Natural gas based, ultra-low carbon ammonia without fluegas scrubbing
Presentation

Reducing the carbon footprint of ammonia is urgent more than ever, and requires new technology innovations to achieve this goal, while keeping these plants competitive and viable. In this session, we will review latest proposed technologies from thyssenkrupp Uhde to achieve ultra-low carbon emissions by implementing a new process flowsheet that replaces the common primary reforming approach and eliminates the need of a fluegas scrubbing system. We will also review the advantages of the new proposed technologies in terms of capex and management of risk associated with new technology implementation.

Making ammonia blue - the easy way
Presentation

Production of low-carbon “blue” ammonia requires the addition of a carbon capture & storage (CCS) solution to the ammonia value chain. With the prevalence of geologic storage immediately below many US ammonia production facilities, onsite co-location of CCS facilities provides a number of attractive benefits to producers looking to make their ammonia low-carbon. Onsite CCS is a proven, ready-to-execute solution (the only two existing CCS projects in the U.S. today are co-located with emitting facilities) that delivers a lower cost, lower complexity decarbonization pathway for ammonia production, while simultaneously capturing the benefits of “outsourcing” CO2 disposal.

Economic analysis for hydrogen - ammonia decarbonization of a natural gas plant - a phased approach
Presentation

This paper summarizes a comprehensive technical and economic analysis of a hydrogen-ammonia upgrade to an existing 42 MW natural gas plant. A phased approach is carefully chosen which deploys low-carbon technology in modules which are palatable by large-scale utility customers. The objective is to minimize capital costs of the conversion while maximizing decarbonization as each phase is deployed. A phased approach delivers optionality to utilities which are often locked into carbon-emitting technologies by protracted investment durations. Phase one details implementation of an on-site thermal pyrolysis system. Existing natural gas infrastructure and plant waste heat are used to provide clean hydrogen.…
