Canned motor pump for LCO2 Loading and Unloading Stations
CO2 capture plays a crucial role in various industrial processes. For efficient storage and reuse of captured CO2 , purification and liquefaction processes are advantageous. As a result, the CO2 – referred to as LCO2 – is available as a cooled liquid and stored in tanks for transportation. Using loading and unloading stations, the LCO2 is transferred from the tank into transport systems such as trucks, railcars, or ships and taken to its next destination.
Your benefits
- Compliance: Manufacturer’s declaration according to EC 1935/2004 available for purified CO2
- Materials: Extensive pump portfolio in steel and stainless steel
- Efficiency: Lowest life cycle costs due to minimal maintenance requirements
Application areas
- Loading stations
- Unloading stations
Loading Station for Purified LCO2 in Methane Production
Requirements
In this application, the goal was to safely, efficiently, and autonomously transfer food grade LCO2 from a storage tank to trucks. The filling process needed to be carried out as fast as technically feasible. To ensure a smooth and autonomous long term operation without leakage and with extended maintenance intervals, canned motor pumps were selected. HERMETIC developed a special pump design specifically for food grade LCO2, including a manufacturer’s declaration according to EC 1935/2004, ensuring safe and clean handling. This enables the transferred LCO2 to be reused in the food industry or pharmaceutical applications.
| Delivery rate: | 40 m3/h |
| Pumping head: | 38 m |
| Operating temperature: | –27 °C |
| Refrigerant: | CO2 / LCO2 |
| System type: | Loading station |
The pump used
The special design incorporates dedicated food grade materials. For this reason, the pump is built in stainless steel, including special bearings and seals. To ensure the highest quality, all LCO2 wetted parts come with material certificates according to EN 10204 3.1.
For fast truck unloading, a CNF 50 200 with a CKPx 12.0 motor was selected. This is a single stage canned motor pump, designed for PN25 pressure rating.
This pump series is particularly suitable for high flow rates and medium discharge heads.
The customer was especially convinced by the pump‘s long maintenance free operating life.
Medium / refrigerant
Purified, liquefied CO2 can be reused in the food industry or pharma sector, contributing significantly to reducing the CO2 footprint.
CO2 is increasingly used as a refrigerant as well. Common applications include supermarket refrigeration and industrial cooling systems. It can be used in different system designs:
- Subcritical in cascade systems
- Transcritical in all CO2 systems
- As a secondary refrigerant
CO2 offers major advantages such as excellent heat transfer coefficients, very low viscosity, and high environmental compatibility.
