Implementation of the program of import substitution considered on the example of pilot tests (PT) of reagents produced by NPF Travers LLC. The existing water chemistry of steam boilers and heat recovery steam boilers of RN-Tuapsinsky Oil Refinery LLC gas-turbine power plant is organized with the use of complex reagent Helamin BWR-150H. Considering the advantages and disadvantages of complex reagents for the organization of water chemistry, it was proposed to conduct PT of reagents AMINAT KO-4 based on a mixture of polyphosphates to prevent scale formation on heat transfer surfaces and AMINAT PK-2 based on mixtures of neutralizing amines to prevent carbon dioxide corrosion. The article presents the results of the PT, which showed that the correctional water chemistry of boilers using reagents AMINAT ensured the maintenance of the regulatory requirements of the regime maps of the equipment, as well as minimizing the processes of corrosion, scale formation and sludge formation during the entire period of work. Based on the results obtained, conclusions were drawn on the technical and economic feasibility of using these reagents.
