Graver in Natural Gas Combined Cycle Plants

Graver Water is a key supplier of water and waste water treatment solutions to the natural gas combined cycle power generation market. Currently, over 30% of the electricity generated in the United States comes from natural gas fired power plants. Of that number, more than 80% of those power producing plants are natural gas combined cycle (NGCC) type power generating facilities. The U.S. Energy Information Administration estimates that NGCC plants will overtake coal as the leading fuel for power generation by 2035 and that combined cycle power generation will continue to grow.

Combined cycle natural gas fired steam turbines, sometimes called combined cycle gas turbines (CCGT), require significantly less cooling water than traditional steam turbines that use coal or nuclear fission as their source of heat. This reduces, but does not eliminate the need for make-up water and waste water treatment needs.

Graver’s water treatment solutions support the growing need for zero liquid discharge (ZLD) facilities as well as the recycling of water in these facilities. With proper planning and engineering, Graver’s equipment can support today’s environmental needs for ZLD power plants.

Critical Application – Condensate Polishing

Condensate Polishing Powers Combined Cycle Operations Including NGCCs Condensate polishing (CP) is an essential component of combined cycle plant design and operation because high purity condensate maximizes uptime. CP safeguards high-value plant assets by reducing startup/downtime, stabilizing cycle chemistry, minimizing corrosion transport and optimizing operations. CP is particularly important for air-cooled condenser (ACC) systems, oncethrough steam generators and plants with frequent startups. Utilities can’t afford to ignore this vital and economical system that consumes a tiny portion – typically 1% – of plant construction budgets. Graver Technologies and Graver Water Systems (Graver) provide the world’s best CP for combined cycle operations of all sizes, footprints, locations, equipment types, flow rates, chemistry profiles and condensers. Nobody else in the world treats water as well as we do.

Key Product

The Powdex® precoat filter demineralizer system removes both suspended solids and ionic contaminants in a single compact unit. These proven high performance systems are customized to any power plant design and quickly achieve target chemistry for fast online operation. Powdex systems are particularly suited for ACC facilities’ higher condensate temperatures and corrosion product transport levels. Powdex stands alone as the most economical and effective CP choice for all types of combined cycle plant operations.

What Makes Powdex® the PREFERRED CONDENSATE POLISHER?

Fit any footprint: New and retrofit Powdex® systems fit vessels, precoat septa, piping, state-of-the-art process controls and ion exchange resins into very compact spaces.

Install quickly: Off-site construction and skid-mounting mean quick installation and rapid start-up.

Remove soluble and suspended contaminants: Systems capture suspended particles, iron, copper silica, activated corrosion products and salts, and more.

Meet tough challenges: Systems address flow rates, particulate types and chemistries including unusual heavy metals.

Operate at higher temperatures: Powdex® anion is not subject to the same 60°C temperature limit as bead anion exchange resin to avoid degradation. New Powdex® resin is applied with every precoat.
