TL;DR: In this article, a mixture of crude liquid and steam is concentrated by multistage evaporation, and the vapours produced thereby are thermally oxidised or condensed, with the oxygen necessary for the incineration being provided by the gas flow, preferably air.
Abstract: The crude liquid is concentrated by multistage evaporation (A) The vapours produced thereby are thermally oxidised or condensed The concentrate with a high salt content is thermally separated in a gas/solid fluidised bed (B) into solid inorganic components (salts and solids) and organic vapours and steam, which leave the fluidised bed with the fluidising gas flow In the downstream incineration device (C), the organic compounds are thermally oxidised at temperatures >/= 800 DEG C, with the oxygen necessary for the incineration being provided by the gas flow, preferably air The heat evolved in the incineration can be used to heat the fluidising air flow and to evaporate the crude liquid

TL;DR: In this paper, it was found that the brush discharge ignition hazard with IIA gases/vapours (propane) can be eliminated by reducing the oxygen/nitrogen volume ratio in the atmosphere to the order of 15/85.

TL;DR: In this paper, a method for producing a cold cathode is described, which is a substrate having a carbon film applied to it, and the carbon film has an irregular structure consisting of carbon micro-ridges and/or micro-threads which are perpendicular to the surface of the substrate.
Abstract: The present invention relates to the production of highly efficient films for field-effect electron emitters, wherein said films may be used in the production of flat displays in electronic microscopes, in microwave electronics, in light sources, etc. This invention more precisely relates to a cold cathode that comprises a substrate having a carbon film applied thereto. The carbon film has an irregular structure consisting of carbon micro-ridges and/or micro-threads which are perpendicular to the surface of the substrate, have a size ranging typically from 0.01 to 1 micron and a distribution density of between 0.1 and 10 νm-2. This invention also relates to method for producing a cold electrode, wherein said method comprises generating a DC current discharge with a current density of between 0.15 and 0.5 A/cm2 in a mixture comprising hydrogen and a carbon-containing additive, and further depositing the carbon phase on the substrate located at the anode. The deposition process is carried out in a mixture containing hydrogen and vapours of ethylic alcohol or methane, under an overall pressure of between 50 and 300 Torrs and at a substrate temperature of between 600 and 900° C. The concentration of ethylic alcohol vapours ranges from 5 to 10 % while that of methane vapours ranges from 15 to 30 %. A method for producing a cold cathode comprises generating a microwave discharge at an absorbed power of between 100 and 1000 W. This discharge is generated in a mixture containing gaseous carbon oxide as well as methane in a 0.8-1.2 concentration and under a pressure of between 10 and 200 Torrs, and the carbon phase is further deposited on the substrate at a temperature on the substrate surface that ranges from 500 to 700° C.
