    Abstract: Mechanical separating apparatus for use in hydrogenation plants for coal and heavy oil at pressures of 150 to 700 bar and temperatures of 350 to 500 DEG C with a shell-side inlet connection (6) for the hydrogenated product which comes, for example, from a liquid-phase reactor, having another shell-side connection (9) for the addition of circulating gas, an outlet connection (12) arranged in the lower part of the separating apparatus for the liquid/solid phase, and an outlet connection (11) arranged on top for the gaseous phase, having the following features: a) The pressure vessel (1) is made of low-alloy steel (2.25% Cr, 1% Mo) with a wall thickness of between 100 and 400 mm and an outside diameter of between 1200 and 3000 mm. b) The pressure vessel (1) is surrounded by a concentric cylinder (13) of unalloyed steel having a wall thickness of between 10 and 20 mm, the distance between the pressure vessel (1) and the concentric cylinder (13) being between 40 and 150 mm. c) The hydrogenated product, which enters into the inside of the pressure vessel (1) via the inlet connection (6) is deflected tangentially downward by baffles (7, 8). d) The pressure vessel (1) is closed in its lower part by a cone (4) which passes into the outlet connection (12) for the liquid/solid phase. In the upper part the pressure vessel (1) is closed by a spherical plate (2) and a flat cover (3).
