Plasma and plasma-chemical technologies in the modern world find various applications in various branches and spheres of human activity from metallurgy and high-temperature synthesis of new substances to medicine - surgical operations with the help of a plasma scalpel, which provides cutting and restoring blood vessels simultaneously.
The study of plasma gasification of solid waste is an area of applied sciences where Russia holds the leading position in the world. According to F.G. Rutberg, Academician of the Russian Academy of Sciences, Director of the Institute of Electrophysics and Electric Power Engineering of the Russian Academy of Sciences, winner of the Global Energy international prize for 2011 - “In the world in 10-15 years of use, plasma is more than metallurgy and chemistry combined.”

An experimental installation for plasma gasification of solid waste is being operated at the Institute of Electrophysics and Electric Power of the Russian Academy of Sciences. With the help of this experimental facility, technologies are being developed for processing various types of solid waste, the production of synthesis gas, which can be used in the power industry or as a raw material for the chemical industry.
The Installation of plasma gasification consists of following basic components: the reactor for gasification, generators of plasma with power supply systems, an afterburner, system of cooling and clearing of departing gases. High-voltage plasma generators of an alternating current of industrial frequency with capacity up to 50 kW and using the environment air for formation of plasma are applying.
The basic principle of the installation is as follows: high-temperature plasma gasification with the possible production of electricity or utilization of residual heat followed by a multi-stage flue gas cleaning in accordance with environmental protection standards.
Chemical reaction of the plasma gasification, process temperature 1200 – 1500 ⁰C:
(C, CxHy) + Air + H2O → H2 + CO + CO2 + N2 + O2 + H2O + Ar + CH4 + NOx + SO2 + H2S

The installation of plasma gasification of solid waste allows us to simultaneously solve two problems: recycling of wood, coal, plastic, RDF, automobile tires and the production of energy from renewable sources (alternative energy).
The process of plasma gasification carried out at a temperature of more than 1200 ° C, avoids the appearance in the synthesis gas of liquid fractions (resins), which are formed in significant quantities at lower temperatures, which eliminates the need for their further processing. The high process temperature ensures complete destruction of toxic and hardly decomposable waste components and, in the presence of chlorine-containing components in the waste, eliminates the synthesis of secondary, especially toxic substances.
The resulting synthesis gas can be combusted in a gas boiler room and serve as a partial replacement for natural gas or be subjected to additional treatment (purification) for further use as a raw material in the chemical industry.
The gas analysis system based on the Ostec GAOS MS-20-1 process mass spectrometer, built into the installation of plasma gasification of solid waste, allows you to control the process, optimize operating parameters, monitor the overall performance of the exhaust gas cleaning system, monitor harmful emissions in the atmosphere.
