Problem:
A large textile plant found that the energy they discharge after processing accounted for almost 45% of their total energy bill. Dunlop Design Engineering were appointed to determine which energy saving technologies should be installed by the company and which were the most cost effective to be used.

Solution:
After a detailed survey and subsequent analysis of their requirements, Dunlop Design Engineering concentrated on the energy that could be recovered from their waste water systems. The textile plant had been heating water from a cold water source. The cold water was heated before being used for the textile processing and then it was discharged after use into the drain. As this practice can normally equate to a range of 25% to 50% of the energy cost of the process, Dunlop recommended that they introduce a KEMCO Wastewater Heat Recovery System to capture the heat from the wastewater to preheat the incoming cold water.
The Kemco system uses specialised tubing in shell heat exchanges rather than the traditional plate heat exchanges, which can cause blocking and loss of thermal efficiency due to fouling. The tubular system is much more efficient than the plate heat exchange system and approximately 80% of the wastewater energy was recovered.

Saving:
In this particular case study in a large textile processing plant Dunlop Design Engineering found that a total of 2,957 kW of energy was being discharged. The total energy bill was £198,200 and the energy discharged costs the company £89,190 amounting to almost 45% of the total bill. The Climate Change Levy accounts for approximately 10% or £8,919 of this.
The system chosen has a lifetime of 10-15 yrs and payback is in less than 2 yrs. It is clear that in utilising these technologies it has had a significant impact on a company’s bottom line.
