Land Disposal of Waste Gases: II. Gas Flow from Buried Pipes¹

ABSTRACT

Steady-state compressible gas flow in homogeneous soils from buried porous pipes is analyzed for the purpose of developing land disposal systems for waste gases. Two different cases are considered (i) the ground surface is partially covered by an impermeable barrier, and (ii) the surface is corrugated with alternating ridges and valleys with the pipe buried under the ridges. The partial surface barrier provides a more uniform gas flow in soils than without it, but leads to an increase in the power required to inject gas at a given rate, especially when the pipe spacings are wide. Compared to an open level surface, the corrugated geometry results in a better gas distribution with little increase in power required and is probably the better system for injecting waste gas in nonstratified soils.
