Moving Toward Ultra-Pure Hydrogen

Ivys’ Hydrogen Purification and Generation Solutions efficiently upgrade hydrogen-containing reformate, petrochemical process gas streams and refinery off-gas streams to pure and ultra-pure hydrogen. Ivys provides the most compact, economical and reliable PSA systems available today.

Our hydrogen purification and generation systems have multiple applications for refineries, petrochemical plants, chemical plants or hydrogen producers, such as:

  • Refinery Streams
  • Steam Reformers
  • Ethylene Off-gas
  • Hydrogen Fuel Cells
  • Partial Oxidation/Syngas
  • Coke Oven Gas

Features

Efficient, Reliable, Safe Operation

Ivys’ PSA systems offer unmatched proprietary advantages compared to conventional PSA systems.
These advantages include:

Compact

At least 3-5 times smaller compared to conventional PSA with the same capacity due to reduced PSA vessel size and the use of the rotary valves.

Easy and fast installation

Skid mounted systems with adsorbent preloaded in factory enable “plug-N-play” installation.

Simple control and operation

Only one parameter. The rotary valve speed needs to be controlled during normal operation.

Flexible capacity

Operation capacity can be matched by adjusting rotary valve speed to maximize recovery while meeting product purity requirements.

High recovery

Triple equalization cycle design ensures high product recovery.

Reliable

Availability is typically greater than 99.5 % due to the significantly reduced number of moving parts and long service intervals compared to conventional PSA systems.

Low OPEX

Electrical power is the only utility required for normal operation. Power consumption is typically less than 1 kW.
