Heat exchanger cools granular fertilizer
A water-cooled, plate-coil heat exchanger effectively cools a fertilizer producer's hot, granulated urea, preventing caking in storage and production decreases.
Since 1976, a fertilizer producer in Alberta, Canada, has manufactured granulated urea. To manufacture the urea, ammonia and carbon dioxide are combined using a complex process resulting in a urea solution that is evaporated to a urea melt. The melt is sprayed into one of four heated granulating drums; the drum revolves slowly, like a rotary kiln, and has a design capacity of 375 short tons per day. After granulation, the urea is screened.
