• Improving the reliability of steam methane reformers
  The reliable and continuous supply of hydrogen to a refinery is of major importance. Dr M. Scholz and M. A. Smith of thyssenkrupp Industrial Solutions discuss how the reliability of the hydrogen manufacturing unit can be improved by equipping it with a PSA bypass, which is triggered in case of a PSA trip. Consequently, the raw hydrogen is recycled to the steam reformer as fuel. In this way the plant is kept in operation while solving the issues that led to the PSA trip and a fast restart of the plant is possible with minimum shut down time.
