solidification unit

The water based mud drilling cuttings treatment solution including cuttings solidification unit and waster based mud drilling cuttings treatment system.

High G drying shaker is core equipment for primary solids control and drying the water based cuttings, to meet the requirement of final disposal and recover more base fluids. The features of high G drying shaker is that high G force adjustable up to 8 G, flexible feeding method such as weir feed, top feed and hopper feed, mechanical deck angle adjustable while working from -1 to 5 degree. The high G drying shaker can lay under the primary shale shaker directly to collect the water based drilling cuttings from primary shale shaker. Or it can lay on a separate mud tank, to collect drilling cuttings from screw conveyor or waste vacuum pump.
The working process of high G drying shaker system is as below:
The screw conveyor collect the water based drilling cuttings from primary shale shaker and transfer to high G drying shaker, which is lay on the fluids catching tank, the centrifuge feeding pump feed the fluids to waste decanter centrifuge for fine solids separation, the fluids flow to intermediate tank, the clean fluids can be transferred to solids control system storage tank or mud mixing tank by adding chemical additives. The discharged solids together with the separated cuttings from desander, desilter and decanter centrifuge will be transferred by screw conveyor to solidification unit, by adding lime and absorber and mixed in the high shear vessel. The mixed solids can be final disposal without damage to the environment.

With chemical dosing unit, the dewatering centrifuge can separate the ultra fine solids up to 1 microns, the clean water can be sent to waste water treatment facility for disposal or recovery to solids control system for drilling rig reuse.

GN drilling mud dewatering unit and solidification unit are successfully used in Africa jobsite.

The drilling mud dewatering unit is ideal equipment to treat the water based drilling mud, it consists of VFD decanter centrifuge, chemical dosing unit, centrifuge feeding pump and fluids collection tank, all of the equipments are installed inside the container. By adding proper chemicals, most of the ultra fine solids are separated out from the fluids and collect in the tank, the solids are separated out and collected by cuttings box and screw conveyor to transfer to the big hopper of the solidification unit. The decanter centrifuge bowl is made of duplex stainless steel 2205 or 2304, the other bowl components are made of SS316L, the screw propeller is made of stainless steel material, and it is protected by tungsten carbide tiles, the open type propeller design will increase the treating efficiency.

Solidification unit is the equipments to solidify materials so that the treated materials can be moved or landfilled without leakage to meet environmental protection standard. The discharged cuttings are collected in the big collection hopper and transferred by the bottom screw conveyor, the solidification materials are storage into 2 box, one is with absorbents, the other one is with cement, each box with its own transfer conveyor, the cuttings are mixed with the absorbents and cement in the shear mixer automatically.
If the user use the cuttings solidification unit directly, the consumption of the absorber and cements will be very huge, which makes the treatment cost not competitive. The drilling mud dewatering unit will reduce the moisture of the drilling mud effectively and the cuttings solidification unit can use less volume chemicals, and the discharged fluids can be reused or sent to third party water treatment facility for further treatment.
