Fuel Gas

Fuel Gas Streams are frequently contaminated with liquid aerosols. The liquid exists as a stable and persistent “smoke” in the gas stream. The liquid contaminant can enter the gas stream through any one of a variety of events including – phase separation and condensation, compressor lube-oils from compression, chemical addition to pipelines (including corrosion inhibitors), and entrainment from overheads of contact towers.

Conventional Approaches to separating the liquid contamination have utilized either demister pads, or horizontal filter-separators. These devices have been approximately 20 – 40% effective at removing the liquid aerosols from the gas streams. The reason for this inefficiency is directly related to:

• Aerosol droplet size distribution
• Flow configuration in the separator

Conventional devices are ineffective because they are not able to capture the most penetrating aerosols, and are unable to effectively remove even those aerosols that they capture.

Pentair's technologies have been developed to address the inherent deficiencies of the conventional gas-liquid separators, making it possible, for the first time, to effectively remove liquid aerosols from gas streams. This presents the capability of providing effective separation from nano-levels to that approximating a demister pad.
