“…In the experimental program presented in this paper, PAM solution was used as the injected fluid and air or decane was used as the defended fluid. Decane (alkane hydrocarbon, anhydrous, ≥99%, C 10 H 22 ) [ 37 , 38 , 39 , 40 , 41 , 42 ], a major constituent of petroleum, represents the petroleum contaminant in soils [ 43 , 44 , 45 ].…”

Biopolymers are viewed as effective and eco-friendly agents in soil modification. This study focuses on the wettability analysis of polyacrylamide (PAM) solutions for soil remediation. The contact angle, surface tension, and viscosity of PAM solutions were experimentally evaluated in air- and decane-biopolymer solution systems. Furthermore, a micromodel was used to investigate the pore-scale displacement phenomena during the injection of the PAM solution in decane and or air saturated pores. The contact angle of the PAM solution linearly increases with increasing concentration in air but not in decane. The surface tension between the PAM solution and air decreases at increasing concentration. The viscosity of the PAM solution is highly dependent on the concentration of the solution, shear rate, and temperature. Low flow rate and low concentration result in a low displacement ratio level, which is defined as the volume ratio between the injected and the defended fluids in the pores. The displacement ratio is higher for PAM solutions than distilled water; however, a higher concentration does not necessarily guarantees a higher displacement ratio. Soil remediation could be conducted cost-efficiently at high flow rates but with moderate concentration levels.

HIS survey is part of a general plan to coordinate the vapor pressures of the paraffin series by means of the formula:where P = vapor pressure, atm.T and B = the same in abs. temp.,This equation is peculiarly suited for the purpose in that it contains but one coefficient to be evaluated, and the latter varies only about 17 per cent in the longest range exploredthat of octane. Hence a compact plot of A 7-q. t may be made to a scale sufficiently sensitive to represent accurately the entire vapor pres-ure range of a substance. This xi11 be taken up in a later article. It 15 evident that general coordination of a series require< an accurate and consistent set of boiling point3 for use in Equation 1. Since this surrey proved to be somewhat extensive and contained points of intrinsic interest, it was thought best to publish it as a separate article but preliminary to the vapor pressure investigation.Past attempts a t correlating the boiling pointh of the paraffin series hare met with three obstacles: (a) the erratic placing of the boiling points of methane and ethane, (b) conflicting data for propane and butane, and (c) the low boiling points of Kraft (6) for the higher molecular nreiglits, showing a sharp break between octane and nonane.X.

“…model, Fisher Scientific) for 24 h. Decane (Sigma-Aldrich, St. Louis, MO, USA, anhydrous, >99%, C 10 H 22 ) was employed to simulate the oil in oil-contaminated soils. Decane is a constituent of petroleum [46][47][48][49][50][51][52][53][54] and represents the petroleum contaminant in soils due to its interfacial properties, which affect fluid flow patterns in porous media [52][53][54]. Ottawa sands that have different particle size distributions were employed in this study (Figure 2).…”

Abstract:Biopolymers have been employed in many soil applications, such as oil-contaminated soil remediation, due to their environmentally friendly characteristics. This study focused on changes in the wettability and viscosity of polyethylene oxide (PEO) and sodium alginate (SA), according to the variation in concentration and their impact on oil-contaminated soil remediation using biopolymer-decane displacement tests. The contact angle and interfacial tension vary with concentration by adding biopolymer to water; however both parameters yield relatively constant values within the range of 2-10 g/L for the concentration of PEO and SA. In this study, their influence on fluid invasion patterns is insignificant compared to viscosity and flow rate. Viscosity increases with the concentration of PEO and SA, within the range of 0-10 g/L, which causes the biopolymer-decane displacement ratio to increase with concentration. Biopolymer-decane displacement increases with injected fluid velocity. At low flow rates, the effect of the biopolymer concentration on the displacement ratio is prominent. However the effect decreases with an increase in flow rate. Thus both biopolymer concentration and injection velocity should be considered to achieve the economic efficiency of soil remediation. The experimental results for the distribution of soils with different grain sizes indicate that the displacement ratio increases with the uniformity of the coefficient of soils.

Isolation of normal decane from petroleum by distillation and equilibrium melting

Abstract: A midcontinent petroleum was fractionated by distillation into cuts with boiling ranges of 0.5°C; From the cuts boiling in the neighborhood of 172°C.n-decane was isolated by systematic equilibrium melting in a low-temperature centrifuge.
