Semibatch reactor
open-in-new
<p>For both <a href="/facts/Chemical_engineering/Fb64amQf">chemical</a> and <a href="/facts/Biological_engineering/N8WPz0P7">biological engineering</a>, Semibatch (semiflow) reactors operate much like <a href="/facts/Batch_reactor/dbdTuVtf">batch reactors</a> in that they take place in a single stirred tank with similar equipment. However, they are modified to allow <a href="/facts/Reactant/c3GLInCu">reactant</a> addition and/or product removal in time. </p><p>A normal batch reactor is filled with reactants in a single stirred tank at time t = 0 {\displaystyle t=0} and the reaction proceeds. A semi batch reactor, however, allows partial filling of reactants with the flexibility of adding more as time progresses. Stirring in both types is very efficient, which allows batch and semi batch reactors to assume a uniform composition and temperature throughout. </p>
