Optimal salinity variation

Optimal salinity values directly influence the nature of the ionic groups, while temperature variations (PIT tests) strongly effect the oxyethylene linkages. 

Before the optimal salinity S for and after S for y, the variation of y with Ap is of the same form as predicted by Eq. (29), the optimal salinity being the salinity at which ) wm =y,m- found that p/( =4 0A [55]. This result is in agreement with the 3D... 

Bennett and Barter (1997) discuss the effect of partitioning-dissolution in an aqueous phase of alkylphenol. Specifically, they show that the depletion of this crude oil component affects the chemical composition of the original pollutant. Partitioning at equilibrium can be considered the maximum dissolution value of a compound under optimal solvation conditions. Partitioning-dissolution is obtained by washing the crude oil with saline water at variable temperature and pressure conditions, similar to those in the subsurface. The data reported were obtained using a partition device able to simulate the natural environmental conditions of a crude oil reservoir. The alkylphenol partition coefficients between crude oil and saline subsurface water were measured as a function of variation in pressure, temperature, and water salinity. Preliminary trials proved that the experimental device did not allow alkylphenol losses due to volatilization.
