A runtime programable RS decoder that can operate on multiple pieces of data during one clock cycle in order to generate, reduce, and evaluate polynomials involved in the decoding of an RS code, and which allows a user to choose the RS code after the circuit has been implemented. According to one such implementation, a radiofrequency amplifier circuit is implemented in a SMD package. Workpieces of a batch are loaded onto all of the treatment sites and then simultaneously and identically treated by operation of treatment stations with which the process sites are aligned. 2 to 4 h\u22121, producing a gas phase, an organic liquid phase and an aqueous liquid phase, anda stage of separating said gas phase, said organic liquid phase and said aqueous liquid phase at a pressure close to the reaction pressure.
