A new model used to design the shape and dimension of salt cavern gas storage is proposed in the paper. In the new model, the cavern is divided into two parts, namely the lower and upper structures, to design. The concepts of slope instability and pressure arch are introduced into the shape...

The systematic, transparent and accurate on-line energy information of the production process is quite the basis of mill energy management and conservation. An Energy Management System (EMS) was built according to the characteristics of the energy usage in a typical newsprint paper mill. The EMS...

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 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...

This paper develops a practical miniature and portable vapor compression refrigerator. The dimensions of the refrigerator are 190mm×190mm×100mm and its weight is 2.75kg. It integrates a miniature variable speed rotary compressor with a miniature electronic expansion valve (EXV) operating in...

In this paper, a common rail diesel research engine was converted to operate in dual-fuel mode and extensive experiments were conducted to investigate the effects of natural gas injection timing on the combustion and emissions performance under different pilot injection pressure and timing at...
