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...

A new kind of natural gas-based polygeneration system for methanol and power production is proposed in this paper. With the sequential connection between chemical production and power generation, the new system adopts innovative integration of partial-reforming and partial-recycle scheme in...

The thermodynamic analysis and the coupling and optimization between chemical synthesis and power generation in a polygeneration system are presented. Unlike full conversion of syngas into chemicals in the traditional SNG (synthetic natural gas) production system, by moderate conversion the...

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...

The coal based polygeneration with CO2 capture (PG + CC) technology is expected as one of the possible options to mitigate CO2 emissions with low cost and low energy. This work assesses the cost reduction potential of PG + CC technology based on learning curve method, and finds out what...
