Focus Industry FOOD PROCESSING | 03/08 | CO2 O Air System Configuration Review There are three compressor rooms at Midwest Bakery: 1. The first room is the Buffer Compressor Room. This room contains one 100 hp oil flooded rotary screw compressor, one refrigerated dryer and one 400gallon tank. The air is discharged from the compressor through a 2" pipe and enters a wet 400-gallon storage tank. From the 400-gallon wet receiver, the air is filtered and enters the air dryer. After the dryer, the air is discharged to the plant through a 2" pipe that connects to the plant air system. The East Compressor Room contains one two-stage oil flooded rotary screw compressor, but air can also be fed from a small oil flooded rotary screw compressor downstairs. This room also contains one blower purge regenerative dryer and two 600-gallon tanks. Air flows from the downstairs compressor through a 2" pipe where it connects with 4" pipe from the twostage compressor. A 4" pipe connects the water cooled after cooler and the wet 600-gallon storage tank. The air flows in 4" pipe through a pre-filter and into the blower purge regenerative blower, then back out through an after filter and into a dry 600-gallon storage tank before connecting with a 3" pipe T and continuing on to the plant. The West Compressor Room contains five oil flooded rotary screw compressors, a blower purge regenerative desiccant air dryer and one 600gallon tank. The air flows through a 3" pipe from the rotary screw air compressors #1 and #2, compressor #3 begins with 4" pipe, and both compressors #4 and #5 have a 1.5" discharge. All five compressors feed a 4" main that flows to a wet 600-gallon storage tank. The air then continues through a 4" pipe and flows through a pre-filter before entering the purge regenerative blower. From the discharge of the dryer, air flows through an after filter in the 4" pipe before connecting to a 3" T in the plant. The first step to understanding your air system is to write out (or draw) a list of all the equipment and where the air flows from each air compressor. 2. kW Jim Timmersman and Power Supply Industries Inc. have many years of successful auditing experience in the food industry.
