Bulk Solids Moving-Bed Reactors, Direct and Indirect Heat Exchangers, Gravity Dryers and Conditioning Columns
Thursday, September 18, 2014
1:00 pm CDT
All registered attendees will receive a certificate of completion.
Processing of bulk solids frequently takes place in fluidized beds or agitated tanks. These technologies are usually capital expensive and have high operating and maintenance costs. Why not consider a moving-bed process vessel?
Moving-bed process vessels are hoppers, bins, or silos modified to allow processing of a bulk solid such as heating or cooling, conditioning, drying, and conducting a chemical reaction. Compared to other fluidized beds and agitated tanks, moving-bed process vessels offer several advantages. They have no moving parts, and therefore capital, operating, and maintenance costs are relatively low. In addition, they offer surge capacity, eliminating the need for a hopper, bin, or silo for surge capacity or storage.
This seminar will discuss critical aspects of the design and operation of processing vessels.
Viewers Will Learn How to:
- Obtain uniform solids flow, and if required, uniform gas flow
- Ensure that the outlet of the processing vessel is large enough to prevent the development of flow obstructions and provide the required discharge rate
- Select gas distributors if necessary
- Choose between direct and indirect heat transfer to the bulk material
- Project and Process Engineers
- Research and Development Engineers

Support & Troubleshooting
What support is available for users on Macintosh and Unix/Linux-Based operating systems?
This presentation incorporates advanced multimedia features that allow elements such as slides, polling questions, surveys, and application demonstrations to be dynamically sent to the audience synchronized with the presentation. Mac and Linux audiences may view the presentation using a supported Firefox Web browser and Adobe Flash player. Please note that some presentations may not feature a Flash option.
Why can't I hear audio?
What is a pop-up blocker and how do I disable it?
- If you have internal speakers, make sure they aren't muted.
- If you have external speakers, make sure they are powered on and aren't muted.
- Make sure you did not lose Internet connectivity.
- Make sure your system has passed the system test located under "Test my system now".
- If your system is using Adobe Flash Player and you receive a "connection failed" message it's most likely due to a proxy server blocking Flash streaming. Please contact your local IT admin.
- If you are using a mobile device, such as an iPhone, make sure you have enough bandwidth. We advise using dedicated wi-fi or 4G.
- If you are using an Android device, Apple iPad or iPhone you will need to click on the media play button to begin the presentation. Android and Apple iOS devices do not permit streams to begin automatically.
- If you are using a PC or Mac please ensure that your browser zoom level is set to 100% as the presentation is best viewed at that setting. In most browsers you can use Ctrl + 0 to reset your zoom level. This option can be also be found in the tools or view menu.
Pop-up blockers are software programs that stop unsolicited "pop-up" browser windows from launching automatically. These windows often feature advertisements that can be an annoyance to users trying to browse the Internet, however some features of the Webcast may make use of pop-up windows to deliver key functionality. Depending on the software progam you have installed you may be able to add the Web site URL to a list of permissible Web sites where pop-up windows are allowed.
It is common to have one or more pop-up blockers that you may be unaware of. Most pop-up blockers reside either in the system tray (lower right hand corner of your screen by the clock) or as a toolbar in Internet Explorer (at the top of your browser, go to "View" and then "Toolbars"). These can be disabled in their options or preferences menus. (Common toolbars such as Google and Yahoo Companion have built in pop up blockers).
Also, if you are unaware of any other pop-up blockers that are running on your computer, you may want to see if you have personal firewall software running, such as Norton's Internet Security or ZoneAlarm. If you have either of these, they will also block pop-up windows.

I occasionally hear a clicking noise during the presentation. How do I turn it off?
Why do I get a "connection failed" or "connection blocked" message when I try to view Adobe Flash streams?
- Windows 7 - Click on the Windows Start icon, then choose "Control Panel" > "Sound," > "Sounds" tab. Scroll down the "Program" menu until you reach "Start Navigation." Set the sound to [None] and click "OK." The clicking will be disabled.
- Windows Vista - Click on the Windows Start icon, then choose "Control Panel" > "Sound," > "Sounds" tab. Scroll down the "Program" menu until you reach "Start Navigation." Set the sound to [None] and click "OK." The clicking will be disabled.
- Windows XP - You can disable this noise by going to the Start menu, then "Control Panel". Open "Sounds and Audio Devices," and click the "Sounds" tab. Scroll down the "Program Events" menu until you reach "Start Navigation." Set the sound to [None] and click "OK." The clicking will be disabled.
In addition to having a properly installed Adobe Flash Player your pc must permit rtmp (over port 1935) and / or rtmpt (over port 80) live streaming protocols. Please contact your local IT Administrator if you are unsure of your settings. IT Admins can click here to review additional information on configuring proxy servers to permit live Flash streaming.
