Abstract:
The inventions are related to industrial processing of combustible carbon- and hydrocarbon products. A method of processing combustible carbon- and hydrocarbon products is implemented using a reactor equipped with temperature sensors. The reactors comprise the phases of heating the charge (13), pyrolysis of combustible components and coking (12), combustion (11), and formation of a solid residue (4). At the phases of heating the charge (13) and coking and pyrolysis (12), an aerosol (i.e. dust particles and condensed liquid droplets carried away from the combustion zone (11) sorption zone (21) is formed by flushing the upper part of the charge by liquid hydrocarbonaceous products through the dispenser (22) and/or by adding to the batch the solid hydrocarbonaceous products having a softening point above 60° C. and the end boiling point above 300° C. The plant includes a reactor (either of the two aforementioned models), the discharge assembly for discharging of solid and non-combustible by-products (27), the gas-vapor mixture discharge unit (28), a cyclone separator for coarse filtering (cleaning unit for purification and removing the solid and liquid carbonaceous particles) (29), liquid products condensation unit (30), Florence flasks for condensates (31), and liquid hydrocarbon waste tank sump (32). Between the cyclone-type cleaning unit for purification and removing the solid and liquid carbonaceous particles (29) and the liquid products condensation unit (30), there is an additional gas-vapor mixture purification unit (33), consisting of a centrifugal separator for fine purification (34) and one selective-type cyclone (35). The liquid hydrocarbon waste tank sump (32) is equipped with a feed dispenser for their charging to the dispenser (22) located at the upper lid of the reactor (3). The invention allows to improve the quality of purification of the gas-vapor mixture from solid and liquid-drop impurities up to 95%, increase the process productivity and simplify the required hardware design. The invention improves the quality of the gas-vapor mixture purification from solid and liquid-drop impurities for up to 95 percent, increases the process productivity and simplifies the hardware design. 4 independent claims, 16 dependent claims, 4 figures, 3 tables, 3 examples.
Abstract:
The present invention relates to an apparatus for heat-treating waste matters, and more particularly an ecological apparatus for heat-treating waste matters, which enables waste matters such as various industrial wastes, city-living wastes and various high polymeric chemical wastes to be subjected to heat treatment at a lower temperature under vacuum in a heat-treating vessel without discharging pollutants produced during the heat treatment such as carbon, tar, noxious gases, malodors, and dust by treatment in a filter mechanism.

Abstract:
A moving bed gasification/thermal treatment reactor includes a geometry in which moving bed reactor particles serve as both a moving bed filter and a heat carrier to provide thermal energy for thermal treatment reactions, such that the moving bed filter and the heat carrier are one and the same to remove solid particulates or droplets generated by thermal treatment processes or injected into the moving bed filter from other sources.
Abstract:
Apparatus for treating gases produced from the conversion of coal, e.g., from carbonization of coal, to remove the undesirable constituents thereof is disclosed. The method involves passing the hot raw gases from the coal conversation process over a coke bed at a temperature of more than 1100.degree. K. The coke bed is located in the coal gasification reactor and is provided with an ordinary air supply. The subject method achieves a significant reduction in undesirable constituents in the gas and eliminates the need for auxiliary gas treatment systems, oxygen production systems and the like.
Abstract:
A method of treating a gas current which is obtained from coal by gasification comprises compressing the gas in several stages and prior to the entrance into a subsequent stage, cooling and separating the liquid from at least a portion of the gas and then heating the cooled and separated gas. The apparatus includes a plurality of compression stages with at least one of the stages having connections to a cooler and a water separator through which the gases pass and including a heater for treating at least the portion of the gas which passed through the cooler and separator and which is then delivered into a conduit for transferring all of the removed gas from the previous stage into a subsequent stage.
