Abstract—KOGAS (Korea Gas Corporation) has two types of vaporizer to regasify LNG (Liquefied Natural Gas), which are ORVs (Open Rack Vaporizers) and SCVs (Submerged Combustion Vaporizers). Recently, KOGAS has been undergoing difficulties to additionally construct ORVs and SCVs due to environmental issues. So, KOGAS is considering eco-friendly vaporizers, which have never been experienced in the past, not to use seawater. AAV (Ambient Air Vaporizer) is a strong candidate for a clean environment. Hence, this work is to investigate its possibility for LNG import terminals of KOGAS in South Korea. For practical application of AAV, a feasibility study was carried out with candidate vaporizers. KAAV (KOGAS-type Ambient Air Vaporizer) is revealed as more effective than other vaporizers.
