An apparatus and a method is described to facilitate separation of hydrocarbons from solid particles (29) being contaminated with hydrocarbons. The apparatus (1) includes a container (3) having a closeable inlet portion (20) for solid particles; a support body (11) in fluid communication with the closeable inlet portion (20), where the support body (11) is arranged to carry the solid particles (29) led in through the inlet portion (20), as the container is connected to an under-pressure generating device (7) to provide an under-pressure in the container (3).
