Wartsila 20V 34SG Natural Gas Engines - Midwest

The Challenge

A power plant in the Midwestern United Sates had an
install base of 9 Wartsila 20V 34SG natural gas engines.
Their previous crankcase filters were static and simply
acted as a rough baffle for the oily vented crankcase
emissions. The result was visible emissions into the
atmosphere and condensing oil on the side of their
building and on the ground. These engines ideally operate
under slight positive pressure, and the operator
asked Solberg to maintain this natural pressure while
eliminating the visible emissions. Solberg was given
this opportunity as a referral from a successful install
on the same engine make and model.

The Solution

A trained Solberg representative visited the site and
evaluated the current set up. Solberg presented the
same recirculation unit thatsuccessfully eliminated
the visible oil mist at a similar install. The Solberg
unit included a recircula tion piping configuration to
continuously maintain the natural crankcase pressure
while capturing the oily emissions. This type of system
is self‐balancing, does not add any additional pressure
or vacuum, and does not require any adjustments. An
additional 3 engines were later installed and supplied
with Solberg Crankcase Ventilation Systems.
