You guys in the south have it soooooooo made!

Things dropped down to 22 deg. F with a windshield of 14 deg. and my 100% bio TDI wouldn't start --- UGH!!! But I've been wanting to know the limit of our standard mixed feedstock biodiesel purified using ion exchange resin - so now I know (below 25 deg. for a prolonged period of time).

Besides that - being able to process outside year round has to be fantastic!!!

Jealously,

Its been in the 40s and 50s at night and cold oil is a pain. I have about stopped production for the past month (along with some other issues leaving me with NO time)
All this bio stuff is fun and cool but I am starting to plan out a SVO setup for my truck. I have a much better understanding of it all now and will probably build my own conversion soon.

I have a problem regarding use of amberlyst BD 20 catalyst for biodisel. Can it be used for a batch process. If yes, can someone please suggest me a way.

Thanks a lot

Deepak

Deepak,

I believe the Amberlyst BD 20 is intended for FFA esterification however it the FFA content is to high and even if its only moderately high it produces enough water to saturate the resin and renders it useless for biodiesel production.

According to the literature you can flush it with methanol and keep going but this seems to be a pain with out somekind of industrial methanol recovery unit...

Lastly, just so everyone knows we will be performing several on the spot demonstrations in booth 445 (Thermax-USA booth) so please come by take a lo0k and say hi!

We will have a miniature lead lag column set up thanks to Chad utilizing a really cool clear head metering pump so everyone can see the biodiesel coming in and going out.

These demonstrations will include pre and post testing.

Some of the test being performed for sure are Soap ppm, Total Acid Number and our New Biodiesel Percent methanol test.

And we need some help because we would also like to do a total Glycerin/glycerides test so if some one has a line on a GC or some other method please please please let us know.

A Demonstration Schedule will be posted later.
