During oil base mud and drill cuttings treatment process, high speed decanter centrifuges should be used after vertical cuttings dryer to reduce the mud weight, and make the drilling mud satisfied for reuse.
Recently, GN Solids Control made a small decanter centrifuge test unit for a mud services company to offshore drilling mud treatment. The centrifuge model is GNLW224EP-VFD. It is located on a telescopic skid. The skid is capacity to put a cutting skips under it for holding the recovered drilling mud.
GN Solids Control is capable to make various sizes of decanter centrifuge to meet different job sites request. Below are some high speed decanter centrifuge models GN Solids Control can make:
1) 9 inch. It is the smallest size decanter centrifuge mainly used for waste water and slurry treatment. Per bowl diameter and length ratio, GN offers GNLW223 and GNLW224 series. With fixed speed and VFD control for optional.
2) 14 inch. It is the most popular size for oil gas drilling to treat the drilling mud and drilling cuttings. It is also widely used for waste water and oily slurry treatment and dewatering treatment. GN offer high speed and lower 14 inch decanter centrifuge per clients’ request. And the centrifuge can be fixed speed control, VFD control or FHD control to suit for various applications. The major model is GNLW363 series with different speed and control panel designs.
3) 18 inch. It is a kind of big bowl centrifuge for fine solids separation and waste treatment. It is also popular used in oil and gas drilling and other kinds of drilling mud processing. It must be VFD control or FHD control for 18 inch big bowl centrifuge as the big motor power. Per bowl diameter and length ratio, GN offers GNLW453 and GNLW454 series.
4) 22 inch. It is a kind of big bowl centrifuge for fine solids separation and waste treatment. It is also popular used in oil and gas drilling and other kinds of drilling mud processing. It must be VFD control for 22 inch big bowl centrifuge as the big motor power. Per bowl diameter and length ratio, GN offers GNLW553 and GNLW554 series.
5) 30 inch. The centrifuge model is GNLW764 series. It is the largest side decanter centrifuge made by GN Solids Control. It is mainly used for slurry treatment for mining, construction waste water, or other industry waste water treatment applications. GN Solids Control can make automatic lubricating system for the largest big bowl centrifuge to user friendly.
