Waste Gas Treatment

What is exhaust gas treatment system?

Industrial waste gas treatment system is a collection of technologies and equipment used to treat and reduce exhaust gases from industrial sites. It includes methods and technologies for removing, reducing or converting pollutants in exhaust gases into substances that are neither harmful nor less harmful to the environment.

Why is it necessary to design a waste gas treatment system?

Industrial exhaust gas treatment systems are necessary as it helps to minimize adverse impacts on the environment and human health. Industrial processes often produce pollutants such as pollution exhaust gases, volatile organic compounds and other substances that can pollute the air, water and soil. If the exhaust gas is not treated effectively, it can contribute to the phenomenon of affecting human health, reducing air quality and causing serious environmental problems.

Industrial waste gas treatment technologies

Deoxidation process
The deoxidization process is one of the most effective industrial waste gas treatment methods available today. This method works by converting pollutants in the exhaust gas into non-toxic products, through oxidation. This process is performed by various types of deoxidizers such as catalytic oxidizers, thermal oxidizers, and regenerative thermal oxidizers.
Adsorption process
The adsorption method is one of the most common industrial waste gas treatment methods available today. This method uses materials that attract pollutants to remove them from the flue gas. Common adsorption materials include activated carbon, zeolite, and alumina. The adsorption process is often used to remove toxic gases such as hydrochloric acid (HCl), sulphur dioxide (SO2), and ammonia (NH3).
NOx removal process
NOx (nitrogen oxides) are one of the most common substances that negatively affect the environment and human health. NOx reduction methods are used to remove NOx from exhaust gases, through the process of transforming them into non-toxic products. The most common NOx reduction methods currently include selective catalytic reduction (SCR) and non-selective catalytic reduction (NSCR).

Process of designing and building industrial waste gas treatment system at Natural Star Vina

Here are some specific steps to give you an overview of this process:
  • Information Gathering: First, you need to gather information about the business, production size, type of industry, and regulations related to emissions treatment of the area of operation. This includes understanding the type of production emissions and annual emissions.
  • Exhaust Gas Analysis: Identify the main components of exhaust gases, including dust particles, contaminants, and other hazardous elements. This will help you decide on the appropriate treatment method.
  • Identify legal requirements: Know the environmental regulations and standards related to emissions treatment in your area. This is important to ensure compliance and avoid breaking the law.
  • Design planning: Based on the information gathered, make a plan for the design of the exhaust gas treatment system. This includes selecting appropriate treatment technologies such as filtration systems, activated carbon systems, or other measures.
  • Engineering Design: Conducts the detailed engineering design for the system, including the determination of specific dimensions, materials, and components. Ensures that the design complies with engineering and environmental standards.
  • Get a building permit: Often you need to get a permit to build an exhaust gas treatment system from the authorities. This process can be complicated and time consuming, so it needs to be done carefully.
  • Construction and installation: After obtaining the permit, start the construction and installation of the exhaust gas treatment system according to the approved design.
  • Test and Adjustment: Test the entire system to ensure proper operation. Adjust equipment and processes if necessary to achieve optimal performance.
  • Operation and maintenance: The system needs to be operated daily and maintained periodically to ensure it operates efficiently and complies with environmental and safety standards.
  • Monitoring and reporting: Continuously monitor the performance of the system and report on emissions and environmental parameters to regulatory authorities.
These processes can be adjusted depending on the type of exhaust gas treatment system, the size of the business, and specific local regulations.

What is an industrial waste gas treatment system?

  1. Exhaust Gas Collection System: This is an important part for collecting exhaust gas from the manufacturing process or from other treatment systems such as furnaces, boilers, generators, and other industrial processes. The exhaust gas collection system ensures the exhaust gas is transferred to the next treatment stages.
  2. Filtration system: Filtration technology is used to remove dust particles and solid compounds present in exhaust gases. Filtration systems typically use mechanical filters, physical filters or electrical filters.
  3. Adsorption system: Adsorption technology is used to remove gas contaminants such as odorous gases, evaporated organic gases and other polluting gases. This system uses active adsorbents such as activated carbon, zeolite, activated coke or other adsorbents to absorb and remove contaminants from exhaust gases.
  4. Reduction systems: Reduction technologies are used to reduce contaminants such as NOx gas (nitrogen oxide), SOx gas (sulfur oxide), and other contaminants by using chemical or biological processes. Common examples of reduction technologies are NOx reduction systems using reducing agents such as ammonia (NH3) or urea (NH2CONH2).
  5. Oxidation systems: Oxidation technologies are used to transform organic contaminants in exhaust gases into non-toxic or less toxic substances. Oxidation methods typically use strong oxidizers such as oxygen (O2), ozone (O3) or other chemical oxidants.
  6. Deodorization systems: Deodorization technology is used to remove odors from industrial exhaust gases. Deodorization methods typically include the use of oxidation promoters, bacteria, or other chemical processes to decompose or transform odors in exhaust gases.
  7. Exhaust gas control system: This is an important part of industrial exhaust gas treatment system for monitoring and controlling exhaust gas quality. This system consists of measuring and sensing devices to monitor parameters such as pollution gas concentration, exhaust gas flow and other parameters. Data from the exhaust gas control system can be used to adjust treatment processes and ensure compliance with environmental regulations.
The technologies and components mentioned above are just some common examples and do not cover all methods and components that can be used in an exhaust gas treatment system.
