Best Practices for Low Volume Mixing in Reactors

Posted by Jennifer Mayo

Jul 26, 2018 11:11:00 AM

glaslock_whiteTypically, when you purchase a glass-lined vessel, you specify it according to the batch size of your intended process.  Sometimes, however, it is necessary (or desirable) to run smaller batches in existing equipment that was designed for much higher volumes.  Low level mixing is also inevitable when your vessel contents require constant agitation, even during emptying of the reactor.  But is it even possible to mix 5 gallons of product in a 500-gallon vessel?  The answer is yes, but there are cautions, rules, and guidelines that should be obeyed in order to successfully accomplish low-level mixing.  In this post we’ll tell you all about them, so you can run your agitator correctly and safely in small batches.

The Ultimate Cheat Sheet for GlasLock Blades

Posted by Jennifer Mayo

Jul 19, 2018 11:34:00 AM

GlasLock - OptiFoilThe GlasLock interchangeable blade system has become the agitator of choice for many of processes that utilize glass-lined steel equipment.  In fact, GlasLock is the standard agitator for our GL series reactors.  What makes this blade system so popular is its ability to be adjusted, removed, and interchanged, a quality that is especially important in processes that can undergo so many changes.  Unlike a one-piece agitator which is selected based on specific process objectives, GlasLock blades can be set to various angles or swapped out for different shaped blades to accomplish different mixing objectives.

Pilot testing imageTesting in the chemical industry, often referred to a pilot testing, can provide great feedback with a much lower risk. It is recommended to run a “pilot test” before making major decisions, especially those who carry a large financial investment for your company.  During pilot testing you are essentially creating a miniature version of a production-scale operation in order to replicate the environment of your process on a smaller scale. The test will help ensure you get the end results you want.

imageVarious technologies are available to improve safety and containment when transferring solid materials into manufacturing processes. 

Going one step further, automated control of these systems can have a significant impact on their operating efficiency, flexibility, reliability and safety.  Since control system designs can range from relatively simple to highly complex, a vendor's ability to offer customized control system designs can be critical to meeting the customer's and the application's specific requirements.

Tackling Sampling in Glass-Lined Steel Vessels

Posted by Jennifer Mayo

May 10, 2018 2:30:00 PM

Recircuating_Samping_SystemObtaining product samples from a glass-lined vessel is not always a simple, straightforward task.  From a quality control standpoint, you want the sample to be accurate and precise.  From a safety perspective, you also want to manage any concerns that can arise when the process involves toxic, flammable and corrosive materials (and if you are using glass-lined equipment it’s a good chance your media has at least one of those three characteristics).  Exposure to the product might be harmful to operators, or the environment could contaminate your valuable product, so multiple factors need to be taken into consideration when selecting the best method for obtaining a sample.

Reactor buyback earth dayAs Earth Day approaches, we are all reminded that there are things each of us can do as individuals to make better choices for the environment.  Maybe it’s using a refillable mug every morning instead of choosing the convenience of a disposable coffee cup.  Public transportation and carpooling are other options that can reduce traffic and emissions.  There are also initiatives that corporations can implement with regards to energy consumption and recycling that can help reduce their environmental impact.

6_API_Kilo-Pilot_Plant_reactormaxh=316,maxw=250,h=450,w=356.jpgMaterial of construction is a primary factor in equipment selection, especially when you are dealing with a product that requires a high level of corrosion resistance and purity.  If that’s the case, then glass and glass lining are most likely among your top choices.  Both offer similar advantages, but there are obvious differences that set them apart.  So how do glass and glass-lined steel compare to each other with regards to overall performance?  In this post we’ll demystify the properties of each of these materials and how they compare to one another.
