A resounding “yes” for Alfa Laval's Compabloc

Alfa Laval's Compabloc heat exchanger looked like a perfect choice when Monómeros Colombo Venezolanos, a leader in the Andean agrochemicaland petrochemical industry, needed to replace its outdated and unreliable Cascade coolers. But could Compabloc really be counted on, they wondered? The answer was a resounding “yes."

“Our relationship with Alfa Laval began when we purchased one Compabloc as a test pilot. Today we have 13 Compablocs that meet the total heat exchanger requirements of the entire oxy absorption section of our plant. The efficiency proportion, compared to the Cascade Coolers we used to use is 5 to 1,” says, Edward Moscoso Uribe, Manager of the Chemical Engineering Group of Monómeros.


Thirteen Compablocs used as nitric acid coolers at the Monómeros Nitric acid plant in Colombia.

Thanks to excellent performance and low maintenance levels (less than once per year), productivity rates have increased on average by 2 tons per day. And absorption efficiency rose between 0.5 to 1%, which has resulted in savings on energy consumption.
