Power+Energy – Fueling the Hydrogen Economy

Hydrogen Separators

[custom_frame_right]Hydrogen Separators for Fuel Cells[/custom_frame_right]Power+Energy Hydrogen Separators produce ultra-high purity hydrogen from hydrogen rich gas streams for Fuel Cells.  Each H2 separator may be custom designed to match the specific conditions of the customer’s application.  Power+Energy manufactures H2 separators ranging in hydrogen output from 0.5 slpm, capable of feeding a 50W fuel cell, up to 1,200 slpm, capable of feeding a 120kW fuel cell.
Our Separator technology is often used to extract the hydrogen from reformate streams generated by steam or auto-thermal reformers.  In other cases P+E Separators extract H2 from a process by-product stream, from bio-gas (digesters, etc.) or from closed-circuit H2 recirculation systems.[custom_button text=”H2 Separator Brochure” title=”Hydrogen Separators” url=”http://powerandenergy.com/pdfs/hydrogen-separators.pdf” size=”medium” bg_color=”#FF5C00″ text_color=”#FFFFFF” align=”right” target=”_blank”]

 

Design and Operation

Power+Energy Hydrogen Separators use Micro-Channel Palladium Alloy Membranes to extract hydrogen from the feed stream. For mixed gas streams containing sulfur compounds, a sulfur-tolerant palladium alloy is used.  In some applications, customers use a sweep gas, either nitrogen or steam, to boost the hydrogen recovery of the H2 separator.

[custom_frame_right]separator-anatomy[/custom_frame_right] Basic Terms:

  • Reformate: Outlet gas mixture from Fuel Reformer
  • Raffinate: Waste gas stream out from separator
  • Permeate: Ultra-pure hydrogen stream from the separator

Operating Parameters:

  • Maximum reformate inlet pressure = 300 psig
  • Operating temp range = 300-500°C, recommended temperature = 400°C
  • Maximum pressure differential = 180 psi (reformate press. – permeate press.)
  • Maximum reverse pressure differential = 10 psi (permeate press. – reformate press.)
  • Membranes should not be exposed to H2 when below 300 °C to avoid embrittlement.
  • It is recommended that a backpressure regulator is installed in the raffinate line.
  • Preheat membranes with steam, hot air or hot inert gas prior to flow of H2 or reformate.
  • Purge membranes with steam or inert gas prior to allowing membranes to cool below 300°C.
  • It is recommended to monitor the raffinate outlet gas temperature in order to ensure that the membrane temperature remains above 300 C while h2 containing gases are flowing through the separator.
