Flue gas cleaning by periodic absorption

Simulations and designs are presented of conventional and periodic SO2 absorption from exhaust gases using salt water as absorption solvent. Operating conditions resemble those of a maritime operation, involving relatively small amounts of SO2, so the separation is in the linear region. The advantages of periodic operation, as already demonstrated for conventional distillation remain valid for absorption processes: Less tall towers, than staged towers are possible, or substantially less salt water is required for the process employing periodic cycling.

Automated summary

Simulations and designs are conducted on conventional and periodic SO2 absorption using salt water as solvent for exhaust gases. The advantages of periodic operation, such as shorter towers and less solvent required, are applicable to absorption processes as well.
