Many industrial processes take place often under high temperatures. One of the greatest problems is overheating of surrounding structural elements in contact with hot gases. This increases the thermal load on materials and reduces the service life of constructions. The construction of efficient cooling systems is very complex and time-consuming and presents a technical challenge. The invention addresses the problem of providing a method, which ensures separation of hot gases from construction walls while allowing high gas temperatures to be achieved in the working region. The problem is solved with a method, which is characterized in that a hot gas is kept in continuous rotation in a chamber, wherein the rotating gas forms a thermally insulating gas layer due to the effect of centrifugal force, and overheating of the chamber walls is avoided thereby. Using the invention can significantly reduce heat losses and thus energy consumption. Higher efficiencies can be achieved. According to the invention, construction materials which are more lightweight and cost-effective than conventional ones (e.g. aluminium alloys instead of heat-resistant steels) can advantageously be used. Costs for maintenance and operation can be significantly lowered by reducing heat losses.

Systems and methods achieve the conversion of polymer containing material into petroleum products such as hydrocarbon gas, wax, crude oil and diesel. The reactor and its system are designed to subject the polymer containing material to pyrolysis in a way that results in a higher petroleum product yield than conventional existing systems. The system has controls which allow for the heating temperature, rotation of the body, and throughput rate, to be adjusted depending on the reaction time required for the material inside the reactor. The condensing system is able to separate the products into the desired petroleum products by percentage output ranging from wax to crude-like oil to diesel-quality oil.

The present application provides a continuous preparation system and method for vinylidene chloride. In the present application, by coupling two stages of high gravity reactors, the product vinylidene chloride and water vapor are distilled from a reaction system in form of an azeotrope by adopting a water vapor steam stripping method, and the product obtained using the method has high purity. In addition, by combining steam stripping and high gravity, trichloroethane and alkali solution are rapidly mixed for mass transfer, and the product vinylidene chloride is rapidly distilled from the reaction system in form of the azeotrope (based on rapid diffusion of water vapor), such that the reaction proceeds continuously towards the direction of producing vinylidene chloride, thus significantly improving the conversion rate. As proved by a test apparatus, the present application can stabilize the purity of the vinylidene chloride product at 98% or more (mass fraction), decrease the TOC value of chloride salt wastewater to 100 mg/L or less, and decrease the consumption of materials and the cost of subsequent salt-containing wastewater treatment.
