Claims (11)
1. Förfarande vid framställning av väteperoxid genom antrakinonpro-cessen, i vilken process i en arbetslösning lösta antrakinonderivat utsättes för omväxlande hydrering och oxidering, känneteck-n a t av att arbetslösningen torkas före hydreringen genom att den 5 bringas i kontakt med en gas eller gasblandning, vars vattenangtryck är lägre än arbetslösningens vattenangtryck.
2. Förfarande enligt krav 1, kännetecknat av att som gas eller gasblandning används luft eller en eller flera av de gaser 10 som ingar i ren luft.
3. Förfarande enligt krav 1 eller 2, kännetecknat av att gasblandningen innehäller högst 8 vol% syrgas. 15
4. Förfarande enligt ett eller flera av de föreglende kraven, kännetecknat av att gasblandningen innehäller minst 97 vol% kvävgas eller koldioxidgas.
5. Förfarande enligt krav 1, kännetecknat av att som 20 gas eller gasblandning används avgas frän antrakinonprocessens oxi- deringssteg.
6. Förfarande enligt ett eller flera av de föregäende kraven, kännetecknat av att arbetslösningen torkas tili en rela- 25 tivt fukthalt av 20-98%, företrädesvis 40-85%.
7. Förfarande enligt ett eller flera av de föregäende kraven, kännetecknat av att torkningen genomföres vid en tempe-ratur av 25-90°C, företrädesvis 35-70°C. 30
