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.
Faster. Smaller. Smarter. Modular. All express the future of process analytics. And un-stoppable describes the ongoing migration of process analytical instruments to continuous, online, field-mounted use at chemical plants.
Residue curve mapping is a powerful tool to better understand the design and operation of distillation columns. This article describes how to use residue curve maps to check the feasibility of separation of homogeneous mixtures and for developing the conceptual design of towers.
