A small-capacity multi-purpose batch plant comprises a multi-floor type structure and reaction vessels with jackets for heating and/or cooling. The jacket consists of two halves which are attachable to and detachable from the vessel by closing and opening. The vessels are transported to any position in the structure by stacker cranes and/or conveying trucks in horizontal directions in the same stages and in vertical directions between the different stages. Heating and cooling of the vessels can be done with any heating and cooling media. The usable temperature range is wide, and there is no risk of distortion and cracking at the welded parts of the vessels due to thermal stress. Processes in which transfer of the liquid, particularly, separation of two phases or dropping is involved can be carried out without using pipings and pumps, and thus, contamination is minimized.
