Centrifuges is widely used for oil gas driling, piling projects. In whihch applications, big bowl is more and more popular, eg. 30in decanter centrifuge GNLW764 from GN Solids Control is known to more and more piling contractors. In this CIPPE 2017, GN will bring one unit to Beijing.

As for HDD projects, lots of people have tried, but it is not quite modularized, as too many different requirement based on that. For the strict applicaition, GNLW553, GNLW554 should be good options, because of the high flow capacity. Polymer is a good help for the not too high speed, concentrate the small solids, while lots of places do not like chemicals in disposal.
So what do we need in HDD mud system, that depends, but basically a few points as listed:
– recycle the water
– reuse the solids
– dump the solids (with / without chemical)
– dump water to water treatement plant
Some important index will be:

  • moisture of the solids (1 – dry solids / total)
  • TSS (total suspended solids) in water result

Then if we can figure out what equipment is using before centrifuge, and how is the performance, then we will find out if we need use the centrifuge continuously or not, which is important for definning the capacity.

A separate skid is a very flexible choice for HDD projects, as normally it is not in the system, not with the rig package, so far it is a customize solution. And with a flexible frame, will be easier to arrange the solids / liquid discharge.

Contact with GN if you are in need of a solution.

As a leader of solids control equipment manufacturers in China, GN keep investing on new products, and as keep providing good quality products, built our international brand name. In the past 2016, GN have made some quite new products which we did not manufacture before: the centrifugal degasser, and the vacuum transfer pump.
Couple weeks ago, GN finished the fabrication of centrifugal type degasser, this enriched GN’s production line. This centrifugal degasser is designed and manufactured after researching many types of degassers home and abroad. It could be used in all kinds of drilling fluids recycling system to remove the gas in the gas cut-in drilling fluids for recovering the mud property, stabilizing mud viscosity and reducing drilling cost.
After a few project, keep buying the vacuum transfer pump, we finally decided to do some research and development on our own vacuum transfering. With our partners help, we finish and test it on site with good performance.
What we keep improving
Shale Shaker
One of the weakeness of Chinese shaker is we do not have a small sump underneath to make the fluids more flexible, to be able to flow to sides of the shakers, which also supposed to make things easier when design the mud tanks with mud ditch to easier balance mud flow. Now here it comes, we will show this type shakers in this exhibition, more details pls chase with our sales team.
Decanter centrifuge is our main products, and keep improving, each and every year, it is also a highlight to our competitors even.
If you are interested in more infomration, keep tune.
Sludges that contain oil and water are generated via a sort of movements and procedures on board ships, including sedimentation in tanks, tank dewatering techniques, and leaks or cleaning cycles in backflush filters and separators for treating fuel oil and lube oil. The pattern for combusting excessive density gas oils of bigger viscosity, as good as the use of residues as a fuel for medium-velocity diesel engines, also increases the production of sludge from both fuel oil and lube oil.
Emergence of sludges containing oil and water
The construct up of those oil and water-containing sludges represents a enormous disposal concern. Options which have frequently been employed to maintain them comprise incinerating the sludge on board, or taking away it on land. Nevertheless, incineration is an steeply-priced process in view that the sludge has to be dewatered by way of evaporators and then mixed with priceless diesel oil to generate a combustible fuel. Disposal on land can be related to giant expenses, as the sludge has to be transported to a waste disposal website online, which in turn needs to be paid for.

Hongkong, like Singapore, is small place with huge business potential, not only as a transport center, or a bridge for mixing the different culture to the world. While always some first taste of new. As the connection from long history, and the developing of China. More and more Chinese brand are recognised by clients in these places.
Befor this project, another TBM project, and also some HDD project for the airport, clients choose GN products to do the separation job. This time again, a TBM project, a whole mud plant for TBM mud recycling. with equipment below:
1. GN’s proposal is 3 unit shale shakers with treating capacity of 500 GPM, or even larger. The largest advantage of GN shale shaker is simple structure for easy operation and maintenance. Hollow type rubber for sealing between the screen panel and shaker deck ensures the cleanness of the mud.

1500GPM Mud Recycling System
2. After treated by the mud cleaner, most of the useless solids larger than 20 microns would be removed out.

3. Client could optionally choose the decanter centrifugeunit with dewatering container and equip into the mud recycling system to separate the ultra fine solids in the drilling fluids. GN have designed a big bowl centrifuge specially for the tunneling projects. By using the centrifuge unit, the driller could recover more drilling fluids.

GN Mud Recycling System

Let us know your requirement, GN can also customized a solution for your operation site.

GN solids control Design and manufacture of container of combustible gas oilfield operations in the electronic déflagration system is the refinery along with gas gathering and switching exhaust and vent typically the gas processing plant, having fields of electronic combustion system can vent inflammable harmful gas ignited lose in order to eliminate its difficulties for environment and safety, is often a safe, environmental protection products. Besides used in refinery and also gas stations, oil field electric ignition device with mud gas separator, is now traditionally used in oil drilling executive.
Oil field the superiority regarding electronic ignition system
Digital ignition oil fields “artificial lighting” to “automatic operation”, reflect the humanistic thoughts and environmental demands. Making it necessary to use electronic combustion device, drilling, testing, development process, the release is often the truth. Over the past few decades, Flare feu are manual operation, persons close to flare points, can burn, burns easily, high risk; As well, the artificial operation timeframe is longer, the accuracy and reliability is not high, easy to produce toxic gas emissions for the atmosphere in great volumes, cause different degree of atmosphere pollution.
GN SOLIDS CONTROL Production of electronic feu device let the “shortcomings” stopped to exist. It can be currently of relief, timely, exact location setting off export spewed toxic flammable gas movement line, eliminating the damage connected with gas pollution to the atmosphere and human and pet.

GN power flare ignitor
Electronic ignition device besides used in refinery and filling stations, the device with mud propane separator, is now widely used inside petroleum drilling engineering, is actually a mature product, in home and sichuan oil and gas discipline in xinjiang, in spots like Iran, Egypt, venezuela abroad are using the product.
Electric ignition device is mainly made from DN200 (or 6) gasoline burner (torch), GDH : type 2 electronic igniter, firing equipment (gas tank, hose, etc . ), mud gas separator (matching) whenever used in drilling engineering, and so on This product adopts high performance electronic digital ignition circuit, its principal parts adopt imported ingredients and other parts and cables and wires with domestic high quality goods, stable performance, reliable perform.
Procedures:
Install the butano gas pipeline to safe practices of burner (torch) atmosphere inlet.
Pick up and start the actual electronic igniter current transformation and voltage amplification routine.
Open the gas tank, operating electronic igniter light source flash tube ignition (level), or directly open the particular emptying the firing on the gas valve, lit fireplace with electronic igniter pipe ignition (level 1).
Wide open the gas vent gateway cut, lit by the using up fire tube will mélodie (secondary ignition).
Close the actual gas tank, put out open fire tube, let the combustible in-take gas combustion.
