Industry Cooling Challenges in Chemical Production
1. High-Temperature Continuous Operation
Chemical processes typically run 24/7 under continuous heat loads. Equipment such as:
Reaction vessels
Distillation towers
Condensers
require stable thermal control.
Key issues:
Cooling efficiency drops significantly in ambient temperatures above 40°C
Traditional systems suffer 15%–30% performance degradation during summer peaks
Temperature fluctuations directly impact reaction stability and yield consistency
2. Corrosive Operating Environment & Safety Risks
Chemical plants often involve exposure to:
Sulfuric acid (H₂SO₄)
Hydrochloric acid (HCl)
Organic solvents and reactive gases
Common failures in conventional systems:
Corrosion-induced leakage
Seal degradation
Heat exchanger fouling
High failure rate within 3 years (up to 35% in severe environments)
Even minor leakage in cooling circuits can lead to:
Process interruption
Chemical contamination risks
Safety incidents and compliance violations
3. Energy Consumption & Environmental Compliance Pressure
Cooling systems represent a significant share of plant operating costs:
18%–25% of total electricity consumption in chemical facilities
Strict compliance required under energy efficiency regulations (e.g., GB 19576-2021)
Wastewater discharge must meet stringent COD limits (≤ 50 mg/L in many regions)
Therefore, energy efficiency and system optimization are critical investment drivers.
