introduction all tissues have some capability for synthesis of the non-essential amino acids, amino acid remodeling, and conversion of non-amino acid carbon skeletons into amino acids and other derivatives that contain nitrogen however, the liver is the major site of nitrogen metabolism in the body. The diameter of the fractionation or distillation column is a very critical parameter in optimising the plant output the column must be designed to ensure that f-factor and liquid load are maintained within the operating range of packing to ensure efficient operations.
