Drilling Cuttings from offshore drilling platform
Thermal Desorption System
A Case Study of OBM Drill Cuttings Disposal Project
The goal of any thermal desorption technology is to produce oil-free or ultra-low Total Petroleum Hydrocarbons (TPH) solids for disposal by distilling the oils from cuttings and recovering it to be reused as drilling fluid. The material to be treating including but not limited to:
-
Oily Wastes
-
Oily sludge
-
Drill cuttings
-
Sediments
-
This system is designed to deal with the drill cuttings with high oil content and cannot be treated by cuttings dryer and decanter centrifuges. Even on the same drilling platform, there are apparent differences on colors and material properties of the drilling cuttings.The oil content on cuttings may vary from 15-40%.

Oil based drilling cuttings differs greatly from different formation/location
