C.T.O

 

Technology overview

"One of the biggest interest in VOC destruction device of Oxidation type is to minimize the fuel consumption because the security of economic efficiency is a very important criteria in selecting and maintaining destruction devices.
Resolution of VOC substance is highly efficient and maintains perfect performance during processing when combusted at high temperature over 800℃, however, the system is made to oxidize by catalyst at relatively low temperature of 300~450℃ in order to reduce fuel cost. The gas containing VOC substance through catalytic oxidation is made to achieve over 95% of destruction efficiency, therefore the system is economically efficient in terms of fuel consumption, however requires the catalyst replacement after a certain period."

 

Technology fundamentals

"Catalyst is made to maintain stable catalytic property by having highly active platinum or Palladium metal plated in supporting carrier. The organic element of VOC component is catalytic oxidized by at low temperature and then reacted with H2O and CO2, which is environmentally safe."

 

Process

"VOC substance gas is pre-heated through heat exchanger and then flowed into combustion chamber where appropriate temperature for catalytic oxidation of 300~450℃ is maintained. While passing through the catalytic layer, the gas is combusted by catalytic thermal oxidation. Combustion burner is made to maintain an even temperature by auto control of combusted air amount through temperature control device(TIC), installed in combustion chamber. The heat exchanger that has already recovered discharging energy recovers approximately 65% of VOC gas in-flow by pre heating. In the event that additional heat recovery is required, the 2nd heat recovery may be installed in business place to recover the heat once more."

 

 

 

 

 

Features of CTO

Low temperature processing requires low fuel consumption, therefore highly economic.
Simple structure and easy maintenance.
Either horizontal or vertical installation depending on the land condition on site.
Expensive catalytic replacement cost.
A separate pre-treatment is required when flowing in substances that may result in catalyst poisons such as Halide, Sox, organic silicon, and tar.
