Dresser-Rand has decades of experience revamping,
rerating and modernizing reciprocating compressors and gas engines. This includes:
Meeting Modified or Completely New Service Conditions
Dresser-Rand’s industry experience, expert machinery and
application knowledge, and state-of-the-art product and service offerings enable us to
fully evaluate and implement the necessary equipment changes to reliably and safely
produce:
- Changes in performance conditions (pressures, flows, gas
constituents, etc.)
- Changes in capacity through modifications of cylinders and associated
gas piping
- Gas compatibility via changes in exposed component metallurgy
- Enhancements to or addition of auxiliary support systems (e.g.,
cylinder cooling, frame and cylinder lubrication, capacity control, etc.)
- Equipment optimization Uprating Power to Modern Design Levels
(Engines)
Uprating Power to Modern Design Levels (Engines)
 Dresser-Rand (Clark) 5,000 horsepower TCVD-10 engine on
natural gas transmission service
New engine design improvements can be incorporated into many
existing engines to uprate them to modern horsepower and speed levels.
Typical examples of gas engine uprate conversions are listed below:

Some turbocharged engines can also be
converted to take advantage of ambient rating. This allows engines to produce 24 percent
more power at a 40 ° F versus a 100 ° F ambient temperature.
Converting to Motor Drive (Engines)
Legislative controls on gas engine exhaust
emissions are threatening the continued service of some integral gas engines.
An option available to engine owners is a motor drive conversion
consisting of the following:
- Removal of engine power cylinders
- Removal of air, fuel and exhaust systems and associated accessories
- Installation of an electric drive motor
Note: Availability of electric power and space
constraints must be considered for all motor conversions
Benefits of an electric drive conversion will/can include:
- Zero exhaust emissions
- Improved reliability
- Renewed unit with reduced cost of ownership
- Option to uprate and/or revamp for increased capacity
- Implementation of compressor upgrades to reduce cylinder fugitive
emissions and improve reliability
