The product technology arm of oil giant ExxonMobil has launched a new gas turbine oil said to increase the productivity and efficiency of turbines in gas plants.

ExxonMobil Lubricants & Specialties has unveiled Mobil DTE 932 GT, a gas turbine oil designed to enhance the performance and reduce the downtime of combustion gas turbines with a common hydraulic and bearing oil reservoir, the firm said in a press release. According to ExxonMobil, Mobil DTE 932 GT meets the standards for General Electric frame 3, 5, 6, 7 and 9 turbines.

Gas turbine engines are made up of a compressor, a combustion area and a turbine. The compressor compresses incoming air to high pressure. The combustion area burns fuel and produces high-pressure, high-velocity gas, and the turbine extracts the energy from that gas.

One of the by-products which stem from the use of gas turbine oil is varnish, a sticky deposit which can adhere to the metal surfaces of the equipment, such as piping, valves and heat exchangers. According to ExxonMobil, their new gas turbine oil addresses this issue.

“Varnish can have a significant detrimental impact on gas turbine operation, but Mobil DTE 932 GT offers the potential for greatly reduced varnish formation,” said Yan Côté, global business development advisor, ExxonMobil  Lubricants & Specialties.   “Other performance benefits of Mobil DTE 932 GT include exceptional high temperature performance, outstanding deposit control, excellent foam control and air release.”

Gas turbines are used in a variety of applications, namely in liquefied natural gas (LNG) production, as LNG plants rely on this equipment to drive compressors which cool and liquefy the gas for transportation.
