FIELD: gas industry.
SUBSTANCE: invention relates to an extrusion system for degassing of a mixture. The extrusion system includes first extruder (1), second extruder (2) located downstream from first extruder (1), and transfer zone (6) formed between them. Moreover, a pressure adjustment device is provided, using which pressure of mixture (5) is adjusted at an outlet of first extruder (1), as well as perforated plate (10), using which mixture (5) passed through transfer zone (6) is divided into several partial streams. At the same time, the transfer zone includes the first part of a pipeline, which is adjacent to the first extruder and has a decreased volumetric cross-section compared to the first extruder, wherein the second extruder has a degassing zone, and pressure in the second extruder, at least in the area of the degassing zone, is maximally lowered relatively to excessive pressure in the transfer zone.
EFFECT: improvement of degassing in an extrusion system.
