Exhaust After-treatment Equipment for Industrial Waste Gas

1, Selective Catalytic Reduction (SCR) system reactor

Function: Efficiently remove nitrogen oxides (NOx) from the exhaust gas of marine engines, it is the core technology to meet the IMO Tier III emission standards.

Principle: Under the action of a catalyst, urea solution (commonly known as diesel exhaust fluid, DEF) is used as a reducing agent to convert harmful NOx into harmless nitrogen (N₂) and water (H₂O).

Application: Mainly used for main propulsion engines and large auxiliary engines of ships.

2, Diesel Oxidation Catalyst (DOC)

Function: Effectively remove carbon monoxide (CO), hydrocarbons (HC) and some particulate matter (PM) from exhaust gases.

Principle: Through catalytic oxidation reaction, CO and HC are converted into harmless carbon dioxide (CO₂) and water (H₂O).

Application: It is commonly used for exhaust gas treatment of auxiliary machines and boilers, or as a pre-unit of SCR systems.

3, Catalytic Diesel Particulate Filter (CDPF)Function: Efficiently capture and oxidize to eliminate black smoke and particulate matter (PM/black carbon) in exhaust gas.

Principle: Particulate matter is captured by a porous wall-flow filter, and the oxidation temperature of the particulate matter is reduced by a coated catalyst to achieve continuous or periodic regeneration, maintaining the system's unobstructed state.

Application: In situations where particulate matter emissions are subject to extremely strict requirements, such as ships operating in Emission Control Areas (ECAs) or in environmentally sensitive regions.

4, Product Advantages and Features

High-efficiency purification: Utilizing high-performance catalysts, it features a high conversion rate and can ensure that ships consistently meet the most stringent emission regulations set by the IMO, EPA, and all global sea areas.

High reliability: The product is designed with a robust structure and made of high-quality materials that are resistant to high temperatures and corrosion (such as stainless steel), making it suitable for the harsh engine room environment on ships. It has a long service life and requires low maintenance.

Intelligent control: It can be seamlessly integrated with the ship's centralized control system to achieve automated operation, real-time monitoring of emission data, urea injection, back pressure and system status, ensuring safety and efficiency.

5, Flexible Adaptation: We offer a variety of specifications and models, and can provide customized design and installation based on different ship types, main engine power, and space layout. It is suitable for both new shipbuilding and retrofit projects.

Global Services: Relying on our import and export advantages, we provide equipment supply, technical consultation and after-sales service support on a global scale to ensure that our customers have no worries.
