4 Chemical Processors Improve Operations with Wireless Instrumentation

In this post we have shared the stories of four substance industry peers who executed remote instrumentation arrangements and accomplished picks up in productivity, energy efficiency, reliability and safety.

Know how wireless technology offered these synthetic processors a pragmatic, prudent way to more prominent process knowledge and enhanced operations.

1 - INCREASING PRODUCTIVITY

AkzoNobel, a main worldwide paint, coatings and claim to fame Chemicals Company, relied upon administrators to control steam stream and read gages physically at one plant to guarantee natural direction consistence and item quality.

Infrastructure and I/O constraints left little alternative to these manual solutions. AkzoNobel had to look beyond traditional wired methods to capture and report critical data.

Including remote/wireless instrumentation gave administrators new bits of knowledge into the procedure by giving the required and basic information constantly. This wiped out dreary more established strategies, arranging for administrators to perform more helpful errands.

2 - SAVING ENERGY

A major silicone manufacturer in the Northeast United States uses steam in many parts of its plant, but consumption was increasing without corresponding production improvements. Where was it all going?

Existing stream instrumentation was not giving solid data and was an upkeep cerebral pain. A significant number of the gadgets were likewise sent in inadequate areas.

Adding improved flow meters using wireless communication provided the precision data necessary to get steam consumption under control.

3 - AVOIDING DOWNTIME

INEOS Köln GmbH is a global plastics manufacturer, producing a variety of resins and forms. In its Cologne, Germany, plant, it moves polyethylene pellets using pneumatic conveyors. 

Keeping up item virtue requires sifting the passing on air, yet the channels are liable to stopping up. Manual channel observing by administrators couldn't ensure that blockages would be seen before they influenced gear productivity.

Working in a zone where radio correspondence was testing, the plant required some persuading that remote would be dependable. At the point when the new brilliant remote transmitters were introduced and immediately shaped a system to send information back to the control framework, they were in a split second consoled.

4 - ENSURING SAFETY 

FH Tank Storage in Kalmar, Sweden, operates a large fuel and petrochemical storage tank farm, with products constantly moving in and out of the facility. Inventory and spill control was largely a manual process, with operators checking levels visually. 

Safety regulations and potential for personal injury, especially in the winter, called for a more automated system, but the size of the facility made traditional wiring a hugely expensive proposition.

Finding a wireless solution using a minimum number of level instrument types provided the means to solve the problems with minimal cost and operational disruption.

The plants profiled in this post used wireless technology to improve upon their existing measurement solutions. By investing in the benefits of wireless, their improvements were more cost effective than traditional wired solutions, and caused minimal disruption to existing operations.

Wireless technology allows plants to implement devices one at a time, or in one unit at a time, with each delivering immediate benefits and a quick return on investment. As more solutions are added, information from each can be combined to yield additional insights and further improve operations.

What is PLC? - A Beginner's PLC Overview Every PLC Beginner Should Know

This blog post is for beginners who are interested in learning about PLC and SCADA, but they are confuses or not sure where to start. After read this post you will be able to identify the most basic components of a PLC system and can also know about the basic purpose and function of PLCs (and PACs). In this post I have cover all the basic about PLCs (and PACs).

What is PLC?

PLC stands for Programmable Logic Controller or programmable controller are small industrial digital computers which have modular components designed to control the manufacturing processes. PLCs are often used in factories and industrial plants to control light, motors, fans, pumps, circuit breakers and any other activity that requires high reliability control and ease of programming and process fault diagnosis. To understand the purpose of PLCs better, let’s look at a brief history of PLCs.

History of PLC-

Industrial automation started well before PLCs. In the right on time to mid 1900s, automation was typically done utilizing muddled electromechanical communicate circuits. Be that as it may, the measure of relays, wires and space expected to make even straightforward automation was risky. A large number of relays could be important to robotize a basic industrial facility process! Furthermore, if something in the intelligent circuit should have been changed?

In 1968 the first programmable logic controller came along to substitute complex transmit circuitry in industrial plants. The PLC was intended to be effortlessly programmable by plant architects and specialists that were at that point acquainted with transfer rationale and control schematics. Since the starting PLCs have been programmable utilizing stepping stool rationale which was intended to imitate control circuit schematics. The stepping stool graphs look like control circuits where control is spilling out of left to directly through shut contacts to empower a hand-off loop.

In the above diagram, you can see ladder logic looks like simple control circuit schematics where input sources (switches, push-buttons, proximity sensors, etc) are shown on the left and output sources are shown on the right.

How Do PLCs Work?

There are many PLCs components, but only these below three are most important of them:

1. Processor (CPU)
2. Inputs
3. Outputs

PLCs are most complicated and powerful digital computers but here we can describe the function of a PLC in simple terms. The PLC takes inputs & performs logic in the CPU and then turns on or off outputs based on that logic.

1. The CPU monitors the status of the inputs (ex. switch on, proximity sensor off, valve 40% open, etc.)
2. The CPU takes the information that it gets from the inputs, performs logic on the inputs
3. The CPU operates the outputs logic (ex. turn off motor, open valve, etc.)

