BP Refinery - Toledo, Ohio
Key Challenge
The BP refinery in Toledo, Ohio uses “fresh” sulphuric
acid in the production of alkylate, a high octane
component of gasoline and key to clean fuels programs.
Used, or “spent” acid must be regenerated
and returned to the manufacturing process. The
refinery also requires additional capacity to process
excess H2S gas it cannot properly manage and removal
of the sulphur by-product recovered from the refinery’s
H2S processing.
Solution
The Marsulex facility, located adjacent
to the refinery, receives spent acid, H2S gas and
sulphur via pipeline. The spent acid is regenerated
and returned to the refinery as fresh acid via
pipeline. The H2S and sulphur are consumed for
fuel and sulphur value in regenerating the spent
acid to fresh.
Result
- BP environmental regulations
for the control of spent sulphuric acid and H2S
gas emissions are reliably met.
- BP sulphur that
is removed as part of the compliance process
is consumed as a value add fuel/raw material
versus lower market value if sold as a commodity
to third party industrial customers.
- Capital
and operating costs for BP are lower as a result
of economies of scale achieved
by Marsulex providing similar services to
three other local refineries, making Marsulex
the
largest
provider of regeneration services in the
US mid-west.
- Other local oil refinery customers
also benefit from lower processing costs than
they could
achieve on their own.
