If anyone’s curious about our little club, come to a meeting! We’re going to be meeting weekly:
When: 4pm Wednesdays
Where: CHBE 204 or nearby
We’re going to try and do something fun like a movie or tour every other week, starting on the 26th. We’ll be watching Revenge of the Electric Car and have some popcorn. Come chat with us!
Tyler Wood mixing up B20 blend in the fueling station
We’re ready to sell to our first customer. As soon as Student Housing and Hospitality Services has an empty tank, we’ll to fill it up with our B20 blend. We haven’t got a sophisticated blending facility. We just pour the right volume of regular diesel into our tank and circulate it for a while to make sure it’s blended well.
A batch of biodiesel that has too much water in it becomes a soapy, spoiled wreck, and isn’t much use to anyone. Past experience dealing with spoiled biodiesel has gone like this:
Grumbling
Resignation
Pouring the soapy mess back into the containers that held the vegetable oil it was made from
Attaching blue “Flammable Liquid Disposal” tags with barcodes that indicate that the Biodiesel Project is responsible
Hauling the containers down to CHBE Stores, from whence they vanish to Parts Unknown.
Well, where do those containers end up? I decided to find out. I asked the friendly stores clerk, and discovered that chemical wastes on campus are generally dealt with by the Environmental Services Facility (ESF), run by UBC Risk Management. A couple emails later, and I was biking down to the farthest southern part of campus.
The Environmental Services Facility entrance on Nurseries Road.
I thought I was lost, but like the Wizard of Oz, the ESF is just at the end of the road. At the gate, I was met by Mr. Bang Dang and Mr. Valery Kichenko, technicians at the ESF. They gave me a nice tour, demonstrating how they safely collect and dispose of the chemical and biological wastes generated by UBC.
Valeriy demonstrates how chemical wastes are packed in barrels for disposal.
Chemical wastes going for disposal are packed in vermiculite for safe transport to UBC’s chemical waste disposal contractor.
The Solvent Recovery Program’s storage room contains more jerrycans than I have ever seen in one place.
Recyclable solvents are distilled in columns like this one, recovering the reusable acetone and methanol. Spinning-band distillation is also available.
This room contains the ESF’s Silver Recovery Program, where silver is extracted from photography chemicals before disposal.
These five barrels of methanol on the right were donated to the Biodiesel Project by Methanex. Thanks, Methanex!
This styrofoam is bound for UBC’s styrofoam recycling pilot program. It will be melted into a thick goo, which can be cast into new objects like picture frames.
The ESF also deals with biological waste, empty paint cans, propane containers, and more.
Now that we know what happens to a bad batch of biodiesel, we’ll be accumulating it in a drum, rather than multiple smaller containers. This gives us the chance to re-process it into better biodiesel, along with requiring less packaging if we have to dispose of it.
Thank you Bang and Valeriy for the tour, and for all your hard work in safely dealing with and reducing UBC’s chemical waste.
Biodiesel Project Chief James Butler just inadvertently learned how to purge the new fuel filter, and has some clean up to do.
A long-term goal for the Biodiesel Project is to sustain itself financially by selling biodiesel. If we’re going to sell our biodiesel, we need a high-quality product, and we should be able to deliver it safely and consistently. Accordingly, we’ve been developing procedures for testing and delivering our product.
Running a miniature fuel station isn’t something we’re embarking on lightly. There’s a lot of regulations to comply with, and many authorities who might complain that they haven’t approved our project. Keeping track of all the documentation is a challenge just by itself.
ASTM International defines the D6751 biodiesel standard and this is the benchmark we measure our products against. It takes a lot of lab work to test a batch of biodiesel, to see if it meets the standard. Have a look at some of the instruments we use:
The TGA/DSC is a neat instrument that analyzes the weight and heat changes of a sample as it heats it. We currently use it for a crude methanol content measurement, and are exploring measuring biodiesel energy content.
The autotitrator is a useful instrument that dispenses small amounts of liquid and measures the result electronically. We use it to measure the acid and water contents of our biodiesel.
