POWER CASE HISTORY - ONGUARD 2-PLUS OPTIMIZES PROGRA M PERFORMANCE AND INCREASES POWER PRODUCTION $300K/YR
Background
CustomerNeeds
� New England 19 MW zero liquid discharge power plant with 5 ppm iron in well water
� Excessive condenser and tower fill fouling
� Reduce frequency of shutdowns for condenser cleanings� Maintain peak power generation efficiency� Clean-up tower fill
8 Confidential and proprietary.
Ashland Solution
Benefits
� OnGuard™ 2-plus proved fouling and ORP correlation� Relocated chlorination feed to oxidize iron. Prevented
reaction with silica.� Established ORP target for halogen control, removing slime
� Improved power generation 5%; revenue increased over $300,000 per year
� Reduced outages and maintenance costs� Increased side-stream silica removal from 10%-90% via
coagulant optimization reducing fouling tendency
POWER CASE HISTORY - COOLING WATER TECHNOLOGY INCREASES REVENUE $1.6 MILLION, CHEMICAL SPEND CUT 20%
Background
CustomerNeeds
� US independent power producer faced changing environmental discharge restrictions, which limited cooling tower water chemistry control
� Improve fouling and corrosion control� Meet environmental discharge limits
9 Confidential and proprietary.
Ashland Solution
Benefits
� Treatment program including OnGuard™ 2-plus analyzer performance-based monitoring and control equipment and augmentation with Drewsperse 7130 dispersant to eliminate organic fouling
� Increased power generation 6.7 MW; revenue increased over $1.6 million
� Reduced chemical spend 20%� Exceeded corrosion and fouling control targets � Improved condenser cleanliness by 15%
