Inquiry from clients of Decanter centrifuges for slurry separation

We are looking for a Decanter centrifuge suitable for foundation industry. We are a Qatar based construction company involved in the deep foundation for high rise buildings, bridges, industrial plants etc. We are using world renowned drilling machines from Bauer Germany and SANY china for drilling the vertical holes in the ground to a depth of ranging from 15 meter ~65 meter. We have got diaphragm wall cutters to do the rectangular vertical drilling in the ground. We normally use bentonite or polymer slurry during drilling. We are already using Desanders & desilters for separating the solids from slurry to make it reusable. Continue reading “Decanter centrifuges for slurry separation”

Dredged slurry Separation system is one division of GN mud separation market.We manufacture Dredged slurry Separation equipments and system in China based factory,and ship our slurry separation system and equipments

around the world

GN Dredged slurry Separation system

The GN 2000 GPM dredged slurry separation system has been designed specifically to accept feed directly from the dredge at a maximum rate  2000 gpm, GN slurry separation system unique self contained solid removal technology separates solids from dredged slurry via a three stage system down to 25 um. In addition, the solids that are removed are dewatered to a stackable “pass paint filter” state, which can be readily moved with front end loader, conveyor and/or dump trucks. The effluent or discharged fluid is pumped off by a centrifugal pump. The separation process is continuous and operates completely mechanically without any chemical enhancement. The entire dredged slurry separation system is designed onto a “rock over” type trailer that is highway legal for ease of transporting.

We are looking for Drilling Cuttings Screw Conveyors partner,since we are solids control system manufacturer.When designing a total mud system,we need to integrate drilling cuttings screw conveyors.

1. Drilling Cuttings Screw Conveyors (Augers)

1 x ±24ft screw type cutting conveyor fitted with independent electrical motor and with sensor capable to stop the engine if any alien body is engaged into the screw.

Conveyor should be calculated to absorb overflow of cuttings when drilling 26” or 17” hole (1000gpm flow rate).

1 x ±36ft screw type cutting conveyor as above.Which are used before the drilling mud shale shakers.

We only work with manufacturer for drilling type cuttings converor,if you are interested,please send your info. to info@gnsolidscontrol.com.

GN design drilling mud trip tank for petroleum drilling mud circulation system.GN mud agitators and centrifugal pumps are components for  the mud trip tank .With GN experienced engineers,our selection for the mud mixers and trip pumps are compatible for the trip tank.

Drilling mud trip tank definition

Drilling mud trip tank is a small mud tank with a capacity of 10 to 15 barrels, usually with 1-barrel or H-barrel

divisions, used to ascertain the amount of mud necessary to keep the wellbore  full with the exact amount of mud that is displaced by drill pipe. When the bit comes out of the hole, a volume of mud equal to that which the drill pipe occupied while in the hole must be pumped into the hole to replace the pipe. When the bit goes back in the hole, the drill pipe displaces a certain amount of mud, and a trip tank can be used again to keep track of this volume.

Mud gas separator sizing and design selection is important for petroleum well drilling.Welcome to consult GN for the right sizing and fit design for your mud gas separator in oilfield drilling mud.

Mud/Gas Separator Sizing and Evaluation

Recent wellsite disasters have led to an increased emphasis on properly sized mud/gas separators. To assure safty,we

should know mud/gas separator technology and recommends separator configuration, components, design considerations, and a sizing procedure. A simple method of evaluating mud/gas separation within the separator vessel has been developed as a basis for the sizing procedure. A mud/gas separator sizing worksheet will assist drilling personnel with the sizing calculations. The worksheet provides a quick and easy evaluation of most mud/gas separators for a specific well application. A brief discussion of other mud/gas separator considerations is provided, including separator components, testing, materials, and oil-based-mud considerations.

The mud/gas separator is designed to provide effective separation of the mud and gas circulated from the well by venting the gas and returning the mud to the mud pits. Small amounts of entrained gas can then be handled by a vacuum-type degasser located in the mud pits. The mud/gas separator controls gas cutting during kick situations, during drilling with significant drilled gas in the mud returns, or when trip gas is circulated up.
