ANALYSIS ON FIRE COOLING EFFECT OF CRUDE OIL TANK
Traditional crude oil tank design methods presented in various codes are usually based on insulation, especially in China. However, these two aspects may be contradictory since the insulation of tank wall may prevent the wall cooling. Once the tank fire, if the cooling water can not effectively play a cooling role, the heat radiation from the fire could threaten nearby tank. The design of insulation for crude oil tank should account for both fire cooling and insulation. In insulation, the issues relate to prevent heat loss as possible, and make oil temperature maintain at a certain range. Inadequate flow of cooling water often results in the nearby tank absorbing a large number of radiant heats, and fire risk greatly increased. Consequently, in order to e-liminate hidden dangers to protect the safety of tank group, the cooling water flow and the thermal resistance of insulation should be considered together. In recent years, a number of projects have been funded to develop some crude oil reserve bases in China. In this work the different water requirement between Chinese codes and others is pointed out firstly. Then the control factors of the cooling water flow and the thermal resistance of insulation were examined. Then calculational model of fire cooling water and insulation on crude oil tank is built. Obviously the insulation maybe reduce fire cooling impact on crude oil tank. At last, a rude water requiremen results and future work are discussed. Based on this paper, the tank manager can be aware of the potential fire threat tank group and able to choose in advance to do something for prevention and remediation. It is believed that the approach to calculational model of fire cooling and insulation presented in this paper may lay the initial basis for tank fire prevention.
