Embodiments herein relate to a system (200; 300; 400; 500) for obtaining methanol from foul condensate (101) of a pulping process. The system (200; 300; 400; 500) comprises a primary stripper (102) arranged to strip the foul condensate (101) from pollutants, whereby a first methanol-containing condensate is obtained from the polluted stripper off gases (SOGs). The system (200; 300; 400; 500) also comprises a first acidification unit (202) arranged to acidify the first methanol-containing condensate. Further, the system (200; 300; 400; 500) comprises a secondary stripper (204) arranged to strip the acidified first methanol-containing condensate from pollutants to obtain a second methanol-containing condensate, and a distillation column (107) arranged to distil the second methanol-containing condensate from the secondary stripper (204) so as to obtain methanol. Embodiments herein also relate to a method performed in a system (200; 300; 400; 500) for obtaining methanol from foul condensate (101) of a pulping process.
A method performed in a system for obtaining a methanol from a foul condensate of a pulping process, the method comprising:
