Abstract: Disclosed are a device and method for preparing fatty acid derivatives and more specifically, a device for preparing fatty acid derivatives including three reactors and a method for effectively preparing fatty acid derivatives. The device for preparing fatty acid derivatives including three reactors enables a stable supply of reactants even if a problem occurs in one reactor, and enables continuous and stable operation because delays in the treatment and purification process do not occur. As a result, the device has effects of increasing productivity and reducing production costs. In other words, by operating three reactors instead of two reactors, it is possible to build a production facility that can be operated continuously without stopping, resulting in increased production and reduced production costs. The reactors are operated at a time interval so that only one ammonia feeder and one ammonia collector may be used for all three reactors.
