• Next generation exhaust gas aftertreatment for flexible power generation and quick starts

• Emission control systems for power plant supporting the use of renewable energy

• Combikat exhaust gas purification for natural gas medium speed engines

Hug Engineering is to supply the emission control for a medium speed gas engine power plant located in Arizona, U.S. The order booked in December 2017 covers 10 emission control system for gas engines to be delivered in the second and third quarter of 2018. The first part of the plant will be operational in mid-2019.

The new plant offers flexible power production and supports the increased volume of renewable energy for the region. The target for the utility company is to be able to extend the share of renewables to 30% of their total portfolio by the end of next decade. As a result of the company’s new energy mix, with renewables and gas engines coming online, not only the carbon dioxide emissions, but also the nitrogen oxide emissions will be reduced. The new engines, that are equipped with ultra-low NOx emission control systems from Hug, will replace two existing generating units and increase the plant's efficiency. This also leads to a reduction of NOx emissions by more than 50% as compared to the cur-rent power production situation.

The new Hug Engineering emission control system offers faster starts and allows the power plant to reach its emission targets in a shorter time.

As more solar and wind power is added to the grid, our customers will need to balance the electrical energy demand by providing generation capacity that efficiently can handle quick and variable changes in the power need. Besides quick starts, it is important that the next generation of emission control systems will allow the power plant to operate on low loads and to ramp up and down quickly.
