In coming month, from December 12th to 14th, a new exhibition will be held in Thailand, focusing on the oil and gas industry, for both land rigs and offshores. The exhibitors cover the drilling industry, from the upstream to the downstream. During the exhibition, there are also professional conferences to be held.

About GN Solids Control

You may already know the three biggest oil and gas exhibitions in the world, one is the OTC in Houston, which is scheduled in each May in Houston, the technology center of the oil and gas industry, one is CIPPE which is held in Beijing, the capital of China, because China is becoming the biggest manufacturer and an up-rising technology R&D center, and also the ADIPEC, which is based in Abu Dhabi, one central city of Middle East, where the largest oil is located in. This exhibition in Thailand is hosted by the same company as ADIPEC.

Value of Asia: Asia has the largest population in the world. China and India are two of the biggest oil consumers and also the equipment manufacturers. Also the south Asian countries like Indonesia, Thailand, Malaysia and Singapore are also exploring oil reserves in adjacent seas. Some international big oil companies are locating their branch companies in those countries, and their business and contracts are covering regions as far as Africa.

Exhibition Name: Future Energy Asia
Exhibition Location: BITEC, BANGKOK, Thailand, from Dec 12th to 14th
GN booth: D40.

GN Will Bring Screen Samples to Exhibition, why?

GN BIG BOWL CENTRIFUGE

By far, the decanter centrifuge is a quite efficient equipment for separating the solids from the liquid, which is widely used in many industries form the winery, plant oil to the energy industry like the oil and gas drilling, waste management, cuttings treatment and oily sludge separation. Not long ago, 2 sets of GNLW764-VFD centrifuges were delivered to a desert jobsite for a coal mine project, for washing the coals.
When a place is remote, especially in a desert place, all resources are more precious than usual. In that project, the decanter centrifuges are only a part of the whole project but are playing an important role. They are requested to run continuously and to treat around 100 cubic meter material in each hour, in order to save cost by two means: one is to collect the limited water to be reused in next washing procedure, the second is to dry the coal and finally change it into money. The more water to be recycled, the lower cost the project pay for, and the more coal to be collected, the more benefit the project earn from.
Decanter centrifuges are one of GN Solids Control’s core products, and GN has centrifuges for different applications, including: mining and other industry, oil gas drilling solids control and waste management for the cuttings and drilling mud, oily sludge separation works like the waste treatment in refinery and from tank cleaning, the animal waste treatment in farmlands, food industry like the plant oil and wineries.
In a word, an efficient decanter centrifuge helps the end user to cut cost, save money and increase the final products quality, like the purer liquid and drier solids. If you have such need for centrifuges or need more information about centrifuge, welcome to contact GN Solids Control for consultancy.

Just last week, GN Solids Control has finished a compact mud recycling unit, with full steps for separation for one of the largest oil giants in China. This system is to be transported to the jobsite by end of this year.

This system has 4 steps of separation, including:

1. GNZS703F. Shale shakers are always the first step for separation, because of GN shakers’ high G force and accurate API complied shaker screens, this shale shaker can efficiently separate out all particles larger than 100 microns, there in hence to help with prolonging the service life of the centrifugal pump after the shaker.

2. GNZJ703F-1S8N Mud Cleaner. Mud cleaner is a combined machine of desander and desilter, at a smaller foot print. It uses interchangeable shaker screens as GNZS703F, 2 centrifugal pumps are used to feed the desander and desilter respectively.

3. GNSP series Centrifugal pumps are also GN’s own products. For material choosing, GN used the high quality anti-weary material as pump body material by hard ductile iron alloy, and the main pump body is thicker than other manufacturers’. All GNSB series centrifugal pumps are using stainless steel mechanical seals.

4. Tank and skid for above mentioned equipment. Above mentioned equipment are located as 2 blocks. One block is a skid with lifting and anchoring corners just as a 20ft container, and the shale shaker and mud cleaner are located in the skid during transportation and operation. That design facilitates the operator for transportation or lifting the whole skid onto a tank, no to adjust each equipment or pipeline’s position.

5. A tank with compartments are designed to storage the mud from the shaker and from the desander/desilter. On below the tank, there are some slots for installing the centrifugal pumps. The whole outsize of the tank is also same as a 20ft container with container corners for lifting.

Last week, one international contactor for mining industry started their project in Australia, among the separation line, two green colored equipment were significantly shown. They are big bowl centrifuges from GN Solids Control, a leading manufacturer for industrial separating equipment manufacturer based in China.

