Special applications

A special application can be the use of comprerssor not directly for cooling or heating. Instead just gas compression.

Example:

Cern, Schweiz

Plant for cooling the refrigeration shield of the large ATLAS detector at CERN.
Our part is to compress helium from 1 to 18 bar (a), which is then lowered down to 40 K by two expanders.
The 40-degree (Kelvin) gas provides cooling of the shield for the ATLAS detector.

2 pc CHS 1479

Swept volume 2 * 4790 m3/h
Motor power 2 * 880 kW
Cooling capacity at 40 K 2 * 20 kW

Furthermore, after this plant started running, an installation in an existing helium cryo plant of a new high-pressure helium compressor unit , and replacement of a low-pressure compressor unit has been done. And later annother low-pressure compressor.
This system will cool down to 4 degrees Kelvin.

 

 

Swerea MEFOS, Luleå Sweden

Test site at Swerea MEFOS facility in Luleå for the EU-project STEPWISE. It will compress and process blast furnace gas.
The gas comes from the blast furnace at SSAB's plant beside Swerea MEFOS.

Opcon has delivered a gas compressor unit. The unit shall filter, dry and compress approx. 800 Nm3/h blast furnace gas from atmospheric pressure to 25 bar(g)

Compressor: SRM20M
Motor: 351 kW (rated)
