As it is commonly known, syngas is an alternative for the coal and using syngas instead of the coal leads to 'clean energy' generation. mol), Suppose you are holding a container of gas, and the container has a fixed volume (i.e. 0 0 _ ) ; [ R e d ] \ ( [ $ - 2 ] \ # , # # 0 . Required fields are marked *. Air volume calculation formula: equipment air volume = room volume (length width height) ventilation constant (60-100 times), the constant here can be determined according to the working time. Clarification on the time allowed for this project of scrubber elementary design should have been given.
