Abstract
An essentially adiabatic process for the crossflow scrubbing of particulate material from a gas is disclosed in which the scrubbing liquid is recirculated without cooling. By a combination of a minimum gas temperature of about 150.degree.F., saturation conditions, and a certain amount of turbulence, it has been found possible to achieve particulate nucleation prior to passage of the gas through the scrubber units which, in turn, makes it possible to recycle the scrubbing liquid while maintaining it at a substantially constant temperature.
Claims16
A process for treating an effluent gas containing entrained particulates a portion of which are below 1 micron in size and acid gas components, said gas having a temperature above 150.degree.F., which comprises:
- a. initiating nucleation of the particulates in a first enclosure by treating the gas to increase its turbulence and to increase its humidity substantially to saturation at a temperature above about 150.degree. to about 212.degree.F. under substantially adiabatic conditions;
- b. passing said saturated gas which is at a temperature above about 150.degree. to about 212.degree.F. in a substantially horizontal path through a second enclosure containing packing;
- c. passing an aqueous scrubbing liquid downwardly over said packing;
- d. exhausting said gas from said second enclosure;
- and,
- e. collecting said liquid after passage through said packing and recirculating said liquid to said packing while maintaining it at a substantially constant temperature approximately the same as the saturated gas which is above about 150.degree. to about 212.degree.F.
