Indirect Fired Thermal Desorption System
With proposed Thermal Desorption system, hydrocarbons are separated from the solids in the sludge. The treated solids/sludge may have zero residual hydrocarbons, resulting in an end product that can be disposed cost-effectively without harming environment.
Technology overcomes many of the disadvantages associated with mechanical and other thermal technologies for desorption of hydrocarbons. Thermal process chamber is designed to have a large open capacity with low vapor exit velocity. By minimizing particulate in the vapor stream the recovered hydrocarbons are clean and can be used as fuel to heat the system or resold.
Technology incorporates multiple heating zones along the length of the drum. This allows applying 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 or customer's requirements for residual hydrocarbons.
System can be mobile should customer will require.
