SRU solutions Dynawave® reverse jet scrubber
Claus Sulfur Recovery Units (SRU) are found in various industries, such as refineries, natural gas processing plants, chemical plants, and coal gasification facilities. The Claus process is widely used to recover sulfur from HS containing gas streams. However, a Claus SRU can typically recover only 95 – 98% of the sulfur present. Many times, Tail Gas Treatment Units (TGTU) are installed downstream of a Claus SRU to increase the overall sulfur recovery to 99.0 – 99.9% in order to comply with local environmental regulations. ese TGTUs may include amine-based TGTUs (SCOT type), cold-bed sub-dewpoint processes (SULFREEN,® CBA, etc.), or direct oxidation type processes (SUPERCLAUS,® EUROCLAUS,® etc.).
Depending on the sulfur recovery efficiency provided by the SRU/TGTU combination, local environmental regulations for SO emissions may be met normally. However, operations during start-up, shutdown and malfunction upsets may require further treatment downstream of the TGTU, or treatment as an alternate/redundant operation to the TGTU. is is where the DynaWave® wet gas scrubbing technology can provide reliable and worry-free operations, and guaranteed SO removal to meet environmental regulations and good neighbour objectives.
Worry-Free Simple and Robust Design
DynaWave® is a unique open bore, reverse jet scrubber that utilizes “Froth Zone” technology to perform desulfurization in a wet gas environment. Is proven technology will reduce total installed cost, simplify operations and deliver over 99.9+% sulfur removal.
