Liquid Ethane Mother and Child Tank
The liquid ethane mother and child tank refers to a storage tank composed of multiple child tanks containing LNG arranged in parallel and placed within a mother tank filled with insulating material. It is typically constructed to meet large volume and pressurized storage requirements, and is commonly used in medium to large-scale LNG vaporization stations (1000m³ to 10000m³ storage capacity).
Product Details
Product Structure
The LNG mother and child tank consists of multiple child tanks, a mother tank, and corresponding process pipelines, valves, instruments, etc.
Child Tank: Serving as the main container for low-temperature media, it is made of austenitic stainless steel S30408 material; the child tank has a vertical cylindrical leg structure, and depending on the volume, 4, 7, or 10 child tanks are interconnected through pipelines to connect all or grouped gas and liquid phases.
Mother Tank: Serving as the protective shell of the insulation system, it is usually made of Q345R/16MnDR material. The mother tank accommodates all child tanks and uses powder accumulation insulation to maintain cold storage, ensuring minimal vaporization of the stored medium.
Main Technical Parameters
Storage Medium: LNG
Working Pressure: 0.2MPa~1.6MPa
