PSB Industries

PSB Industries Inc., General Air Division, specializes in the Design and Fabrication of compressed air, gas, and liquid dehydration and purification systems. Our standard and custom packaged systems remove moisture and contaminants from process streams. Adsorption technologies utilizing activated alumina, molecular sieve, activated carbon, and other selective adsorbents are employed to dehydrate, treat, and purify the fluid stream to the required exit specification. Catalyst systems are also designed and often incorporated within adsorption packages for purification. PSB units are installed worldwide and currently serve the Air Separation, Chemical, Petrochemical, Refining, Fuel Gas, and Electronics markets. PSB fabrication capabilities and quality of packaged systems are unmatched. Vessels, piping, structural, control panels, sandblasting, painting, instrumentation, insulation, testing, etc are completed under “one roof” to closely monitor and quickly react to scope changes. PSB “NG” series dryers are specifically designed for natural gas fueling stations and are available in wide range of single vessel or dual vessel sizes and configurations to suit each application. As gas supply pressure varies, PSB’s typical dryer pressure options range from 200 to 1525 psig maximum working pressures. The dryers are designed and manufactured in Erie, Pennsylvania, USA with certified quality system meeting ISO 9001:2008

NG-SV Single Vessel Natural Gas Dryer PSB type NG-SV is an ideal system for drying small volumes of natural gas for stations with intermittent use. Each unit is conservatively sized to remove moisture from gas upstream of the natural gas compressor. When the initial charge of desiccant has reached maximum drying capacity, it can either be replaced or regenerated with an external regeneration package, consult PSB for more information. An optional “DDP” Digital Dew Point meter will provide indication of effluent dew point confirming performance or need for desiccant replacement/regeneration.

Dryer Design Features:

PSB’s standard package includes factory fit pre-filter and particulate after-filter.

• Adsorber vessel designed, manufactured, and per ASME code Section VIII. *Alternatives available • Stainless steel desiccant screens
