Wastewater from flushing the hexamethylenediamine pipeline
Distillation can be used to extract hexamethylenediamine from wastewater containing it. The specific steps are as follows: 1. Heat the wastewater to the boiling point of hexamethylenediamine (approximately 194°C) to cause it to evaporate. 2. Cool the steam through a condenser to turn it back into liquid hexamethylenediamine. 3. The collected liquid hexamethylenediamine is subjected to further processing and purification. It should be noted that safety measures must be taken during distillation to prevent hexamethylenediamine from causing explosions or fires at high temperatures. If hexamethylenediamine is to be recovered and reused, other methods can also be employed, such as extraction and gas chromatography. But this requires choosing the appropriate method based on the specific circumstances. .
Check if the volume is large enough and whether there is value in recycling it. If the amount is small, just treat it as hazardous waste
