Keit announces plans for ultrasonic descaler for the IRmadilloDiamond

Improving performance of industrial process analyser in chemically scaling processes

Oxford, United Kingdom 

Keit is pleased to announce plans to incorporate ultrasonic descaling into its product offering as a means to keep the IRmadillo process analyser operational in chemically scaling environments.  

Many industrial processes involving inorganic salts and compounds have inherent scale formation – for example, gibbsite formation in alumina refining, or pirssonite formation in pulp making. ATR (attenuated total reflectance) based analytical instruments have traditionally been susceptible to fouling and scaling, rendering them unsuitable for these environments. Keit has demonstrated that the use of ultrasound – typically in the range of 20,000 to 40,000 Hz – effectively removes scale from the ATR of the IRmadilloDiamond probes.  

This exciting development means Keit will be working with third-party suppliers of ultrasonic equipment to create an all-inclusive solution for incorporation into an IRmadillo installation suited to a wide range of environments. Initially this will be focused on process monitoring of alumina refining and pulp manufacturing, but has implications for all metals, mining and minerals (MMM) applications, as well as extending to removing biofilms during monitoring of industrial biotechnology applications. 

About Keit Spectrometers and the IRmadillo Analysers

Used around the globe, Keit has created the family of IRmadillo mid-infrared instruments to provide in-line, in situ process analysis of liquids over a variety of operating environments. Built tough with fixed sampling probes and a vibration-tolerant optical design, IRmadillo process analysers enable real-time analysis of liquids in environments that challenge standard instrumentation.

TAPPI Webinar Keit Spectrometers Jan 2022

Power of spectroscopy in chemical recovery & stickies monitoring

TAPPI Webinar January 18, 2022

Is there a way to improve chemical recovery through more powerful on-line monitoring techniques? How would you monitor the development of stickies in your process in real time with current technologies? Do you want to discover how this area of analytical techniques have adapted and attempt to achieve real-time analysis for better production insights?

Spectroscopy has the power to directly observe chemicals present in a sample. Monitoring chemical concentrations from on-line analysis is recognized as having the potential for significant impact on chemical recovery efficiencies as well as accuracy and speed of stickies monitoring. However, not all spectroscopies are the same. Join Keit’s Product & Application Manager, Dr. Jonathon Speed, at the upcoming TAPPI webinar January 18, 2022 as he presents a thorough comparison & contrast of on-line spectroscopies of the three major types of industrial techniques available to pulp and paper manufacturers – near-infrared (NIR), standard Fourier transform infrared (FTIR or mid-infrared) and the IRmadillo FTIR (innovation in mid-infrared).

Find out about the possibilities with technology and techniques for on-line monitoring of the top challenges in pulp & paper production.

High-Temperature IRmadilloDiamond

Keit’s Newest High-Temperature IRmadilloDiamond for Monitoring Processes up to 220°C (428°F)

Rugged industrial FTIR process analyser with increased temperature compatibility 

Oxford, United Kingdom

Keit is pleased to announce the release of its high-temperature IRmadilloDiamond analyser for liquid processes up to 220°C (428°F). The in-line, diamond-ATR instrument has been designed to provide continuous, real-time analysis of processes over a wider range of analyte temperatures for faster monitoring and control of industrial processes.

Industrial Process Monitoring Technology

Dan Wood, CEO, Keit stated “The IRmadilloDiamond is a robust mid-infrared analyser. It performs over a full pH range and can be installed directly into production lines with analyte temperatures ranging from ‑20°C up to 220°C. This makes it ideal for industries such as Pulp and Paper that operate with high-temperature processes under similarly harsh conditions. It’s a challenge for them to find real-time analytical techniques that work”.

Dan elaborated “We’ve been working with several pulp mills in the analysis of green, white and black liquor streams in the kraft process. We’ve successfully proven the ability to monitor key components that affect the safety and efficiency of the recovery boiler and the recausticing process with the aim of improving the efficiency of the chemical recovery process. The IRmadillo can help them achieve real-time monitoring”.

“Another industry that benefits from the high-temperature IRmadilloDiamond”, continued Dan, “is the alumina refining sector where conditions are brutal on standard monitoring instrumentation. The rugged IRmadilloDiamond gives alumina refiners immediate concentration analysis of such chemicals as caustic soda. Being able to measure this throughout the refining process allows for better control of chemical addition. It minimises waste, reduces energy consumption and improves production efficiency to reduce costs”.

IRmadillo and Industry 4.0

Dan concluded “But the appeal of the IRmadilloDiamond’s higher temperature range also applies to other industries including bulk and specialty chemical manufacturers. In the end, as all of these industries align themselves with Industry 4.0 principles, the IRmadilloDiamond is the process analytical technology that allows them to move their monitoring in-line with production processes for real-time analysis and improved control”.
