Although the company monitors their overall loss of phosphorus pentoxide, lack of distribution of the loss at main leak points hinders the structured corrective actions. The company was recommended to practice the qualitative and quantitative monitoring of losses, following the structure of cost centers defined within the MFCA, so as to define the focus areas of option generation, and develop structured saving measures.
Adjusting the hot air temperature, that is used for drying, to the maximum allowable temperature for maintaining the product quality resulted in reduction of the air flow, and consequently improved the thermal efficiency, and saved on energy.
In a basic chemicals production facility, the use of larger packaging sizes saved on material losses associated to spillage, and increased the productivity as the chane over time is reduced.
This measure illustrates the wasteheat recovery from the chimney, where the exhaust gases were vented without any utilization. Installation of a heat exchanger at the chimney, together with adequate filteration system facilitated to benefit from the waste heat to preheat the combustion air, and save on energy.
Energy mapping in a basic chemicals production company indicated that the motors are not operating at their maximum load due to low production capacity. Equipping the motors with electronic speed controllers facilitate optimising the motors performance, and save on energy.
