Other Concerns about Chemical Plants Noise
There is a considerable amount of noise in the manufacturing of chemicals because of the use of large machines, compressors, turbines, and other types of heating and cooling equipment. If the pressure within an operation has to be suddenly released, it causes considerable additional noise.
Best Practices to Mitigate Noise
- • Place the buildings, especially the larger ones, in such a way that they will act as noise barriers from known sources of noise.
- • Use low noise generation equipment.
- • Use acoustic insulating barriers.
- • Use trees as a shield against noise being released into the community.
- • Develop and implement a stringent maintenance program for equipment and facilities.
- • Replace older equipment on a periodic basis and utilize a new generation of lower noise and lower vibration systems.
Odors typically come from fugitive vapor releases, wastewater treatment plants, transportation sources, and release of dust during unloading and transfer of raw materials and fuel.
Best Practices to Mitigate Odors
- • Determine the major source of leaks and correct them immediately.
- • Clean up all spills as rapidly as possible.
- • Eliminate leaks from equipment by use of proper maintenance on a scheduled basis and as needed.
- • Use dust suppression techniques in all areas where materials are being transferred. Decommissioning a Chemical Manufacturing Facility
When a chemical manufacturing facility is no longer going to be used, there is an extremely serious concern about the remnants of hazardous materials that may be present in or on the equipment, in the facility, or on the surrounding grounds, as well as potential leakage into ground or surface water and the air.
Best Practices in Decommissioning a Chemical Manufacturing Facility
- • Conduct a complete survey of the entire facility, grounds, equipment, ground and surface water supply, and air and record the current levels of chemicals present as well as quantities in storage and/or waste.
- • Establish a complete plan of decommissioning with all steps involved and all necessary checks and balances including testing programs.
- • Determine the most effective means of cleaning all equipment and facilities, and establish a program with highly trained individuals using proper personal protective equipment to carry out the task.
- • Determine with the help of the regulatory agencies and using best industry practices how to remove the hazardous chemicals including spent catalysts in a safe and secure manner and reuse them wherever possible.
- • Determine if the facility can be used for other purposes in some form of manufacturing process.
- • Determine if the facility should be torn down after decontamination and the equipment be removed for other purposes.
- • Determine the safety of the soil and the levels of contamination found there. If contaminated, follow the techniques stated later on how to process contaminated soil and turn the site from one which is hazardous to one which can be reused.
