The charge gas compressor is the heart of an ethylene plant. Fouling in a compressor directly threatens the plant’s overall run length. A decline in polytropic efficiency due to fouling can cost producers millions of dollars in terms of increased energy consumption, reduced throughput and lower ethylene yield. Corrosion in a charge gas compressor and its associated interstage coolers also compromises the unit integrity and reliability.  
 
To combat fouling and corrosion issues in a compressor train, Nalco Water offers:

• Compressor Antifoulants
  With close to 100 applications globally, Nalco Water antifoulant technology has helped global customers maintain top notch compressor performances over the past 30 years.

• Corrosion Inhibitor
  Nalco Water formulates its corrosion inhibitors specifically for compressor applications.

• Industry Benchmarking
  Our unique position as a leading solutions provider for compressor treatment allows us to benchmark global compressor performance with our proprietary compressor fouling index.

• Comptrack^TM Compressor Efficiency Monitoring Software
  Our Comptrack software compensates for water addition in its polytropic efficiency calculation and compares actual efficiency versus design.
