GAS TRANSPORT

Stratospheric source gases - A variety of gases transport chlorine into the stratosphere. These gases are emitted from natural sources and human activities. For chlorine, human activities account for most that reaches the stratosphere. The CFCs are the most abundant of the chlorine-containing gases released in human activities. Methyl chloride is the most important natural source of chlorine ... 

Flow Equation (2) Gasification Reagent Transport Equation (3) Product Gases Transport Equation (4) Cavity Evolution Equation and (5) Cavity-Dependent Permeability Equation. We have implemented these equations into and solved by FASTFLO, a powerful commercial PDE solver for multiphysics. These equations are defined as...

Toxic gases transportation risk assessment is usually used to find high-risk parts of transport route, compare more possible transport routes or regulate transport through rural areas, thereby transportation risk assessment can involve solution of all risk task categories. Five task categories are described in this paper, i.e. we consider 1st, 2nd, 3rd, 4th and 5th task category. 

Probability of undesired event by toxic gases transport... 

In toxic gases transportation are varieties of potential release mechanisms that are not induced by traffic accidents. Typical non-accident releases are leaks that develop at valves or fittings. Truck tanks may be overfull, relief valves and rupture disks may fail, resulting in a release of transported gas. 

Released toxic gas can have injuring or lethal effects with stochastic character for people (3rd task category). In toxic gases transportation risk assessment we consider only lethal effects, due to very difficult categorization of injury effects and with it related impracticabdity of several transport routes risk comparison. 

Societal risk from toxic gases transport Societal risk in risk receptors grid cell is equal to sum off expected number of deaths Nd,ceU in the grid cell for all risk receptors grid cells (5th task category) ...

The sample-handling and conditioning system must extract a representative sample from a flowing pipeline, transport the sample to the an yzer, condition the sample to be compatible with the analyzer, switch sample streams and calibration gases, transport excess sample to recovery (or disposal), and resist corrosion by the sample.
