ABSTRACT:
A method of storing a fluid product in a positive expulsion tank and subsequently expelling product therefrom, which prevents damage/failure of a resiliently deformable bladder, due to handling/transport forces exerted in the tank while exposed to a minimum design storage temperature.
The method includes the step of filling the product receiving cavity with the product at a filling temperature and at a volume at the filling temperature allowing the product to fill the product receiving cavity at the minimum design temperature while permitting the bladder to assume its as-fabricated configuration.
