G drying shale shaker is used in the screening separation modular to remove the big size particles. It is the most hot sale shaker model GNZS594F which is widely used in oil and gas drilling solids control systems.
3.2 sets of static mixing unit are used in the 2 stage washing modular.
4.A inclined plate clarify is used for soil settle down in the oily liquid, which is discharged from decanter centrifuges.
5.Screw conveyor and belt drive conveyor are used in the system to feed for shaker and for solids discharge from decanter centrifuges and shale shakers.