Graduate student Steve Reaume punishes the GC/MS for its insolence. GC/MS is useful for many things, but we use it to examine our biodiesel’s glycerol content.
The rotary viscometer measures a sample’s viscosity by measuring how hard it has to work to turn its spindle inside a fluid-filled cup.
If we’re going to make biodiesel, we’d better have some plan to use it! What do you put biodiesel in? Engines! What do engines live in? Trucks! So we need a good way to get our fuel into trucks.
This week, we suited up in our PPE and spent a day wrestling barrels in CHBE’s outdoor storage cage, clearing a space for our biodiesel dispensing rig. A big thank you goes to Ivan Leversage, for letting us help him sort the place out and then claim a bit of space. The storage cage is really a sort of interesting history of the department, we found one bucket dating from 1999, which pre-dates the existence of both the cage and the building it’s next to!
Another good find while wrestling with the mess was two drums of methanol, which I discovered were donated to the Biodiesel Project in a previous phase of the project. Thanks, Methanex! We’ll put it to good use.
Professor John Robinson speaks at the Green Research Workshop
We made good progress at the Biodiesel Project last week. Greg has made good progress on the electrical side of the plant, and we’re approaching recommissioning with our fingers crossed.
The Project has suffered from being handed from student to student in the past. A new internal wiki will help smooth future hand-offs while standardizing our operating procedures and quality testing. In that vein, quality testing has been helped out by the arrival of a new viscometer, saving us trips to the undergraduate lab.
Last week also contained Green Research Workshop 2012, put on by Risk Management Services, the Sustainability Initiative and Supply Management. The Biodiesel Project came out and made contact with some lovely people. There were interesting and engaging talks about UBC’s new biomass heat and power plant, where UBC’s recycled plastics go, and more over the course of the day.
Particularly inspiring was Professor John Robinson’s keynote. Dr. Robinson is the Executive Director of UBC’s Sustainability Initiative. He spoke about universities’ unique ability to foster sustainable practices both on-campus and as agents of change in the larger community. He outlined UBC’s progress towards its greenhouse gas emissions goals, and noted how transformational it was to think of the entire university budget as a sustainability fund, rather than merely portioning out a fund for feel-good projects. I learned that the new biomass plant and the replacement of the campus steam system with a new hot-water system makes a substantial dent in the greenhouse gas emissions, and I was left inspired and proud to be a student at such a forward-thinking institution.
The big pink and metal thing was our old recovered methanol storage unit. It’s been replaced with the much less-bulky unit that you can see hanging on the side of the plant cage. Now, there’s a lot more room inside the plant cage for us work and perhaps to add a translucent settling and storage tank.
We currently settle and wash the transesterification mixture in the reactor, which we think has a hemispherical bottom. Because we can’t see inside the reactor, we have to guess when the biodiesel has separated from the wash or by-product layer. Similarly, we can’t tell when the wash or by-product layer is out of the reactor until we see biodiesel run out. This takes a lot of time and wastes good biodiesel. A translucent cone-bottom tank for settling will help solve these problems for us, and give us a better place to store our product than in the bunch of buckets we keep it in now.
We’ve been working on the Biodiesel Project for a while, but haven’t said much about it here. No longer! Now you can visit the new Biodiesel Project page for information and updates.
Lots of exciting work has been going on to revamp the legacy reactors and AMS Sustainability has helped out by providing funding to hire two summer students. Standardization of quality testing procedures has begun, and an appropriate fuel dispenser has been found for our future fuelling site in the CHBE yard.
Time & Location: Friday, March 30th, 3:00-4:00 pm in GEOG 100.
A lecture by Kenneth M. Golden discussing how mathematical models of composite materials and statistical physics are being used to study key sea ice processes such as melt pond evolution, snow-ice formation, and nutrient replenishment for algal communities. These processes must be better understood to improve projections of the fate of sea ice, and the response of polar ecosystems. Video from recent Antarctic expeditions where we measured sea ice properties will be shown.
