New engine diesel pollution is addressed in the U.S. Environmental Protection

Agency (EPA) Clean Diesel Truck and Buses, low sulfur diesel, and nonroad diesel

rules.  Unfortunately, slow fleet turnover will extend full implementation.  EPA

is interested in both retrofit technologies that reduce emissions (particulate

matter, volatile organic pollutants, NOx) from diesel sources and new biodiesel

implementation technologies.

In this Phase I project, Compact Membrane Systems, Inc. (CMS) will address

both of these issues.  Ethanol-diesel fuel blends have shown that they

can reduce many emissions (particulate matter, volatile organic pollutants,

CO) by more than 20 percent.  Unfortunately, the ethanol-diesel (e-diesel)

fuels do not affect significantly NOx emissions.  CMS proposes the simultaneous

use of e-diesel fuels with retrofit membrane technology.  The latter retrofit

membrane technology already has demonstrated an ability to reduce NOx emissions

by more than 50 percent with no significant change in other emissions.  Both

e-diesels and CMS membranes are easily retrofitable technology, which is one

to EPA’s key objectives.  In addition, ethanol prices ($/gallon)

are significantly lower than other biodiesel sources, and ethanol’s BTU/$

is much higher than other biodiesels.  This project therefore addresses

a second EPA objective related to low-cost biodiesel production technologies.  There

also is special synergy between CMS technology and e-diesel.  E-diesel

is a more combustible mixture and using nitrogen-enriched air from CMS membrane

reduces or controls the e-diesel combustibility, which is desirable.

In Phase I, CMS will demonstrate on a 20 kw Lister-Petter diesel engine using

an appropriate ethanol-diesel fuel blend and appropriate controls that low-cost,

ethanol-based biodiesel in combustion with novel CMS retrofit membrane broadly

reduces emissions by at least 20 percent across the board with no significant

(less than 2 percent) fuel penalty.

CMS has established key relationships with major industrial and industrial

membrane companies.  These relationships will enhance CMS’s ability

to be successful in Phase I/Phase II and subsequent downstream production.
