Generator Exhaust Gas Treatment Solutions Meeting QCVN 19:2009/BTNMT Standards

Diesel generators are widely used in factories, industrial parks, hospitals, schools, commercial buildings, and residential complexes to ensure a stable backup power supply. However, generator operation produces exhaust gases containing particulate matter, carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), and other pollutants that can negatively impact the environment and human health.

VIET WATER JOINT STOCK COMPANY (VIET WATER JSC) specializes in consulting, designing, constructing, and transferring technology for generator exhaust gas treatment systems. Our solutions are optimized for high treatment efficiency, low investment costs, stable operation, and full compliance with environmental regulations.

Viet Water provides:

• Generator exhaust gas treatment consulting

• Air pollution control system design

The Need for Generator Exhaust Gas Treatment

As environmental regulations become increasingly stringent, controlling emissions from diesel generators has become a critical requirement for businesses.

The primary objectives include:

• Compliance with environmental regulations

• Meeting emission standards

• Reducing hazardous air pollutants

• Improving corporate environmental responsibility

• Supporting ISO environmental management requirements

• Protecting employee health and safety

This is especially important for:

• Manufacturing plants

• Industrial parks

• Hospitals

• Schools

• Residential buildings

• Commercial centers

where standby generators operate regularly.

Characteristics of Generator Exhaust Gas

Most industrial generators use diesel fuel, producing exhaust gases that typically contain:

Carbon Monoxide (CO)

A toxic gas generated from incomplete combustion.

Nitrogen Oxides (NOx)

Formed under high-temperature combustion conditions.

Sulfur Oxides (SOx)

Generated from sulfur compounds present in diesel fuel.

Particulate Matter and Soot

Produced during fuel combustion and incomplete burning processes.

Volatile Organic Compounds (VOCs)

Organic pollutants that can affect air quality and public health.

Principles for Selecting Exhaust Gas Treatment Technology

Viet Water designs treatment systems based on the following criteria:

Cost-Effective Investment

Optimizing initial capital expenditure.

Low Operating Costs

Reducing energy consumption and maintenance expenses.

High Treatment Efficiency

Ensuring stable and reliable emission control performance.

Environmentally Friendly Technology

Minimizing secondary waste generation and environmental impact.

Regulatory Compliance

Ensuring treated emissions comply with:

QCVN 19:2009/BTNMT – National Technical Regulation on Industrial Emissions for Dust and Inorganic Substances.

Generator Exhaust Gas Treatment Technologies

Depending on generator capacity and treatment requirements, Viet Water may apply various technologies, including:

Exhaust Gas Filtration Systems

Designed to remove particulate matter and suspended pollutants from exhaust streams.

Oxidation Catalyst Systems

Catalytic oxidation converts harmful gases into less hazardous compounds while maintaining low operating costs.

Absorption Systems

Utilize specialized absorbent solutions to remove gaseous pollutants from exhaust emissions.

Viet Water Generator Exhaust Gas Treatment Technology

One of the most commonly applied solutions by Viet Water is:

Absorption Tower Combined with Industrial Exhaust Fan System

This technology is suitable for generators of various capacities and offers an optimal balance between treatment efficiency and operating cost.

System Operating Principle

Exhaust Gas Collection

Generator exhaust gases are collected through a dedicated ducting system and directed to the treatment unit.

Industrial Exhaust Fan

The exhaust fan provides sufficient airflow and pressure to:

• Transport exhaust gases through the treatment system

• Prevent gas accumulation and backpressure

• Maintain stable generator operation

Absorption Tower

Inside the absorption tower:

• Exhaust gases come into contact with absorbent solutions

• Pollutants such as SOx, CO, and other contaminants are removed

• Packing media increases the contact area between gas and absorbent

The absorbent solution is:

• Collected in a storage tank

• Recirculated for reuse

• Automatically replenished when necessary

An emergency discharge line is also provided to ensure operational safety.
