DEPARTMENT OF CHEMICAL ENGINEERING Reaction Engineering CGC035 / CGC052 Problem Sheet 3 - Fluid-fluid reactions 1. The reaction rate for the heterogeneous reaction A(g) + B(l)→ products is second order according to the expression -rA=kCACB and it is relatively slow compared to mass transfer so it takes place in the bulk of the liquid. Combine the following rate expressions for diffusion through the gas and liquid films‚ -rA=kAga(pA-pAi) and -rA=kAlaCAi-CA‚ with Henry’s law pAi=HACAi

The end result is‚ therefore reliable in terms of engineering and operational expectations‚ but it is not quantitative and may not consider the consequences of complex sequences of human errors. The objectives of a HAZOP study can

MATLAB BASED AUTOMATED CONTROL SIMULATIONS IN BIO-REACTORS ABSTRACT Designing of bioreactors is a very complex process and requires the clear understanding of the biological phenomena occurring during the process and the development of best suitable reactor for bringing out the product in an economically viable‚ large scale form. The conventional techniques currently in uses are very time consuming and some of their steps may even be based on trial and error format. Therefore there

Process” by Phil Leckner it points out two incidents one in Dalton‚ Ga and one in Texas City‚ Tex where poor guidelines and poor process designs caused explosions and leaks that injured and killed workers on site. When working on a commercial scale chemical reaction it is essential to promote safe process design so incidents can be avoided. The two flow diagrams that are talked about in the article are block flow diagram (BFD) and the process flow diagram (PFD). BFD’s show he overall picture of

Its main use is as a chemical intermediate in the manufacture of acetone cyanohydrin for methyl methacrylate‚ bisphenol A and aldol chemicals. Catalytic dehydrogenation of propanol can be chosen as an alternative synthetic route when high-purity of acetone is required‚ such as in biomedical applications. A single pass conversion of
