Table 4 shows cartridge change-out frequencies in days for each model
heater and gas scrubber for H S and moisture.

CHANGE-OUT FREQUENCY
Table 4 FLO-DRI Cartridge Change Schedule in Days
Example 1: Sour Gas H S
2
Your installation has a Cata-Dyne™ heater, model
The concentration of H S in your gas supply is 25 ppm.
2
The change-out frequency for 10 ppm is 70 days (derived from
Table 4).
COF = 70 days x 10ppm / 25 ppm = 28 days.
The FLODRI-10MS scrubber cartridge should be changed once
every 28 days.

Example 2: Moisture
Your installation has a Cata-Dyne™ heater, model
The concentration of moisture in your gas supply is 25 ppm.
The change-out frequency for 50 ppm is 55 days (derived from
Table 4).
COF = 55 days x 50 ppm / 25 ppm = 110 days.
The FLODRI-10MS scrubber cartridge should be changed once
every 110 days.
