There is a cleaning Tank for GN500 GPM mud recycling system for Saudi Arabia HDD rig, the tank is divided into 3 compartment, 1# Shaker compartment, 2# De-sander compartment, 3# Mixing compartment.
Detailed process features of GN500 GPM mud recycling system for Saudi Arabia HDD rig
1) Continues feeding of dirty slurry from mud pit to Shale Shaker.
The GN100YZ100A-30 Submersible slurry pump feed slurry from mud pit to GNZS703E Shale Shaker at capacity of 528 GPM.Slurry pump is made from Cr26 Abrasion resistant Alloy which allow users to pump high solids content fluids.
2) Pre-screening of the returned mud using GNZS703E Shale Shaker for the GN500 GPM mud recycling system for Saudi Arabia HDD rig.
This shaker can handle a throughput of more than 528 USgpm and is designed to remove particles down to 250 microns(60mesh) @ 7G force linear motion GNZS703E Shale Shaker with big screen area (2.63 ㎡)
3) Secondary and third cleaning of the returned mud using a GNZJ703E (10″×1 + 4″ × 8) Mud Cleaner.
1# GNSB5×4A-13J Centrifugal pump feed mud from 1# Shaker compartment to feed 10″×1 de-sander cones, where the particles larger than 50 microns are separated out by centrifugal force from desander cone nipple, and get down to GNZJ703E mud cleaner bottom shaker with a finer screen (150/200mesh) which again produces a virtually dry product. Major fluids with particle size less then 50microns goes to 2# De-sander compartment. This is the 2nd phase solids control of the GN500 GPM mud recycling system for Saudi Arabia HDD rig.
2# GNSB5×4A-13J Centrifugal pump suck mud from 2# desander compartment and feed to 4″x8 desilter cones. Where the particles larger then 16microns are separated out by centrifugal force from desilter cone nipple, and get down to GNZJ703E mud cleaner bottom shaker with a finer screen, which again produces a virtually dry product. Major fluids with particle size less than 16 microns goes to 3# Mixing compartment. This is the 3rd phase solids control of the GN500 GPM mud recycling system for Saudi Arabia HDD rig.
4) Integral mixing system using GNSLS35A-300 Jet Mud mixer for GN500 GPM mud recycling system for Saudi Arabia HDD rig.
This GN500 GPM mud recycling system for Saudi Arabia HDD rig allows fresh mud to be prepared very rapidly from bentonite powder. One of the 2 pumps on tank end is dedicated to this function allowing continuous mixing or recirculation as required.
5) Integral charge pumps to supply clean mud back to the drilling rig.
The mixing pump above is a dual function pump, on mixing pump outlet with a T pipe can be controlled by a valve to provide a continuous supply of clean mud from 3# mixing compartment under pressure to the high pressure mud pump, avoiding problems of starvation and cavitations which can rapidly cause damage.
