Ammonia production using hydrogen (H2)-rich offgases is an established method, but it is practiced only in a handful of plants. The dynamics of new feedstocks in the petrochemicals industry coupled with several new process options can provide opportunities to utilize larger volumes of H2-rich offgas streams to produce low-cost ammonia (NH3). These resources are large enough to integrate and support a typical worldscale NH3 plant and provide an economy of scale even in smaller sizes with an added environmental benefit. However, sourcing those offgas streams poses obstacles. Examples of NH3 units located on the US Gulf Coast (USGC) and in the Middle East (ME) demonstrate possibilities. Feedst
