Capstone announces new severe environment air filtration system

Published on: 

Capstone Turbine Corporation has launched a new cleanable severe environment air filtration system for its line of microturbine products. It recently received an order for three C65 microturbines utilizing this new filtration system for a flare gas reduction project in Oman.

During sand and dust storms common to most hot arid desert areas, particulate concentrations close to the ground can reach levels 20,000 times those in typical U.S. cities. Even at an elevation of above grade, particulate concentrations about 1,000 times U.S. urban averages are frequently observed during sandstorms and dust storms. Such dust and dirt loads can cripple conventional air filtration systems, cause massive maintenance expenditures and allow excessive dust concentrations to be ingested by the turbine.

The filters are a scaled down version of the filters used in much larger industrial and aero-derivative gas turbines and allow operation for prolonged time periods in desert environments like the Middle East.

Pipeline Supply Company, Capstone’s distributor for Oman and Qatar, secured the order for multiple C65 cleanable severe environment units. The microturbines will be fueled by the associated gas that is a natural byproduct of the oil extraction process. This gas, which can be of poor quality, is normally vented or flared into the atmosphere because it is not of the quality to be put into natural gas pipelines. Additionally, oil and gas operations are typically in remote areas, which means there is no infrastructure available to clean and capture the gas and bring it to market.


Capstone’s microturbines help alleviate both problems. First, they are able to run on associated gas with very little pre-treatment and convert it into electricity to be used onsite. Secondly, they are able to operate in remote and harsh environments, like the desert, with very little maintenance while simultaneously having a positive impact on the environment.

According to the EIA (Energy Information Administration), Oman ranks as the 7th largest proved oil reserve holder in the Middle East and 22nd largest in the world at an average of 1 million barrels a day of production in 2016.

“Oil prices posted their strongest opening to a year since 2014 on Tuesday, with crude rising to mid-2015 highs amid large anti-government rallies in Iran and ongoing supply cuts led by OPEC and Russia,” said Darren Jamison, President and Chief Executive Officer of Capstone. “With increasing crude oil prices and a growing interest in utilizing associated gas to create onsite energy we are developing a new line of cleanable severe environment air filter systems to improve the overall turbine performance in the growing Middle Eastern markets,” added Mr. Jamison.
