Construction of soundproof canopies for turbomachines

Details

Published: 10 January 2025

Turbomachinery has experienced a spectacular boom in recent decades, in relation to diversified applications involving an energy transfer between a rotating part (a rotor) and a fluid. This is particularly the case for combustion turbines, which in simple or combined cycle i.e. when a steam turbine and a large capacity industrial boiler - a Heat Recovery Steam Generator (HRSG) - are involved are capable of producing very large quantities of electricity (their unit power is measured in hundreds...

Noise reduction from gas relief vents

Details

Published: 04 December 2024

In an Air Separation Unit (ASU), gas decompression (relief) vents often allow mixtures of air and Nitrogen (N₂), or pure Oxygen (O₂), to be released into the atmosphere, which makes it necessary to reduce the noise caused, both for the protection of site personnel and for the neighborhood, because the sound power level before soundproofing can exceed 150 dB(A), which is considerable.

If the considered site is in Europe, Directive 2003/10/EC of the European Parliament and of the Council, of...

Reduction of the sound level of noisy industrial equipment

Details

Published: 01 November 2024

The reduction of the sound level of noisy industrial equipment is a necessity in view of various requirements:

• the protection of workers (e.g. assigned to production, operation of machines, process controls and supervision, maintenance) on the considered site: their health is at stake when they are exposed to noise (both with regard to their hearing and to the risks of accident they run when warning and traffic signals for vehicles and machines are not correctly perceived); in terms of...
