Techno-economic assessment of the FReSMe technology for CO2 emissions mitigation and methanol production from steel plants

The iron and steel industry accounts for 6 % of the global CO2 emissions and it is one of the main hard-to-abate sectors that must be un-locked to reach climate neutrality in the coming decades. The objective of this work is to assess the economics of the FReSMe (From Residual Steel gases to Methanol) process for reducing the carbon footprint of...

Cost projections for microwave plasma CO production using renewable energy

Successful deployment of renewable fuel production requires substantial cost reduction along the entire value chain of the underlying manufacturing routes. To improve their performance, renewable fuel pro duction technologies should follow a cost-reducing learning curve. In this article, we adopt recent evi dence that learning-by-doing is...

Reactive Water Sorbents for the Sorption‑Enhanced Reverse Water–Gas Shift

Sorption-enhanced reverse water–gas shift (SE-RWGS, here designated as ‘COMAX’) was studied with bifunctional reactive sorbents. First proof-of-concept is presented of the successful design of a multifunctional reactive sorbent, which combines CO2 activation and water adsorption functionalities in an integrated reactive sorbent, i.e. the active...

Sorption enhanced dimethyl ether synthesis for high efficiency carbon conversion: Modelling and cycle design

Dimethyl ether is one of the most promising alternative fuels under consideration worldwide. Both the conventional indirect DME synthesis and the improved direct DME synthesis process are constrained by thermodynamics, which results in limited product yield, extensive separations and large recycle streams. Sorption enhanced DME synthesis is a...

Steam separation enhanced reactions: Review and outlook

Enhancement by steam separation is a promising process intensification for many types of reactions in which water is formed as a byproduct. For this, two main technologies are reactive vapor permeation (membrane technology) and reactive adsorption. Both can achieve significant conversion enhancement of equilibrium limited reactions by in situ...

Integrated system for capturing CO2 as feedstock for algae production: 13th International Conference on Greenhouse Gas Control Technologies, GHGT 2016, 14-18 November 2016, Lausanne, Switzerland

In view of its promise as sustainable process for CO2 capture and its potential in the production of feed, food and natural high value products such as omega-3 fatty acids and anti-oxidants such as astaxanthin, large scale algae cultivation is gaining commercial interest. Currently, most systems are based on directly contacting CO2 containing...

New methodologies for integrating algae with CO2 capture

It is generally recognized, that algae could be an interesting option for reducing CO2 emissions. Based on light and CO2, algae can be used for the production various economically interesting products. Current algae cultivation techniques, however, still present a number of limitations. Efficient feeding of CO2, especially on a large scale, is...
