Cleaning Heat Exchanger During Operation

Desediment of heat exchanger is common in industry and lot’ s of efforts have been done. In this article (essay) it has been studied about decreasing of sediment on-line way and it’s advantage in compare to off-line way. and also if has been studied about ammonia units air compressor problem in petrochemical co in khorasan that is resulted from sediment of heat exchanger of third stage, with usage of coloridric asid %5 and flomate matter %2 on line by preventing from stop of ammonia units and also urah units chemical washing of E-2143 exchanger activity, caused decreasing of compressor vibration, decreasing of exchanger’s water’s temperature, decreasing of air outlet air temperature of exchanger, increasing of cool water flowing and deduction and cost saving, and is finished successfully.
