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.

CRN CERTIFIED PROBES FOR PROCESS SPECTROSCOPY

Several GUIDED WAVE probes and flow cells have Canadian Registration Number (CRN) certification. A CRN is a number issued to the design of a pressure vessel or fitting by each province or territory of Canada. The CRN identifies that the design has been accepted and registered for safe installation and use. 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. Guided Wave currently has 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 designs include hydrotest and x-ray test results.
