Abstract

Abstract: The objective is to design a plant from raw material to product for the production of aniline by direct amination of benzene. The process design is started on a conceptual level and ended on a basic engineering level as well as a techno‐economical evaluation. The amination of benzene by hydroxylamine was used as basis. For the production of hydroxylamine four routes are proposed. The most promising route is the chemical reduction of nitric oxide with hydrogen. The process evaluation shows that 27 % of the atomic nitrogen is lost. The atomic carbon efficiency is close to unity. Furthermore, a significant amount of steam can be produced. From an economical perspective, there is still room for improvement because the return of investment is quite low and the payback period is quite high. Abstract : Aniline is a frequently used bulk chemical. Since today's synthetic routes suffer from low atomic efficiencies, a systematic approach was used to develop a process to produce aniline from benzene by direct amination. The proposed process can deliver a significant amount of high‐quality steam and is economically and technically feasible.
