thyssenkrupp Uhde Completes Hydrogen Recovery Unit at Fertiglobe UAE Plant

29 September 2025

Key highlights

The hydrogen recovery unit increases ammonia production by 6% and reduces CO2 emissions.
The plant has a capacity of 2,120 metric tons of ammonia per day.
The project delivers an annual IRR on investment of over 25%.
The unit was installed while the plant was in full operation.

Project Overview

thyssenkrupp Uhde has completed the start-up of a hydrogen recovery unit (HRU) at Fertiglobe's Fertil plant in Ruwais, UAE. The project involved engineering, procurement, and site supervision during installation and start-up.

Ammonia Production and Efficiency

Post-revamp, the plant now operates with a capacity of 2,120 metric tons of ammonia per day. The HRU enhances hydrogen recovery from ammonia synthesis purge gas, increasing feedstock utilization and boosting ammonia output by 6%.

Environmental Impact

This project marks a significant step towards sustainable ammonia production, reducing carbon dioxide emissions per ton of ammonia produced. The HRU and an extended ammonia recovery unit were installed without interrupting ongoing operations.

Financial and Operational Benefits

The project delivers an annual internal rate of return (IRR) on investment of over 25%, aligning with Fertiglobe's Manufacturing Improvement Plan focused on production and energy efficiency.
