Emission control in printing with RTO

Printing industry drying

Printing is a vital industry, and it has many environmental challenges. One of the most significant issues is air pollution. The printing process produces many volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and other pollutants, which can cause severe damage to the environment and human health. Therefore, it is essential to control emissions from printing facilities. Regenerative Thermal Oxidizers (RTOs) are an effective solution for emission control in printing.

What is Regenerative Thermal Oxidizer (RTO)?

RTO is an advanced emission control technology that uses high temperatures and oxidation to destroy pollutants. The system consists of a combustion chamber, heat exchanger, and control system. The RTO works by preheating the process air and then passing it through a bed of ceramic media. The ceramic media is heated by the hot exhaust gas from the combustion chamber, and the process air is heated to the combustion temperature, which is typically between 1400¡ãF to 1600¡ãF (760¡ãC to 870¡ãC). The heated process air is then directed into the oxidation chamber, where pollutants are oxidized and destroyed.

Why is RTO effective for emission control in printing?

RTO can destroy up to 99% of VOCs and HAPs emissions from printing facilities.
RTO can handle high-volume airflows, which are common in printing processes.
RTO is energy-efficient and can recover up to 95% of the heat generated during the oxidation process, which can significantly reduce energy costs.
RTO is easy to operate and maintain, and it has a long lifespan.

How does RTO work for different printing processes?

Flexographic printing

Flexographic printing is a popular printing process that uses flexible plates to transfer ink onto a substrate. The process produces a lot of VOCs emissions, especially during the ink drying stage. RTOs can effectively control emissions from flexographic printing by treating the exhaust air from the drying ovens.

Gravure printing

Gravure printing is another common printing process that uses a rotary printing press to transfer ink onto a substrate. The process produces a lot of VOCs emissions, especially during the ink curing stage. RTOs can effectively control emissions from gravure printing by treating the exhaust air from the curing ovens.

Offset printing

Offset printing is a widely used printing process that uses a flat printing plate to transfer ink onto a substrate. The process produces a lot of VOCs emissions, especially during the ink drying and curing stages. RTOs can effectively control emissions from offset printing by treating the exhaust air from the drying and curing ovens.

Concluzie

Emission control in printing is a critical environmental issue, and RTOs are an effective solution to this problem. RTOs can handle high-volume airflows and can destroy up to 99% of VOCs and HAPs emissions from printing processes. RTOs are energy-efficient, easy to operate and maintain, and have a long lifespan. Therefore, printing facilities should consider using RTOs to control emissions and protect the environment and human health.
