Checking the steam network at a carbonated beverage production facility revealed that the steam condensate is not recovered, leading to loss of water and energy. Installing a condensate recovery network is a feasible alternative to conserve natural resources.
A carbonated drinks facility used diesel fuel to operate its boiler despite it was connected to the natural gas grid. Replacing the boiler’s burner with one that can fire natural gas, and increasing the contracted capacity for natural gas was found as a feasible measure to maintain economic benefits and reduce the pollution load.
A milk and beverage company suffered from repeated power outages, thus relied on diesel generators to maintain production availability. The triggers for the generators were not optimized to recharge after short power outages, leading to occasional cuts, forcing CIP to start. Adjusting the triggers of the generators shall eliminate untimely shutdown of equipment.
Floor washing in a dairy was practiced through open end hoses, which operators occassionally leave running instead of closing the taps. Suggested measures include utilization of pressureized cleaners as well as equipping the hoses with spray guns to provide high pressure water suitable for cleaning and to control the water flow.
Water mapping in a textile company revealed several opportunities to conserve on water and thermal energy through process optimisation and energy efficient design.
The existing airconditioning unit is not capable to keep needed temperature and humidity in the packaging room leading to high amount of rejected chocolate products and should be replaced by a central Air Handling Unit to achieve the desirable parameters.
A beverage and juice manufacturing company had an oversized, obselete design compressor running at low load factor. This caused excess energy consumption. Replacing the compressor from a piston type compressor to a smaller size rotary-screw type compressor shall increase the efficiency of the compressor, and reduce the unload time which is a waste of energy.
Measurements of surface temperature within the steam network revealed lack of maintenance for the network, particularly in the pipes insulation. This resulted in overconsumption of fuel in the boiler. Fixing the insulation shall increase the boiler efficeincy, and reduce the energy consumption.
