Natural gas liquefaction allows to transport this energy vector over long distances from stranded reserves to the market. Pure Refrigerant Cascade processes will be responsible for more than 105 mtpa of the LNG base-load production by 2021. Classical…
Remotely located oil fields with high gas-oil ratio and high carbon dioxide content impose challenges for efficient and sustainable gas processing and monetization. This work investigates gas-to-wire coupled to carbon dioxide enhanced oil recovery as…
Supercritical water gasification (SCWG) is a promising technology for oil-containing wastewater treatment. In this work, a non-stoichiometric two-phase (i.e., supercritical and solid phases) model is established for the thermodynamic analysis of SCWG…
To achieve a 100% renewable energy system, plants integrating the electricity, heating and transport sectors in a Smart Energy System are required. In this work, three different polygeneration plants producing biofuels and heat, while interacting…
The nitric acid pressure leaching (the NAPL) process has caught people’s attention owing to the increasing demand for nickel and cobalt, and the gradual depletion of nickel sulfide. In this process, iron, aluminum, nickel, and cobalt are separated…
Daily fluctuations in natural gas and electricity load profiles call for an urgent need for adequate storage infrastructure. However, building isolated electricity and gas storage systems suffers from low efficiency and high investment. In this…
Natural gas peak shaving power station with gas-steam combined cycle is widely used to meet the demand of peak load regulation of the power grid. However, the exhaust heat of the system and the high-grade cold energy from the nearby liquified natural…
This paper proposed a cryogenic power generation system composed of Rankine cycles and direct expansion cycle, aiming at the efficient utilization of flue gas waste heat and liquefied natural gas (LNG) cold energy. Both the sensible heat and latent…

A novel dual-pressure Allam cycle integrated with the cold energy recovery of liquefied natural gas is proposed and analyzed in this paper. The feature of this system is that the cold energy of liquefied natural gas is successively utilized in two…
The goal of this work is to solve the problem of low thermal efficiency of stoichiometric natural gas engines by combining the Miller cycle with a high geometric compression ratio (GCR). A one-dimensional thermodynamic model of a stoichiometric…
Renewable electricity has been developed very fast to reduce both the reliance on fossil energy and CO2 emission, and its utilization for the sustainable production of chemical products is of increasingly interest. In this work, opportunities for…
Worldwide concerns for fuel shortage and environmental problems call for efficient exergy recovery of industrial processes, especially in energy-intensive industries like natural gas supply chain. Pressure reduction station is a key infrastructure…
