Mud Solids Control Equipment

GN Solids Control is the first China drilling waste management equipment company who can offer total solution  equipment for drilling waste management Service Company.

Regarding Oil based mud drilling cuttings, the total solution of drilling waste management including below steps:

Step 1: Vertical cuttings dryer. Use this VG dryer to treat the drilling cuttings, recover the valuable oil based mud. The OOC after treatment can be 3%-5%.

Step 2: Thermal Desorption Unit. After VG dryer, the solids can go to TDU for non-hazardous final treatment. After TDU, the water, oil and solids can be separated in accepted degree which comply with most of country’s government policy on environmental protection

Step 3: Decanter Centrifuge. After VG dryer, the liquid part (drilling fluids) can go to centrifuge to remove the fine solids and go back to active mud tank for reuse. Some client let the liquid part discharged from VG dryer go back to active mud tank system directly. This is also OK.

GN Solids Control just receive order from waste management service company (call this client WMSC for short in below chapter). WMSC is waste management service company with many years jobsite experience, their main client is CNPC and SINOPEC. With China new policy on environmental protection, WMSC is faced with booming business project with CNPC & SINOPEC, requiring more waste management equipment to support their project.  As China leading manufacturer for solids control equipment & waste management equipment, GN Solids Control definitely become their main supplier.

WMSC already use our decanter centrifuge & vertical cuttings dryer & high G dryer for over 2 years for waste management project. They give high praise on GN equipment. Pls see more details of below.

GN Solids Control is professional original manufacturer for solids control equipment & drilling waste management equipment. Decanter centrifuge & vertical cuttings dryer is the key equipment of GN. In the past years, we offer over 100 sets centrifuge & over 30 sets vertical cuttings dryer every year to the oil & gas drilling field, HDD drilling, CBM drilling, diamond drilling etc. Recently, GN big bowl super high speed centrifuge GNLW363CG-VFD come to market, with G force 2908@3800RPM bowl speed, which is good choice for waste water treatment.

GN Solids Control can offer different type centrifuge, like

Small bowl mini centrifuge, middle bowl centrifuge, big bowl big volume centrifuge

Low speed centrifuge, middle speed centrifuge, high speed centrifuge, super high speed centrifuge.

GN Solids Control is leading manufacturer for Vertical cuttings dryer ( Verti-G dryer) & decanter centrifuges, which are key equipment for solids control & drilling cuttings treatment. Up to now from 2012, we already exported over 300 sets centrifuges & 50 sets vertical cuttings dryer to international oil drilling field and domestic drilling companies. The premium performance and reasonable price win good reputation for GN Solids Control.

Recently, our after sales team just come back from an Africa Drilling Company rigsite.( We call it ADC in this chapter). ADC is a drilling company with 7 land drilling rigs and all the rigs is under drilling process. From 2013, ADC contact our company and visit our factory (location is close to Beijing) many times. After that, ADC issue many big orders to us, totally including:

1) 5 sets Verti-G dryer for drilling cuttings treatment, attached with:

• 5 sets high skid to install the vertical cuttings dryer,
• 5 sets screw pump for flushing the Verti-G dryer,
• 15 sets screw conveyor to transfer drilling cuttings for feeding or for discharge.
• 5 sets one year recommended spare parts.

GN Solids Control Verti-G dryer (vertical cuttings dryer) is verified high quality products in many drilling rig site, like Shell jobsite, Baker Hughes drilling site etc. Even compared with CSI vertical cuttings dryer, in some bad mud cuttings conditions, GN Solids brand Verti-G dryer can also work in high performance. This is also the technology accumulation with many years research, test and jobsite experience.

Last year, we have exported over 10 sets verti-G dryer with screw conveyors to Middle East, the main client is NIDC. As Iran government strict policy on environment protection, GN Solids Control have a big chance to match large quantity of verti-G dryer with screw conveyors for NIDC drilling rigs.

One package of verti-G dryer with screw conveyors including below items:

GNMS-500D mud system is economic standard offer for diamond drilling rigs / gold exploration clients. With this unit, the solids in millimeter level can be removed out 98%, and 100microns to 1mm can be removed 64%, and 2microns to 100microns can be removed 25%. GNMS-500D mud system is 2 phase separation unit with shale shaker & desander cones. If the user wants to remove more fine solids, other equipment is required to get better performance.

We can do below improvements based on GNMS-500D mud system.

Every year we have big budget for oil & gas drilling show which include solids control equipment exhibition. This year, we also attend many oil equipment exhibitions in different countries and areas.

1) Nigeria oil & gas exhibition in March.

Nigeria is leading country in oil drilling field in West Africa. We have lots of valuable customer there. The main customer business is to offer solids control service or drilling waste management service with centrifuge, vertical cuttings dryer & high G dryer. There are also some drilling companies with several land drilling rigs who service themselves with GN Solids Control equipment directly.

Nigeria oil & gas exhibition NOG, holding in capacity city Abuja, is attracting more and more visitors every year. GN Solids Control take waste management decanter centrifuge there.

Oily sludge treatment is very important: environmental protection, oil recovery, water separation. We just finish one project for COSL, the China largest offshore drilling company. You can check details from here:  COSL oily waste treated by GN centrifuge with chemical enhancement.  Recently, we receive one project requirements from Africa and they need us to offer proposal for oily sludge treatment. Their goal is to separate the oil and water, to incinerate the solids. And we offer 2 solutions below:

Option A: solution for oily sludge treatment – High G dryer + oil water separator + TDU

Step 1: Use high G dryer to treat the oily sludge and separate into two groups: solids and liquid.

Step 2: use oil water separator to separate liquids into oil and water

Step 3: use Thermal desorption unit to incinerate the solids.

Comments: this solution with better performance, but it is very costly because of TDU.

Solidification and stabilization are separate treatment techniques with similar goals. Solidification of wastes involves the production of a solid mass having sufficiently high structural integrity to allow transport and/or disposal of the solid without requiring secondary containment, i.e. mixing of sludge with shredded paper, sawdust, etc.

This technique converts hydrologic sensitive liquid and semi-liquids waste in a physical form that can be stored safely and conveniently. Stabilization, however, involves the immobilization of constituents in wastes by chemical alteration to form insoluble compounds, or by entrapment within the solidified product. The Stabilization/Solidification systems provide an effective method for processing oil-base waste producing an environmentally safe, dry material that is acceptable for onsite burial, land farming or disposal at an approved waste facility. The most commonly used industrial systems are lime based, cement based, silicates based, clay based, pozolanic and thermoplastic.

Both Stabilization and solidification are classified as fixation processes applied to oil waste when the main purpose is to immobilize, isolate, or in some other way contain the contaminant from solids or semisolids waste.

In both cases the target is:

• 1. Improve the handling and physical characteristics of the waste
• 2. Reduce the surface area available for transferring or losing the contaminant and restricting the fluid mobilization through the total volume of hard matrix
• 3. Reduce the contaminant’s solubility into the waste volume
