Title:
NATURAL GAS PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/125965
Kind Code:
A1
Abstract:
[Problem] To provide a natural gas processing device that can reduce noise generated by an air-cooled heat exchanger that cools a fluid to be cooled that is handled inside the natural gas processing device. [Solution] Provided is a natural gas processing device that performs at least one of liquefaction of natural gas or separation and recovery of components contained in same. An air-cooled heat exchanger 6 supplies, by a fan 62, air for cooling a fluid to be cooled flowing in a tube 63 of a tube bundle 630. An active noise reduction mechanism 70 detects, with a sound detecting unit 71, sound waves propagating in a space through which air for cooling flows, and emits to the space, with a sound emitting unit 72, sound waves for noise reduction with an inverted phase to the detected sound waves and with the same sound pressure and the same wavelength as the detected sound waves.
