In this article the prospect of emerging co-production and polygeneration schemes based on pre-combustion decarbonisation and options for geological storage of the CO2 are discussed in a European and Chinese setting. Reference is made to European and Chinese undertakings - especially the COACH...

Power plant on-line measured operational data are often corrupted with random and gross errors. The data reconciliation method can reduce the impact of random errors by adjusting redundant measurements to satisfy system constraints and detect gross errors together with a statistical test method....

A large number of heat flows at various temperature and pressure levels exist in a polygeneration plant which co-produces electricity and chemical products. Integration of these external heat flows in a heat recovery steam generator (HRSG) has great potential to further enhance energy efficiency...

A distributed energy system is a multi-input and multi-output energy system with substantial energy, economic and environmental benefits. The optimal design of such a complex system under energy demand and supply uncertainty poses significant challenges in terms of both modelling and...

In this paper, we present a process-based model to estimate the well-to-tank (WTT) costs of vehicle fuels (gasoline and diesel). The model breaks down the WTT process into four stages, i.e., crude oil sourcing (import and extraction), crude oil transportation, crude oil refining, and vehicle...

In this study, we first define the energy consumption of domestic investment as the investment-driven energy consumption (IDEC). Then, we build an energy input–output model to identify quantitatively the amounts of China’s IDEC from 1992 to 2007. We also use the model to analyze the sector...

The overall exergy losses of co-production systems were decomposed into five sub-systems: chemical reaction processes, heat exchange processes, external exergy losses, turbine/mechanical exergy losses and others. By defining new parameters called energy-saving factors, we quantitatively describe...

Demand for electricity in China kept accelerating in recent years; moreover, there exist serious mismatches among the distribution of power demand, energy resources, and power generation infrastructure across different regions in China, both of which indicate a necessity of a holistic and...
