Abstract

The pilot unit is developed for adaptation of the absorptive mathematical model in a scrubber of the Venturi on a finding of factors of phase equilibrium by algorithm working off in the absorptive processes of extraction SO2 on water. The technique of work by test tests of trapping CO2 for water which have shown adequate work of a scrubber of the Venturi in the cascade with a spray separator-cyclone separator is completed.

Highlights

At the present stage of human development more than 850 mln t of nitrogen oxides, 150 mln t of sulfur dioxide, 310 mln t of carbon monoxide, 250 mln t of carbon dioxide, and 3 mln t of hydrocarbons are released into the atmosphere in the world annually [1]
Air is supplied by the blower into injector 1, where sulfur oxides or other gases from the furnace are injected; the formed gas mixture enters the Venturi scrubber, where oxides are absorbed by water with various additives
Gas and water flow rates are measured at the scrubber inlet, gas concentrations are measured in air at the scrubber inlet and gas outlet from the cyclone

Summary

Introduction

Energy companies supply to the atmosphere more than 23% of emissions from all stationary sources in the Russian Federation. Among these emissions, nitrogen oxides accounts for about 97-98% (vol.), and others are sulfur oxides and various substances. Nitrogen and sulfur oxides in the flue gases are the toxic substances, and in the case of their mixing with air moisture, they form acids, which, falling to the earth in the form of socalled acid rains, damage the farmlands, destroy engineering structures, and harm human health and all living things on Earth.
