The purpose of vertical cutting dryer is help oil rig to meet and excess the current and upcoming environmental regulation and control the operation cost effectively.  Separate the solids contents in the drilling fluid will maximum the life use of drilling fluid yet the solids remove drilling fluid need to be properly process so it will not contaminate the earth soil by removing moisture as much as possible.  The vertical cutting dryer working concept is similar like garment washer in high speed spinning mode.  The inside of the vertical cutting dryer contain the screens to filter the solids.  Yet in continues high speed spinning usage, the screen often get clogged and need to stop during the process.  To encounter this issue, GN Solids Control’s vertical cutting dryer feather air knife inside the dryer to prevent clogging the screen.

Air knife is a high compress air system blow off liquid and debris wile object that need to be process in continuous moving motion.  The “knife” produce uniform sheet of laminar airflow pressurized air containing a series of holes or continuous slots through which pressurized air exits in a laminar flow pattern.  This impact of air can be from mist breeze to high velocity without making contact with object.

Air knives remove liquids, control the dense of liquids, dry the liquid covering, remove solids particles, cooling the surfaces or create a press force to assist in the mechanical bonding of materials to the surface. Electrical currents from anti-static bars can also be injected into the exit air knife stream to eliminate the static electricity charge on some surfaces.

The most common use of air knives is to contain or remove flowing materials (liquids or solids) from the surface of material. The applications include drying solids to prevent solids stick on the screen.   They can also different temperature air to a surface, or create an invisible air barrier to separate heated or cooled environments.

GN Solids control can provide you high quality vertical cuttings dryer and best after sale service.

GN Solids Control is the first private company who develop vertical cuttings dryer, to compete with USA/ Europe verti-G dryer brand.

Desanding plant also called desanding unit. It is more and more widely used for pipe construction, micro tunneling, water well drilling, HDD, CBM, or other kind of trenchless projects. As more and more government increase the standard for discharge, drilled mud cannot be discharged directly as previous. Recovery system like desanding unit is as a necessary request of the trenchless machine and rigs.

 

There are many customers they do not use the desanding plant before, and do not have much understanding on the application and function of the desanding system. Blow is the normal question they will ask.

 

Question 1: What is the function of the desanding unit mud system? What we can get from the system?

The desanding unit is used to recovery clean mud from the drilled mud. There are big quantity clean mud in the drilling mud came out from well head. The desanding unit can be used to recovery the clean mud, and reuse it for drilling activity. It can reduce your cost on drilling mud. As most of the clean mud in drilling cuttings have been recovered by the system, it reduces the quantity of solids charge. And after separation of shale shaker and cyclone parts, the solids discharge become dryer and easy for transport.

 

Question 2: How is the desanding unit mud system working?

There are normally 2 or 3 phase separation for the dirty mud from trenchless drilling rig.

The 1rst phase solids control separation: Dirty mud will be fed to shale shaker for to separate the bigger sides solids.

The 2nd phase solids control separation: 10’’ Desander cone. Mud from shale shaker transferred to desander cone through centrifugal feeding pump, solids above 47 microns can be removed after this step.

The 3rd phase solids control separation: 4’’ Desilter cone. Clean mud from desander cone will come out from top of the cone assembly and flow to the desander tank, solids will be discharged outside the system. There will be a centrifugal pump used to transfer mud from desander tank and feed to desilter cone. Solids above 27 microns can be removed after this step.

Operator can choose to only use desander cone or desilter cone, or use both per jobsite condition.

Mixing system is optional for customer. Customer can choose to combined system with mixing, or a separation system with separate mixing, or even build the mixing system locally.

After the Spring Festival Holiday, GN back to work for a while, the Inventory of the solids control equipment in Houston has already upgraded. The main equipment available right now are the shale shaker, mud cleaner and decanter centrifuge. These units are requested very often by the customer once the rig starting for setting up.

The shale shaker stocked in GN Houston warehouse is a type of linear motion vibration mode. 4 panel screens design makes it large working area and long time for the drilling mud stay on the screen thus the cuttings discharged out would be much dryer. It is worthy to mention that the screen matched this shaker model GNZS594E is interchangeable with the original Mongoose screen. Same dimension while the difference is material used. GN’s screen is steel frame which is price competitive than the original ones. The Vibration motor used are from Italy Oli or American Martin, both of this 2 brands are acceptable by The States markets.

The mud cleaner stocked is the model of 1000GPM on capacity with 2 pcs 10 inch de-sander cone and 12 pcs de-silter cones. The under flow shale shaker is the same model with the stocked ones for easy maintenance and future spare parts requirements from the customer.

On considering the request for the shaker screen, GN solids also made inventory for the shaker screen size of 23×46 inch from API 60 to API 230. Right now the stock quantity of the shale shaker and mud cleaner are separately 10 units and 6 units. These units could be delivered within 3 days after the order is placed.

The decanter centrifuge stocked is the new version C type model GNLW363CG. Comparing with the BG model, CG has several upgrades on the designs including the feed tube installation location, the adding of solids discharge block ring which could effectively avoid the cutting gathering in the collection box.

In oil and gas drilling industry, the decanter centrifuge can be utilized for barite recovery, ultra fine solids separation and drilling waste cuttings management. Based on the different application and customers’ specific request, GN provides the centrifuge sometimes within the mud recycling system in which the centrifuge is installed on the mud tank. Some clients want to locate the centrifuge on the frame for simple operation and maintenance.

 

Once the centrifuge installed on the mud tank, it is usually utilized for barite recovery or ultra fine solids separation. Within the traditional mud recycling system, the drilling mud could be treated in series by shale shaker, desander & desilter, decanter centrifuge. 2-centriuge product is now the most popular design that could apply for the barite recovery and ultra fine solids separation. This 2 centrifuge is situated as middle speed model first and high speed second. This is a broadly acceptable layout for solids control system.

 

With increasingly more rules are released for restricting the release of drilling waste, the drilling companies pay much more attention on maximum drilling liquids recovery. Thus the drilling waste management is granularly entering the drilling industry. Additionally, it request our high speed centrifuge to recuperate the drilling liquids as maximum as possible. Therefore, some companies only get the job done for the drilling waste cuttings separation.

 

Sometimes the contractor don’t equip centrifuge within the mud recycling system because of cost consideration or low requirement on mud cleanness. The centrifuge service could be supplied by other drilling mud company. The centrifuge having a high support frame is bought in cause it may be utilized for the last stage solids control and drilling waste management.

 

GN Solids Control provides the decanter centrifuge support frame according to customers’ requirement. Even the customer would request the decanter centrifuge and frame support drawing, they fabricate the frame themselves, also is a great choice for centrifuge service
