Dynamic Simulation of Green Ammonia Synthesis Plant

The carbon emissions from human activities are causing significant harm to the planet, leading to increased temperatures, melting of polar ice caps, rising sea levels, and other negative impacts on the environment. One promising solution is the use of green hydrogen as a fuel source, which could have a much lower carbon footprint than...

From Bio-Oil to Gasoline: a Novel Integrated Process for Sustainable Fuel Production: A techno-economic assessment of a Power and Biomass to Liquid plant, integrating electrolysis, bio-oil gasification, direct DME synthesis, and DME to gasoline

The intensification of human and industrial activities since the Industrial Revolution has led to a significant increase in global greenhouse gas emissions, posing a threat to life on our planet. As the transportation sector contributes to 23% of global CO2 emissions, it is imperative to reduce its carbon footprint. Developing a worldwide...

Techno-Economic Analysis of An Integrated Direct Air Capture and Mineralization System: A Feasibility Study

Carbon sequestration involves the conversion of carbon dioxide gas into carbonates through reactions with magnesium or calcium bearing minerals, presenting a potential method to mitigate CO2 emissions and reduce their release into the atmosphere. This process can be classified into two categories: in-situ (subsurface) and ex-situ (surface). CO2...

Developing and Controlling a Hybrid Renewable Energy System with Solar PV and Modular Alkaline Electrolysis: The Future of Decentralized Hybrid Renewable Energy Systems

Renewable energy resources like wind and solar have the potential to revolutionize our energy infrastructure and enable a decarbonized society. The intermittent nature of renewables poses a challenge to ensuring a consistent and reliable electricity supply.

Dynamic behavior of a flexible small­scale ammonia synthesis process

Due to climate change, the growth in renewable energy is still accelerating and reaching new records each year. Not everything can be electrified, hence, the production of green hydrogen as an energy vector is gaining momentum. However, lowest cost hydrogen will not always be produced at the demand centres, necessitating transport of hydrogen...

Front-End Techno-Economic and Environmental Analysis on CCU Technologies: Identifying the most business critical pathways for valorization and utilization of carbon dioxide

Carbon capture and utilization (CCU) is an emerging technology for reducing the CO2 concentration in the atmosphere and to limit the negative effects on the global warming. Different from carbon capture and storage (CCS), in CCU the carbon captured from point sources or direct from air is processed to valuable carbon containing products. Several...

Dynamic Modelling of A Rolling Piston Compressor Including A Packed-Bed Drying System

To produce an alternative fuel like Methanol from scratch, on a miniature scale- the reactants CO2 and H2O are sourced locally. Zero Emission Fuels B.V. (ZEF) does this by collecting carbon dioxide from the air, via carbon capture techniques and compressing it to high pressure of 55bars. As a consequence of humidity inside the captured CO2,...

Process System Modeling of Large-Scale Energy Storage, CO2 and Biomass Based Formic Acid Production Systems

Transition to renewable and alternative energy sources has become one of the most important subject of the decade. In The Netherlands today, 11.1% of the primary energy demand is obtained from renewable energy and the biomass accounts for 54% [1]. Another promising material for value added chemical synthesis is carbon dioxide. By utilization of...

Meeting the ever-increasing energy demands in our planet where conventional sources of energy are finite and fast depleting, controlling adverse phenomena like climate change, soil erosion, greenhouse gas emission, ozone layer thinning and pollution will remain profound challenges until widespread adoption of sustainable sources of energy is...

Novel Technology for Hydrogen Separation from Natural Gas using Pressure Swing Adsorption

Australia has a high potential for production of renewable energy, such as wind and solar. Due to the stochastic operating conditions, excessively produced energy can be used to produce hydrogen by electrolysis to store the energy, known as power-to-gas. This hydrogen can be injected into the existing natural gas pipeline network, providing both...

Syngas Purification: Design of a Rectisol® based purification plant for the removal of impurities and simultaneous capture of CO₂ from the works arising gases of an integrated steel mill

The steel making industry is highly energy intensive and a great contributor of greenhouse gas (GHG) emissions. It generated between 7% and 9% of direct emissions from the global use of fossil fuels in 2017 [1]. Gas emissions in an integrated steel mill (ISM) arise mainly from three streams: coke oven gas (COG), blast furnace gas (BFG) and basic...
