Air Pollution Prevention System

 

Air Pollution Prevention System

This system removes or reduces air pollutants emitted from industrial sites due to
rapid industrialization and complex bad odors of VOCs, NOx, and SOx, that are harmful to the human body..

Combustion System

  • 01 Regenerative Thermal Oxidizer (RTO)

    This is a high-efficiency, energy-saving facility that treats VOCs and bad odor gases emitted in manufacturing by using combustion (oxidization) at high temperature, and recovers heat from combustion using heat storage material. It is usually applied to most of VOCs (e.g., print factories, petrochemistry, semiconductors, adhesive tape, medicine, painting, food manufacturing, wastewater treatment, and electric wires) and facilities that generate bad organic odor .

  • 02 Regenerative Catalytic Oxidizer (RCO) and Catalytic Thermal Oxidizer (CTO)

    This system, which reduces the energy needed for VOCs combustion (oxidation) using a catalyst, is very economical because only about 30~40% of the energy needed for direct combustion is used. It is usually applied to VOCs (e.g., print factories, petrochemistry, semiconductors, adhesive tape, medicine, painting, food manufacturing, wastewater treatment, and electric wires) and facilities that generate bad organic odor.

oncentration System

  • 01 Concentrated Regenerative Thermal Oxidizer (CRTO)

    This system adsorbs low and medium concentrations of VOCs with high wind volume using zeolite. By desorbing them into high temperature gases with low wind volume, it treats high concentration gases with a combustion facility. It has a high energy saving effect because operation without fuel is possible with VOCs concentration. It is usually applied to printing, painting, coating, washing , oil refining, etc.

MW System

  • 01 Microwave VOCs Removal Facilities

    It adsorbs VOCs using adsorbents and desorbs them by irradiating with microwaves. The desorbed VOCs are concentrated at a maximum 1/40 of low wind volume and treated with catalytic oxidation. When treated at low concentration and wind volume, energy savings over 30% are possible compared to existing facilities. It is usually applied to printing, painting, coating, washing and oil refining.

De-NOx System

  • 01 SCR

    This is a system which proceeds with effective NOx reduction reaction at relatively low temperatures of 250-400℃ by spraying reducing agents (ammonia, etc.) on flue gas and passing it through a catalytic layer. It is usually applied to boilers, power generation facilities, waste water, waste gas, waste incineration facilities, etc.

  • 02 SNCR

    This is a system which proceeds with effective NOx reduction reaction at relatively low temperatures of 850-1,100℃ by spraying reducing agents (ammonia, etc.) on flue gas and passing it through a combustion chamber without a catalyst. It is usually applied to boilers, power generation facilities, waste water, waste gas, waste incineration facilities, etc.

Complex Bad Odor and VOCs Removal System

  • 01 MDS

    This is a system that can be installed as a local ventilator at sites where harmful gases are leaked in an emergency or pollution gases occur during manufacturing process. Operation is simple, and more than 95% of harmful gases can be treated in a short time. It is usually applied in laboratories or places inside factories where harmful substances are emitted.

  • 02 Adsorption Equipment

    his equipment removes VOCs through physical adsorption at 50℃ or below using porous adsorbents such as activated carbon. Also, a selective chemical adsorbent application design that can reduce the index of complex bad odor gases such as hydrogen sulfide, ammonia, and aldehyde gas by more than 500 times is possible. It is usually applied to painting and adhesive manufacturing, paint manufacturing, food waste processing, livestock manure, sewage, waste water, biogas plants, etc.

  • 03 Absorption Equipment

    This system treats bad odor gases emitted during manufacturing process by putting them into contact with absorbent solution. The operation of the system is based on the particular properties of such gases: the bad odors are dissolved well in the solution; and chemical reaction occurs when they are put into contact with the solution. It is mainly used in facilities that generate bad odor, such as chemical fertilizer manufacturing facilities and kilns.
