Two power plants, one in Peru and one in the Caribbean, faced the same issue: fouled aero-condensersd ineffective cleaning methods. Both relied solely on traditional water-based cleaning and sought an a more effective solution. CTP Environment introduced DECAMEX® at both sites.

The Challenge

Fouling on the aero-condensers at both facilities reduced thermal performance and increased turbine backpressure, which directly impacted operational efficiency. Water-based cleaning, their standard method, had significant drawbacks:

  • High water consumption
  • Effluent management requirements
  • The need to protect motors and electrical components from moisture during each cleaning.

Neither plant had used dry-chemical cleaning, which offers superior results compared to their previous methods.

The Solution

CTP introduced its proprietary DECAMEX® dry chemical cleaning process at both facilities. This 100% dry application is designed for aero-condensers and air-cooled systems. The process uses no water, produces no effluent, and removes the need to protect motors or sensitive electrical equipment during cleaning.

CTP mobilized teams to both sites promptly and completed the cleaning with minimal disruption to plant operations. The dry application penetrated deep into the fin bundles, thoroughly and efficiently removing fouling deposits.

The Results

Results at both power plants exceeded expectations. Turbine exhaust pressure decreased by approximately 10% after DECAMEX® cleaning, directly reflecting improved condensation and overall plant efficiency.

Thermal performance improved immediately at both sites, with no water handling, no waste, and no disruption to operations. Both clients appreciated the process’s simplicity, speed, and measurable performance gains.

For CTP, these projects confirmed DECAMEX®’s strong potential in the South American and Caribbean and woldwide in power generation sectors and marked the start of broader regional expansion.
