Scrubber Level System Tools

Scrubber Level Control System Emissions Calculator (.xls, 613KB)
The SLS Emissions Calculator allows you to plug in application information, such as ambient temperature, dump frequency, dump rate and supply pressure, and provides the total system emission of gas per hour.

DVU Selection Guide (.zip, 327KB)
The DVU Selection Guide selects the appropriate dump valve model for the user using a series of calculations. This calculation is obtained after the user inputs application information such as diameter of vessel, duration of dump cycle, vessel pressure and pressure at outlet of DVU.
