Breakthrough time

WebJul 24, 2024 · The image above represents chemical breakthrough time. To compute for chemical breakthrough time, two essential parameters are needed and these parameters are Thickness (l) and Diffusion Coefficient (D). The formula for calculating chemical breakthrough time: t b = l² / 6D. Where: t b = Chemical Breakthrough Time. l = … WebAt breakthrough time: Where, t bt = Breakthrough time, q t = Total injection rate, L = Medium length. From eq. (4‑24): Where PVI is the pore volume injected. So: The average water saturation in the reservoir at the time of breakthrough is given by material balance as: From eqs (4-26) and (4-27):
