Manned-spaceship and orbiting stations require light and reliable life-support systems as the crew is subjected to long space periods. Spaceship conditions are regulated by the Environment Control and Life-Support System. Maintaining a breathable and comfortable atmosphere in the spaceship is a critical function of life-support systems. Breathabili...

Expansion-based liquefaction technologies are prime candidates for small scale offshore natural gas liquefaction, aiding in reducing NG chain logistical costs, due to their compactness. This study assesses the sustainability and profitability of three expansion-based small-capacity natural gas liquefaction technologies: the rigid-geometry supersoni...

Under certain conditions supersonic separators promote superior natural gas conditioning over traditional routes. An instigating possibility consists in using supersonic separators to obtain liquefied natural gas that exhibits global growth. This work analyses natural gas liquefaction through a low-scale process using realistic non-isentropic super...

In offshore oil-and-gas fields with high CO2 content, oil-and-gas processing entails recycling CO2 to the field for enhanced oil recovery. Despite blocking fossil CO2 ingress into the biosphere and improving oil production, this entails increasing %CO2 in oil-and-gas with time, challenging the processing plant. Supersonic separator is a compact gas...

Gas-To-Wire is a solution for remote offshore oil-gas fields with high gas-oil ratio and high carbon dioxide content, as it requires minimum natural gas upgrade and is feasible for long-distance transportation. Additionally, combining offshore Gas-To-Wire with carbon capture enables abatement of emissions while providing revenues from enhanced oil...

The possibility of using renewable feedstocks for biodiesel production and reducing gas emissions makes it an attractive large-scale substitute to traditional fossil diesel. Although renewability is one of the main driving forces in biodiesel use, traditional production routes employ methanol as the transesterification agent, a chemical generated f...

The use of renewable feedstocks for biodiesel production makes it an attractive large-scale alternative to fossil diesel. Nevertheless, traditional routes employ methanol as transesterification agent, a fossil based chemical. To improve renewability, governmental policies and subsidies have arisen to promote substitution of methanol. In the Brazili...
