METHOD OF REMOVING CO2 FROM CONTAMINATED HYDROCARBON STREAM

The present invention provides a method to separate CO2 from a contaminated hydrocarbon-containing stream. The method comprises obtaining a multiphase contaminated hydrocarbon-containing stream (100)containing at least a vapour phase, a liquid phase and a solid phase, and creating a slurry stream (120) from the multiphase stream. The slurry stream is fed to a crystallization chamber comprising CO2 seed particles. A liquid hydrocarbon stream (170) is obtained from the crystallization chamber (91) and concentrated slurry (140) is obtained. The concentrated slurry (140) is removed from the crystallization chamber (91) by means of an extruder (142), thereby obtaining solid CO2. A feedback stream (141) is obtained from the solid CO2 comprising CO2 seed particles having an average size greaterthan 100 microns. The feedback stream (141) is passed into the crystallization chamber (91). 本发明提供种从受污染的含烃物料流分离CO2的方法。所述方法包含获得含有至少气相、液相和固相的多相受污染的含烃物料流(100)，从所述多相物料流产生浆料物料流(120)。将所述浆料物料流馈入至包含CO2晶种粒子的结晶室中。从所述结晶室(91)获得液态烃物料流(170)
