A case of zeolite concentrator and regenerative thermal oxidizer was studied.This equipment was used for five years.The operation status was tested and analyzed.According to the results,there was a significant deposition of high boiling substances on the windward of the zeolite concentrator.The average adsorption capacity of zeolite was 49%of the new product.The volatile organic compounds(VOCs)concentration of RTO outlet flow fluctuated greatly.Based on the analysis results,renovation and optimization plans had been proposed on safety,environmental protection,and energy conservation.Suggestions had been made for the subsequent operation and maintenance.The above was for reference by other similar enterprises.
