ABSTRACT

This paper will highlight some of the critical paths and decision networks involved in the successful development and scale-up of a novel ammonia synthesis catalyst system. The Kellogg Advanced Ammonia Process (KAAP) is based on this new catalyst and represents the first major change in ammonia synthesis catalyst technology since the

magnetite catalyst-based ammonia rocess was encompassed both catalyst development and its subsequent process implementation. The catalyst development required the complete development/scale-up of a proprietary catalyst support manufacturin process and scale-up of

                     The successful process implementation required investigation of catalyst operating conditions and reactor designs to most effectively utilize the unique characteristics of the new catalyst.

Criteria for the desi n of a 3 MTPD Process Demonstration Unit QPDU) are also discussed. This PDU verified the bench/pilot-scale derived kinetic model over a range of conditions using

            as pan ot tne scale-up of catalyst support manufacturing technology and catalyst production scale-up.

The upcoming KAAP retrofit will represent the commercial implementation of the KAAP scale-up of a technology resulting from a twelve-year joint development program between British Petroleum Ltd. and The M.W. Kellogg Co. This paper will discuss the importance of assembling a joint oversight committee to monitor, review and recommend to the management of both companies a consensus course of action during the critical developmenVscale-up phases of the project to meet the overall program goals.
