With the increase of the age of the transport oil pipeline, leakages caused by corruption are often found. The public is paying more and more attention to the problems of environmental pollution and economic loss brought by leakage, so a detection…
Factors causing pollution both water and air and fires can be caused by the pollution of liquefied petroleum gas (LPG) that comes from gas network leaks from National gas Company (PGN) to households. For National gas Company (PGN) due to LPG gas…
As negative pressure wave is applied to leak detection and location of natural gas pipeline, the key is how to realize accurate measurement of propagation velocity of pressure wave and time difference. However, there exists problem of lower accuracy…
A new time-frequency analysis method of Hilbert-Huang transform applied in Pipeline leak detection is proposed. Choosing the negative pressure wave signal from dynamic pressure transmitter as research object, the dynamic pressure signal is decomposed…
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,…
Crude oil has become very important source of energy. It is used by industries for supplying energy, providing fuel for vehicles etc. It is carried by submarines pipelines, ships and tankers to industries. Due to carelessness of human beings or…
In this paper, submillimeter three dimensional tomography imaging of paramagnetic contaminants flow rate in multiphase flow pipelines is presented. The device, which is based on Magnetic Particle Imaging (MPI), consists of an array of twelve coils…
A new way of statistical pulsation measurements by radioisotope technique is described. It is an alternative to the existing stream control methods and allows to improve accuracy of measurements. The effect of harmful substances transported in crude…
With economic and population growth it is expected that the shipping sector will continue to grow even further. The negative environmental and health effects of the seaborne trade, which are caused by emissions of greenhouse gases and harmful…
Energy consumption and its environmental impact are now among the most challenging problems in most developing cities. The common sources of energy used as the fuel in transportation sector include gasoline, diesel, natural gas, propane, biofuels,…
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,…
In this paper, an experimental study was conducted using terahertz (THz) spectroscopy to assess the electromagnetic properties in the THz range of various materials that can be found in oil and gas fields. This includes the absorbance, transmittance,…
