Abstract

En fremgangsmåte og apparatur knyttet til produksjonen av hydrokarboner er vist. I en utførelsesform inkluderer en apparatur et rørformet element som har en senteråpning innenfor en innvendig del av det rørformete elementet, hvori senteråpningen tillater hydrokarboner å strømme gjennom det rørformete elementet. Dessuten inkluderer det rørformete elementet åpninger mellom senteråpningen og et område utvendig på det rørformete elementet. I tillegg til det rørformete elementet er minst to tilgrensende vaiersegmenter avsatt rundt det rørformete elementet. De minst to tilgrensende vaiersegmentene danner minst to strømningsveier til senteråpningen. Dessuten danner de minst to tilgrensende vaiersegmentene minst to åpninger konfigurert for å forhindre partikler større enn en spesifikk størrelse fra å gå inn i åpningene i det rørformete elementet.
