I have made biodiesel but have some questions

Beef Tallow and Hydrogenated Oils in the BioPro™

Some of our users have had questions regarding the use of highly saturated fats, hydrogenated oils, and tallows in the BioPro™ biodiesel processors. To make a long story short, they can be processed in a very similar manner to any other fat or oil, with a few minor differences.

What to do with your glycerin layer

What is the glycerin layer (aka "glycerin")?

Methanol Vapor Information Applicable to the BioPro™ 190

Assuming that the BioPro™ is loaded cold (there has been no preheating of the oil), during the 8 hour reaction processes, due to thermal expansion of the gas in the vacant space above the fluid in the BioPro™, as well as the partial pressure exerted by methanol as it dissolves in free air inside the vessel, there is typically some venting that occurs. Worst case, as much as 1 cubic foot of methanol gas may be vented during this eight hour period. (In reality, this is probably closer to 0.50 cubic feet. The effects of the methanol under partial pressure cause the bulk of the initial venting to be composed almost entirely of just air.) But we’ll stick with 1 cubic foot for worst case.

High Quality Biodiesel and Engine Life

To a large extent, the longevity of diesel engines is a result of the lubricity of
diesel fuel.

Why ASTM is important and why the BioPro™ was designed to meet its requirements.

ASTM International (ASTM), originally known as the American Society for Testing and Materials, is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services. ASTM D6751 Is the name given to the entire suite of tests performed on biodiesel fuel. For a batch of biodiesel fuel to meets or exceed ASTM D6571, it must, by definition, meet or exceed the various specifications that comprise D6751.

Five Tips for Storing and Retrieving Your BioPro

Meet The Challenge of Cold Weather Biodiesel Washing

Washing biodiesel in cold weather can be tricky!

Just ask the thousands of small scale producers across the U.S. who view wintertime as the "off season" of biodiesel production, largely due to the fuel washing difficulties that the cold weather brings with it.

Although these issues can affect the BioPro™ line of biodiesel processor's, it is still possible to successfully wash batches, if the user is aware of the difficulties that can arise and takes some simple steps to deal with them.

Before delving into how to deal with the problems, it's important to understand what these problems are.

How to Prepare Your Feedstock

The BioPro 190 will not process oil of mineral origin such as motor oil

The BioPro™ 190 is designed to process feedstock of vegetable or animal origin. This would include crude de-gummed oil, vegetable oils, tallow, lard, yellow grease, or any mixture of the above. These are collectively known as “feedstock”. Often animal feedstock is found in solid form, even at room temperature (think of leftover bacon grease in your frying pan.) Since the BioPro™ 190 can only process liquid feedstock, any solid tallow must be melted prior to processing.