See the flowchart below for a visual representation of the steps above.

Conclusion: Now you have better understanding of what PLCs are and how they work. Now you can start your PLC course. This was basic concept and was most important to know before start PLC training.

The future of Industrial automation PLC SCADA technologies

Every industrial automation PLC SCADA project starts with the familiar process of counting I/O, selecting vendors, laying out PLC chassis, and distributing requests for quotes. And finally you are commissioning a system built on general standards, repeating the same mistakes as previous systems.

The conversations also repeat during bid review or negotiation meetings when someone points out inconsistent or outdated standards. Technology is changing so fast, and the past few years have brought technical advances that have breathed new life into Industrial automation groups and started great discussions around what the future holds. There is still a lot of work to be done.

Virtualization is a great example. Early adopters saw the benefits, and news spread like wildfire. As SCADA (supervisory control and data acquisition), manufacturing execution systems, and historian capabilities increased, so did the need for processing power, and virtualization was the perfect answer. Virtualization is now commonplace in Industrial automation domain. And many are asking what is next. The next big thing is waiting to happen. Industry has become more demanding asking for virtualized controllers and solution with mobility. But they are easily feasible with existing technology. The success of our industry depends on it.

HMI/PLC SCADA industrial automation applications have already secured their place as key components for any smart factory, IT-focused applications. Humans by nature are reluctant to give up control; however, fully automated facility does not mean a complete end of human interference on the factory. Considering the huge focus in industrial automation / automated equipment and intelligent HMI/PLC SCADA software, it is important that manufacturers invest in employee training, enabling talented engineers from industrial automation domain to focus on important tasks.

What is Industrial automation & how it evolved

What is industrial Automation

Industrial Automation is a technique by which we make hand over human control to machines. In industrial automation machines are programmed to accomplish the tasks which human beings used to achieve. Why it is done? Because of its advantages:

• Through Industrial automation we are able to do mass production with less manpower

• Quality of the product is increased
• Safety of man & equipment is increased
• More accurate process control
• Since human intervention is less so reliability of the system is higher
• Systems operate is low power supply, more electronic control so equipment life is higher
• Changes in process logic becomes easier since logics are changed mostly through software

How industrial automation control system Evolved?

Initially automation was achieved through manual control, operators used to control the process at every step. Human intervention was there at every step. Drawbacks were low quality output, errors involved in human involvement affected compromised safety, wastage of raw material, and accuracy of human action.

Then came Pneumatic Control: Industrial automation in this era was achieved through invention of pneumatic controllers in early 1920s. Automation was achieved by controlling air to pneumatic valves, which in turn were actually switched on/off by relays and switches. They were very bulky and changing of the logic was very complex procedure since a lot of rework was required to accomplish change in logic. So time taken to complete task changes was very high  

Hard wired logic control: contactors, relays (for switching), timers and counters (for timing and counting) were used for achieving desired industrial automation. But these systems also resulted into bulky panels. A lot of wiring was involved so time taken to complete task was higher. Defect investigation & troubleshooting was complex.

Electronic Control using Logic Gates: In early 60s electronics dominated the process, electronic logic gates were used for achieving logical operations. they replaced switching devices like relays and contactors in the control circuits. Electronic times & counters replaced mechanical timers & counters. Due to use of electronics space and energy requirements reduced, maintenance requirement reduced & systems were more reliable.

Psychometric study and HVAC design and drafting

Psychometric study is a vast science and an integral part of HVAC design and drafting, MEP (mechanical, electrical and Plumbing). Psychometric means study of air properties. In literal sense of Air conditioning, air is the aspect to deal with. This air can be Supply air (SA), Return air (RA), Fresh air (FA) and Extract air(EA). SA and RA contribute to maintaining the temperature of the room as per the human comfort. FA and EA signify to the ventilation part. The outside air i.e. the ambient air varies from city to city and from variant time zone. The inside temperature or the desired temperature is universally considered to be between 21 deg C to 26 deg C; ideally 23 deg C. This indoor temp is universally accepted temperature range which is considered satisfactory for human comfort. Other factors which influence human comfort in HVAC system include the metabolic rate of the individuals, their physical activity, health conditions, clothing, food and drink etc. Generally speaking it is associated with individual metabolism rate which produces heat.

Psychometric analysis does not only signify to the temperature aspect but also to at Relative humidity ie RH and that means % of moisture content in air. For HVAC design and drafting, basically there are five major aspects:

• Dry Bulb Temp
• Wet Bulb Temp
• Dew Point Temp
• Relative Humidity
• Humidity Ratio

The preparation of psychometric table in HVAC design and drafting leads to the Heat Load Calculation which makes sure how much heat in unit of BTU/Hr needs to be dissipated and against that how much cooling in terms of TR needs to be entertained in the desired location. 

A Psychrometric Chart is very important tool for HVAC engineers which helps them to carry out heat load or cooling load calculations. This also helps HVAC design and drafting engineers find solutions to various air condition related problems. The psychrometric chart in overall shape looks like a shoe.
