Oilfield drilling waste management system is mainly depends on flocculent unit, dewatering centrifuge, vertical cuttings dryer, solidification unit, thermal desorption unit. Recently, we deliver one set of flocculent unit with dewatering centrifuge for China domestic market. The client uses the product to deal with waste water after drilling operation.

GN Solids Control is China & USA based leading supplier for solids control equipment & drilling waste management equipment. Our equipment includes solids control equipment, mud system, drilling waste management equipment etc.

Recently, we ship one set drilling cuttings solidification unit to Africa client. The client is local professional oil Service Company with many years experience in solids control & drilling waste management. Formerly, the client wants to buy US brand fixation unit. However, the client checks the design of our fixation unit, and then compare the price with US brand fixation unit. Finally, the client choose GN Solids Control brand for the fixation unit.

GN drilling cuttings fixation unit composed of below items.

1) One hopper to collect drilling waste from shaker discharge / mud cleaner discharge / centrifuge discharge

2) One screw conveyor connected with waste hopper, transfer the screw conveyor to mixing blender.

3) Two sets stainless steel chemical box with screw conveyor installed on both side of blender, to add curing agent or cement

4) One mixing blender to mix the curing agent / cement with drilling waste.

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.

GN Solids Control is supporting company for oil gas drilling & drilling waste management field. As leading manufacturer for solids control equipment & waste management equipment, every year we give best support to over 10 big projects in domestic market and over 10 sets big projects in overseas market.  GN mud centrifuge, Vertical cuttings dryer, solidification unit, Thermal Desorption unit are the key equipment for drilling waste management / oily sludge treatment.

Recently, we have one overseas customer with 4 projects requirement:

– 1st Project:

Treatment of old drill cuttings waste pits – 3000 M3/ waste pit (mixture of OBM & WBM) using solidification process or by a better treatment process such s Thermal Desorption process.

Client Goal: OOC < 5%

GN proposal: we offer 1 sets solidification unit to reach client goal.

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
