SO? Scrubbing System
The CANSOLV SO2 Scrubbing System uses a tailored amine-based absorbent for regenerable SO2 capture. Rigorous emissions limits can be met (in many conditions down to 20 ppm) while delivering a useful SO2 by-product gas stream (rather than a waste stream), typically converted to salable sulfur, sulfuric acid or liquid SO2.
The CANSOLV SO2?Scrubbing System controls emissions and captures additional value from the SO2?emitted in various flue gas streams, such as those generated by fluidised catalytic cracking units (FCC), process heaters and boilers, power generation plants, sulphur plants, and spent acid regeneration units.
The SO2?can be recycled to the sulphur recovery unit to produce marketable sulphur, converted to salable sulphuric acid, or liquefied for sale on the market.
Recycling SO2 can improve margins and help meet feed specifications.
In certain applications, it can also help to enhance margins. For instance, in sulphur recovery unit applications, capacity can be increased by over 12%. Moreover, marketable by-products are recovered (high-quality SO2, sulphur and sulphuric acid) and there is no solid waste.?
As it is a regenerable system, the Cansolv SO2 scrubbing?system can help to ease many of the environmental and market-induced pressures that are associated with using greater quantities of opportunistic crudes.
