Abstract: Shortcomings and deficiencies existed in conventional rapid evaluation method for thermal potential in traditional refinery. A rapid evaluation method for refinery low-temperature heat potential based on modified circulating water was established by introducing the factors of the circulating water, energy efficiency. Data from 12 refineries were calculated. The deviations of the method were deternined. The results prove the superiority of the method for evaluation of refinery low-temperature heat potential. The rapid method is further verified when the low temperature heat potential coefficient of a typical refinery was calculated.
