Steam Distillation Studies For The Kern River Field
SPE Western Regional Meeting, 1997Abstract The interactions of heavy oil and injected steam in the mature steamflood at the Kern River Field have been extensively studied to gain insight into the effect of steam on compositional changes of oil during the recovery process and to provide input for compositional thermal simulation.

Abstract A new extraction process, i.e., ohmic accelerated steam distillation (OASD), was designed and developed in this study. A packed bed of lavender inflorescences was subjected to OASD and extraction parameters, physical, and chemical properties of the extracted essential oil were compared to that of SD. The proposed extraction technique yielded

Steam Distillation Drive-Brea Field, California
Journal of Petroleum Technology, 1972This process has been field tested in a steeply dipping reservoir containing 24 degrees API oil at a depth of 4,600 feet. The very stable steam drive showed little tendency for early heat breakthrough to downdip wells. Residual oil saturations of 8 percent were achieved and the produced oil gravity was increased by light components distilled from the ...

Compositional Changes in Distilled, Steam-Distilled, and Steamflooded Crude Oils
Proceedings of SPE Western Regional Meeting, 1992ABSTRACT Steamflooding of heavy and especially light oil reservoirs involves steam distillation of reservoir fluids. Accurate description of the steam distillation behavior of the reservoir oil is required in evaluation of reservoirs for steamflood potential and in the numerical modeling of reservoir performance using compositional ...

A Compact Steam Distillation Apparatus
Journal of Chemical Education, 1996The commonly used steam distillation apparatus contains two parts. In one part the steam is generated while in the other part the compound/material is distilled. Both parts are heated separately. This apparatus is complicated and difficult to handle. In view of this, a very compact steam distillation apparatus is designed and reported in this paper. In

Cinnamaldehyde by Steam Distillation of Cinnamon
Journal of Chemical Education, 1998Powdered cinnamon foams badly on attempted steam distillation. It has been demonstrated that preliminary iterative evacuation of the aqueous mixture allows smooth distillation of cinnamaldehyde (I).

Determination of phenols using simultaneous steam distillation–extraction
Journal of Chromatography A, 2000Simultaneous distillation-extraction was proposed as a preconcentration step for the determination of phenol and its derivatives in aqueous and soil samples. Detection limits of 0.01 mg l(-1) (water) and 0.1 mg kg(-1) (soil) were achieved by gas chromatography-flame ionization detection.

Journal of chromatography. A, 2008
Steam distillation (SD) is routinely used by analysts for the isolation of essential oils from herbs, flowers and spices prior to gas chromatographic analysis. In this work, a new process design and operation for an improved microwave steam distillation (MSD) of essential oils from aromatic natural products was developed. To demonstrate its feasibility,

Model Evaluation of a Steam Distillation Process for Steam Temperature Regulation
2012 Third International Conference on Intelligent Systems Modelling and Simulation, 2012Steam temperature of a steam distillation process possessed variable process gain and a significant dead-time when operating from 27oC to its saturation point. Model accuracy is an important factor when tuning a PID for temperature regulation using model-based method such as open-loop Ziegler-Nichols. This study will evaluate the adequacy of two models;
