Capacitance Manometers for Use in Lyophilization Processes Lyophilization, also known as cryodesiccation, or more commonly “freeze-drying” is a dehydration process typically used to preserve a perishable material or make the material more convenient for transport. The freeze-drying process works by exposing a material that has been frozen to a vacuum environment. This lowers the vapor …

Determining Safety Integrity Levels for your Process Application Safety Instrumented Systems (SIS) are installed in Process Plants to mitigate process hazards by taking the process to a “safe state” when predetermined set points have been exceeded or when safe operating conditions have been transgressed. The SIS is one Protection Layer in a multi-layered safety approach since …

Three Element Drum Control How can steam drum level be controlled to maximize both stability and responsiveness? The best method is to feed forward (FF) the steam flow to the level PID loop and cascade the output of that loop to the setpoint of a boiler feedwater (BFW) flow loop. This arrangement is called “Three Element …
