Caterpillar has shipped its first order of its Dynamic Gas Blending retrofit kit to a Russian oil and gas company. The gas blending kit adjusts to changes in incoming fuel quality and pressure, allowing engines to run on various fuels without affecting performance.
It allows the option of using dual fuels to meet emission regulations and to lower fuel costs. The kit can maintain diesel performance levels with up to 70% replacement of diesel with gas.
Engines can run on a variety of fuels from associated gas to gasified LNG while maintaining the original engine emissions certifications, with the retrofit kit.
The kit requires no analysis or customer input during operation and no testing is required at rig construction or rig up.
"The fuel savings achieved with this system depend 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.
