From left to right :
- Oil drum = Feedstock Holding Tank (FHT)
- 20-litre drum = Filter Unit with vacuum pump below.
- Mixing pumps, condenser behind, liquid trap below
- 45 kilogram propane bottle = Reactor
- Oil drum = biodiesel bubble wash and dry holding tank, switch gear above.
- 20-litre drum = Methoxide Mixer
"I've used the system once a month since last June and had no problems. But the drums are beginning to rust heavily, especially on the methoxide side of things.
"I had my Land Rover emissions test done last year, on standard diesel and the 100% biodiesel.
"The average reading for standard was 1.22 (whatever scale they use). Biodiesel was 0.62!!!
"The bloke doing the check couldn't believe it. They usually sell an expensive additive for people with smoky diesels or if they're just over the MOT emission limit."

I use three of these for bubble washing. They are pneumatic exhaust silencers. They don't rot, they're cheap and they work very well. "Top Hat" inspection hatch and Sulphuric Acid funnel (if using Aleks's Foolproof method) Inside the FHT showing pickup filter and a bit of the immersion heater
