RTO for Petrochemical Plant

RTO for Petrochemical Plant

CASE STUDY
REGENERATIVE THERMAL OXIDIZER (RTO)
WITH DUST COLLECTOR FOR A PRE-FILTER
Client:  DuPont’s EVA Copolymer plant
Location:   Beijing, China
 
Background:    Air Clear LLC worked in conjunction with its License Tri-Tech to provide and install a Regenerative Thermal Oxidizer (RTO) for a new EVA copolymer petrochemical plant near Beijing, China. In order to protect the structured ceramic heat recovery beds from the  solid particulate in the exhaust a dust collector was used to pre-filter the process air and prevent plugging and loss of TER (thermal energy recovery). The nature of the process mandated that additional safety precautions be taken. An FDA (flame detonation arrestor) was installed to eliminate the possibility of a ‘flashback‘ to the process. A ‘Z’ purge was incorporated into the control panel making the insides inert eliminating the potential for explosions.
Solution:   Air Clear engineers designed, fabricated, and installed a three-chamber Regenerative Thermal Oxidizer (RTO) with a purge, hot bypass system, capable of oxidizing 48,000 NMfor the petrochemical plant. The emission requirements were successfully met exceeding 99% DRE
The entire Thermal Energy Recovery RTO system was designed by Air Clear and a majority of the mechanical system was fabricated locally in China under stringent Air Clear supervision.  This reduced capital costs for the customer while maintaining Air Clear’s high-quality requirements.

A PLC system was used to provide flexible, easy, remote operation of the entire system.  In addition, Air Clear included features that allow Air Clear engineers to monitor and troubleshoot the system operation from the United States. This dramatically improves on-line productivity.