GN Solids Control has been designing and producing the separating equipment like shale shakers, mud cleaners, decanter centrifuges, vertical cuttings dryers for many years. At first, the equipment are mainly used for the oil and gas drilling solids control systems, and later, as GN’s quickly increasing development of technology and producing capability, GN Solids Control has enlarged its centrifuge model range from 14 inch bowl to bigger ones and smaller ones. Those 2 sets of GNLW764A decanter centrifuges are till now the biggest sized centrifuges made by GN Solids Control, with a bowl diameter of 30 inch and a treating capacity up to 120cbm/hr.

Besides the giant bowl decanter centrifuge GNLW764A-VFD, GN Solids Control has various centrifuge models with size as small as 9 inch diameter bowl, up to 30 inch diameter bowl, including the 14 inch bowl , 18 inch bowl, 22 inch bowl and etc.

GNLW764

For each size, there are different models available per different bowl length diameter ratios. Normally the comparably longer bowl a centrifuge has, a cleaner separation result it could give. Among GNLW series decanter centrifuges, take the 18 inch bowl diameter as example, there are different ratios like 2, 3 and 4. GNLW452 is a stout shaped decanter centrifuge with middle speed and shorter bowl, which is mostly used for barite recovery in a solids control system based on the barite size and gravity. GNLW453 is a high speed centrifuge for waste management systems, or as the dewatering centrifuge, for fine particles. While the GNLW454 is quite suitable for waste water separation with a longer bowl up to 4 times of bowl diameter, around 61 inches.

GNLW764, the 30 inch bowl diameter centrifuge has a bowl length-diameter up to 4. And this giant could separate quite fine particles at a large capacity, even after a dewatering unit.

In order to meet customers’ request and to help solve the problems faced in front of customers from the more and more strict environmental protection rules, GN Solids Control designed and put into market a comprehensive design for the oily sludge separation unit, and now GN Solids Control is leading in this industry.
In recent 3 years, GN Solids Control has customized several sets of similar systems, and such systems are being used in many different countries both in domestic China and overseas. It is widely used for treating the discharged slurry and sands from crude oil tank cleaning, oily waste discharged from refineries, and the viscosity oily waste from solids control for oil and gas drilling. It helps to reduce the cost for waste transportation and oil recycle, and gained good comments from under users.

OILY SLUDGE SEPARATION

A complete system is combined by several sections:
1. Pre heating and pre mixing system. In this system, a mixing tank with heating facilities are being employed. A chemical dosing system is used for adding some polymer or something else into the oily sludge and heating is used for reducing the viscosity. Later, the sludge is to be treated by a shale shaker, by which the large particles are separated out.
2. A high speed decanter centrifuge is used in next step for treating out the fine particles from the liquid. Floating unit is kind of oil water separation, and the light of weight oil will float on surface of liquid and it would be scraped out to an oil tank. The settled down particles would be drained from bottom of the IPC unit.
3. A disc centrifuge is used to separate out the small amount of particles from the liquid, and further separate the oil from water. Then the water flows into the water tank, while oil flows into the oil tank.
In the complete system, by using the complicated manifold and valves, the end user can bypass or invite into loop some equipment based on the sludge’s condition.

It is a common knowledge that in the solids control system for a drilling rig, no matter for the land rigs or for the offshores, the shale shaker plays the most important role for separating out the solids waste from the mud recycling unit, and it is also the shale shaker which waste the most of the liquid on the cuttings discharged from the shaker. That’s why, in many countries, there is a must to equip another drilling cuttings treatment system alongside the rig.
A drilling cuttings waste management system is used for further separation of the drilling waste discharged from the shale shaker and mud cleaner, most of which are from the shakers. For one thing, the drilling cuttings waste management system helps to dry the cuttings for later transportation, on the other hand, it increased the drilling liquid amount to be recycled. Both are saving money. In case of OBM mud, the operators always need a vertical cuttings dryer and a high speed decanter centrifuge, while for WBM mud, operators always use a high G drying shaker and a decanter centrifuge.
In some cases, the ViST Shaker screen device could replace the drilling cuttings waste management system, or at least to some degree, reduced the work for the cuttings separation works. Generally speaking, the ViST shaker screen device has following advantages:

ViST shaker device

1. It is suitable for both WBM and OBM mud in a solids control system.
2. It is a compact structure, and only use an air compressor as power source, and one set of ViST could serve up to 3 sets of shale shakers.
3. It is designed to be suitable for different shaker models.
4. In practice, it helps to save the liquid amount by 30% to 50%.
Now for GNZS703 and GNZS594 series shale shakers, there are ViST device for option.
