Steam purging
Thread Content
For steam purging of oil tank trucks, how is the steam consumption calculated?
This depends on the principle of steam purging. There are two concepts related to using steam for purging: one is to use steam for heating in order to evaporate the residual liquid ； Another method is to use steam to heat and dissolve, thereby removing the degreasing solution. Calorie calculation is done based on different conditions. This is also related to changes in atmospheric temperature. The reference book \"Principles of Chemical Engineering\" is recommended for reference.
Hello, a tank truck needs to have its contents replaced; first, the existing material is displaced using nitrogen, and then it is purged with steam. How much 99.5% nitrogen is required for this tank? How much steam?
