    Double_Conical_Dryer_Case_Study_current_design-after_revampingGlass-lined double conical dryers are a workhorse in the pharmaceutical and fine chemical industries, with a rigorous design that enables them to run for decades.  A common issue with these units, however, is the vessel's cleanability.  Enhancements are available that provide revamping possibilities that will improve not only the cleanability and filtration process, but will also significantly reduce the maintenance cycle time. This blog post features a case study that illustrates how an upgrade to the dryer vacuum tube can accomplish all of these improvements.

    Introduction to Agitated Nutsche Filter/Dryers

    moz-screenshot-30maxh=447,maxw=250,h=447,w=250The agitated nutsche filter/dryer is a multipurpose piece of equipment that you can find in a wide range of industrial processes.  Often found just downstream of a reactor or crystallizer, it has the important job of separating and isolating solids from a solvent.  It has certainly come a long way since its beginning, when the nutsche filter design consisted of an open vessel that simply used suction to achieve separation.  Modernization by Rosenmund started in the 1960’s, when the vessel design was enclosed for containment, enabling the introduction of pressure and agitation.  The closed system further allowed for process control on parameters like temperature, pressure, pH, and agitation.  In addition to expanding the unit’s operations, containment helped to protect operators from product environment as well as isolate the product from the atmosphere.

    DDPS Aftermarket Series:  Spotlight on Spare Parts [Part 3]

    Posted by Jennifer Mayo

    Apr 18, 2019 2:41:00 PM

    QVF vesselsAftermarket sales play a huge role in the life of your chemical process equipment.  When you spend the time and money to purchase a solution from a systems provider such as DDPS, there is a level of service and support that you come to expect when making an investment of this magnitude.  We're here to help you extend the life of your equipment and keep your system running safely and efficiently.  

    The rigorous operations that most of your equipment undergoes makes it essential to keep spare parts on hand to help minimize downtime when service has to be interrupted for routine maintenance or part replacement.  In part 1 of this series, we talked about how to determine what spare parts you should have on hand.  In part 2, we discussed how to go about ordering a part and tips for identifying the part number of a QVF glass component.  In this third and final post, we'll tell you a little about our stocking programs and how you can benefit from enrolling your equipment.

    QVF glass markingIt's one thing to identify a part that you want to order (read our post on determining what spare parts to have on hand), but it can sometimes be challenging to figure out what information you need to get that part ordered.  De Dietrich Process Systems' Aftermarket Representatives are always on standby to help out with this, but we've also created some tools to make it easier for you to identify the information we need to provide you with an accurate quote.

    moz-screenshot-172maxh=135,maxw=250,h=276,w=510Whether it’s household appliances, cars, or industrial equipment, most products require some additional expenses after the initial purchase.  Parts can become worn or damaged and need to be replaced due to rigorous operation or even simple, every day use.  Even if you have your equipment routinely serviced and you meticulously care for it, it’s just the nature of things –nothing is made to last forever.

    Bridging the Gap Between Development and Piloting with Jacketed Reactors

    Posted by Jennifer Mayo

    Jan 10, 2019 4:16:03 PM

    Jacketed Reactor SystemTraditionally, manufacturing processes are initially developed in round-bottomed laboratory flasks and are then transitioned to small-scale production-type reactors once the process is ready for piloting.  QVF laboratory-scale jacketed glass reactors (also referred to as “miniplant reactors”) offer a unique alternative that features a vessel more similar in design and function to production-size reactors.  In this post we’ll discuss the five main advantages of utilizing glass-jacketed reactors for development to scale-up testing and how they could potentially benefit your company.

    The Modernization of Chemical Plants

    Old QVFIf you were a chemical engineering major in college like me, most of your time in school was probably consumed with writing lab reports, solving complicated math problems, and completing copious amounts of physics and chemistry homework.  My curriculum did require a few humanity classes (I guess to diversify the repertoire of the engineering student’s workload), but little time was spent learning about the actual history of chemical plants.  Don’t you think it would have been interesting to take a “Chemical Plants History” class?
