Technology Information
The physical principles of the proposed technology consist in the generation of a low-temperature atmospheric pressure plasma. The main element of the plasma gas treatment plants with an applied electric field “CORSTRIM®” is a three-stage pulse voltage generator according to the Fitch scheme (GINF) and reactor chambers (RC). The RCs are grounded cylindrical cases with coaxially located multipoint central high-voltage electrodes or flat systems with sawtooth electrodes. Nanosecond high voltage voltage pulses of positive polarity in the reactor chambers generate pulsed corona plasma. in the interelectrode space with the simultaneous application of a constant electric field. Such a plasma is characterized by significant electron densities and energies capable of creating high concentrations of active intermediate particles (atomic oxygen, OH ions and radicals *) in the discharge gap. As a result of plasma-chemical reactions, gaseous impurities are converted to environmentally friendly gases or aerosols. Due to the high bulk density of the charges, both the generated aerosols and those available in the gases are charged and, under the influence of a constant electric field, are discarded to the grounded electrode as in a standard wet electrostatic precipitator, from where they are washed off with water. Excess ozone is again converted to oxygen in the ozone destructor. Installations can work around the clock in automatic mode.| Pollution | Concentration mg/m3 |

- Corstrim, in contrast to the devices available on the market, also acts as an electrostatic precipitator and has a closed water circulation system that washes away all contaminants from the walls of the reactor chambers (pipes).
- Installations can work around the clock in automatic mode
- No need to replace very expensive sorbents (catalysts)

Сapital expenditures AND Operating cost
The average capital cost can be estimated as 12 euro per 1 m3 of gas to be cleaned. Installation is in automatic mode and is under the supervision of the operator of the main equipment The operator must complete 8 hour course in the theory and practice of supervision. During the warranty period, the service installation is done by the employees of the enterprise , which produces equipment , after - or the same workers under the contract , or specially trained personnel.
Operating expenses consist of costs for electricity, water , surcharge operator and maintenance costs.
Energy costs are easy to calculate the data in Table 1 (Column Specific power (Wh/m3 mg). To do this, the data presented in this column are multiplied by the air flow , the concentration of pollution and the cost of 1 kWh of electricity.
