Process and system for producing biodiesel

A method of producing biodiesel using a conduit contactor in fluid communication with a collection vessel, the method comprising:

• introducing a first stream comprising an alcohol proximate a plurality of fibers positioned within the conduit contactor and extending proximate to the collection vessel;
• introducing a second stream comprising an oil into the conduit contactor proximate to the plurality of fibers, wherein the second stream is in contact with the first stream;
• reacting the oil and the alcohol to form a single phase;
• receiving the single phase in the collection vessel;
• and
• separating biodiesel from the single phase;
• wherein separating biodiesel from the single phase comprises:
• (i) introducing a third stream comprising water and an acid proximate a plurality of fibers positioned within a second conduit contactor and extending proximate to one or more collection vessels:
• introducing the single phase into the second conduit contactor proximate to the plurality of fibers;
• and withdrawing separately biodiesel and the third stream from the one or more collection vessels;
• or
• (ii) introducing a third stream comprising water and an acid into the conduit contactor proximate the plurality of fibers;
• introducing the single phase into the conduit contactor proximate the plurality of fibers;
• and withdrawing separately from the conduit contactor the biodiesel and the third stream.
