Abstract

Keksintö koskee menetelmää ja laitteistoa hydroksikarboksyylihappotuotteen (33) erottamiseksi suspensiosta (31), joka sisältää hydroksikarboksyylihappoa, joka on muodostettu lignoselluloosapohjaisesta raaka-aineesta (2) hydrolyysin (11) ja fermentaation (12) seurauksena. Keksinnön mukaisesti käsitellään suspensio (31), joka sisältää hydroksikarboksyylihappoa, kaksivaiheisen erotuksen (36a-b) avulla hydroksikarboksyylihappotuotteen (33) muodostamiseksi, kaksivaiheinen erotus käsittää ensimmäisen erotusvaiheen (36a), jossa vettä erotetaan suspensiosta, ja toisen erotusvaiheen (36b), jossa hydroksikarboksyylihappotuotetta (33) erotetaan suspensiosta (32), josta vettä on poistettu, ja lisätään hydroksikarboksyylihappoa (39,40) suspensioon (32) ennen toista erotusvaihetta (36b) lisäämään hydroksikarboksyylihapon konsentraatiota toisessa vaiheessa. Lisäksi keksintö koskee hydroksikarboksyylihapon käyttöä konsentroivana aineena.
