Investigation of compressed air losses on production cost for Mosul dairy factor

Abstract

A realistic field study was conducted on compressed air production stations in the Mosul Dairy Factory / Iraq, to determine the quantities of field losses resulting from the production of compressed air in the factory, and to determine the effect inlet temperature, pressure ratio, electric motor and leakage in the production line on the production cost, as all data were taken from the factory, and preparing a mathematical program to find and calculate the leaks in the compressed air in all parts of the factory production line. In addition to that the total cost of the compressed air losses during the production line was calculated. The results were listed in the form of quadrants that determined the relationship of the variables to losses in the production line. The typical lifetime compressed air costs in the year had been calculated and the percentage of each of the previous effects in the calculation of the saved cost, the results shows that the amount of the leakage, electric motor efficiency, intake temperature, and the reducing of setting pressure is about 16%, 54%, 25% and 5% respectively. This work leads us to another future work in which how to address these losses in compressed air in the factory production line and work to reduce them by technical means in order to reduce the cost wasted due to these losses.
