Diesel Substitution of 66% for Most of the Load Range

Caterpillar 3512B generator sets with Cat Dynamic Gas Blending allowing the engines to run on a mix of natural gas and diesel have achieved diesel substitution rates of 66% for the majority of the load range for a gas supplier in the Tarim Oilfield in China, “a significant accomplishment in the region,” Cat said this month.

Caterpillar 3512B engines with DGB – dynamic gas blending, allowing them to run in large part on natural gas – are on the job in China.

Caterpillar dealer China Engineers Limited led Caterpillar efforts on the sale, commissioning and continued product support, the manufacturer reports.

‘Same Transient Load Response’

“For the customer, the primary benefit of the DGB solution was the substitution rate achieved during a comprehensive testing time, delivering unmatched performance in the region,” Caterpillar oil and gas Asia Pacific product support manager Hon Meng Lim said in a release.

“The generator sets delivered the same transient load response operating in dual fuel mode as they did in diesel mode without any unexpected shut-downs or load-sharing issues,” he said.

CNG, LNG or Field Gas

Operators can run the DGB equipment with confidence on compressed natural gas, liquefied natural gas, “and a wide range of field gas,” Caterpillar says. “The system automatically adjusts to changes in gas quality without the need to perform any recalibration or adjustments to the system during or between jobs.”

Cat notes that its DGB kit for land drilling and production includes an EMCP 4.4 panel as standard equipment. In addition to handling such routine generator functions as paralleling and load sharing, the EMCP 4.4 can automatically start and stop generators based on overall rig power demand. The kit is backed by a full factory warranty and designed to be easily ordered through the Cat dealer network.

‘Single-Source Supplier’

“For our customers, it is convenient for us to service as a single-source supplier with flexible, fully-supported power solutions for their operations,” Lim said. “The importance of a factory-issued warranty has undoubtedly contributed to the DGB kits popularity in China.”

The Tarim Basin is in the Xinjiang region of northwest China.
