Waste sludge incinerator using pyrolysis and gasification, and relative process

A continuous process for the thermal treatment of a refinery sludge, comprising the following operations: a. drying of the refinery sludge, possibly mixed with pet-coke, at a temperature ranging from 110 to 120&#xb0; C.; b. gasification of the dried sludge, at a temperature ranging from 750 to 950&#xb0; C., for a time of 30 to 60 minutes, in the presence of a gas containing oxygen and water vapour, with the associated production of synthesis gas (CO+H) and a solid residue; c. combustion of the synthesis gas at a temperature ranging from 850 to 1,200&#xb0; C. and recycling of the combustion products for the drying and gasification phases; and d. inertization of the solid residue, at a temperature ranging from 1,300 to 1,500&#xb0; C., by vitrification with plasma torches.

Process and apparatus for the thermal treatment of refinery sludge

A simple and economical process for rendering the fine fraction, from crushing of vehicles and iron scraps, capable of being used in the manufacture of bituminous or cement-based conglomerates as partial substitutes of quarry inerts. Subject of the invention is also a reactor suitable for carrying out the above process. FIG.shows an embodiment of the reactor.

Device for the precipitation of carbon particles present in exhaust gases having a voltage generator whose poles are connected with at least one electrode and the shell comprising separate internal zones where the following phenomena take place mixing of exhaust gas with air in a first zone, ionization in a second zone of the gas & air mixture coming from said first zone, ignition and precipitation in a third zone of said carbon particles present in said gas & air mixture coming from said second zone, and exhaust of the gas in which said carbon particles have been precipitated.

Device for the precipitation of particulate in exhaust gases

Device for reduction of exhaust gas particulates in an exhaust pipe, comprising in combination a two-pole high-voltage generator, and a plurality of conductors alternately connected to one or the other of the poles. The conductors constitute substantially the only obstruction to flow of exhaust gas through the pipe and occupy a total area which is less than 50% and more than 10% of the pipe cross section. Air is introduced into the pipe upstream of the conductors, and a probe analyzes the downstream gas and regulates the air introduction according to the detected composition.
