ANDRITZ Orders Hydrators for Flue Gas Desulphurisation System at OG&E´s Sooner Power Plant

In 2014, Oklahoma Gas & Electric Corp. (OG&E) began implementing a $1.1 billion capital improvements plan to meet EPA clean air mandates at some of its power plants.

As a result, two Circulating Dry Scrubbers for air pollution control will be added to the coal-fired units at OG&E's Sooner Power Plant located near Red Rock, Oklahoma. The lime hydrating units for the ANDRITZ scrubbers will be supplied by Gebr. Pfeiffer (USA) as part of an Air Quality Control System (AQCS) for Sooner Power Plant Units 1 and 2.

The order for four Gebr Pfeiffer Lime Hydrator Systems was placed through ANDRITZ Inc. of Columbia, Maryland, ANDRITZ supplies scrubbers and other air quality control technology for the power generation and heavy industrial markets.

The Gebr. Pfeiffer scope will include: 4 KLV 02/630-4.0 hydrators, weigh feeders, bag filters for dedusting the hydrator's exhaust vapors, erection start-up services, training services.

The KLV 02/630-4.0 hydrators allow for 'dry injection' - the process of adding water to pebble lime in order to produce a dry, volume-stable lime hydrate.

Delivery of the lime hydrator systems (two for each unit) at the OG&E Sooner Plant is scheduled in July 2016 for Unit 1 and December 2016 for Unit 2. OG&E has to comply with the EPA federal regulations by January 2019.
