The purpose of this paper is to identify the relations between transportation energy consumption and its impacted factors. We first analyze the current status of transportation energy consumption in China. Then, the logarithmic mean Divisia index (LMDI) technique is used to find the nature of...

This paper analyzes the effect of applying a combined cooling, heating and power (CCHP) system in two types of buildings: residential and office buildings in Dalian, China. The CCHP system configuration was optimized by adding an air-conditioning system (AC) and a heat storage tank (HST) in each...

We have designed a solar thermoelectric cogenerator (STECG), which can supply electric power and heat simultaneously, by adding thermoelectric modules to the heat pipe in evacuated tubular solar collectors. A pilot experiment shows that the STECG can generate 0.19kWh of electrical energy and...

The Pilot-Scale Hydrate Simulator (PHS, 117.8L pressure vessel) is used to study the methane hydrate dissociation with dual horizontal wells using both the steam assisted gravity drainage (SAGD) and the steam assisted anti-gravity drainage (SAAD) methods. This study is the first time to propose...

A 117.8L three-dimensional pressure vessel is used to study the methane hydrate dissociation with the steam assisted gravity drainage (SAGD) method. It is called the Pilot-Scale Hydrate Simulator (PHS). This study proposes the evaluation and the comparisons of the gas production performance by...

The gas production behavior from methane hydrate in the sediment by depressurization was investigated in a novel pilot-scale hydrate simulator (PHS), a three-dimensional pressure vessel of 117.8L. Experimental results are compared with those in a cubic hydrate simulator (CHS) with the effective...

The cubic hydrate simulator (CHS) is used to study the methane hydrate production behaviors in porous media by the thermal stimulation with a five-spot well system. The hot water injection rates range from 10.0 to 40.0ml/min. The thermal stimulation process is analyzed, and the conclusions are...

The Cubic Hydrate Simulator (CHS), a three-dimensional 5.8L cubic pressure vessel, and the Pilot-Scale Hydrate Simulator (PHS), a three-dimensional 117.8L pressure vessel, are used for investigating the production processes of hydrate. The gas production behaviors of methane hydrate in the...

The kinetic behaviors of methane hydrate dissociation under depressurization in porous media are investigated through experimental and numerical simulations. Hydrate samples with low gas saturations (SG⩽0.10) are synthesized in the pilot-scale hydrate simulator (PHS), a novel three-dimensional...

The cubic hydrate simulator (CHS) is used to study the methane hydrate production behaviors in porous media with three different methods, which are the depressurization (DP) using a single well, the heat stimulation using five-spot well (HS-5S), and the heat stimulation in conjunction with...
