Field-pipelines leakage detection based on the negative pressure wave theory is mainly aiming to effectively process pressure sample signal in time domain. Previous methods often perform well for detecting large leakage but poorly for small leakage.…
The control and managing of pipelines have been assuming a major importance for all kinds of fluids to be conveyed through. When the fluid is like oil, harmful liquid and/or water for human beings necessity, the monitoring of pipelines becomes…
Since the pressure fluctuation signals are masked by noise and can not be detected, the oil pipeline leakage detection method is not satisfactory on small leakage problem, without more accurate warning and location. This paper uses discrete wavelet…
Biodiesel has emerged as a viable alternative to mineral diesel in the transport sector to replace fossil fuels partially. However, long-term compatibility with engine hardware must be evaluated to ensure a smooth transition. Long-term material…
The water-soluble fraction (WSF) of an oil contains different classes of petroleum hydrocarbons and, despite their low potential for bioaccumulation, these can be highly toxic to biota. Nematodes are usually the most abundant and species-rich group…
The aim of the present work is to provide further guidance into better understanding the production mechanisms of soot emissions in Spark-Ignition SI engines fueled with compressed natural gas. In particular, extensive experimental investigations…
The leakage detection system based on negative pressure wave method has been widely applied to crude oil pipelines. Aiming at its shortcomings in reducing false alarms and improving location precision, a combined Kalman filter - discrete wavelet…
Sulfur presented in fuel creates a great problem to environment, human and as well as to the efficiency of various refineries processes rather than sulfur compounds effects during separation transportation, and storage. In the present work,…
