80,000 Nm³/h Regenerative Thermal Oxidizer & 10,000 Nm³/h Rotary Concentrator

A technology company in Shenzhen, specializing in the production of conductive glass for LCDs, color filters, LCD panels, and capacitive touch screens, among other components widely used in smartphones, tablets, PMPs, digital cameras, camcorders, GPS navigators, and other display products. The company remains steadfastly focused on the R&D and production of upstream materials for the flat-panel display industry, holding a clear technological advantage.

Exhaust Gas Sources and Composition

Sources:

This project primarily treats VOC emissions from 1 RTR pilot line and associated mixing and coating rooms in the production facility.

• Pilot line exhaust: ~11,000 m³/h

• Mixing/coating room exhaust: ~2,700 m³/h

Main Components:

Methyl ethyl ketone (MEK), propylene glycol monomethyl ether (PGME), methyl isobutyl ketone (MIBK), etc., with an average mixed concentration of ~2,800 mg/m³.

Design Solution

Based on the client’s facility conditions, the project deploys:

• 1 × 80,000 Nm³/h Rotary RTO

• 1 × 10,000 Nm³/h Rotary Concentrator Rotary Concentrator

Process Flow:

• The first two high-concentration drying ovens from the RTR pilot line discharge directly into the Rotary RTO for incineration.

• The remaining five low-concentration drying exhaust gases are cooled through heat exchange cooling before being mixed with emissions from the mixing/coating rooms, then fed into the Rotary Concentrator Rotary Concentrator for concentration, and then sent to the RTO.

• Energy recovery: Heat exchanged from the latter five ovens and RTO-purified air is used to preheat incoming air for the RTR pilot line, significantly reducing energy consumption.

Project Advantages

YURCENT’s proprietary third-generation Rotary RTO offers:

✅ Advanced technology – High efficiency, compact footprint, low operational costs

✅ Dual benefits – Ensures environmental compliance while boosting economic returns

The system has completed commissioning and operating stably at all designed performance metrics.
