Know MoreThe Demonstration plots the conversion versus reactor volume for either a CSTR (continuous stirred-tank reactor) or a PFTR (plug flow tubular reactor). The volume (in liters) required to obtain 90 conversion in the reaction is indicated by the green dot in the figure. The reaction takes place in the gas phase with a rate constant . The feed flow rate is and corresponds to a composition such · Reactors are usually designed based on rate considerations. Two commonly used reactors are the CSTR (continuous stirred tank reactor) and the PFR (plug flow reactor). These reactors provide enough residence time for the reaction to take place with satisfactory conversion. In such
