Canadian Registration Number (CRN) Certified Probes for Process Spectroscopy

A Canadian Registration Number (CRN) is a number issued to the design of a pressure vessel or fitting by each province or territory of Canada. The CRN identifies the design has been accepted and registered for safe installation and use. As of October 2019, Guided Wave has submitted more than 3,500 different design configurations for our probes and flow cells to be CRN certified.

CRN certified probes and flow cells are engineered by Guided Wave to meet the strict safety and application requirements for the Canadian petrochemical, refining, and polymer markets. By coupling these probes with certified (CSA, ATEX, IECEX) process analyzers, Guided Wave can offer complete process monitoring solutions to Canadian customers. We currently have CRN registered designs for Ontario, Alberta, and Quebec. However, complete process monitoring solutions for all provinces can be implemented – contact us for more information.

All CRN probe sales include hydrotest and x-ray test results.

Feasibility Study: Styrene, Acrylonitrile and Methyl-ethyl-ketone (MEK) for Online Control on a Styrene Tower

water cooler bottles

Styrene acrylonitrile resin, known as SAN, is a copolymer plastic consisting of styrene and acrylonitrile. Due to its superior thermal resistance, it is widely used in place of polystyrene. By weight the relative composition is usually 70-80% styrene and 20-30% acrylonitrile. Mechanical properties and chemical resistance of SAN can be improved with a larger acrylonitrile content, but the compromise is a yellow tint to the normally transparent plastic. Product from this plastics family includes food containers, water bottles, kitchenware, computer products, packaging material, battery cases and plastic optical fibers. Styrene gives the plastic a nice glossy finish. Styrene revenue is projected to increase at a compound annual growth rate (CAGR) of over 9% from 2019 to 2025, according to the Global Newswire network. They report an increased demand in the manufacture of various products, using acrylonitrile butadiene styrene (ABS), expanded polystyrene, and polystyrene as the contributing factors.

Getting the correct blend of copolymers to achieve the desired physical properties can be a challenging task for process engineers in the polymer industry. Near-infrared (NIR) spectroscopy is a convenient and cost-effective tool for monitoring reaction processes in situ to ensure that the correct chemical ratios, average molecular weight, and physical properties are within specifications.

When transparency is a concern, the process engineer has several options. If polystyrene’s mechanical properties are insufficient, the process engineer can tailor a specific formulation of styrene-acrylonitrile copolymers or SANs (Figures 1 and 2). These copolymers typically contain between 20–30% acrylonitrile. Due to the polar structure of acrylonitrile, SANs copolymers have better resistance to breakdown in hydrocarbon streams than polystyrene. SAN copolymers also have a higher softening point, rigidity, and impact strength, yet maintain their transparency.

Figure 1. Molecular Structure of SANs
 Figure 2 Molecular Structure of Styrene, Acrylonitrile, and MEK
Figure 2 Molecular Structure of Styrene, Acrylonitrile, and MEK

As the acrylonitrile content of the SAN copolymer is increased, there is an improvement in the toughness and chemical resistance. The trade-off is a greater difficulty in molding and potential yellowness of the resin. SANs copolymers are also used in polyols processing to strengthen other polymer types. Monitoring stream composition during processing allows manufacturers to maintain product quality.

By incorporating a near-infrared (NIR) spectrometer and in situ process probe, a process engineer can quickly identify when the mixture of component concentrations are out of specification. The NIR region of the electromagnetic spectrum measures the overtone and combination bands of the C-H, O-H, and N-H fundamentals absorption bands. These spectra are unique to the molecule thus permitting the process engineer to make real-time corrections and ensure that product quality is maintained. In the case of SANs, NIR spectroscopy can be used to monitor the concentration of Styrene, Acrylonitrile, and MEK molecules

Today the use of DG-NIR analyzers continues to improve the accuracy and speed of measurements for polymer feed concentrations that can be achieved with both Guided Wave analyzers; the NIR-O full spectrum NIR analyzer or the ClearView db photometer. By collecting these data, process engineers in the polymer plant can make informed decisions on process optimization to ensure product quality.  

The proof of concept study presented in this application note illustrates that Guided Wave process analyzers can detect changes in concentration as little as 0.1 %wt.

Fast Reliable Measurements of Polyurethanes

polymer products raw materials

Polyurethane was first developed as a replacement for rubber at the beginning of World War II. Because it was a versatile substitute for scarce materials the applications for this new organic polymer increased rapidly. This trend remains evident today, as processing techniques continue to be developed, and new formulations and additives created, polyurethanes can be found in virtually everything we encounter. From apparel to appliances, marine to medical, polyurethanes are used to create cost-effective, comfortable, supportive and long-lasting industrial and consumer products.

polyurethanes adapt for challenging problems

The nature of the underlying chemistry allows polyurethanes to be adapted to solve many challenging problems. Consequently, production of all types of polyurethanes is greatly expanding worldwide with customers like INEOS, Evonik, BASF, Wanhua and Indorama. With this growth, measurement and control are more important than ever in meeting business production goals. Many aspects of polyurethane production can be measured using near-infrared (NIR) spectroscopy including the measurement of OH number of polyols. When considering final product measurements, polyurethanes can really be considered to be an amide or an ester of carbonic acid (carbamate). The use of remote spectroscopic measurement methods provides analyses in real-time and minimizes the need for performing laboratory measurements. These methods can be applied in reactor systems for control of important properties during the reaction and to determine the endpoint of the reaction thus adding to the value and cost savings. The application note, “Measurements in Polyurethanes” describes the potential uses of Guided Wave hardware and software tools for key measurements in polyurethane production using fiber optic-based NIR spectroscopy.

