Month: October 2018

This week GN solids control shipped one unit of 4 phase cleaning HDD mud recycling system to Sinopec. Normally the HDD mud recycling system is with 2 phase cleaning or 3 phase cleaning, this system is customized for 4 phase cleaning.
The system is consist of the parts below:

1) 1 unit of linear motion shale shaker GNZS703F-DZ installed with 3pcs of composite material shaker screens for free, 2 units of Italy Oil brand vibration motors with max G force 7.5G, which is adjustable.
2) 1 unit of linear motion mud cleaner GNZJ703F-1S8N with 500gpm treating capacity with 2 units of centrifugal pumps as feeding pump of desander cone, desilter cone. The underflow shale shaker model is same with the shale shaker GNZS703F, same dimension shaker screens.

3) 1 unit of VFD decanter centrifuge GNLW363C-VFD, with non explosion proof VFD control panel to adjust the frequency to adjust the rotary speed of the centrifuge, it can control the flow rate by adjust the speed. Vertical submersible slurry pump is installed on the mud tank as feeding pump of decanter centrifuge. One set of screw conveyor is installed to transfer the solids from the centrifuge discharge port to waste container. It is an automatically operation system and no need worker to watch for it time and time.
4) 2 mud tanks with same dimension for convenient shipment, the shale shaker and mud cleaner are equipped in a same dimension frame, which can be put on the same trailer for movement.

This week one unit of containerized 15 m3/h oil sludge separation system to Europe client.
The configuration consists of 5 modulars:

1) Pre- mixing tank: the pre mixing tank is necessary, it will influence the result of the equipments next, like shale shaker tank, decanter centrifuge tank, disc centrifuge tank.
2) Shaker tank: the shale shaker with mud agitator installed on top of the mud tank, heating lines around the tank to increase the oil sludge flowability and increase the decanter centrifuge separation performance.

3) 2 phase separation tank : the 22 inch decanter centrifuge installed on top of the tank, the screw pump installed on the same skid, and the screw conveyor collect the solids from the solids discharge port of the decanter centrifuge and transfer outside the container.

4) 3 phase separation skid ：the disc centrifuge installed on the skid, the fluids discharged from the centrifuge fluids port flow to disc centrifuge, the clean oil and water will be pumped to separate oil tank and water tank.
5) Chemical dosing system: the chemical dosing system with 3 mixing tank chemical dosing system, and the coagulation system, each tank with chemical dosing pumps.
The oil sludge separation system is used in cold area, so all of the equipments are installed inside the 40ft container to keep it warm. We also consider the operation convenience for the user.
This is the repeat order from the same client, they bought one unit of 1 m3/h oil sludge separation system several month ago, and satisfied with the result.
Except for oil sludge separation system, GN solids control also provide good quality solids control system, drilling waste management system, we will send the question list to the client to know the project information firstly, then we will design customized system for our clients.

2 sets of oil sludge separation system are finished production in GN solds control, one system with grey silver color is 2 m3/h oil sludge treatment system , the other one is 15 m3/h oil sludge treatment system, which will be released next week.

The 2 m3/h oil sludge treatment system is a trial order for the client, if it works well, the client will repeat order for a bigger one, GN standard and customized oil sludge separation system has been proved the performance.

The technical configuration is as below:
1) Pre-mixing tank
Premixing tank is the necessary part of the oil sludge separation system, the sludge vacuum pump transfer the oil sludge from the waste pit to pre mixing tank for heating, agitating, chemical jetting, without proper premixing, the fluids flowrability will be increased, the separation result will be better.

2) Classification modular, the oil sludge from pre mixing tank will be transferred to V tank bottom which with screw conveyor on the bottom, after classification, the top layer will flow to disc centrifuge, the bottom layer will be washed, chemical jetting and transferred to solids control manular.

3) Solids control modular: it consists of shale shaker and 2 phase decanter centrifuge for liquid solids separation. The clean fluids separated from 2 phase decanter centrifuge will also flow to disc centrifuge modular. Both of the tanks with heating line around for heating the oil sludge and increase the separation efficiency.

4) 3 phase separation skid: this is a back up skid, including gravity type oil water separator, once the disc centrifuge failed to work or during maintenance, the 3 phase separation skid will be work as back up.
GN solids control can design and produce customized oil sludge separation system as per client’s different requirement. Pls contact with GN team freely.
