★Performance Case Ⅱ: A Hydrogen Supply Unit for a Large Polyethylene Project in the Baltic Region

The PSA hydrogen separation and purification unit designed, manufactured by Keterise utilizes the company's newly developed adsorbent materials and optimized process parameters. By increasing the operating system pressure, it ensures high recovery rates while reducing energy consumption by more than 20%.

★Performance CaseⅠ: Hydrogen Recovery from Refinery Off-Gas, Kazakhstan

Customer Challenge: The customer aims to recover hydrogen from the tail gas of a catalytic cracking unit. However, the complex composition of the gas stream and significant pressure fluctuations pose challenges to the recovery rate and stability of traditional PSA technology.

Keterise Solution: An integrated membrane separation + pressure swing adsorption (PSA) unit, where the former achieves preliminary separation and pressure boosting, and the latter provides fine purification, effectively enhancing the recovery rate and operational stability.

Customer Feedback：The Keterise solution exceeded our expectations
