Sulphur Recovery Unit

The commissioning of our refinery’s sulphur recovery unit in 2008 has contributed to a 55% reduction in SO2 emissions.

Sulphur Recovery Unit

Over the past several years, our refinery has aggressively targeted the reduction of sulphur dioxide (SO2) emissions through improved processes and the installment of new control technology. These efforts have led to an overall reduction of SO2 emissions by 55 percent between 2003 to 2009.

In 2008, our company invested $70-million in a new “tail gas” or sulphur recovery unit, which chemically strips out the sulphur from the tail gases and transforms it into a molten form of sulphur that can then be recycled. Due to the additional recovery of sulphur from this unit, the refinery’s SO2 emissions are among the lowest of all Canadian refineries, and approximately one-third of the government’s permissible emissions rate.
