Saving Energy In Regenerative Oxidizers

By Grigori A. Bunimovich and Yurii Sh. Matros,  Matros Technologies |

Oxidation of volatile organic compounds (VOCs) in regenerative thermal oxidizers (RTOs) is the most common process in the chemical process industries (CPI) for removing diluted emissions of VOCs and carbon monoxide from stationary air- pollution sources. Thousands of RTOs operate in automobile, engineered wood, chemical and other industries. RTOs combine gas-phase thermal oxidation of VOCs with regenerative heat exchange. Heat energy of exhaust gas is efficiently reused for heating the inlet gas. Typical process temperatures are between 1,400 and 1,800 ºF. Despite the high degree of energy recuperation, many large RTOs require substantial consumption of auxiliary fuel. An alternative to thermal oxidation is catalytic oxidation of VOCs, which runs at much lower temperatures — about 500–900 ºF. A regenerative catalytic oxidizer (RCO) uses the same operating principle as RTO, but consumes substantially less auxiliary fuel. The authors have found that in many situations, RTOs can be retrofitted to RCOs. Energy savings after such a retrofit can quickly justify the costs for the catalysts and installation. This article discusses basic RTO and RCO technology with an emphasis on thermal efficiency and energy balance.…