Types of Polyurethane:

  • Flexible polyurethane foam
  • Rigid polyurethane foam
  • Coatings, adhesives, sealants and elastomers (CASE)
  • Thermoplastic polyurethane (TPU)
  • Reaction Injection Molding (RIM)
  • Binders
  • Waterborne polyurethane dispersion (PUDs)

Custom, Certified, and Compatible – Probes and Flow Cells for EXTREME Environments

Where can you find spectroscopic probes or flow cells in custom designs, certified for strict engineering compliance, compatible with most analyzer manufacturers, and at a competitive price? With average delivery times of 6 weeks or less, Guided Wave’s rugged sample interfaces meet these challenges. Additionally, these probes and flow cells are designed specifically for operation in extreme environments and utilize carefully designed optics, that are among the highest optically efficient designs on the market. 

Probes and Flow Cells for Extreme Environments

Corrosive Material? Doesn’t Matter with this Custom Flow Cell

With a long history of designing custom probes and flow cells to meet specific or unique customer applications and challenges, the toughest (and most expensive) flow cell ever built by Guided Wave was recently released. The reason for the high price is that it is made from B2 Hastelloy®, a rare material used only for the most severe chemical processes. Hastelloy, a nickel alloy, is a more exotic and expensive material than stainless steel typically used for standard flow cell body construction. Hastelloy is usually the best alternative when dealing with an extremely corrosive process stream, and stainless steel is deemed unsuitable for the process.

Pyrophoric Fires a Concern? Extinguish your Worries 

For most customers, our innovative- first in the industry, built-in cleaning port is a welcomed feature of our flow cell. It allows the cell’s sapphire windows to be cleaned by simply removing a clean-out plug. This direct access to the windows without disconnecting process lines or fiber optic cables is convenient and makes maintenance easier and more cost effective. However, a recent customer came to us with a pyrophoric process. Their process cannot tolerate the possibility of the flow cell cleaning port being accidentally opened, exposing the stream to outside air. As a result, Guided Wave designed a new flow cell without the window to relieve safety concerns and to remove the “what ifs?”

Whether standard or custom designs, many Guided Wave probes can be optimized for the UV, Visible or NIR spectral regions or supplied with custom fiber diameters and connectors to match a variety of optical requirements. Guided Wave also supplies probes manufactured in compliance with the American Society of Mechanical Engineers (ASME) or Canadian Registration Number (CRN) pressure vessel standards.

Time to Upgrade Your M412 Analyzer? Key Points Your Proposal Needs to Include

Over 20 years ago Guided Wave debuted the Model 412 near-infrared (NIR) process analyzer (M412). In 2016, with advances in technology and our pioneering experience in the spectroscopic analysis industry, the M412 was replaced by NIR-O. NIR-O provides better performance, advanced operations, and improved ROI.

There are 2 Options for Adopting a NIR-O Spectrometer for Existing M412 Users:

Upgrade M412 to NIRO

1. Retrofit your M412 Enclosure with the New NIR-O Spectrometer

The NIR-O Spectrometer can be retrofitted into any existing M412 installation. Simply schedule downtime for the analyzer, remove the M412 spectrometer and related elements, and follow the retrofit installation guide. Within a few hours, your NIR-O will be up and running in your existing enclosure and properly communicating with your DCS. Contact (link to RFQ) a Guided Wave sales representative to receive a quote for this special Retrofit Upgrade.

2. Purchase a Fully Certified IECEX, ATEX, or CSA Certified NIR-O

The retrofit of the M412 enclosure may invalidate any hazardous environment certifications for the M412. The state-of-the-art NIR-O has model certification for both IECEX and ATEX. Additionally, a CSA field certified design is available. Contact a Guided Wave sales representative to receive a quote to upgrade to a certified NIR-O full spectrum analyzer.  

Cost Reducing Considerations for Upgrading to NIR-O

Compared to new system installations, substantial savings can be realized by either retrofitting the M412 or purchasing a complete NIR-O analyzer system. There are 5 top cost-saving justifications to include in your project proposal. These include the ability to reuse existing probes and fibers, transferability of current chemometric calibrations, enhanced support for modern security protocols, quick adoption due to a minimal learning curve, and a convenient spare parts service plan.

NIR-O Analyzer

Reuse Existing Probes and Fibers

Guided Wave designed the NIR-O to be optically matched with existing M412 fibers, flow cells, and insertion probes. As a result, Guided Wave can offer a more cost-effective upgrade path to existing users. Reusing the probes and fibers from the M412 allows the NIR-O upgrade to be dramatically less expensive.

Keep your Existing Chemometric Calibrations

The chemometric calibration models in use on the M412 can be efficiently updated by Guided Wave staff for use on the NIR-O analyzer system. A calibration update reduces the opportunity cost associated with modernizing your analyzer.

Improve Security via OmniView Software

The Class PA software utilized by the M412 has provided users with years of trouble-free operations. However, security concerns and best practices were completely different 20 years ago. By upgrading to the NIR-O analyzer and associated OmniView software, your IT staff can rest assured knowing that the key analyzer software meets today’s vigorous security protocols.

Library of Online Support Videos and Training Materials

As part of the product launch for the NIR-O, Guided Wave developed a wide range of support videos hosted on our YouTube channel. In addition, we have NIR-O qualified support engineers available to help with startup and other troubleshooting issues.

Spare Parts and the WaveCare Support Program

The NIR-O spectrometer was designed specifically to address the service issues associated with the M412’s input module and shutter assembly. These design improvements have resulted in a dramatic decrease in the amount of service work required, resulting in more uptime for the NIR-O analyzer.  Additionally, an optional WaveCare Support Program was launched in 2019 to provide users with improved lead time on spare parts and service calls to further ensure uptime.

Contact a Guided Wave sales representative to save money and time by either retrofitting your M412 or purchasing a new NIR-O analyzer system.
