Power Generation Systems
Geothermal Plants
KAF Cryogenics supplies separator tanks, accumulation tanks and N-Pentane tanks designed and manufactured in accordance with EN 13445, ASME (U Stamp) and AD 2000 Code standards, and in compliance with the EU Pressure Equipment Directive (2014/68/EU, PED). Tank size and anchoring are determined according to seismic and wind load calculations carried out to the relevant standards, and the support and leg design of each tank is arranged to allow convenient transportation. Surface finishing is completed with oven-dried, high-quality paint application, and each tank is verified through non-destructive inspection methods, including ultrasonic testing, penetrant testing and magnetic particle testing, in line with applicable standards.
In geothermal power generation plants, the heat-loaded fluid extracted from underground resources is first directed to the separator tank, where solid particles are separated from the process and the liquid and vapor phases are divided using the flash separation method. Accumulation tanks serve as pressurized liquid storage vessels used to meet interim steam or hot water storage needs across various industrial processes, geothermal power plants and hot water usage applications. N-Pentane tanks store the N-pentane organic working fluid used in binary-cycle (Organic Rankine Cycle, ORC) geothermal units, where heat from the separated brine vaporizes the working fluid to drive a turbine, as well as N-pentane storage for other industrial plant requirements.
Frequently Asked Questions
Which standards are the tanks manufactured to?
Separator, accumulation and N-Pentane tanks are manufactured in accordance with EN 13445, ASME (U Stamp) and AD 2000 Code standards, and comply with the EU Pressure Equipment Directive (2014/68/EU, PED).
How are tank size and anchoring determined?
Size and anchoring are selected according to seismic and wind load calculations carried out in line with the relevant standards, with support and leg design arranged for convenient transportation.
What quality checks are applied?
Each tank receives oven-dried, high-quality paint application and is inspected using non-destructive methods such as ultrasonic testing, penetrant testing and magnetic particle testing, in accordance with applicable standards.
What is a Separator Tank used for?
In geothermal power generation plants, the heat-loaded fluid from underground resources is directed to the separator tank, where solid particles are removed and the liquid and vapor phases are separated using the flash method.
What is an Accumulation Tank used for?
Accumulation tanks are pressurized liquid storage vessels used to meet interim steam or hot water storage needs in industrial processes, geothermal power plants and hot water usage applications.
What is an N-Pentane Tank used for?
N-Pentane tanks store the N-pentane organic working fluid used in binary-cycle (Organic Rankine Cycle, ORC) geothermal units, where heat from the separated brine vaporizes the working fluid to drive a turbine, as well as N-pentane storage for other industrial plant requirements.
