Our Closed Cooling Tower are widly used in the industry of petroleum, chemical industry, pharmaceutical industry, coal, power industry, steel and other fields. We have cross flow, counter flow, combined flow Cooling tower and we can offer customed service of color, dimension, etc..
Cooling Tower Used in Natrual Gas Plant
In a natural gas plant, a closed cooling tower serves a crucial function in maintaining optimal operating temperatures for various equipment and processes. Closed cooling towers are utilized to remove excess heat generated during the production and processing of natural gas.
These towers work by circulating a closed loop of water or another coolant through a series of heat exchange coils. As the hot process water flows through the coils, heat is transferred to the surrounding air through evaporation and convection. The cooled water is then recirculated back into the system to absorb more heat, while the warm air is discharged from the tower.
Closed cooling towers offer several advantages in natural gas plants, including
1. efficient heat transfer,
2.reduced water consumption compared to open cooling systems,
3.minimized environmental impact by preventing water loss through evaporation.
4. Additionally, closed systems help maintain water quality by isolating it from external contaminants, ensuring reliable operation and prolonging equipment lifespan in the demanding conditions of a natural gas plant.

Main Components of Cooling tower used in natural gas plant
1. HEAT TRANSFER COIL
A. Each group of coil tubes is arranged with consistent slope, and the slope direction same with the water flow direction, east to facilitate water discharge from the pipe.
B. Bracket for the coil is made by welded sectional material, and all processing technologies meet China National Metal Welding Workmanship Requirements & Standard. The cleaning and coating workmanship of the coil bracket surface same to the evaporative condenser bracket.
C. Designed pressure is 2.0MPa, tubes in each group go through previewing and pressure test, and then to be assembled after getting through quality test. Test in the water with pressure 2.5MPa after assembled, to ensure its high performance in pressure resistance.
D. Heat exchange coil is made of Galvanized steel or stainless steel.
2. AXIAL FAN AND PUMP MOTOR WITH EXD EXPLOSION-PROOF PROTECTION CERTIFICATE
The significance of an explosion-proof fan motor in the cooling tower of a natural gas plant cannot be overstated. Given the potential presence of flammable gases or vapors in the environment of a natural gas plant, it is essential for cooling towers and associated equipment to possess explosion-proof capabilities to ensure workplace safety. An explosion-proof fan motor enables safe operation in potentially explosive environments, reducing potential safety risks stemming from motor failures. Therefore, the use of cooling towers equipped with explosion-proof fan motors in natural gas plants enhances workplace safety, ensuring the stability and reliability of production processes.
5. SPRAY WATER DISTRIBUTION SYSTEM
A. The fill is one of the most important part of cooling tower, PVC heating exchange layer more effective to cool the water temperature by enlarge the evaporating surface.
B. The PVC fill are produced by total automatic controlled high-speed blister forming machine in my workshop, better and more quick shaping. Meanwhile, the machine ensures the consistency of all fillers, being glued to entire body with glue rate no less than 95%, the compressive strength ≥300Kg/M2. The fillers have large heat exchanging surface and minimum air resistance, more effective.
C. With special design, fill surface has good hydrophilicity, water absorptivity less than 0.015%. So more water film produced without splashing down. Water flowing rate less than 0.01%, more water saving, very suitable to Water stress region. Corrosion resistant, flame retardant, reinforced PVC packing, inflaming retarding oxygen index≥30. All raw material imported from South Asia to ensure the cooling tower fillers top quality and high performance
D. Drift eliminator: efficient water collection device is a standard part of evaporative condenser, which allows drift loss by circulating water less than 0.002%. Drift eliminator is made of corrosion-resistant modified PVC, Oxygen index of flame retardant≥30. Packet installed inside the unit, in order to access the internal water distribution system and other components.
6. Spray water distribution system
A. Spraying Pumps: The spraying pump special designed for evaporative condenser, with Siemens or WEG brand motors. With high flow, low head, high efficiency, low noise, low power and energy saving advance. Pump motor with protection class IP55, insulation class F.
B. Spraying Water Pipe: made of PVC, with flowing advantages: easy cold, high pressure resistance, anti-corrosion, and water resistant. All spraying manifolds are adopted removable type, easy to replace and clean.
C. Nozzle: ABS material injection molding nozzle basket type -2-efficiency provided by the well-known brand suppliers; Adopt bigger hole diameter nozzles to prevent from blocking, which has a large flow, no clogging, water distribution uniformity, etc; in the design of the nozzle so that the different positions of the cloth water flow deviation <5% of the entire water distribution system can guarantee 70% to 130% of the rated flow of water distribution uniformity.
E. Water level control system: the water level in spraying water tray is controlled by galvanized steel ball valve.
