TDU

CIPPE 2017 oil show is coming in March, next month, in Beijing, Capital of China. This is the largest oil show, with same reputation to OTC and ADIPEC.  Most client from South America, Latin America and North America will attend OTC; most client from Europe, Africa, Middle East will attend ADIPEC, and most client from Asia, Australia will attend CIPPE. Each oil show will cover about one thirds of the client in the world.

GN team in CIPPE 2016

Every year, GN Solids Control will show some news things to clients. This year, the most shining product should be the huge bowl centrifuge – 30inch bowl size, with max. treating capacity 800gpm. The bowl length is 132inch, and the ration of bowl length and bowl diameter is 4.2 to 1. With the design, client can handle huge volume mud with only one unit, smaller footprint equipment. With the professional design, the big bowl centrifuge is very fine for Tunnel Boring Project Mud Cleaning, Dredging Slurry Separation, and Municipal Sewage Sludge in Purification Plants, Industry Waste Water Treatment.

Another star product should be thermal desorption unit. TDU is key equipment to treat the oil based mud drilling cuttings, as last step the lower down the OOC to 0.3%. As per the government regulations, TDU is necessary equipment to treat the OBM cuttings.

The correct process should be: use the vertical cuttings dryer first to recover the useful based mud and return it back to drilling; the solids discharged into mud skip and transport every mud skip to mud plant with TDU, and use the TDU to burn the OBM cuttings, to make the final product environmental friendly.

If you are interested with solids control equipment, or you plan to China for the CIPPE oil show, pls send email to sales@gnsolidscontrol.com;  we can arrange car for you and offer necessary assistance.

GN Solids Control has lots of visitors every year, from different areas of the world, including Russia, Australia, Egypt, Algeria, Nigeria, Kuwait, Iran, UAE, Israel, Iraq, South Africa, Romania, Argentina, Brazil etc. Some of them may require decanter centrifuges for mud service, some of them may require shale shakers, and other solids control equipment to replace the old ones at rigsite, some of them may just try to bought one new rig and want to match the solids control system with the rigs.

Recently, we have one client coming to China and visited us again. The client has bought some sets of centrifuge in past years and tries to buy more sets centrifuge and cuttings dryer for future projects. For the details, we will talk with client when he arrives at our office.

DNV CE Decanter Centrifuge

Decanter Centrifuge has a much wide application. With rotation high G force, it can separate the much fine solids from liquid; the separation efficiency is accepted by professionals in different areas. As a centrifuge professional manufacturer, we focus on oilfield service centrifuge, including centrifuge for solids control, centrifuge for barite recovery, centrifuge for oily sludge treatment etc. From this year, we also developed many other kinds of centrifuge, pls check more from GN industry centrifuges website: http://www.gnsolidscontrol.com/industry-centrifuges

GN Vertical cuttings dryer is another kinds of centrifuges. It is mainly used to recover the valuable oil based mud from the waste cuttings. General working flow: cuttings (discharged from shale shakers) transfer (via screw conveyor) to vertical cuttings dryer, after cuttings dryer, the recovered valuable oil based mud can go back to active mud system for reuse, the dry cuttings can be collected by skips, much easier for transportation.

If local policy need the oil on cuttings below 1%, thermal desorption unit is necessary. We recommend the cuttings can be outsource to TDU service companies. This is much easier for handle. If the client buy new TDU for the project, it is really much higher cost. However, GN can also offer TDU, pls check from GN website of TDU.

 

What kind of waste materials can be treated
with thermal desorption unit (TDU)

Thermal desorption unit
(TDU)
is mainly used to treat the waste solids discharged from drilling
waste management equipment
, like vertical cuttings dryer, high G drying
shaker
, decanter centrifuge, etc… In theory, all oil type solids whose vaporization
point is below 420 degree centigrade could be treated with thermal desorption
unit (TDU). The oil type solids above mentioned is oily waste with a certain
amount solids, like mixture of mud and sand, the oily sludge after tank
cleaning.

Functions of Thermal desorption (TDU) unit
for waste materials

The pyrolysis furnace roller in thermal
desorption unit (TDU) heat the waste material in spilling way, and the material
is pushed forward by shoveling plates weld with a certain angle on the roller’s
inner wall. If the material is only oily mud, the spilling character would be
lower. The Pyrolysis Oil can be used as fuel oil. Diesel and heavy oil can also
be used as alternative fuel type for the startup and running of the thermal
desorption unit.  

Many people are wondering if the thermal
desorption unit can be used to treat waste tires or not. Below explanation can
be taken for your information.

Generally speaking, the Thermal desorption
unit (TDU) is mostly designed and used for oily sludge or oil waste from oil
and gas drilling field. And it is suggested to be used only for oily sludge or
oil waste. In principle, it can be used to treat the waste tire. But you need
to take out the steel wire from the tires and chock it into small pieces and
add some extra material to prevent it to bond on the drum unit,. And the size
after bond is better no larger than 30mm*30mm*30mm. normally, the thermal
desorption unit (TDU) have the dust removal system for the gas, But depends on
the local regulations, you may need extra treatment system for the discharges.
