Comparative analysis of the transportation of select petrochemicals
Large volumes of hazardous cargo move across US roadways daily. Field counts are conducted on sections of roadway that provide aggregated volumes. A high level of interest exists in acquiring the capability to replicate these periodic field counts through a computer–simulated programme. Base data and computer simulation models were identified, which could be coordinated with field counts. The ...

Advances in flashpoint testing: economic impact
Flashpoint testing is one of the oldest methods of the ASTM D02 Committee on Petroleum Products and Lubricants, which was formed in 1904. The most prevalent standards are ASTM D56 (Tag Method), D92 (Cleveland Method), and D93 (Pensky-Martens Method). These classical techniques, commonly referred to as open-cup and closedcup methods, share a common principle: A test flame is lowered into the ...

The empirical analysis for fractal features and long-run memory mechanism in petroleum pricing systems
The fractal behaviour for petroleum pricing is investigated in several international systems. Based on the time series of Brent & WTI crude oil and Rotterdam & Singapore Leaded gasoline prices (daily spot), this paper analyses the fractal features in the systems under study by using Rescaled Range analysis (R/S analysis). This paper also estimates the Hurst exponents; thus, long-term memory ...

Fiscal system analysis – contractual systems
Production sharing contracts are one of the most popular forms of contractual system used in petroleum agreements around the world, but the manner in which the fiscal terms and contract parameters impact system measures is complicated and not well understood. The purpose of this paper is to quantify the influence of private and market uncertainty in contractual fiscal systems. A meta-modelling ...

Thermophysical characteristics of the biomass tar from a crop stalk gasification system
Presently, the biomass gasification and centralised gas-supply system fed by crop stalks is still at the stage of development and research in China. The purifier of the system has some problems such as huge device, low purifying efficiency, and poor disposal of tar causing secondary pollution. For this reason, the distillate range, calorific value, ignition temperature, flash point and viscosity ...
