Abstract
An air treatment system and method that uses inertial moisture separators in two stages for removing moisture present in intake air entering the air treatment system, thereby increasing the effectiveness and lifespan of high efficiency filters that otherwise may become clogged by accumulating moisture.
Claims17
A multi-stage filtration system comprising:
- a first inertial moisture separator in a first stage of the filtration system for removing moisture present in air entering the filtration system;
- a coalescing first filter in a second stage of the filtration system for removing particulate matter and for coalescing moisture present in the air that has passed through the first stage of the filtration system;
- and
- a second inertial moisture separator in a third stage of the filtration system for removing coalesced moisture present in the air that has passed through the second stage of the filtration system.

A filter house comprising:
- an air intake hood;
- a first inertial moisture separator in a first stage of the filter house behind the air intake hood, the inertial moisture separator configured to remove water droplets from intake air entering the filter house;
- a coalescing pre-filter in a second stage of the filter house configured to remove particles in the air that has passed through the first stage of the filter house and to coalesce water droplets in the air that has passed through the first stage of the filter house;
- and
- a second inertial moisture separator in a third stage of the filter house configured to remove from the air that has passed through the second stage of the filter house water droplets coalesced by the coalescing pre-filters.

A method of filtering air to be used in a gas turbine, the method comprising:
- removing water droplets from incoming air using a first inertial moisture separator;
- after the step of removing the water droplets, filtering particles from the incoming air and coalescing water droplets that have passed through the first inertial moisture separator;
- and
- after the step of filtering particles and coalescing water droplets, removing water droplets from the incoming air using a second inertial moisture separator.
