In order to improve the administrative level of pipeline safety among the surrounding environment, this paper proposes a pipeline risk assessment system of space and visualization based on the current situation of the gas pipeline risk assessment. The database of pipeline surrounding natural environment and social environment are established by using GIS. And the scatter grams on the accident s...

Free spans or suspended spans normally occur in subsea pipelines due to the irregularity of seabed and byscouring phenomena around the installed non-buried pipeline. The hydrodynamic around the pipeline canlead to a vibration of the pipeline.This kind of vibration may cause fatigue damage to the pipeline. In orderto study the hydrodynamic around the pipeline, calculating the natural frequency o...

security of energy is the major concern of the world, especially the large industrial countries. countries of central asia and the caucasus are the most important countries in the field of energy resources and energy transfer. of the eight countries of central asia and the caucasus, azerbaijan, kazakhstan, turkmenistan and uzbekistan has in total 3.2 percent crude oil reserves and about 14 perc...

Currently there are significant amounts of natural gas that cannot be produced and treated to meet pipeline specifications, because that would not be economically viable. This work investigates a bench scale multistage fluidized bed (MSFB) with shallow beds for sour gas removal from natural gas using a commercially available supported amine sorbent. A MSFB is regarded as a promising adsorber ty...
