> <<Temperature control is important for separation and reaction
> processes, and temperature must be maintained within limits to ensure
> safe and reliable operation of process equipment. Temperature can be
> measured by many methods; several of the more common are described in
> this subsection. You should understand the strengths and limitations of
> each sensor, so that you can select the best sensor for each
> application. In nearly all cases, the temperature sensor is protected
> from the process materials to prevent interference with proper sensing
> and to eliminate damage to the sensor. Thus, some physically strong,
> chemically resistant barrier exists between the process and sensor;
> often, this barrier is termed a sheath or thermowell, especially for
> thermocouple sensors. An additional advantage of such a barrier is the
> ability to remove, replace, and calibrate the sensor without disrupting
> the process operation.>>

> Flow Control With Ball Valves
> <a href="http://www.pipingdesign.com/controlvalves.html">http://www.pipingdesign.com/controlvalves.html</a>
>
> <<When a globe valve starts to open, it will always jump open rather
> than move smoothly. In order to overcome linkage and internal
> resistance, more movement is needed by the actuator than low flow
> requires. Globe valves are installed with flow tending to push open the
> seat. As soon as flow is established, the pressure pushes on the seat,
> the stem rises, and more flow than needed occurs. There is a travel zone
> where about 10% of CV rating occurs on opening. Ball valves do not have
> this jump effect. Rotation is slow, rack and pinion linkage is used, the
> tendency of flow is to close a ball, and a high seal resistance, all
> contribute to smooth rotation without jumps, resulting in turndown
> ratios from 160:1 to 400:1, depending on quality of actuators, valves,
> and signal. Minimum flow is fully controllable under part load
> conditions. Ball valves with Belimo actuators are exceptionally good at
> control, and fully utilize the control signal.>>

> Piping System Corrosion Control
> <a href="http://www.pipingdesign.com/materials.html">http://www.pipingdesign.com/materials.html</a>
>
> <<Among other factors, the integrity and life of a piping system is
> dependent upon corrosion control. As discussed in previous chapters of
> this manual, internal corrosion of piping systems is controlled by the
> selection of appropriate materials of construction, wall thickness,
> linings and by the addition of treatment chemicals. External corrosion
> can also be addressed through materials of construction. However, other
> methods may be required when metallic piping systems are applied.>>
