GN will show a 14 inch bowl decanter centrifuga at OTC, after the show, it will be sold out to South America. To length the service life of decanter centrifuga in drilling fluids separation, proper installation & maintenance is necessary.

At present, GN provide the decanter centrifuga below:

decanter centrifuga

decanter centrifuga

By bowl speed: high speed decanter centrifuga, middle speed decanter centrifuga y VFD decanter centrifuga

By bowl diameter: 14inch bowl, 8.7 inch bowl, 18inch bowl y 22 inch bowl decanter centrifuga

By speed adjustable o no: fixed speed decanter centrifuga y VFD decanter centrifuga

By screw propeller protection method: coating with tungsten alloy o welding with tungsten carbide tiles

Totally we have GNLW223, GNLW363, GNLW452, GNLW453, GNLW553 series centrifuga. The main components of GN decanter centrifuga are as below:

1 bowl drive motor 2 screw conveyor drive motor 3 gear box 4 screw conveyor 5 bowl 6 hydraulic coupling 7 skid 8 vibration isolator 9 collection box 10 solids discharge chute 11 feed tube 12 fluids discharge churt 13support bracket

Among them, gear box, feed tube and screw conveyor is the most wearable parts, you need regular maintenance on them.

GN produce Vacu-FLO degasser with 1000gpm, 1200gpm, 1320gpm, 1584gpm degassing rate.

GN ZCQ series Vacu-FLO degasser v.s.Swaco horizontal degasser

Swaco horizontal degasser and vertical degasser are all different with GN vacuum degasser both in structure and working principle.

Working principle of Swaco horizontal degasser

The return-flow, gas-cut mud is drawn into the tank through a vacuum created by the discharge jet and pump. The mud is then dispersed in a thin layer over a two-tier, baffle-plate system where the entrained gas, including H2S and corrosive oxygen, is recovered by the vacuum pump. The freed gas is then discharged at a safe distance from the drilling operation while the restored mud is returned to the active mud system.

Working principle of GN

Vacu-FLO degasser

The vacuum degasser uses the suction of the vacuum pump to establish an under balanced pressure area in the vacuum cylinder and causes the drilling fluid into the hollow shaft of the rotator through suction pipe under the atmosphere pressure, and then lets the fluid spray to the walls of the cylinder from the windows on the hollow shaft, now the gas bubble cut in the mud may break and run off in the function of vacuum pump suction to a safe area due to the fluid collision and bubble separator. However, the mud will enter the drainage cavity forced by its self-weight and pass the rotator and discharge off the cylinder. In addition, drilling mud can enter the pump cylinder only through the suction pipe, and can’t be sucked in through the discharge pipe because the vacuum pump and the master motor are started simultaneously and the rotator connected to the motor will revolve at a high speed.

Features of GN vacuum degasser

l)  Skid-mounted design simplifies spotting and installation

2)Small footprint-69x34in.(1750x860mm)

3) Totally self-contained

4)  Corrosion-resistant, epoxy coated inside and out to ensure long life and minimum maintenance

5) More leaf surface area- The greater the effective surface area, the more efficiently gas is separated from the mud.

6) GN particular design- provide higher fluid impact and greater turbulence for faster gas removal. you do not need extra feeding pump, it saves a lot of money and place for clients.
