Axial-radial Flow Converter

In conventional shift converter designs, the process gas travels axially through the catalyst bed. In contrast, in axial-radial flow converters, the process gas travels axially and radially through the catalyst bed. This results in increased conversion efficiency and reduced pressure drops through the process. This measure is applicable to all types of feedstocks and to both CO shift converters and ammonia synthesis converters.

Chinese flag Before the renovation at the ammonia plant of Guizhou Chitianhua Group Co., Ltd., the process gas in the shift converter was travelling axially through the catalyst bed. After the renovation, the process gas travels axially and radially through the catalyst bed and the size of the catalyst granules is reduced to 3x5mm. The result was improved conversion efficiency and increased catalyst lifetime (Jigang, 2004)

Assessment to Action (A2A) Toolkit

Developed by IIP, in collaboration with energy expertsat ICF Marbek, members of the IFA and experts in China, the A2A (Assessment to Action) Toolkit is a free suite of resources on energy management and technology best practices created for ammonia companies. The A2A Toolkit provides a first-order, high-level assessment to identify and prioritize energy efficiency opportunities. It does so by drawing on various assessment modules on technical best practices, management best practices (based on ISO 50001 standard) and productivity improvements.
