The invention discloses a method and a process to cost effectively manufacture biodiesel from refined vegetable oil via continuous transesterification by attaching a specially designed low temperature and low pressure waterless continuous biodiesel unit at vegetable oil refinery by Unking pipelines from the refined oil bulk stofage tank (1) directly to the reactor (9), thus eliminating the need to transport the refined oil feedstock, erecting a new storage tank facility, putting-up a new steam boiler and providing a huge land area as in the case of a new plant facility for the commercial production of palm biodiesel. Waste refinery heat is utilized by heat exchanger (7) to minimize the fuel use by thermal oil heater (8) for heating purposes in the specially designed reactors (9), (10), (11), (12), (13), (14), (15), biodiesel purifier (16) and glycerol purifier (17). As the processes of palm diesel separation and purification are continuous and waterless, there is no need for a water treatment plant and big tanks for big production capacity.
