Fluid Cuts Processor's Batch Time in Half
The low temperature fluid, Paratherm CR, was tried out by Bedoukian Research Inc., Danbury, Conn., a producer of fragrances, insect pheromones, food flavorings, pharmaceuticals and agricultural chemical products. As the company's production volumes and product lines grew, lower processing temperatures became a priority, according to the chemical maker. Bedoukian said that the fluid from Paratherm Corp., Conshohocken, Pa., let it realize a 200 percent increase in throughput, with higher purity for the larger-yield batches.
According to Bedoukian, Paratherm CR quickly proved to be a far more efficient at reducing temperatures from chemical reactions than any heat transfer fluid the company had previously used. "We were looking for a long time to find a thermal fluid that would do what we need it to do," general manager Greg Pignone said. "This is it."
Liquid nitrogen chills the Paratherm CR fluid before it circulates through the heat transfer jackets surrounding the reactors, which have capacities ranging from 50 to 200 gal. The fluid removes heat generated by chemical reactions that occur during manufacturing processes.
Since the changeover, there have been larger yield batches. In addition, production time has been reduced by more than 50 percent.
"We are able to run some of our cooled chemical reactions twice as fast now," president Robert Bedoukian said. "We can run at much lower temperatures than before with better heat transfer. This opens the door for us to produce custom syntheses that we couldn't have attempted before."
