Is the performance of catalysts in your plant declining with age? Is it time to replace them? Take this webinar for help in deciding.

In 60 minutes, you’ll consider how catalyst performance declines with age and how its replacement becomes an economic necessity. Using the tools and rules of thumb provided, you’ll be equipped to evaluate replacement timing while considering the time value of money involved in the catalyst life cycle. You’ll see these tools illustrated through hypothetical examples from the ethylene oxide production process. And, you’ll gain principles that you can apply to any heterogeneous or homogenous catalyst system with significant costs and decaying performance.

Take a look at your agenda:

  • How to characterize catalyst performance in economic terms using plant data
  • How to compare the short-term decision to continue with aged catalysts versus replacing with new
  • Developing a strategic plan for optimizing catalyst life cycle
