Hazardous waste treatment solutions for oil and gas industry - Oil, Gas & Refineries

There are a wide amount of applications for our VacuDry® process within the oil and gas industry. A large variety of wastes and by-products that are generated in the oil & gas production chain can be treated effectively and sustainably. In past decades, numerous thermal desorption processes have been implemented worldwide, using a variety of heating chamber designs to separate hydrocarbons from the mineral solids. Such standard TDUs work under atmospheric pressure which can lead to safety risks, high energy consumption, larger emissions and limited flexibility regarding altering feed materials. Due to its unique design, the complications outlined above are avoided throughout the VacuDry® process. When it comes to treating standard oily wastes, mercury-containing waste streams, NORM, and especially for the recovery of highly valuable drilling fluids from drill cuttings; our vacuum thermal desorption process (i.e. vacuum distillation) is economically unbeatable.
