Project Engineering Of Process Plants Howard F Rase Pdf Printer
Please bear with me, as I am *just* getting started creating the project, backfilling information, and everything else. I hope to spend the next 5 days fleshing things out. Todo: 1) Get dokuwiki running on my home server. Install a good theme, flesh out the link/file structure and organization. 2) Write background pages on the Bosch-Haber process, and other possible processes and reference material. 3) Write up a project roadmap - what steps to take in what order 4) Come up with an appropriate project image • at 02:57 •.

Some surprising (to me, anyway) developments. I had originally planned to build an ultrasonic power supply with plans, schematics and whatnot, and come to find one on eBay for $50. This unit will supply 385 watts, which is much more than the 50-watt unit I had planned to build. And it will save me hours of designing, testing, and building. After discovering that there are several names for what is essentially the same thing (thank you, eBay!), I redid my literature search and found titled 'Sonochernical Fixation of Nitrogen' where a graduate student at Ottawa does much of what I am proposing to do. I haven't had time to read the paper in detail (only skimmed), but from a first impression of his experimental setup I'm guessing that he is not using a very high energy density (ie - the watts per square cm of his sonification is low), and he's sparging the gasses through a frit instead of using a pass-through probe with concentrator.

(It means he used a sort of aquarium air stone to bubble the gasses up through the solution. I didn't know either, I looked it up.) So it *may* be that I'm looking in places where people have looked before, which means that my probability of success has dropped dramatically. My original plan was to design a hobbyist-grade ultrasonicator that could be used for home sonochemistry experiments. That's a pretty interesting project in its own right, and I've always known that it's unlikely that I'll find anything. Maybe in a few months will be the first 'hackaday prize' entry featured as a 'Hackaday Fail':-) • at 22:56 •. I've had a chance to look over Supeno's paper in detail.
Quickly summarizing his results: Ammonia and various nitrate compounds (depending on supplied gases) are formed when the gases are bubbled up through water and sonicated. The rate of formation is very low, in the neighborhood of nanomoles per minute per watt, depending on reaction and conditions. Other papers report similar rates of formation, with results ranging from tenths of nanomoles to micromoles per minute per watt (pages 9-11 in the referenced paper). This is actually good news. If no researcher had seen formation of nitrates or ammonia in sonication experiments, this would mean that some fundamental principle invalidates the model.
Since some formation was seen, then the model is correct at some level. Additionally, the wide range of results (nanomoles to micromoles per watt) indicates that the model is dependent on experimental conditions, and this opens the possibility that the model could be explored in creative ways. That said, a hobbyist-grade sonicator in the 50-100 watt range is an interesting project in it's own right, so I'm still intending to build one of those, and publish the designs.
====== Ultrasonic transducers (normally used in cleaning baths) with power output up to about 120 watts are common on eBay, at a cost of about $20 - $50 depending on vendor and power. That's about right for a hobbyist unit, it's easily available, and shouldn't require extreme electronics for the driver (I think). So I'm thinking: one of these transducers inside an H-bridge driver, a two hundred volt DC power supply, a microcontroller to generate frequency and control power, and a machined horn to transfer energy to the reaction chamber. A small sonicator could be used for other hobbyist purposes such as plastic welding, cleaning, (possibly) spot welding, cell disruption, drilling, and probably a bunch of other things I'm not thinking of. So even without the Nitrogen aspect, it's still an interesting project. To me, at least. • at 00:24 •.
