Acetylene content in calcium carbide slag

Which friend knows what the approximate acetylene content is in calcium carbide slag
The acetylene content in calcium carbide slag is usually very low, as most of the acetylene has been extracted and utilized during the production process. The specific content depends on the production process and conditions, but generally, the residual amount of acetylene is very low. If accurate data is required, it is recommended to obtain it through experimental testing. .
Generally, in the absence of accidents, trace amounts in high-temperature environments
Acetylene is only slightly soluble in water. When producing acetylene from calcium carbide, whether using a dry or wet method, the reaction temperature remains high, as the reaction between calcium carbide and water is exothermic. Therefore, even when acetylene is produced by the wet method, no significant amount of acetylene enters the water. Furthermore, during the purification of acetylene to remove impurities, although there are situations where it comes into contact with water, the amount of acetylene dissolved in the water is very small. It should be noted, however, that when water treated with acetylene is discharged directly, precautions must be taken to prevent explosions in that water.
In the wet calcium carbide process for acetylene production, the acetylene content in the overflow slurry is relatively high. The acetylene in these slurries exists mainly in the form of dissolved acetylene and unreacted calcium carbide nuclei, with concentrations generally ranging from 250 to 400 mg/L.
When water that has been treated with acetylene is discharged directly, precautions must be taken to prevent explosions; are there any regulatory requirements regarding this? Since the acetylene content in the discharged water is low, the wastewater can at most be classified as Category C
Same question: we are also involved in acetylene production. Is there any standard for this?
