Industries such as manufacturing, chemical processing, oil and gas refining, and oil rigs rely on cooling towers and other equipment to cool the water necessary for their operations. With increasing environmental regulations and evolving market conditions, these industries are seeking advanced cooling technologies to meet their demands.
In the oil and gas sector, many of the cooling towers currently in use were built as part of the original plant construction and are approaching the end of their service lives. To meet current production needs and industry standards, these towers need to be upgraded or replaced with more efficient products, and better long-term maintenance plans must be established.
A High-Pressure Mist Cooling system is a highly effective cooling solution that utilizes the evaporative cycle by atomizing water to absorb heat and achieve a cooling effect. 100kg of water in the evaporation process can absorb 68kw of heat from the air. With our extensive industry experience and market knowledge, we offer a wide range of High-Pressure Mist Cooling Fog Systems to our valued customers.
The High-Pressure Oil Mist Lubrication System is highly acclaimed in the market due to its excellent performance, offering several advantages such as
- Minimizing damage to manufacturing equipment and products caused by Electrostatic Discharge (ESD).
- Improved product quality leading to increased revenue.
- Enhanced productivity resulting from reduced employee absenteeism.
- Improved employee health and comfort in the workplace.
Cooling Tower Operation and Types
Cooling towers play a vital role in reducing the temperature of water in industrial processes by allowing it to come into contact with air. The process involves pumping the water through pipes and spraying it through nozzles onto banks of heat transfer material, known as fill. The water is slowed down as it moves through the cooling tower and is exposed to as much water surface area as possible for maximum air-water contact. An electric motor-driven fan pulls air through the tower and as the air and water meet, a small amount of water is evaporated, resulting in a cooling effect.
After the water is cooled, it is pumped back to the processing equipment where it absorbs heat and is returned to the cooling tower to be cooled again.
There are various types of cooling towers suitable for different industrial cooling needs. Field-erected towers (FEP) are constructed on-site, designed for large heat loads, and customized to address specific applications. They are suitable for power and heavy industrial uses and are commonly found in wastewater treatment plants and chemical processing plants.
Factory-assembled towers (FAP) are constructed in modules at a manufacturing facility and then shipped to the processing plant in as few pieces as possible for final assembly. They are available in many cooling capacities and box sizes and come with standardized mechanical and structural components.
For wastewater treatment plants and chemical processing plants, open-circuit wet cooling towers combined with shell-and-tube or plate-and-frame heat exchangers provide a cost-effective method of heat rejection. These towers are designed to wet bulb temperature and can cool water to a lower temperature than some other types of towers. However, other methods are also employed by these facilities to achieve cooling.
Air-Cooled Heat Exchangers
Air-cooled heat exchangers are an alternative cooling technology to evaporative cooling towers. While evaporative cooling towers use heat move fill to effectively distribute hot interaction water and increase its surface area for cooling, air-cooled heat exchangers utilize only airflow to cool hydrocarbon products and other fluids in tubes.
One advantage of air-cooled heat exchangers is that they can handle high heat loads common in oil-and-gas and chemical processes, require infrequent maintenance, and do not evaporate water for cooling. This makes them a suitable option for situations where water is scarce, unavailable, or expensive.
In contrast to evaporative cooling towers, air-cooled heat exchangers do not require relatively clean water to operate effectively. Water with lower quality, containing particles and debris, may obstruct the fill and reduce performance.
Air-cooled heat exchangers work well for higher-temperature hydrocarbon applications and are commonly used by the oil-and-gas industry, as they do not require water or water chemistry maintenance and do not create the vapor plume of evaporative towers. However, they are designed to dry bulb temperature and cannot cool water or interaction liquids to temperatures as low as wet cooling towers.
Chemical plants may also use other specific heat exchangers, such as evaporative condensers and closed-circuit liquid coolers, to cool processes and fluids.
