Containerized Systems from GN to the World

GN have been working a lot on how to modularize the whole system, for different applications, dispite all the customizations, there is always one solution which seems very popular, containerize. Though different people get different understanding on the containerize, either put into container to save shipping cost, or make itself as container size, to save all hassles afterwards. 

Recently we delivered two containerized systems, one is for HDD, the other is for OST.

This HDD mud recycling system is a high configuration including all 4 stages separation equipment. Below is the list of this system. 1. Shale shaker GNZS703F is the first stage separation equipment to remove the coarse solids. GNZS03F is the latest version shale shaker in GN production line. This model shale shaker is with 3 panel composite frame shaker screen that is fastened by using ratchet spanner, easily and fast.2. GNZJ703F-1S8N mud cleaner is combination unit of desander and desilter. The mud cleaner under shaker is the same model GNZS703F. Normally, GN use same model shale shaker for easy future maintenance. 2 units centrifugal pump are equipped in the system for feeding the drilling mud to the hydrocyclone units for smaller sand and silt separation. 3. Shale shaker and mud cleaner are firstly fixed on a strong steel frame. The frame bottom is same dimension with the under located mud tank. This frame can be lifted easily with shaker and mud cleaner installed on it for easy assembling and transportation.

4. Decanter centrifuge GNLW363C-VFD is last stage separation equipment for fine solids separation. After several time recycling, there will be much fine solids in the drilling mud. The centrifuge is used to remove the fine solids to ensure the property of the drilling mud. Decanter centrifuge is fixed on a collecting tank with 4 supporting legs. Liquid is flow into the tank and solids will be collected by the screw conveyor and transferred out of the system.

This containerized oil sludge treatment system is consisting of below modules:1. Premixing Module – per customer requirement, GN provided the sludge vacuum pump to transfer the oil sludge from the collection pit to the system. Two tanks equipped with agitators and heating line are used as the premixing vessel.2. Coarse Screen Module – the washed sludge will be pumped to the coarse shaker screen for large size solid particles separation. A flushing pipe is installed over the shaker deck to spray washing the sludge. For warm consideration, the shaker unit is put in a container, and the complete container will be put on a collecting tank to store the treated slurry.3. Fine Solids Separation Module – slurry treated by the shaker will be pumped to the decanter centrifuge for fine solids separation. For easy collection of the solids discharged from the centrifuge, the centrifuge is supported by a skid and a screw conveyor is installed under the centrifuge solids discharge port. 4. 3 Phase Separation Skid Module – The slurry out of the decanter will flow into the 3 phase separation module that includes inclined plate clarifier, oil water separator and surge tanks for separated oil and water. The 3 phase separation module is the last process procedure of the oil sludge separation system.5. Chemical Dosing Module – the chemicals can be added into each procedure of the system. The dosing system is also installed in a container and connected to each procedure via pipes and valves. GN is able to provide the oil sludge system with customized color and client’s logo for better advertisement of client’s business. Please feel free to contact with GN for more separation solutions.

All the the tanks, frames can be designed to meet the specific requirement from site. freely get in touch with GN for your detail requirement.

Oil Sludge Treatment System to Europe Client

Oil sludge now has been a more and more serious issue, many different sources, different backgrounds, but normally what we are facing is either a farm collecting oil sludge, or a pit, where was collecting the oilly sludge. On our site, we saw drill rigs, we saw the beam pumping machines, and we understand where these sludge comes. After checked the site many times, and experience from other area in the world, the client developed this system with GN, and keep giving GN more and more info to help GN improve the system and equipment. This containerized oil sludge treatment system is consisting of below modules: 1. Premixing Module – per customer requirement, GN provided the sludge vacuum pump to transfer the oil sludge from the collection pit to the system. Two tanks equipped with agitators and heating line are used as the premixing vessel. 2. Coarse Screen Module – the washed sludge will be pumped to the coarse shaker screen for large size solid particles separation. A flushing pipe is installed over the shaker deck to spray washing the sludge. For warm consideration, the shaker unit is put in a container, and the complete container will be put on a collecting tank to store the treated slurry. 3. Fine Solids Separation Module – slurry treated by the shaker will be pumped to the decanter centrifuge for fine solids separation. For easy collection of the solids discharged from the centrifuge, the centrifuge is supported by a skid and a screw conveyor is installed under the centrifuge solids discharge port.  4. 3 Phase Separation Skid Module – The slurry out of the decanter will flow into the 3 phase separation module that includes inclined plate clarifier, oil water separator and surge tanks for separated oil and water. The 3 phase separation module is the last process procedure of the oil sludge separation system.

