Should I use sodium hydroxide or potassium hydroxide when using your Circle Biodiesel Processor?
It depends upon pricing, quality of glycerine output desired and production controls. This is more a discussion based on what your finished output is that you desire. Please give us a call and we can help you determine the best choice based on your specific needs.
Should I use pre-mixed methylates (either sodium or potassium)?
It is best to use pre-mixed methylates if you are going to be doing very similar production runs (using the same feedstock all the time). If you are using multiple feedstocks for biodiesel production, you should look into mixing your own methylate mixture (according to your titrations) or supplementing the pre-mixed methylate with your own mixture.
How can I add more sodium hydroxide or potassium hydroxide if I need to slightly adjust for free fatty acid content?
You can mix it in a drum barrel and then pump the mixture into our methylate mixer which is on the ‘Circle Biodiesel Processor’.
