Venturi Scrubber Optimization

The moniker “workhorse” certainly applies to the venturi-type wet scrubber for air pollution control. It got its reputation (and application in thousands of wet scrubber applications) given its simplicity, reliability, and low-capital cost. Like its packed tower brethren, its simplicity makes it sometimes difficult to optimize. Optimization can result in some added cost that is therefore in conflict with its reputation for low cost. Also, as mentioned in the chapter on Venturi scrubbers, improving its removal efficiency often results in an increase in power consumption whether that increase occurs at the prime mover (usually a fan) or at the pump.

There are some things to be considered however to optimize ...
