Chemical sewer material selection
Chemical sewer material selection
(OP)
I am having trouble selecting a material for a replacement chemical sewer. At some locations boiler blowdown and steam condensate are discharged, so temperatures can run to 212 F. The combined effluent (blowdown, steam condensate, and process effluent) has a pH of 11.0 - 11.5 (primarily the result of the process effluent). The stream is primarily water with traces of methanol, ammonia, and amines. Much of the water is from the reaction, so it has no hardness (neither does the steam condensate).
System is a gravity sewer and sizes range to 18-inch.
