Process flowchart or PFD is also known as the system flow diagram or SFD. The main reason of using process flowchart is to show the relation between major parts of the system. Process flowchart or PFD does not include minor parts or components of the system like piping ratings or piping systems. In ...

Coal seam gas (CSG) is natural gas mainly composed of methane, the odourless and colourless gas used in homes and businesses. Natural gas from coal seams is used in exactly the same way as other natural gas, for cooking, heating, electricity production and to make products such as fertilisers.

Therefore, the gas migration in coal seam is a coupled process in which the gas flow and solid mechanical deformation interact with each other. This process becomes more complex when the gas content, which depends on gas pressure and solid deformation, and the Klinkenberg effect, which reflects the effect of gas pressure on the gas

What is coproduced water? Coal seam gas is a natural gas held in coal seams under pressure by groundwater. Coal seam gas wells release the gas by reducing the pressure through groundwater extraction. Extracted water and gas is diverted to surface infrastructure treatment and processing plants (Figure 1). The extracted water is termed 'coproduced water' (also referred to as

Flowback is also used to get an indication of the amount and type of reservoir fluid (oil, gas, water) that can be produced and at what pressure, if any. Flowback is very much associated with producing natural gas or shale gas through shale rocks using horizontal drilling and hydraulic fracturing.

Burial of coal also generates natural gas (principally methane) and no oil. The methane generated from coal may become stored in fractures in the coal seam as coal bed methane, which is a hazard in underground coal mining, but can also be exploited economically.

A typical Process Flow Diagram (or PFD) explains the process for pygas processing or pygas hydrotreating. Pyrolosis gasoline or pygas (C5+ cut) is a liquid byproduct derived from steam cracking of various hydrocarbon feedstocks in olefin plants. A typical Process Flow Diagram (or PFD) explains the process for pygas processing or pygas ...

This allows the gas to separate from the coal (desorb) and flow through fractures within the coal seams to the well and on to the surface. In general, producing natural gas from coal ... Exploration for natural gas from coal seams involves the search for a particular set of geological ... Figure 34 Gas compression and treatment process ...

This reduces the pressure in the coal seam and allows the gas to be released. Horizontal or angled wells can also be drilled to reach the coal seam. If the flow of gas is insufficient, the coal ...
