(Luo et al.
While cold water falls downward through the packed tower
, hot air from a forced-draft, gas-fueled burner rises upward - transferring 99% of the air heat to the water.
Hydrogen sulfide gas formed during the process is collected and vented through drums of specially-coated carbon; a packed tower
scrubber, which is more efficient, may replace the carbon if air emission standards are more stringent.
Assuming a knowledge of proper plant operations, the volume focuses on identifying and correcting a variety of problems including distillation tray malfunctions, packed towers
, heat extraction and pump-around techniques, steam condensate collection systems, vapor liquid separation vessels, vacuum systems and steam jets, turbine drivers and centrifugal compressors.
Sharp's design included two packed towers
and a venturi scrubber.
Although random packed towers
facilitate more mass transfer by providing a larger area in a relatively smaller volume.
Founded in 1969, Curtis Kelly has proven a reliable fabricator of a wide range of products including reactors, packed towers
, trayed towers, blend tanks, storage tanks and vessels, separators, cryogenic equipment, demethanizers, and jacketed equipment.
