Oil sludge treatment is an important environmental challenge. It should be noted, that oil sludge is a valuable raw material, which should be refined to the extraction of useful products, as it yields environmental and economic effect.
Among the variety of methods and techniques, burning is the most common one. But the most effective, including an environmental point of view is the pyrolysis, especially low temperature as hydrocarbons, included in the oil slurry from the combustion emit a large amount of toxic combustion products..
It makes more economical sense that the relatively small amounts of oil sludge, which are distant from the stationary treatment units, are to be treated at the locations. It calls for modular build mobile units that are placed on off-road vehicles.
The main problems at mobile pyrolysis units origination are performance and reliability assurance at high temperatures, that are necessary for the treatment process, high capacity. Therefore, in mobile applications, as well as in stationary, it is necessary to provide the technical and technological methods of uniform heating throughout the volume of the sludge as existing installations have a long process due to the preferential heating only the surface layers of sludge and location of critical nodes in the areas of minimum temperatures to reduce the stress-strain state.
This article introduces a model, fully describing the construction, and all the components of the oil sludge treatment unit. Strain-stress state analysis of unit’s bottom individually and of the pyrolysis module integrally considering the excess pressure in the reactor for different configurations of the pyrolysis module design.
