Stages of Operation
Stage 1: Inlet Particulate
& Coalescing Pre-Filter
The pre-filter removes particulates, water aerosols, and
oil mist content efficiently. The pre-filter is equipped with a
differential pressure indicator and a Zero-loss automatic
condensate drain valve.
Stage 2: 13X Molecular
The inlet portion first layer of the adsorbent media
filled in the towers is 13X molecular sieve to remove contaminants
such as volatile organic compounds, acid forming gases, base gases
Stage 3: Activated
This layer of activated alumina removes moisture to a
dewpoint of -40Â°F and below at line pressure.
Stage 4: Carulite
The catalyst layer is used to convert carbon monoxide to
carbon dioxide and to oxidize residual hydrocarbon vapors.
Stage 5: Activated
This final layer of activated alumina is installed at the
top of the towers to remove residual contaminants.
Steps 2-5: The
towers adsorb and regenerate alternatively. The regeneration of
this unique multi-layer adsorbent media and catalyst arrangement
typically extends its life under normal conditions to three to five
years. The control system sequence is monitored by a standard fail
to switch system using pressure transducers and alarms when the
system does not function properly.
Stage 6: Activated Carbon
The activated carbon contained in the filter element
assures a residual oil vapor content below 0.003 ppm. The filter is
equipped with a manual ball valve.
Stage 7: Sub-Micron
The final-filter efficiently removes fine aerosols and
particulates generated in the system. The filter is equipped with a
differential pressure indicator and manual ball valve.
The outlet air is monitored by a high
quality Carbon Monoxide (CO) analyzer and triggers an alarm when a
preset level is reached.
