Automated medium–pressure modular liquid–gas reactor

This paper describes an automated reactor in which reactions can be carried out using at least one gaseous reagent and one liquid reagent at a pressure ofup to 5 bar. The reactor was used to produce a hydrogenation reaction, in which system all operations, i.e. introduction of liquids and gases, control and regulation of pressure, temperature and volume of gases introduced and finally draining ofthe reactor, were to be automated. The system is conceived in modular form, each module being responsible for one specific task [1,2].
