Mud Solids Control Equipment

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

GN Solids Control is big producer for solids control equipment & drilling waste management equipment. As oil price going down, the solids control market become cold because of rig stop drilling, fund problem etc. Under this background, GN Solids Control put forward series of policy to support the market and to support the sales amount.

Policy 1: GN Solids Control will expand drilling waste management market and stock some equipment to give quicker response. Now, we are producing 40 sets of decanter centrifuge, 20sets of vertical cuttings dryer, 40 sets of high G drying shaker to stock the main equipment. All of them are key equipment to treat the water based mud drilling cuttings before the oil waste can go to Thermal desorption units.

GN high G shaker for water based mud drilling cuttings treatment, have two models for choose. One model is only High G shaker without beneath tank.  In this case, the operator should design one cement pit or separate mud tank to hold the liquid part after High G shaker.  The other model is High G shaker with beneath tank for fast use.

After High G shaker, high speed and variable speed centrifuge will be used for fine solids separation. GN Solids Control design decanter centrifuge with height adjustable skid for convenient use.

Recently, we have one drilling waste management service customer who buys 1 sets high G shaker with beneath tank and 1 set variable speed centrifuge with high skid. The detailed technical specifications as below:

1) High G shaker with beneath tank: The shaker is GNZS594HGE-LD shaker with 4 panel shaker screen (composite material frame screen and steel frame screen both available). The drying time should be longer than 2 panel or 3 panel shaker, and the performance should be much better. The shaker with hopper type feeding, total height is much lower than weir type feeding or box type feeding, match better with drilling cuttings treatment job.

Shale shaker is the first stage solids control equipment for oil & gas drilling mud system. The large volume of wearing parts on shale shaker is shaker screen. As America supplier shaker screen is very high cost, many drilling company source shaker screen from China. But some China supplier always gets complaint from end users. Why?

GN Solids Control is China leading manufacturer for solids control & drilling waste management & shaker screens. We can offer replacement screen for Derrick shale shaker, Swaco Mongoose shaker, and NOV brandt king cobra shaker. After many years experience on shaker screen, we do some conclusion on why end user complain on the screen and how to avoid this things happen or how to reduce the happening chance.

1) The end user pay less than half price but want to get almost same effect with America original shaker screen supplier.

For example, GN shaker screen may about 1/3 to 1/2 price compared with America brand. But life time and performance may about 70% to 80% compared with America brand. In this case, the customer actually has a better cost-effective result.
