How is LPG maintained liquid at ambient temperature in pressurized ships?
Direct Answer
Option A: High pressure inside Type C pressure vessel tanks (~18 bar)
Type C pressure vessels are designed to carry LPG at ambient temperatures by maintaining high internal pressures, typically around 18 bar. This pressure keeps the cargo in a liquid state without the need for complex refrigeration plants, as defined by the IGC Code's requirements for independent tank design and pressure containment.
