In a fully refrigerated LPG carrier, at what temperature is propane typically carried at atmospheric pressure?
Direct Answer
Option B: 42°C
Propane has a boiling point of approximately -42°C at atmospheric pressure. Fully refrigerated LPG carriers utilize this physical property to maintain cargo in a liquid state at near-atmospheric pressure, requiring robust insulation and reliquefaction plants to manage boil-off gas effectively per IGC Code design standards.
