Abstract

Raffineringskolonne for metanol og fremgangsmåte hvor det anvendes en mellomliggende gjenkoker. Anvendelse av den mellomliggende gjenkoker reduserer energibe-hovene for metanolproduksjonen. En side-strcm ved eller nær et uttakspunkt for fuselolje oppvarmes i en mellomliggende gjenkoker ved hjelp av et oppvarmingsme-dium med lav temperatur (i forhold til en gjenkoker for bunnprodukter), og fores tilbake til kolonnen ved eller nær fuselolje-uttaksplaten. Uttaksplaten drives ved 85-110C, og 70-90% av gjenkokingsarbeidet tilfares gjennom den mellomliggende gjenkoker. Det gjenværende varmebehov tilføres ved hjelp av en bunnprodukt-vanndampgjen-koker.
