The petrochemical industry faces significant challenges in managing emissions from industrial processes, including high concentrations of pollutants like NOx, SO2, HF, and particulate matter. Traditional methods often fall short in achieving ultra-low emission standards due to issues like catalyst poisoning and high maintenance costs. In response, petrochemical ceramic gas scrubbing has emerged as a groundbreaking approach, leveraging advanced ceramic materials to provide comprehensive air pollution control. ZTW Tech, a leader in emission control technologies, has developed integrated systems that combine ceramic catalyst filter tubes and high-temperature ceramic fiber filters to address these challenges effectively. This article delves into the technical aspects, applications, and advantages of these systems, highlighting how they revolutionize emission management across various industries.

Understanding Petrochemical Ceramic Gas Scrubbing Technology

Petrochemical ceramic gas scrubbing refers to the use of ceramic-based filtration systems to remove multiple pollutants from flue gases in petrochemical and other industrial settings. Unlike conventional methods such as布袋除尘器 (bag filters) or electrostatic precipitators, ceramic filters offer superior performance due to their nano-scale pore structures, which enable high-efficiency capture of fine particles and gaseous contaminants. ZTW Tech's systems utilize proprietary ceramic catalyst filter tubes and non-catalytic high-temperature ceramic fiber filter tubes, which are integrated into multi-tube bundles. This design allows for simultaneous removal of NOx, SO2, HF, HCl, dioxins, heavy metals, and dust, achieving emission levels well below regulatory limits. The technology is particularly suited for harsh conditions in petrochemical plants, where gases may contain sticky or corrosive components that degrade other systems.

Key components of these systems include ceramic filter tubes with nanoscale pores, which provide a high gas-to-cloth ratio and low pressure drop. This results in energy savings and extended operational life—often exceeding five years. Additionally, the ceramic materials are resistant to alkali and heavy metal poisoning, a common issue in petrochemical applications that can reduce the effectiveness of SCR (Selective Catalytic Reduction) or SNCR (Selective Non-Catalytic Reduction) systems. By integrating脱硝 (denitrification), 脱硫 (desulfurization), and除尘 (dust removal) into a single unit, ZTW Tech's solutions minimize footprint and operational complexity, making them ideal for space-constrained facilities.

ZTW Tech's Advanced Ceramic Gas Scrubbing Systems

ZTW Tech has pioneered the development of ceramic一体化多污染物超低排放烟气治理系统 (integrated multi-pollutant ultra-low emission flue gas treatment systems), which are at the core of effective petrochemical ceramic gas scrubbing. These systems employ two main types of ceramic filter elements: ceramic catalyst filter tubes for catalytic reactions and ceramic fiber filter tubes for high-temperature dust removal. The catalyst filter tubes are impregnated with specialized materials that facilitate reactions to break down NOx into harmless nitrogen and water, while the fiber filters capture particulate matter and acidic gases like SO2 and HF. This dual approach ensures comprehensive pollution control without the need for multiple separate units, reducing capital and maintenance costs.
