This type of tank is used to store materials that are gaseous at normal temperatures and turn into liquids upon cooling and are stored as liquids at atmospheric pressure.HEDCO is now the leading company in Iran that has accomplished the engineering and construction of cryogenic storage tanks with the temperature range of up to -160 deg. C . This temperature range covers the following services:
- Butane (-0.5 deg. C)
- Ammonia (-33 deg. C)
- Propane (-42 deg. C)
- Propylene (-47 deg. C)
- Ethane (-88 deg. C)
- Ethylene (-103 deg. C)
HEDCO is able to design different types of Cryogenic tanks including:
- Single Containment
- Double Containment
- Full Containment
- Membrane Tank
HEDCO performs complete design of the Cryogenic Tanks including:
- Mechanical design
- Thermal design
- Boil off rate
- Insulation
- Foundation
- Frost heave
- Roll over
- Cool down
- In tank pump
The deliverables pertinent to this subject are a complete range required by as below:
- PID & PFD
- Design software for cryogenic storage tank (Mechanical design & thermal design)
- Conducting safety reviews such as HAZOP, SIL and Fault tree analysis
- Required specification ( material, insulation, …)
- Construction, inspection commissioning and operating procedures
The mechanical and thermal design of the tanks is guaranteed by HEDCO based on the similar requirements from vendors.
