Abstract: Urban natural gas purification plants are crucial infrastructure for socioeconomic development and energy structure optimization. However, the noise issues arising during the operation of urban natural gas purification plants pose a threat to occupational health and the surrounding residents. In this paper, the current situation of noise pollution in urban natural gas purification plants is introduced; and the source intensity, frequency characteristics and propagation influence of the main equipment noise are analyzed. Based on the actual noise levels of equipment at urban natural gas purification plants after commissioning, this paper focuses on analyzing targeted noise control measures and their corresponding noise reduction effects for noise sources identified onsite, and provides insights into future noise control strategies along with relevant recommendations. The analysis and recommendations presented herein can serve as a reference for similar engineering designs.

Key words: natural gas purification plants, noisesources, plant boundary noise, noise reduction devices, noise control
