| Technology Summary: |
| Davison's DESOX SOx
additive offers refiners proven capability to reduce FCCU SOx emissions to achieve
compliance with environmental regulations. DESOX offers the significant advantage
of SOx control without the capital investment requirement of feed hydrodesulfurization or
flue gas scrubbing. DESOX is also used for backup SOx control during FCC feed
hydrotreater shutdowns, to provide flexibility to process sour feeds, to balance
refinery-wide SOx emissions (bubble limit), and for particulate emissions control. |
| DESOX contains a patented
magnesium aluminate spinel which has proven to be the most effective means of reducing SOx
emissions. DESOX reduces FCCU SOx emissions by transferring sulfur, in stable form,
from the regenerator to the reactor, where it is released as hydrogen sulfide for
downstream recovery. |
| DESOX is currently used
by a significant number of refiners to control FCCU SOx emissions. Since the introduction
of DESOX, over 60 refineries with a wide range of unit configurations and operating
conditions have conducted successful tests, including many units operating in partial
combustion. |
| DESOX is the most
cost-effective SOx additive available today, based on commercial testing at several
different refineries. In every case where a comprehensive comparison was completed, DESOX
has emerged as the most cost-effective option for catalytic SOx control, typically by a
two-to-one margin. Despite the claims of our competition, now on their fourth
reformulation, DESOX continues to be the SOx additive of choice for refiners
worldwide. |
