Thermally self-sufficient process for single-step coproduction of methanol and dimethyl ether by CO₂ hydrogenation

Methanol and DME are highly efficient fuels and relevant building blocks that can be synthesized by CO₂ hydrogenation. While several alternatives for methanol production by CO₂ hydrogenation have already been developed at a commercial scale, DME production is still based on methanol dehydration. In this sense, the...

Thermally self-sufficient process for cleaner production of e-methanol by CO₂ hydrogenation

The hydrogenation of CO₂ to methanol is a technology that converts a greenhouse gas into a valuable chemical compound that efficiently stores energy. Several alternatives to perform this process have been proposed, but they are either not thermally self-sufficient and depend on using external fuel, or the power usage per ton of...

Unraveling the effect of variable natural gas feedstock on an industrial ammonia process

Ammonia plays critical role as the second most produced chemical commodity with around 80% used in producing nitrogen-based fertilizer. Considering the decline of reserves of fossil-based feedstocks it is imperative to shift towards greener alternatives. However, such green ammonia processes are far from being economically viable. This makes...

Process simulation development of a clean waste-to-energy conversion power plant: Thermodynamic and environmental assessment

Waste-to-energy (WTE) conversion technologies for generating renewable energy and solving the environmental problems have an important role in the development of sustainable circular economy. This paper presents a novel high-efficiency WTE power plant using refuse-derived fuel (RDF) as feedstock by integrating torrefaction (T) pretreatment...
