LNG Filling Station Ennshafen

The Donaustrasse site in Ennshafen was chosen by RAG for its first LNG filling station due to its ideal location in Upper Austria.

Transport companies that use LNG will be able to refuel vehicles with the fuel of the future without having to make major diversions.

Ennshafen is not only Austria’s newest public port, but also its most modern. The port and neighbouring business parks in Upper Austria and Lower Austria form the largest contiguous industrial zone in the Upper Danube region, with an area of over 350 hectares. As a result of extensive investment in infrastructure and state-of-the-art technology, the port has become a logistics hub for three different modes of transportation, and an important business location for the Enns-Perg-Amstetten area, providing employment for more than 2,000 people.

Directions

In the heart of Europe

Western and Eastern Europe are linked by the Rhine-Main-Danube Canal, and Northern and Southern Europe by one of the continent’s most important rail routes. Ennshafen port is situated at the intersection of these transportation axes.

It’s all about the location

Ennshafen port has access to the three most important transportation modes – rail, road and water. Its ideal location on Europe’s main traffic axes opens up direct transportation routes and facilitates implementation of
multi-modal logistics solutions.

– Link to the A1 Westautobahn motorway via the B1 Enns-Asten bypass

– Direct link to the major urban centre of Steyr via B309A

– Goods station and connecting line to Austria’s Western Railway

– Access to the Rhine-Main-Danube Canal

   

Functional diagram


01 | LNG storage tank

The LNG storage tank is a horizontal, cylindrical, doublewalled container, which is vacuum-insulated using perlite. The inner container is made from stainless steel, and the outer container from carbon steel.

02 | Vaporisers (pressure build-up and saturation vaporisers)
Pipes with star-shaped aluminium fins are attached along either side of the container, to act as vaporisers. These provide pressure build-up when the storage tank is filled and saturation when LNG is withdrawn via the dispenser.

03 | LNG pump
The built-in immersion pump is permanently submerged in the LNG.

04 | Air compressor (piping)
The air compressor and drier are built in to an ISO standard frame with the required process valves and piped connections.

05 | Nitrogen tank (LIN)
When necessary, liquid nitrogen is used to cool stored LNG; it is stored in a separate tank.

06 | Dispensing pump (dispenser)
LNG is withdrawn via the dispensing pump. Withdrawal volume is measured using an integrated mass flow meter.

07 | Customer-activated terminal
The customer-activated terminal opens the dispenser, allowing truck drivers to refuel using a special card.

08 | Electrical container
Electrical switchgear and the control system are built into a separate container.
