China Yurcent's Regenerative Thermal Oxidizer Support a Printing Project in Russia
Recently, in Saint Petersburg — known as the “Pearl of the Baltic Sea” — a landmark industrial waste gas treatment project has completed its installation phase. A leading Russian printing company has introduced two sets of high-efficiency Regenerative Thermal Oxidizer (RTO) systems, provided by a Chinese engineering team, at its modern production facility to address the environmental challenges associated with high-end printing operations. This project marks another significant milestone for the application of advanced Chinese VOCs (Volatile Organic Compounds) control technology in the Russian market
Project Background: Meeting Stringent Standards and Practicing Green Manufacturing
With the growing global emphasis on environmental protection, Russia's local environmental regulations have become increasingly strict. During the company's production process, a large volume of organic waste gas containing ethyl acetate and n-propanol is generated. If discharged directly, these VOC components could pose potential risks to both the environment and human health.
To address this, the company made a substantial investment to build a comprehensive, efficient, and reliable end-of-pipe treatment system covering its entire production line. The goal is not only to meet current regulatory requirements but also to fulfill its corporate social responsibility and establish a green, sustainable, and modern manufacturing facility.
Technical Core: Dual RTOs in Parallel — Building a High-Efficiency Treatment Hub
The core of this project lies in the installation of two RTO units, each designed to handle an air volume of 50,000 Nm³/h. This configuration fully accommodates the large-scale and high exhaust volume characteristics of the printing production line.
High Purification Efficiency:
RTO technology oxidizes and decomposes organic waste gases by heating them to temperatures above 760°C, converting Harmful Vocs into harmless carbon dioxide and water vapor. The purification efficiency remains stably above 99%.
High Thermal Efficiency:
The “regenerative” design features ceramic heat storage media that efficiently recover heat generated during combustion to preheat the incoming waste gas. This significantly reduces fuel consumption during operation. When treating high-calorific waste gases such as ethyl acetate, the system can even achieve “fuel-free operation”, resulting in remarkable energy savings.
Stable and Reliable Operation:
The dual parallel RTO configuration provides excellent operational flexibility. Each unit can be independently started or stopped according to production load requirements to optimize energy usage. Moreover, if one unit requires maintenance, the other can continue operating to support part of the production line, ensuring continuous and stable system performance.
Outlook
The successful implementation of this project not only enhances the printing company’s environmental image and market competitiveness but also sets a new benchmark for Chinese environmental protection equipment and technology serving markets along the Belt and Road Initiative.
