The fifth merger wave in the USA and the parallel fourth merger wave in the UK that occurred in the 1990s was characterised by a large number of acquisitions of firms operating in high technology areas, such as the telecommunications, computers, the Internet, biotechnology, communications etc....

The energy saving mechanism and the potential of efficiency improvement for coal to synthetic/substitute natural gas and power plant with different schemes and CO2 capture is disclosed through exergy analysis, and the effects of key parameters on exergy losses and system performance are...

Polygeneration system for chemical and power co-production has been regarded as one of the promising technologies for fossil fuel sustainable utilization. In this paper, a new polygeneration system with carbon capture is integrated, based on coal gas and coke oven gas inputs for methanol and...

By synthetically combining the utilization of different fuels and the co-production of alternative fuels and power, a multifunctional energy system (MES) can present more opportunities to achieve higher efficiency, lower investment, and less environmental impact as compared to traditional energy...

Reviewing the progress of CO2 capture and storage (CCS) technology, the main obstacles and the potentials of greenhouse gas control in China are identified. An important point can be drawn is that the innovative energy systems, besides simple implementation of existing technology, are needed for...

The industrial waste heat parameters, like flow rate and temperature, usually fluctuate in a certain range due to the variation of upstream industrial process. However, the heat recovery systems are usually designed not under the fluctuation range but under a specific point, therefore, the most...

The distribution of energy and industry in China is extremely uneven. The western region is rich in energy resources but relatively economically backward, while the eastern region, particularly, the southeast coastal area, is an industrially-developed area but is short of energy resources. On...

To develop total energy systems and reveal characteristics of polygeneration systems, we have investigated one coal-based polygeneration system for power and methanol production, and compared it with its original individual processes. The results indicate that the polygeneration system will save...

Polygeneration system for chemical and power co-production has been regarded as one of promising technologies to use fossil fuel more efficiently and cleanly. In this paper the thermodynamic and economic performances of three types of coal-based polygeneration system were investigated and the...
