Use of biotechnology in the oil industry is almost unknown. As a whole, only a few initiatives related to use of biofiltration for gas treatment has reached refining operations. In the exploration and production segment of the oil industry, MEOR has been known and employed to a certain extent in secondary or tertiary recovery of oil.

BIOFILT - Biofiltration Column for Removing Ketone from Air System... 

Fig. 1 Steady-state biofiltration column with countercurrent flow.

The program BIOFILT solves the steady-state countercurrent biofiltration operation for MEK removal. The integration is started at the top of the column by assuming a desired concentration in the outlet air. The required column length is determined when the inlet gas concentration exceeds the actual inlet value.

The primary system for controlling VOC emissions from automotive vehicles is the catalytic converter, described earlier in this chapter (see "Oxides of Nitrogen on pages 24-33). A number of different technologies have been developed for removing VOCs from flue gases of stationary sources. They include thermal and catalytic incineration, adsorption, absorption, and biofiltration. 

Similar Ti02 nanotube array membranes of uniform pore size distribution were prepared also recently by Paulose et al and tested in biofiltration applications. The size of the membranes was 12.5 cm , a size limited by the processing equipment. These membranes can be used in lab-scale tests, but are fragile.
