What Does a Cargo Compressor Actually Do? | LPG Reliquefaction Explained | Maritime Made Simple

In Video 2 of Maritime Made Simple, we take a closer look at one of the most important components of an LPG reliquefaction system — the Cargo Compressor. In the previous video, we understood why a reliquefaction plant is needed. Now we follow the vapour and understand what the compressor actually does. 🔹 In this video, we explain: ⚓ What enters the cargo compressor ⚙️ How the compressor draws vapour from the cargo tank 🔄 What happens during compression 📈 Why pressure increases 🌡️ Why temperature increases during compression 🔥 How compression prepares the vapour for condensation ❄️ What happens next in the condenser 🔽 The role of the expansion valve 💧 How cold liquid is returned to the cargo tank 🔄 The complete reliquefaction cycle We also use simple real-life analogies and molecular-level visuals to make the process easier to understand. 🔑 The complete concept: VAPOUR → COMPRESS → CONDENSE → EXPAND → SPRAY → CONDENSE → REPEAT The important idea is that the reliquefaction plant does not stop heat from entering the cargo tank. It manages the effect of that heat by continuously removing vapour, condensing it and returning cold liquid to the cargo tank. ⚓ Maritime Made Simple Making complex maritime, cargo and gas-carrier concepts easier to understand — one concept at a time.
