Controlling the temperature of a process using a thermal loop is important in many applications. The importance of a power controller is discussed here For any process where temperature needs to be monitored or controlled, a thermal loop is required.…
In some situations, it might be necessary to remove or replace a bolt during operation. This article shows how to determine the proper bolt load to prevent leaks Bolted flange joints (Figure 1) are part of pressure vessel and piping…
Taking a system approach to find the root cause of a problem can be more beneficial than simply replacing a problematic pump. This article explains why We want the best reliability with anything that we work with. In a plant…
Sequencing batch reactors (SBRs) are a variation on the activated sludge process in wastewater treatment. This article provides an overview of SBRs, including their history, current use and future outlook Sequencing batch reactors (SBRs) are a type of wastewater treatment…
This practical guide provides information on proven backwash-tuning techniques that will improve the reliability and robustness of sand filters in water treatment applications Water is a fundamental part of virtually all plants in the chemical process industries (CPI). Examples of…
This overview presents guidance for the safe design of piping systems that are used for the distribution of hydrogen gas Hydrogen gas is a very volatile fluid that has a high propensity to leak. This is a very dangerous and…
Managing the risk from combustible dust explosions involves a number of strategies for preventing explosions, as well as isolating, venting and suppressing explosions if they occur. Complying with applicable NFPA standards is a pathway toward minimizing risk Combustible dust explosions…
The Joukowsky equation is often relied upon to determine the maximum possible fluid pressure inside a pipe, but there are certain scenarios where this equation does not return the expected conservative result for overpressurization We engineers love our formulas. Especially…
Taking a modular approach to capital projects offers a pathway for companies to be proactive, rather than reactive, as they manage project risk in the time of COVID and potential similar disruptions in the future It has been more than…
Developments in laser technology and significantly increased computing power are making process analyzers available for new applications and even for closed-loop control Process analytical technology (PAT) has undergone rapid development in recent years. Further developments in laser technology, the miniaturization…
