Heat exchange between Hot Water and Liquified Petrolium Gas
I want to have a heat exchange between Hot Water and Liquified Petrolium Gas (LPG: 60% propane and 40% butane) to vaporize LPG which is liquid state before heat transfer. Can anyone tell me how it works in reality? What is need of vaporizing it when it can be naturally vaporized? What is the fundamentals to use this?
Please guide me.
