Discussion on the design of hazardous waste warehouses in petrochemical enterprises
Thread Content
In recent years, as environmental and safety regulations have become stricter, new petrochemical plants, as well as those undergoing renovation or expansion, are required to establish new hazardous waste storage facilities for storing things such as waste catalysts, waste residues, and used engine oil. At present, the main standard is the \"Pollution Control Standards for the Storage of Hazardous Wastes\" (GB18597-2001), but it does not contain specific and detailed provisions. Feel free to discuss the following issues! (1) Are gas and toxic gas alarms required in hazardous waste warehouses, and what standards should be followed for their installation? ； (2) How is the processing capacity of the gas purification device determined, and how is the composition of the exhaust gas defined? (3) The destination of the liquid leakage recovery device: directly to the wastewater treatment plant or into a drain, etc
Personally, I think for this toxic gas alarm, it depends on what the substance in question is and whether it is volatile or not. When there is leakage, it’s necessary to find out exactly what it is. Some of it needs to be sent to wastewater treatment facilities, while some can be poured directly into the sewer.
Specific medium, specific analysis, specific settings
If it is used for storing used engine oil, the fire hazard classification should be Class C, right? Is it then necessary to install combustible gas detectors?
1. Specifically, it needs to be set according to the type of hazardous waste; you can refer to chemical industry standards. For example, gas detectors, smoke detectors, and temperature sensors should definitely be installed； 2. Generally, it is determined based on the number of air changes, which forms empirical data ； 3. Leaks are collected separately, and once collected, they can be sent to a hazardous waste disposal center for treatment.
Does ventilation need to be considered for air exchange? Is it mechanical ventilation or natural ventilation? I don’t understand anything about the handling of hazardous waste
Depending on the specific hazardous waste you are storing, you can refer to the relevant chemical industry standards. For example, with many solvents and substances with a low flash point, forced ventilation is definitely necessary ； If it’s inorganic substances like slag, then it’s simple.
What if it’s about storing Class C solid waste, such as waste wax? Which standards should be followed in the design of the storage facility?
Regulations in some places regarding hazardous waste storage can be used as a reference
How should the fire hazard category of a warehouse storing petrochemical waste catalysts be determined?
