bio diesel ????s

its getting to be summertime and the price of diesel is going up


a buddy of mine was making biodiesel using an extreme biodiesel 100gal. set up for the past 2or 3 years but doesnt have time anymore. so he wants to sell the equipment to me. whats a fair price for this setup in used condition? would it even be worth it for me to buy it or just build my own setup? ive seen how it works so i know i could make the fuel myself and i have a place thats willing to give me 55gal of wvo each week.

also am i going to see any performance loss/gain running this bio, with upgrades like exhaust chips etc. my buddy said he noticed a smoother idle and french fry smell but thats it.

i know i will need to change fuel filters more often since the bio will clean out the tank and lines, but anything else i would need to do.

I dont know a lot about bio, however, I do know a little about VO.

A couple things to ask yourself
1) Do I have the space to set the operation up? Keep in mind the proceessor, feedstock storage, methanol, finished bio.

2) Do you have the reliable quality sources of feedstock?

3) Do you have the time to collect and process?

4) Do you have more than one biesel vehicle?

Before you pull the trigger on Bio, read up on "dry wash" for cleaning Bio.

When I was running Bio I felt a little less power when I was pulling my boat running >75%. It was not much less but you could tell. I cut back to about b50 and could not feel it anymore. I usually ran about 50% because I could not make it fast enough to run more then that.

Like veggin said, DRY WASH!! I used purolite and my buddy uses eco-pure. so much better then water washing.

Bio is a process that you will have to work out. It takes some time to get in the grove but once you do its not hard. I just dont have the time to baby sit it.

1. i have 5 acres so i would just build a shed to put the processor in.

2. i have a restaurant that is willing to give me 55gal a week

3. right now i have fri-sun off so yea ive got time

4. right now it will only be me running it until i get a couple friends in on it too

i will have to check out dry washing because my buddy always water washed it and thats what takes the time having to drain off the water ever hour or so

right now i was thinking i would just work my way up to a B80 mix.

also how long can the bio be stored after processing it? and what temp would be too low to run a minimal amount of bio like B20?

The quality of Bio will dictate how well it cold flows.

With stabilizers added to ASTM standard bio, I am told 5 months. It should be kept cool and out of the sun also.

Sounds like you got your ducks in a row! Good luck with the project!

This all depends on the Bio and the source oil. Every batch you pick up will be different even if from the same friers! I had some bio that would gel at 50 ish and some that would not gel in the freezer. Every batch is different.

If its above 60 its pretty safe to run b100
b50 should be pretty safe in the 50s
b20 should be ok to freezing.

These are pretty safe numbers and ofcourse your results will verry, test and run at your own risk!
