Abstract: Decreasing storage temperature of oil products can elongate its storage period.Oil products temperature at cavern tankfarm and the tankfarm with earth covered are basically at local mean annual temperature.Results show that the optimal storage temperature of oil products is at 16~20℃.Based on temperature rang for oil products storage specified in the standard, research on storage temperature of abovegrcund steel tanks distributed in domestic 6 cities is carried out.Under the conditions of different weather, refrigeration form, air conditioning method, accumulation of cold way or complex method can be utilized to meet the needs of long-term storage of oil products in controlling storage temperature.When temperature of inlet oil products is higher, accumulation of cold way should be given preference in order to store oil products in aboveground steel tank.
