$60,000 in savings in just eight months
A 775 MW combined-cycle plant in the northeastern United States was experiencing premature plugging of resin pre-coated, backwashable condensate filter cartridges with resin fines and contaminants. The plant needed an experience team to help them eliminate contamination during start-ups. After careful consideration, Pall was chosen for the project. Pall has an international customer base, and a strong reputation for innovative solutions in the power and utilities industry. After attentively surveying the scene, Pall started to put its plan into action.
Hydro-Guard® CoLD R Series Filter Cartridges
Hydro-Guard CoLD R filter elements are manufactured using the CoLD Melt™ fiber production process. The CoLD Melt process permits the creation of multiple filtration zones within a single filter cartridge. The reverse graded pore density, multi-zone design provides customers with even precoating, efficient backflushing, and long filter life. Many power plants around the world have switched from string wound technology to Hydro-Guard CoLD R products for improved condensate polishing.

Coal Pulverizer
Power generation industry studies have shown that coal pulverizers are an area where improved equipment reliability is badly needed. The Electric Research Institute (EPRI) has determined that 1% of plant availability is lost on average due to pulverizerrelated problems.1 EPRI also identified oil contamination and excessive leakage as two areas where pulverizer drive train failures account for 53% of pulverizer problems.

Hydroelectric Turbines
Hydroelectric turbines comprise approximately 17% of the total number of power generating units in the United States and Canada. According to a North American Electric Reliability Council (NERC) Generating Availability Report, failures of the wicket gate mechanism, turbine governor, generator bearings and lube oil system are among the top 25 causes of forced and scheduled outages and deratings of hydroelectric turbines. This represents a tremendous opportunity to apply state-of-the-art filtration to improve reliability and availability of hydroelectric turbines.

Pall Aria™ Microfiltration system
A major North American utility station deploys conventional lime softening and demineralizers to produce high-quality water for boiler makeup. The utility station is a large coal-fired power plant that operates three coal-fired units. The units are about 600 MW each and were originally designed to handle high sulfur bituminous coal. The conventional system uses coagulant, lime, acid and caustic in large quantities to produce demineralized water. Pall Corporation and plant personnel worked together to develop an integrated membrane-based system to produce high-quality permeate water to maximize ion exchange run times.

Ultipleat High Flow Solution Story
A major Midwestern power plant was experiencing significant losses in power generation capacity. The deposition of copper onto the turbine blades was causing an average loss of 27,000 MWh per year. The copper deposition and imbalance of the turbine blades forced the station to decrease the turbine rotation speed. Near the end of a twelve-month fuel cycle, the station derated by 30 MW, resulting in an average of $30,000 per day of lost generation revenue.

Power Company Improves Gas Turbine Reliability by Removing ‘Varnish’
A power generation company based in Colorado, USA, operating a GE Frame 7A gas turbine on a simple cycle, experienced a steady increase of varnish levels in the lube oil, coating critical system components, identified during routine monitoring of the turbine lubrication system.
The turbine lubrication system of 6,200 litres capacity using ExxonMobil TerresticTM ISO 32 lube oil had been in service for approximately 48,000 hours over a 7 year period, and protected by 5 µm nominally rated return-line filtration of unknown make.

Power Company improves start-up and shut-down procedures by eliminating ‘varnish’ from the control system
A power generation company based in British Colombia, Canada, operating an Alstom GT24B 250MW gas turbine on a combined cycle, experienced stiction of the servo-valves when modulated for various control functions during turbine start-up and shut-down.
