Gas to Liquid Heat Exchanger

Fume, VOC Gas Condensation, Heat Exchanger
Low pressure loss. Applicable materials: 304 /316L / 310 / SMO254 / C276 / Ni201 
Max. flow up to 50.000 Nm3/h

Method principle: Using patented, specially designed heat and corrosion-resistant metal plates as a medium, heat exchange takes place leveraging density differentials between water (vapor) and gas.

Sulfides or corrosive substances in high-temperature gases can also be extracted via condensation in the condensing process and drained in liquid form.

Meanwhile, high-temperature gas is cooled down to harmless low-temperature and discharged into the atmosphere for protecting the ozone layer; thereby eliminating fines relating to infringement of environmental statutes and preventing the corporate image from being impaired.

At the same time, cooling water at the low-temperature side is warmed up after getting in contact with high-temperature gas; where heat can be recycled for re-use based on customer needs or led into a lithium bromide air conditioning system for achieving energy saving through using waste heat.



Taiwan SRP Gas to Liquid Heat Exchanger - Introduction

Gas-Liquid and Steam-Gas Heat Exchangers manufactured by Taiwan SRP Inc. are suitable for the organic solvent recycling process of high-flow low-pressure gases.

Taiwan SRP Inc. Gas-(Steam-)Liquid Heat Exchangers differ from traditional fin or metal tube Heat Exchangers. Our newly developed Gas-(Steam-)Liquid Heat Exchanger is designed with specially patterned plates for absorbing and releasing latent heat during the phase transformation when a gas (steam) contacts a liquid, thereby increasing heat transfer and achieving low pressure loss (0-1000pa) and excellent heat exchange effect.

Product is of respective single metal design (ss304/316L, SMO254 ~ C276), provision of versatile materials significantly increases the corrosion resistance of the product. Specially punched and laser-welded plates are easy to clean and replace. Features such as high efficiency, lightweight, and small footprint also reduce customer costs derived from pipeline alterations. An automatic cleaning system can also be designed according to the operating environments of the customer, thereby prolonging the service lifespan of the product.

Taiwan SRP Inc. is the only supplier in Taiwan that provides Plate-type Gas-(Steam-)Liquid Heat Exchangers. The structure design of internal modules can be tailor-made to meet customer requirements, just as agile as building blocks; expansions can also be made afterward as required.
SRP uses different structure materials in the design of module blocks and shells for different gas (steam) applications to liquid heat exchange, such as air condenser, heater, desulfurization post processer, boiler tail gas recycling, exhaust heat recycling, and corrosive gas prevention. Temperatures can be as high as 800℃.


Features of SRP Gas to Liquid Heat Exchangers

  1. Single metal seal
  2. Patented plate and laser welding; welds are of tight structure without miss points.
  3. Material can be of SS304/ SS316L/ SS317/ SS310/ SS904/ SMO254/ C276.
  4. Takes in all kinds of gases, including heavily polluted exhaust, high-temperature white fume, sulfur-containing tail gas, and toxic gas.
  5. Desulfurization process of stack tail gas
  6. High resistance against corrosion, long service lifespan. (Corrosion-resistant material)
  7. Modular easy to clean Product Design.
  8. Maximum handling capacity up to 1,000,000 m³/H
  9. Low design pressure loss: 1 Pa ~ 1000 Pa
  10. Water side (Steam side) maximum allowable working pressure: 50 Bar.

Patented laser-welded channel plates as heat transfer elements. Special channel structure allows even distribution of both gas and liquid when they come into contact with each other in the channel. Gas flow can be smooth and stagnation-free; eliminating gas stagnation and channel clogging problems often seen in traditional air condition systems.

Sealed Metal Housing for compact and hermetic product structure.


Customer Benefits through the use of SRP Gas to Liquid Heat Exchangers

  • Low pressure loss
  • Resolve environmental pollution issues regarding exhaust gas and white fume; comply with statutory regulations
  • Reduce air-pollution control fee regarding discharge of SOX gases.
  • Recycle gas for energy re-use. Power saving for the factory.
  • Low scale formation and corrosion. Long service lifespan. Lowers purchase costs.
  • Easy cleaning and maintenance. Ensures production line efficiency via stop-less operation.
  • Lowers power consumption. Prolongs system lifespan. Reduces toxic emission. 
  • Competitive production cost
  • Swift maintenance and after-sales service
  • Modular design of product for high flexibility.

While environmental protection and green energy topics gain great concerns gradually and relevant legislation becomes more comprehensive, the discharge of corrosive and SOX gases in white fume exhaust from large scale stacks, sulfur containing tail gases, boiler exhausts, and heavy oil combustion processes has created new issues in the industrial field.

For Gas (Steam) to Liquid Heat Exchanger products, Taiwan SRP Inc. offers applicable materials based on customer site conditions and flow demands. Users only need to clean as scheduled for achieving the spirit of a sustainable environment: one machine for a lifetime, renew energy from recycled heat. The recycled heat can also be used on the livelihood water of the factory or for secondary use of the site.


Applications of SRP Gas-Liquid Heat Exchanger

  • Oil and gas industry
  • petrochemical industry
  • Chemical Industry
  • Incinerator industrial
  • Energy Industry
  • food industry

(1) High-temperature gas is cooled down, used for heating, or condensed before discharge.
(2) Exchange waste heat in the gas for energy saving
(3) Treat high-temperature gas before discharging it to the atmosphere for the protection of the ozone layer.


SRP Gas to Liquid Heat Exchanger – Customer success stories and case studies

Gas-Liquid Heat Exchanger for exhaust treatment of fried food industry in Taiwan


Potato chip frying pot of the food industry releases a large amount of fumes into the atmosphere during the production; the fume damages our ozone layer and causes large fines.

Application Solutions

After installing our Gas-liquid Heat Exchanger, the existing high-temperature fume of frying oil is led through the Heat Exchanger. It warms up the cooling water, which becomes the heat source of a lithium bromide air conditioner, thereby achieving the goal of heat recovery and energy saving. At the same time, the high-temperature fume becomes low-temperature clean gas after the heat exchanging process. It is discharged into atmosphere, thereby eliminating issues caused by the direct discharge of the hazardous gas.

Considering sanitation requirements of the food industry, our product is designed with an automatic cleaning system, which will activate the reverse cleaning system at night when the system stops operation and remove stains of the daily frying oil adhered inside the heat exchanger channel. A comprehensive maintenance plan prolongs product lifespan; it also compensates for the hard-to-clean shortcoming of this type of product often seen in the past.

Material: 316L full laser-welded stainless steel. Port Diameter: DN400. Due to site limitations, special design is adapted for optimal use of space. 

Working Temperature: Primary side, Fume, 93.5℃~70℃; secondary side, Water, 58℃-80℃.

  • Compared to traditional Heat Exchanger, lighter weight and smaller volume for space-saving and easy installation.
