Abstract:
By-products of biomass steam gasification are tar and water in the product gas. They can be removed by a cold biodiesel scrubber. Re-using the water phase for steam generation avoids wastewater, but a clean and oilfree condensate phase is required for correct operation of the steam generator. Hence occasionally occurring biodiesel-in-water emulsions in the condensate phase must not be fed to the steam generator. This work shows the effect of packings on the separation of biodiesel and condensate in a bench-scale apparatus. The experiments examined the effect of PP Pall rings, stainless steel Sulzer Mellapak 250.X as well as stainless steel wool and glass wool on biodiesel emulsions derived from rapeseed oil and palm oil. In all cases except for glass wool, packings improved the emulsion separation.
