With help of our partner in Romania, AEGEAN OIL CONSULTING SRL, now we get another ViST unit for an European company.
Before the ViST comes to the market, GN have sent the ViST to an offshore site to test, the client actually are testing a few options, and finally satisfied with GN equipment result. And then we got 6 sets ViST to the site.Though the principle is simple, the shale shaker have been developed, in many different generations, due to the limited area, the mud recycling equipment on offshore platform is always with compact structure and high efficiency. The used drilling mud and waste cuttings coming from offshore platform normally will be barged to land for treatment. Thus, to maximally recover the drilling fluids will greatly reduce the time and fund cost in treating the waste cuttings. GN VIST vacuum shale shaker can greatly increase the volume of recovered drilling fluids.
Features of ViST Vacuum Shale Shaker
1. GN Vist vacuum shale shaker is suitable for OBM, WBM and SBM.
2. By using the VIST system, the drilling fluids recovered will be increased by 30%~50%, It greatly reduces the discharge of drilling waste and the cost in transporting the waste.
3. Before this VIST shale shaker, GN ever issued the high G force drying shaker to recover more drilling fluids on cuttings. By using this VIST system, the drying shaker will be no need; Moreover, the installation of VIST system will not need any extra area onsite.
4. Operator can put much finer shaker screen on the shale shaker as the ViST vacuum system increased the liquid conductance of the screen.
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.
GN team have now been back from WEFTEC, this is the second year we have been there, advanturing further to water & waste water applications. Many pumps, many stories, many centrifuges, many equipment. Water is essential, and it have been widely used, while what we need is same, clean water.
Since source differ, solution varies. Bar screens, belt press, filter press, screw press, decanter, disc, etc. Well what GN is now offering is similar solution as from oil gas / civil projects. We offer shale shaker, decanter centrifuge.
With many years development, GN decanter centrifuge is widely used in waste water treatment and some other industries. GN waste water decanter centrifuge is specially designed for waste water clarification and waste slurry dewatering. GN centrifuge sizing from 9 inch mini model to 30 inch big bowl.
GN vacuum pump is used for high solids content slurry transferring. This pump can be used in waste cutting transferring, dredging slurry transferring and even dry solid.
Slurry pump is also a key product in the system, pumping throughly to make sure all separation run efficiently.
GN is now able to offer many different solution for different project requirement, and at the same time, we manufacture high quality decanter centrifuges and shale shakers. Freely let us know your requirement, get in touch with our sales team.