Oil Sludge Treatment System to American Client

Oil sludge now has been a more and more serious issue, many different sources, different backgrounds, but normally what we are facing is either a farm collecting oil sludge, or a pit, where was collecting the oilly sludge. It is not a new technology, but we have a special machine, we need your equipment to do the separation together. This client is offering service, with a full package of equipment, to separate the oil / water / solids step by step. The ordered oil sludge treatment system is GN 2 cubic meters per hour model. Client is going to use this system as a demo to verify it is workable in recovering the oil from oil sludge. Actually, the excellent performance of GN oil sludge treatment system has been proved onsite. In this system, client plan to bring their SMO (shear, mixing and oxidation) unit to connect with GN oil sludge system for better demulsification performance. The system includs a premixing module, a classify system, then down to a shaker modular, decanter module, then to last step disc stac. While as we all know the mixture always goes to 3section, water / oil / solids, though it is not clearly just doing this, it is in one way or the other separating by themselves, or in each and every step, it is doing the same thing, then the whole flow changes.  GN has another oil sludge treatment system with capacity of 15 cubic meters per hours is almost done, now is the final assembly procedure. And we are upgrading the DEMO system, to make it more suitable for different applications, then it will be easier in future to have our system to the site to do some real test.

Another OBM DWM system for CNPC

Oil based mud have been widely used, and since it is oil based, drilling waste will be always a bigger problem than other mud waste. Since knowing GN Solids Control cuttings dryer are widely used in the world wide, and reading the comments from Baker Hughes that GN equipment efficiency is even better thant he equivileant EU /US products, now more and more CNPC project is using GN products.  Recently, GN finished the fabrication of one set oil based drilling cuttings treatment system for CNPC project. Before, CNPC has ever purchased several units drilling cuttings treatment system from GN Solids Control.The drilling cuttings treatment system is used to treat the drilling cuttings discharged from primary solids control equipment like shale shaker, mud cleaner and barite recovery decanter centrifuge. For environment protection and cost saving consideration, the drilling operators is using the cuttings treatment system to recover more drilling fluids from cuttings, in the meanwhile, less waste will be discharged into the nature. To increase the working efficiency, GN released the vacuum pump unit that performs well to transfer cuttings sludge to treatment system. This oil based cuttings treatment system is a compact design with all relevant equipment mounted on one skid for easy position on drill site. The equipment lists as below:1.Cuttings Dryer unit – this is the main equipment used to remove the large size cuttings and recover oil base drilling fluids. After treated by this unit, the OOC will be going down to less 5%. It is the most important equipment in this cuttings treatment system.2. High Speed Decanter Centrifuge – the decanter centrifuge is used to polish the effluence liquid coming from the dryer unit by remove the fine solid particles. With a speed up to 3200rpm, the centrifuge will remove the solids bigger than 5 microns to make the drilling fluids more acceptable for reusing. 3. The skid of the system is designed to with a buffer tank that is divided into 2 compartments. First compartment is used for collecting the drilling fluid from the dryer unit, and the second compartment is to store the polished drilling fluids after treated by centrifuge. GN is using the Netzsch screw pump to transfer the fluids from first tank compartment to the centrifuge unit. This is quite a standard design while GN is capable and open for more customizations, to meet different site requirement, and even doing more research on the final step, TDU, or find other way to reuse the carbon.
