Abstracts: This invention about cooling tower. Cooling towers are heat removal devices used to transfer process waste heat to the atmosphere We had done our experiment at the “NIRMA LIMITED”. This place is equipped with two chillers with several pumps and four cooling towers. These units are responsible for processing and distributing the cold water used for refrigeration purposes throughout the all unit. In petrochemical based industry the use of oil and other liquid fuels is Mandatory. Direct type cooling tower is used in industry. Direct type cooling tower is always connected with distillation plant. So significant amount of oil is wasted. There is no reuse of this oil. It affects the cooling tower. Its heat exchange rate is decreased and other problems like scaling, fouling, corrosion will take place. So, for the reuse of this oil one can use oil separator machine in hot well. It is very cheap, requires less space, Very remote. It completely reduces human effort. This is very speedy way without chemical process and no heating is required. We Calculated the Range, Approach, Effectiveness and Efficiency. Before Implementation we calculate the efficiency of the cooling tower is 72%. After separate the oil from water we again calculate the efficiency of cooling tower is 73.07%. After Implement calculated efficiency is greater then the efficiency of without Implement.
