25KPa LNG Regasification Terminal Cryogenic Storage Tanks Dragon Crown Second Phase
Terminal Station 20,000m3 Cryogenic Ethylene Tank (Dragon Crown second phase)
Brief Introduction of Project
In January 2013, we undertook the 20,000m3 cryogenic Ethylene storage project (2nd phase) for Nanjing Crown Dragon Liquid Chemical Co., Ltd. It's the second time cooperation with Nanjing Longxiang after safety and stable running of the first project since 2007.
