Semi-Continuous Reactors
Continuous Addition of Reactants in Batch Processes
Many industrial processes require strict control of reaction rates by limiting one of the reactants or nutrients. At Foeth, we have a large inventory of used semi-continuous reactors, ideal for these operations. These are equipment from well-known brands in the European market and are in optimal operating condition. All our machines are tested by our experts, and their mechanical integrity, as well as their functionality, is verified before sale and delivery. Visit our facilities in Barneveld, Netherlands, to explore the different types of reactors in our catalog. You can also request information directly from our website. We prepare quotes without obligation and export worldwide.

Semi-Continuous Reactor – Definition and Operation
A semi-continuous reactor is a variation of the batch reactor. Semi-continuity can be established under different circumstances, mainly by mixing continuous elements with intermittent ones. Notable operational scenarios include:
Continuously or intermittently adding a reactant to a batch of product within the reactor.
Removing a product as it is generated, either intermittently or continuously, from the reactor.
A classic example is many biological processes where oxygen and nutrients are continuously added during the reaction. It is also possible to remove gaseous waste products. This mode of reaction allows for strict control of the ongoing reaction, helping to maintain the reaction rate and operational conditions throughout the process duration.
Semi-Continuous Reactor – Applications
Semi-continuous reactors are frequently used in the chemical industry, organic chemistry laboratories, biotechnology industry, and fermentation processes. They are specifically recommended for:
Homogeneous liquid-phase reactions, facilitating conversion control to achieve maximum productivity in the shortest reaction time.
Highly exothermic reactions, such as fermentation, limiting heat removal and allowing better temperature control of the process.
When there is a very low concentration of one of the reactants to ensure its conversion and improve process performance.
Bioreactors and fermenters adjust process conditions for cell growth by continuously adding oxygen and nutrients over time. The semi-continuous reactor has a wide range of applications in the production of penicillin, erythromycin, riboflavin, beta-carotene, and vitamin B12 from microbial fermentation processes.
