Is zeolite wheel with RTO suitable for low air flow conditions?

Zeolite wheel additionRTOThe combination of high air volume and low concentration VOCs is widely recognizedwaste gas treatmentOne of the standard technical routes. But many companies have limited air flow, perhaps only a few thousand to 20000 cubic meters per hour. Is this combination suitable for low air flow conditions? The answer is often negative.

The function of zeolite wheel is to concentrate high air volume and low concentration exhaust gas into low air volume and high concentration exhaust gas, and then send it to small-scale RTO incineration. The core advantage of this combination is that it can significantly reduce energy consumption when dealing with high air volume. But when the original air volume itself is not large, adding a zeolite wheel actually adds an extra piece of equipment, increasing investment costs and footprint. The wheel itself requires regular high-temperature regeneration, which also consumes additional heat energy. For low air flow conditions, use RTO directly or use it directlyactivated charcoalAdsorption is more economical than adding wheels.

So what process is suitable for low wind volume and medium concentration working conditions? The condensation membrane separation process is a worthwhile option to consider. This process does not require a concentration wheel, and the exhaust gas directly enters the condensation unit, where the organic matter is liquefied and separated through multi-stage cooling. The uncondensed gas passes through the membrane module, and the selective permeation of the membrane enriches the organic matter back into the inlet, further improving the recovery rate. The entire process is simple and compact, making it very suitable for scenarios with air volumes below 20000 cubic meters per hour. LuoyangWohong PetrochemicalEquipment Co., Ltd. has specially designed a modular condensing membrane separation integrated machine for low air flow conditions, occupying only a few square meters, with a short installation cycle and much lower investment than the combination of zeolite impeller and RTO.

Therefore, when choosing a technology route, enterprises should not blindly apply the solutions of large projects. The best practice for small air volume is to have a small air volume. The condensation film method not only recovers value but also avoids unnecessary equipment stacking, making it a more rational choice for low air flow conditions.
