Abstract
A method for removing natural gas liquids from raw natural gas involving the steps of: passing untreated gas through a scrubber to remove liquid droplets and contaminants; delivering the untreated gas to a compressor, which pressurizes the untreated gas to create pressurized gas; passing the pressurized gas through a first aerial cooler to discharge heat to atmosphere; providing a chilled air exchanger and an air chilling unit; chilling air by passing the air through the air chilling unit to create chilled air; delivering the chilled air to the chilled air exchanger; passing the pressurized gas through the chilled air exchanger to cool the pressurized gas to a setpoint to create cooled pressurized gas; and delivering the cooled pressurized gas to a separator to remove liquids from the cooled pressurized gas, thereby creating processed gas. A system having the components listed above.
