The invention concerns a method and a device for removal of malodorous compounds which arc formed during asphalt production. The method according to the invention is characterised in that the gases arc first cleaned out of dust and small solid particles and subsequently they are sent to a low-temperature plasma generator, where their decomposition takes place. The device according to the invention is composed of a cylindrical dielectric casing (5) centred by dielectric rings (1), In the casing there is a high-voltage mesh electrode (3) and a passive mesh electrode (6), both cylinder-shaped and of the same length and mesh size. They are placed inside and outside of a cylindrical dielectric (2), preferably of small thickness.
