Understanding the Piping & Instrumentation Diagram in Process Control

piping & instrumentation diagram
Piping & instrumentation diagram
P&ID's (piping & instrumentation diagrams), or Process and Control Flow Diagrams, are schematic representations of a process control system and used to illustrate the piping system, process flow, installed equipment, and process instrumentation and functional relationships therein.

Intended to provide a “picture” of all of piping including the physical branches, valves, equipment, instrumentation and interlocks. The P&ID uses a set of standard symbols representing each component of the system such as instruments, piping, motors, pumps, etc.

P&ID’s can be very detailed and are generally the primary source from where instrument and equipment lists are generated and are very handy reference for maintenance and upgrades. P&ID’s also play an important early role in safety planning through a better understanding of the operability and relationships of all components in the system.

Optimizing the Steam Generation Cycle and Condensate Recovery Process for Profit

Steam generation and condensate recovery
Boiler for steam production.
Steam generation and condensate recovery systems can vary in complexity depending on the steam end usage and process requirements, e.g., steam for electricity generation or to support a paper mill operation versus that for a small to mid-size specialty chemical process operation.

At the heart of the system is the boiler/steam drum. Regardless of size, its primary functions are as follows: to provide ample surface area (based on steam needs) for the efficient separation of water and steam; provide storage capacity to meet immediate boiler feed water requirements or minimize the effects of the introduction of boiler feed water on the steam generation process; and, to facilitate the introduction of chemicals for treatment purposes as well as the removal (blowdown) of impurities.

The following document, courtesy of Magnetrol and Orion Instruments, provides information identifying key areas in the steam generation cycle, condensate recovery system and waste heat recovery process where cost-effective instrumentation solutions offer a tangible return on investment over the short term. The goal is to reduce heat rate, environmental impact, fuel and water consumption, water treatment and maintenance costs in commercial and heavy industries where steam generation is essential to the production processes.

We hope you find this white paper interesting and of value.

Using Mass Flow Controllers for Better Wine Making

mass flow controllers in wine production
Mass flow controllers
assist in
making better
quality wine.
Oxygen is the enemy of wine. Unfortunately, oxygen is found commonly in the air all around us. Exposure to oxygen influences wine quality, stability, and longevity. During production and bottling, limiting exposure to oxygen ensures better quality and a more consistent product. 

Nitrogen gas, because of its low solubility and ability to prevent oxygen from contacting the wine, is used widely throughout the wine industry. It is used to purge, flush, sparge, and blanket wine at its various stages of production.

Sparging is the process of injection a gas into a liquid through the use of aerators, bubblers, carbonators, diffusors or injectors. The wine industry uses sparging to inject nitrogen into wine as a means to control the wine's dissolved oxygen and CO2 content. The process of sparging is based on the application of a scientific principle (Henry's Law) which states that the solubility of a gas contained in a liquid is directly proportional to the partial pressure of that gas in the gaseous atmosphere in contact with the liquid.

Careful control of nitrogen is critical to controlling the oxidation processes that determine the subtle variations in wine taste and aroma.  In white wines, sparging with nitrogen is helpful to remove dissolved oxygen. However, the same nitrogen sparge may strip CO2 below desired levels and change the wine's freshness and taste. In some red wines it's important to retain a small amount of dissolved CO2, so tight control of the nitrogen sparge has to be considered.

The efficiency of sparging is determined by several variables, such as:
  • Bubble size
  • Contact time between the gas and wine
  • Temperature of the wine
  • Gas pressure
  • Flow rate of gas in relation to the flow rate of wine

The benefits of controlling the sparging processes to tighter tolerances are becoming apparent. There is a rising need for more precise flow control in sparging applications, and for products that measure the sparged gases and control the flow rates. Accurate mass flowmeters and controllers are being applied more and more.

Products such as the Brooks SLA5800 Series Mass Flow Controllers offer high accuracy over a wide range of flows and pressures, and the SLAMf Series Mass Flow Controllers & Meters provide the control, range, and environmental protection perfect for these applications.

Rupture Disc Relieves Unsafe Internal SF6 Pressure on Electrical Switchgear

Electric switchgear
Electric switchgear use rupture discs
In an electric power system, the equipment used for switching, controlling and protecting the electrical circuits and equipment is known as switchgear.  In general it's the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear controls the switching on or off generators, transmission lines, distribution components, and other electrical equipment.

Gas-insulated high-voltage switchgear, using SF6 (Sulphur hexafluoride), is metal enclosed switchgear consisting of high-voltage components such as circuit-breakers and disconnectors. SF6 is used because of its outstanding electrical, physical and chemical properties. Typical places where this switchgear is used are buildings, on offshore platforms, industrial plants and power plants.

Manufacturers of electrical switchgear use rupture discs on cabinets where conductors and contacts

are insulated by pressurized SF6 gas.

Within switchgear housings, very large amounts of energy are released in the form of heat and even radiation. This energy may give rise to pressure increases which may burst the enclosure unless the heated gases are given the possibility to ow out through relief openings. In the event of an internal fault, a pressure relief device would operate before internal pressure exceeds the design limit of the compartment. The pressure relief device should be designed so that discharges resulting from internal faults are directed away from locations where personnel may be present.

Experience is Key When Applying Custom Electric Heating Elements

Electric Heater Design Expert
Heater design expertise is
readily available from your
Technical Sales Rep
Designing and applying custom electric heating elements are best completed and accomplished through the proper application of the right resources. One of the most available and important sources of high level technical knowledge is a vendor's local Technical Sales Rep. Their assistance is readily available and their consultative value is very high.  Bringing in a Technical Sales Rep will have a big bearing on a successful task or project completion.

Many Technical Sales Reps are degreed engineers. If they don't have an engineering degree, you'll find they have years of empirical application knowledge from working on many, many projects. You'll also find that many have worked at manufacturer's factories and know the in's and out's of production as well as anyone.

Consider these elements the Technical Sales Rep brings to your thermal system design project:

Custom heating element
Watt densities? Thermal profiles?
Distributed wattage?
There's a lot to know.
Product and Application Knowledge: Your Technical Sales Rep has probably seen hundreds, if not thousands, of custom heating requirements. They deliver a mental encyclopedia of product offerings, application insights, and broad spectrum of capabilities. They also have information regarding what products are in development that can give you the competitive edge. Much of this information resides in the Reps head, and is not generally accessible to the public via the Internet.

Experience: As a project engineer, the selection and incorporation of a new heater design may be all new to you. You may be treading on fresh ground with little or no experience in the nuance of electric heaters. There can be real benefit in connecting to a knowledgeable source, with years of past design and application experience, that will save you time, money, and effort.

Access: Technical Sales Reps work closely with a variety of manufacturers, and may even have in-house prototyping or manufacturing capabilities at their own companies. This gives you, the design engineer, a connection to “behind the scenes” manufacturer contacts with essential information not publicly available. The technical sales rep knows people, and makes it his/her business to know the people that can provide answers to your electric heating and custom thermal system application questions.

So, in this age of doing your own research and self-educating on the Internet, let's not forget the importance of a face-to-face visit with someone who can really help - your Technical Sales Rep. You'll be very pleased with the information they can provide to make your job easier and the quality of your product better.
