Hi guys, i need a little help here. I made a batch wi th my BP 190 the end of november. I got cancer surgery dec 5th so I have not done any brewing since then. Here what happend. I made a batch, it titrated fine, don't remember, but under 5%. Got glycerine out, still had some oil in 24/7 test. Did a re-react as per the manual, got no more glycerine. washed twice. got a loss of oil more than normal. if this batch is finish i have 45 gallons of fuel, approximitly. 24/7 then showed some oil on bottom, looked like good fuel on top, and thena slight layer of oil on top. Never had this result before.

My observations, maybe my titration solution is out of date, giving me a false FFa. other than that I'm lost. the 190 has been sitting for more than a month and I need to get back brewing.

Thanks guys

update,

i just looked at the 24/7 vial that's been sitting in the house for the last month. The original oil layer that was on top has settled out. The fuel left looks real clean. I have a oil level on the bottom with another small level of something. Maybe soap,not sure. I am going to take a new sample from the top of ths bio pro and do a 24/7 on it. If it looks good I will drain the layers on the bottom out andget back to precessing.

any thoughts???

The test you are referring to as 24/7, do you mean 3/27? It should be done at 68f +/- 2, IMO.

If so, your fuel should never fail that test if you have done a second reaction to it.

Do you control the temp. of the test? Cold temps will give a false fail.

Also, do you test your oil for water? Water content in oil is probably the leading cause of bad reactions. It is not the only cause to be sure, but very common. For whatever reason, the BP seem to be more sensitive to water content than other systems. Perhaps it us the routine use of acid base?

HTH.
