The Revamping of CF Industries #5 NH_3 Plant: Application of Casale’s Isothermal Technology and Clariant’s AmoMax®-10 Catalyst

摘要

The CF Industries (CFI) Ammonia Plant No. 5 in Donaldsonville, LA has been in operation for morernthan 35 years. The plant’s design capacity was 1150 STPD. To improve the ammonia converterrnperformance CFI opted for revamping both the main and the booster Ammonia converters. The mainrnconverter was upgraded from a Casale 4 bed with interchanger and 122-C exchanger to anrnIsothermal converter. The second converter which had not been in service was converted to a singlernbed adiabatic converter. Both converters now combine Casale’s internals with Clariant’s wustitebasedrncatalyst AmoMax®-10. CFI led the project with the goal of achieving a higher converter exitrnammonia capacity with improved energy savings. The combined effect of CFI project managementrnand advanced technology from Casale and Clariant resulted in a successful project. The project wasrninitiated in 2010 and a successful test run certificate was signed by the parties in September 2013.rnThis discussion illustrates the teamwork between CFI, Casale, and Clariant to implement this projectrnalong with outlining the improved converter and synloop performance and production efficienciesrnachieved after the project was completed.
