Petrochemical and Gas Plant Noise

The construction of new or expanded petrochemical, LNG or gas storage plants can mean a significant increase in noise to the environment. Large areas of land and many residents can be affected.

Controlling noise from gas plants or petrochemical plants is difficult because of their sheer size and the large number of sources. Computer modelling is an important tool in early petrochemical plant noise design work at the Feasibility/FEED stages of the project. Simulations using ISO 9613 propagation methods generate noise contours both on-plant and in the surrounding community. Predicting noise levels radiated from pipework throughout the site is also one of our key specialisms and adds to the model accuracy.

Spectrum has worked on some of the largest engineering projects in the world including the world’s largest greenfield oil refinery Reliance Jamnagar, India, where we acted as noise consultant to Bechtel in a project to increase capacity from 27 to 40 MTPA. Also the new 60 billion US$ Kashagan Oilfield development in Kazakhstan.

Other projects include:

  • ADNOC OGD1 and 2 gas treatment complexes, Abu Dhabi for Technip-Bechtel JV
  • Burullus gas plant, Egypt for Bechtel
  • Onshore drilling rig noise studies in UK, Denmark, Holland and Norway
  • Gas storage facilities in UK at Aldbrough, Holford, Satlfleetby and Hole House for SSE, E.ON, Wingas and Edf Energy
  • Process valves noise reduction study, for Equate Petrochemicals, Kuwait
  • Gas compressor stations at Wormington, Churchover and Felindre, UK for National Grid
