GN is a leading manufacturer of mud solids control system and drilling waste management system. And GN is a manufacturing with a longer history for drilling solids control equipment research from China and services in USA. With the new environment protection rules comes out in more and more countries, GN drilling waste management equipment becomes more and more worldwide famous, and exported to more and more countries.

GN Thermal desorption unit and GN Drill cuttings drying system is the most popular equipment used for waste management. But many clients are wondering about their performance, they do not know how to choose the suitable type for their projects. Below is a simple introduction to tell the difference of the 2 systems.

Brief Introduction of GN Thermal desorption unit (TDU)

It is also called TDU. It utilizes thermal desorption to treat the oily conents. Normally, the materials treated by TDU, the solids control should be no less than 40%. Other wide, it cannot be spilled well in the pyrolysis furnace.

What kind of waste sludge can be treated by GN Thermal desorption unit (TDU)

In theory, all oil type solids whose vaporization point is below 420 degree centigrade could be treated with this system. The oil type solids above mentioned is oil waste and a certain amount solids, like mixture of mud and sand. The pyrolysis furnace roller in this design heat the material in spilling way, and the material is pushed forward by shoveling plates welled with a certain angle on the roller’s inner wall. If the material is only oily mud, the spilling character would be lower.

Brief Introduction of GN Drill cuttings drying system

It utilizes different separation equipment unit to remove the solids from the fluids step by step. If The fluids can be reused for drilling.

What kind of waste can be treated by GN Drill cuttings drying system

It can be used to treat the cuttings discharged from shale shaker, desander and desilter. It cannot used to remove solids control decanter centrifuge.

Difference of Thermal desorption unit VS Drill cuttings drying system

TDU can get clean water, clean oil and very dry solids with OOC≤0.05%. But the capacity is very small, 1~2 tons per hour.

Drill cuttings drying system use vertical cuttings dryer, and high speed decanter centrifuge to treat the waste material. It can reduce OOC to 3~5%. The fluids phase can be reused for drilling. It cannot get clean end products.
