Propionic Acid Production from Propionaldehyde

This column is based on “Propionic Acid Production from Propionaldehyde – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/propionic-acid-production-cost. Propionic acid (also known as propanoic acid) is a carboxylic acid commonly found in nature, mainly…

Facts At Your Fingertips: Hopper Outlet Geometry and Arching

When transferring stored bulk-solids materials from hoppers, bins and silos, flow stoppage can occur because of bridging or arching at the vessel outlet. Hopper outlets must be large enough to prevent cohesive arches or stable ratholes from developing. Determining the…

Evaporators: Energy Conservation Strategies and Process Control

Several strategies for improving energy consumption and process control in evaporation processes are presented here In industrial evaporation, a heat source (usually condensed steam) is used to concentrate a material through the removal of a liquid solvent. There are several…

Rapid Maintenance Response: When Plants Can’t Wait

Even with advanced predictive technologies, unplanned equipment failures can still occur. In these instances, as shown in this boiler example, rapid maintenance action is crucial to minimize downtime Maintenance activities generally fall into two categories — reactive and preventative. The…

Methods For Testing Steam-Trap Stations

Testing steam-trap stations can be very easy if the plant provides the correct equipment, training and commitment to the steam-system management program When it comes to testing steam traps, a frequently asked question is, “what is the best method?” The…

Technology Profile: Sodium Chlorate Production

This column is based on “Sodium Chlorate Production – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/sodium-chlorate-production-cost. Sodium chlorate (NaClO3; also known as chlorate of soda) is an odorless inorganic salt with colorless crystals and…

Facts At Your Fingertips: Cost Estimation and Risk

Understanding project risks is critical to arriving at useful cost estimates. Since each capital project in the chemical process industries (CPI) is somewhat unique, it can be difficult for engineers and project leaders to price risks in their estimates and…

Process Changes: Understanding and Mitigating Fire-and Life-Safety Risk Factors

When making a change in your process, do not overlook new potential hazards that may arise, as discussed here Large-scale chemical processing can be inherently risky. This is especially important to keep in mind when making changes to a process.…
