Essential Expertise for Process Gas Compressors
Nalco treats 90% of the treated compressors in North America. Still, this is a growing industry within the ethylene plant. Ten years ago, one-third of the compressors in the world were treated with a specialty chemical like our Comptrene program. Today, half of the compressors are treated, and the number continues to grow as ethylene producers look for opportunity feedstocks and run lighter feedslates.
The knowledge we’ve gained by treating the majority of compressors over the years has allowed us to create unbeatable chemistries and monitoring tools, including CompTrack. CompTrack™ software allows us to compensate for water addition and compare actual polytropic efficiency versus design.
