An inaccurately sized or improperly specified filter can undermine an entire high-performance liquid filtration system. There are a dozen key parameters to assess to determine the proper specification.
In Part 5 of this series on distillation control and optimization, we find that adding a side-stream component to your process gives an additional degree of freedom, but makes it even more essential to not mismatch the variables.
Automating procedures within control systems can serve to make your operators more effective and more consistent. With studies showing more than 40% of all plant incidents stemming from some form of human error, it makes sense to give automation a larger role in day-to-day operations.

Users seeking appropriate process safety systems arent getting enough help from unspecific standards and ideal-world certifications. Heres how to gain useful safety capabilities in a buyer-beware world.
Many companies decide not to build up certain capabilities in-house mainly because they dont have sufficient regular demand for them. Gamma scanning of distillation columns is a case in point, but on-site scanning specialists may be the wave of the future.
From large petrochemical units to tiny pharmaceutical pilot plants, day-to-day operations depend upon providing compressed gases in a controlled, safe and environmentally conscious manner. Correct gas handling also can improve process efficiency.
With increasing energy prices and public sensitivity to energy consumption, many plants are paying more attention to optimizing distillation. Simple and low-risk operational changes often can provide substantial savings.
Understanding the purpose of control and safety systems helps users ensure each is appropriately optimized. The duties of the SIS are to protect the people, environment and assets against unsafe conditions.

More and more companies are placing greater emphasis on maintenance and seeking help from vendors to boost the effectiveness of their efforts, as some recent major investment decisions demonstrate. Many automation companies now are benefiting by building up asset management services alongside process control capabilities.
Your current control system can probably do more than you think. Everybody can agree that diagnostics are a good thing they can identify problems early, and keep the plant running at peak performance. Learn how your existing control systems and analog instruments can deliver diagnostic capabilities, at a fraction of the cost of system or instrument replacements.
Control's Béla Lipták continues his series on control of distillation processes, this time focusing on managing reboiler flow, temperature, feed rate, loading and reflux for economy, stability and safety.
