Case one
1 amine liquid application analysis
About 200 tons of alkanolamine solutions of two combined workshop of Qingdao petro-chemical corporation, are two by catalytic unit and sulfur recovery facility
Set disused aine liquid, which is mixed, carries out concentration regeneration treatment.The heat stable salts content of mixed amine liquid is 3.24%, suspension content
194ppm, sodium ions content 7783ppm, chloride ion content 6093ppm；Amine liquid is in bronzing, muddy.In addition, in
Petrochemical industry general headquarters about being explicitly pointed out in oil refining process anticorrosion administrative provisions detailed rules for the implementation, amine liquid heat stable salts content no more than
1%.
As amine liquid heat stable salts content increases, the enhancing of amine liquid solvent corrosion, the especially oxalic acid of amine liquid degradation generation
The components such as salt, acetate, formates, chloride have a direct impact apparatus corrosion, and chloride ion etc. is easy to and carbon steel surface
Ferrous sulfide protective layer reaction, generate deliquescent complex compound, protective layer is stripped and is destroyed, in carbon steel equipment pipeline
Wall gradually corrodes and is thinned, and this also increases the security risks of equipment.Solid suspension content in amine liquid is higher, and a part is come
The insoluble matter generated derived from the degradation of amine liquid, a part wash away the particulate matter (such as ferrous sulfide) of generation from corrosion of piping.It is outstanding
Floating particles object will affect the stability of solvent foaming to a certain extent, and amine liquid is easily caused to foam when contacting with high-speed flow, protect
The cleaning for holding amine liquid solvent can be effectively improved the foaming tendencies of amine liquid.
