Gas engines as compressor drivers

Moss Bluff, Houston, USAExtension of underground gas

storage facility- 100 000 Nm3/h; 34 -> 138 bar - 1 x 18V34SG + reciprocating

compressor- in operation since 2000

Bucholz, GermanyGas storage in aquifier

- 60 000 Nm3/h; 60 -> 140 bar - 1 x 12V25SG + reciprocating

compressor-in operation since about 2000


Oil fields / Associated Gases

• Dygoil, Equador• 2 x Wärtsilä® 16V32GD• 11MWe• The power plant started up in

March 2004, and it operates with oil field associated gas as the main fuel, and Crude oil as supplementary fuel.

• The plant is designed to utilise the associated gas and to minimise the need for flaring, and unnecessary CO2 emissions are avoided


Bio-Oil

Pentesilea

Monopoli, Italy

3 x Wärtsilä® 18V32

24 MW running on liquid biofuel

The power plant, which started up in August 2004 operates with vegetable oil as fuel. Since thefuel is renewable, theCO2 added to the atmosphere is negligible.

SCR for NOx abatement is installed.
