Inc. today announced it has shipped the first unit of the Dynamic
Gas Blending retrofit kit to a Russian oil and gas company. The dual
fuel product is now available for order from the Cat dealer network. As
announced previously, the Dynamic Gas Blending kit allows customers to
reduce fuel costs and meet changing emissions regulations by utilizing a
wide range of gaseous fuels in their existing diesel generator sets. The
kit also recently successfully completed an extensive field test for
Encana Oil & Gas (USA) Inc.

The Dynamic Gas Blending kit automatically adjusts to changes in
incoming fuel quality and pressure allowing engines to run on a wide
variety of fuels, from associated gas to vaporized LNG with no loss of
performance integrity. It maintains diesel performance levels with up to
70 percent replacement of diesel with gas, accepts up to 55 percent
inerts. No customer input or gas analysis is needed during operation,
and no recalibration is required when the equipment is moved or the gas
supply changes. No testing is required at rig construction or rig up.
“This is a completely integrated solution that continually adjusts to
varying fuel quality and requires no adjustments or re-testing, allowing
the engine to run at maximum substitution while maintaining a high level
of reliability and durability,” said Sam Ternes, Caterpillar Global
Petroleum engineering specialist.
Designed for compatibility with existing land drilling rig controls and
production multi-generator set control systems, the gas blending kit
provides robust transient response and an integrated gas induction
control which maintains stable generator output. It is easily integrated
with drilling and production generators in the oil and gas industry.
The Dynamic Gas Blending kits include Caterpillar’s newest control
system – EMCP4.4, which easily integrates the engine, generator and the
gas blending system. Features of the EMCP4.4 include:
Plain text display of fault codes
Compatibility with customer inputs through MODBUS protocol and load
Easy-to-view gas system parameters, simple daily walk-around
Engine protection shutdown/startup ability with custom programmable
Compatible with legacy direct rack control systems
“The fuel savings achieved with this system depends on a number of
variables, including the application, the quality of the gas, the
pressure and available volume,” said Russell Goss, Caterpillar Global
Petroleum engineering specialist.
The gas blending kit includes an emergency stop purge cycle, generator
temperature monitoring and air shut-off valves. If fault codes are
detected in the gas system, it will be shut down and the system will
seamlessly revert to full diesel operations. To learn more about the DGB
