Soundproofing for Industrial Plants – Stopson Italiana

Industrial plants operate in critical conditions that generate significant sound levels. Noise management is not just a matter of comfort, but a regulatory, environmental and functional requirement.

STOPSON Italiana designs and supplies advanced acoustic solutions to reduce the sound impact in numerous industrial contexts, ensuring legislative compliance and business continuity.

The approach is completely tailor-made: each system has unique characteristics and therefore requires an integrated/dedicated design that takes into account temperature, pressure, metric/volumetric dimensions, environmental conditions and acoustic requirements.

Sectors of Application

Oil Gas Extraction Treatment

Natural gas and oil extraction and processing plants are extremely noisy environments, where compressors, valves and turbines are the main sources of abnormal noise emissions.

Noise emissions can reach critical levels, affecting operator safety and regulatory compliance. In addition, the often extreme operating conditions (high pressures, ATEX environments, exposure to sand or salt) require robust solutions that are resistant to time and bad weather and therefore durable. Our expertise in bespoke design allows us to provide acoustic systems that can be integrated into onshore and offshore stations, ensuring high performance even in harsh environments.

Solutions provided:

  • Modular soundproofing cabins for compressors and turbines
  • Silencers for control, safety and blow-down valves
  • Systems compatible with liquefied natural gas (LNG) and cryogenic conditions

The structures are made to withstand the outdoors, in ATEX environments and/or subject to extreme conditions.

Refineries, petrochemicals and gas transportation

Refineries, petrochemical industries, and gas transportation networks include continuous processes with high-energy flows, multiple valves, and noisy pumps. Acoustic problems occur both inside the systems, compromising operating comfort, and externally, increasing environmental noise pollution. Installed systems must withstand high temperatures, corrosive agents and often work in confined spaces. STOPSON Italiana manufactures acoustic solutions suitable for both new systems and modernizations, ensuring integration with existing networks and pressure equipment. Solutions provided:

  • Cabins and barriers for areas with valves and instrumentation
  • Integration with pipelines and compressor stations
  • Designs for corrosive and high-temperature environments

Power plants, cogeneration and trigeneration

In these plants, the simultaneous presence of gas turbines, generators and heat exchangers generates a combination of complex and continuous sound sources. In addition to engine and exhaust noise, there are emissions related to steam flow, chimneys and ventilation systems. Noise reduction is essential to ensure safety in the power plant, reduce sound propagation to the outside and maintain the efficiency of the equipment. STOPSON Italiana designs high-performance silencers, capable of operating in environments with high temperatures, variable pressures and frequent thermal cycles.

  • Silencers for exhaust ducts and by-pass chimneys
  • Silencers for steam systems and blow-down valves
  • Soundproof cabins for generators and auxiliary components

All systems are designed with the ultimate aim of achieving fluid dynamic optimization and therefore resistance to high temperatures.

Heating systems and industrial boilers

Industrial boilers and thermal systems are responsible for noise emissions related to combustion, forced ventilation and flue gas exhaust. Noise can be amplified by resonance effects within ducts, especially at low frequencies. In addition, the systems often operate near sensitive areas, where noise limits are more stringent. STOPSON Italiana solutions take into account the entire configuration of the system, intervening with silencers designed to minimize pressure drops and resist corrosion or condensation phenomena.

  • Silencers for chimneys and combustion fans
  • Solutions for oil and HRSG boilers, even in urban environments
  • CFD analysis for resonances and optimal placement

From all the factors mentioned in the design, the most important points are dew point, corrosion and pressure drops.

Industrial generators and generators

Industrial generator sets, used both as a main source and as a backup, are among the noisiest pieces of equipment in the industrial sector. The noise produced by endothermic engines and exhaust systems can far exceed the permitted limits, especially in civil or semi-industrial environments. It is essential to ensure maximum sound reduction without compromising ventilation, accessibility and cooling. STOPSON Italiana manufactures complete soundproofing cabins and customized silencers, able to adapt to any configuration, both outdoor and indoor.
