Continuous Catalyst Regeneration

Controlling efficiency in continuous catalyst regeneration maximizes the catalyst lifespan by minimizing thermal damage, and affects the overall quality of the final product.

Continuous catalyst regeneration (CCR) is part of the catalytic reforming process in a refinery where hydrogen and naphtha feed are reacted to create desired end products.

The catalyst used in the reaction is continuously flowing through the reactors and then regenerated. The efficiency of the regeneration process impacts the yield and quality of the end products.

We have decades of experience in process critical measurements for oxygen and moisture.  For oxygen, we developed a dedicated oxygen analyzer in conjunction with the UOP CCR process to achieve the required low-level oxygen measurements during this critical regeneration cycle. For moisture, we provide highly sensitive instruments for this process, with accurate, reliable results that are unaffected by reformer contaminants such as compressor oils and high boiling point hydrocarbons.

    Oxygen monitoring

    During the regeneration cycle, coke deposits are removed from the catalyst by oxidation. Measuring the oxygen content at this stage is critical to minimize thermal damage, maximize the catalyst lifespan and optimize process efficiency.

    Hydrogen recycle gas

    Proper moisture balance in feedstocks and hydrogen recycle streams must be maintained to optimize product yield and catalyst life. Accurate and rapid results are required despite wide variations in moisture content.
