Abstract

This project was undertaken to design a process for the production of acetic acid from the carbon monoxide content of a steel mill’s off-gas stream and evaluate its reachability. To purify the off-gas stream, the LO-CAT™ process, limestone wet scrubber and COSORB™ process were used. The Acetica™ process was chosen for the carbonylation reaction between CO from the off-gas and purchased methanol. Aspen Plus™ was used to model the process and identify equipment specifications. Important assumptions made in the modelling phase of the project included omitting the catalyst from the COSORB™ process and drastically simplifying the reactor model in the Acetica™ process. A process safety analysis was performed via a HAZOP study and P&ID’s for the plant were developed. From the cost analysis, it was shown that the overall process could be profitable after less than 4 years. However, the extraordinarily large feed stream used necessitated the acceptance of some assumptions in the calculation of the investment- and production costs.
