Due to the gradual convergence of national environmental legislation with European Union requirements it is necessary to conduct environmental monitoring of gas emissions of pre-heat furnace of metatitanic acid pastes. Critically analyzing the current system of clearing, it is established that technology isn’t provide the use of exhaust gas heat. As a result is an irreversible loss of 27,8 MW of heat and thermal pollution of the atmosphere; degree of purification of harmful components doesn’t exceed 55 %, which doesn’t meet modern requirements, then – a significant excess of maximum permissible concentrations of pollutants; insufficient level of dust collection, which causes loss of pigment TiO2. Overall, the current technology is ineffective and has no prospects for intensification.In the article the technological feasibility and economic viability of recycling waste and reducing energy consumption is proved. The concept of two-stage wet cleaning is proposed. Its implementation provides high separation efficiency of TiO2 particles, neutralization of harmful gas components and partial recycling of exhaust gas heat.
