Our Thermal Desorption Unit (TDU) was designed and built by US-based Vulcan Drying Systems of Missouri, USA.
Oil-based drilling muds contain large volumes of valuable, recoverable
diesel. Cracking the diesel degrades the recoverability and greatly
reduces the value. In order to maximize the volume and value of the
recovered diesel or synthetic lubricants, it is important to apply heat
to the feed progressively with maximum temperature control. Vulcan technology incorporates multiple heating zones along the length of the
drum. This allows us to apply controlled heating at different
temperatures within each zone of the drum. Typically, the first zone
evaporates the water. The middle zones are used to remove hydrocarbons
down to less than one percent, and the last zone is a polishing zone to
take off heavy hydrocarbons and meet regulatory standards for residual
hydrocarbons. Proper temperature control during desorption as well as
during cooling and condensing eliminates or reduces cracking of
hydrocarbons.
Vulcan TDU's are presently treating oilfield wastes throught the world, including the US, Canada, most of Africa and many parts of China.
As a waste management services company, we manage the collection and recycling or disposal of most industrial wastes including contaminated soils, used oil, general waste, contaminated metal drums, plastic drums and IBC containers.
