    The essence of development, its description, main characteristics: Gas separators of the inertial-filtering type are a unique type of equipment combining inertial and filtering methods of gas condensate systems separation. Designs of the combined (inertial and filtering) gas separators are equipped with improved input units where prior fluid separation takes place and mechanical impurities are captured with small dispersed aerosol coagulants  and high efficient centrifugal, inertial and filtering separation elements. Combined separators are highly efficient gas cleaning from fluid in a wide range of productivity and pressure, provide long resource between regeneration and multiple regeneration, have low hydraulic resistance compared to the coalescing filters and even some gravity-inertial separators leading world manufacturers.
    Copyright protection: In the basis of separation methods and inertial filtering gas separators designs are landmark decisions. Sumy State University (SSU) acts as an invention applicant and therefore an owner of more than 10 copyright certificates and patents for means and instrument design of granulation processes of  inertial filtering separation.

    Economically attractive design for market promotion, application and implementation, performance, cost: Paying off time of new inertial filtering type gas separators – about 3 years, in case of modernization the existing separation equipment - to 1,5 years.
    Branches, ministries, departments, enterprises and organizations where the device can be used: Inertial-filtering separators are used for depuration of the natural and oil gas from fluid and mechanical impurities on the first, middle or final stages of separation at the oil refineries (OR), gas refineries (GR), as an integral equipment at the LNG processing, low temperature separation (LTS), gas dehydration plants (GDP); used for stripping at the oil absorption plants (OAP); for low temperature gas processing using condensation, absorption and rectification; at the plants for condensate/gas stabilization (CSP), for gas processing using gas fractioning, at the gas compressor stations of the main gas lines (GCS), at the underground gas storages (UGS), at the production gas compressor stations for additional pressing (PGCS), for cleaning of gas emissions before its getting into the atmosphere.
