Dear Nathan, Steven, Crispin,AD et al., Thanks for all your inputs on t caustic add no add issue: I will keep it simple then--the standard low heat /filter, then 80c heat with radiato line heat exchanger starting on petro diesel then switching to veggie oil ad reverse for shutdown …no NaOH: Be in touch end next week with findings. from Lushoto.
