Abstract

Fremgangsmåte for rensing av utboret borekaksmaterial som innbefatter faststoff, olje og vann, hvor fremgangsmåten innbefatter trinnene å mate det utborede borekaksmaterial (13) inn i et termisk behandlingsapparat (2), og varme opp det utborede borekaksmaterial deri for å frembringe oppvarmet faststoff (26,28) og en strøm (29) med olje, vann og faststoff, å føre det oppvarmede kaks ut fra det termis-ke behandlingsapparat (2), mate strømmen til et avkjølingsapparat (4) for å kjøle nevnte strøm (29), og frembringe en avkjølt strøm (16, 25), kjennetegnet ved at fremgangsmåten videre innbefatter trinnet å mate den avkjølte strøm (16, 20, 25) til en overløpstank (40) og med overløpstanken (40) frembringe en første rengjort strøm med olje (24) og en strøm (17) med uren væske og faststoff. Apparatet for rensing av utboret borekaksmaterial innbefatter et termisk behandlingsapparat (2), et avkjølingsapparat (4) og videre et overløpstankapparat (40).
