Oil/water Separation

When we discuss about oil/water separation, we can really show the support evidence that makes our tubular organophobic ceramic membrane a superb membrane.

Here we present the analysis of oil/water separation of samples taken from our molecular filtration process. The feed was from an oil field in Texas.

Gas chromatography-mass spectroscopy (GC-MS) analysis were performed using Agilent Technologies 6890 N GC configuration equipped with a 7653 series injector and a 5973-series Network mass selective detector. The HP5-MS capillary column (model no. 190915-433; 30.0m x 250mm x 0.25mm) was operated with a 0.2 mL injection-volume and a constant 1.2 mL/min flow rate. The oven method was as follows: (1) 50 ˚C - hold time 2 min.; (2) 50-200 ˚C at 10 ˚C/min., hold time 45 min.

In order to run samples on the available column, the organic phase was extracted into a column-compatible media, i.e. a non-aqueous matrix, by shaking the original aqueous samples with chloroform and toluene. Organic phases were then dried over anhydrous MgSO4 and stored at ca. 0 ˚C until immediately prior to use. Reference spectra for MS data were taken from the NIST spectral libraries using Agilent Technologies' Enhanced ChemStation, version D.00.00.30 Total organic content (TOC) analysis was performed using a Shimadzu TOC-VCSH analyzer.

Regarding the data collected via GC-MS, the majority of peaks present in the initial feed stream are also present in the concentrate, albeit having slight variance in percentages with respect to one another (see Figure 2 and Figure 3). Perhaps more importantly, however, is the fact that the permeate stream fails to show any organic content (within the detection limits of the instrument used; see Figure 4), which is in agreement with the TOC analysis (Figure 1), showing appreciable organic content in both feed and concentrate streams, but almost negligible quantities in the permeate stream. The permeate total ion chromatogram (Figure 4), is in stark contrast to those observed for the feed and concentrate.
