Abstract

A method is proposed of correcting the design of countercurrent sepn. columns for the impact of axial-dispersion effects. After computing the required no. of transfer units (NTU) employing conventional procedures based on the plug-flow assumption, the method permits the estn. of a correction factor accounting for deviations from plug flow. This factor is used to correct the NTU for such effects. The procedure also works in correcting height-of-transfer-unit data that are affected by axial dispersion. The method is straightforward and simple to use, and the results agree in simple cases within a few percent with those obtained from a rigorous soln. of the model of axial dispersion.

Plug flow reactor model

The plug flow reactor model (PFR, sometimes called continuous tubular reactor, CTR, or piston flow reactors) is a model used to describe chemical reactions in continuous, flowing systems of cylindrical geometry. The PFR model is used to predict the behavior of chemical reactors of such design, so that key reactor variables, such as the dimensions of the reactor, can be estimated.

Continuous stirred-tank reactor

The continuous stirred-tank reactor (CSTR), also known as vat- or backmix reactor, mixed flow reactor (MFR), or a continuous-flow stirred-tank reactor (CFSTR), is a common model for a chemical reactor in chemical engineering and environmental engineering. A CSTR often refers to a model used to estimate the key unit operation variables when using a continuous agitated-tank reactor to reach a specified output. The mathematical model works for all fluids: liquids, gases, and slurries.

Chemical reactor

A chemical reactor is an enclosed volume in which a chemical reaction takes place. In chemical engineering, it is generally understood to be a process vessel used to carry out a chemical reaction, which is one of the classic unit operations in chemical process analysis. The design of a chemical reactor deals with multiple aspects of chemical engineering. Chemical engineers design reactors to maximize net present value for the given reaction.
