Abstract
A vertical catalytic ammonia converter whose recipient includes an outer shell and a dual duct tubular inner wall to route effluents upwards and downwards, said tubular wall comprising numerous tubular elements arranged in a circle on the outer periphery of the inner wall of the outer shell, said elements comprising gastight tubes that carry the effluent upwards, and contiguous to which are filtering media over the entire height of the catalyst bed, the filtering media being closed at the lower end to carry an effluent downwards and distribute it in said catalyst bed the outer face of which is retained by said filtering media.
Claims17
Vertical ammonia converter with radial flow catalyst beds, comprising a recipient consisting of an outer shell equipped with a dual duct inner tubular wall to route effluents in the upward and downward directions, said tubular wall being made of a multitude of vertical tubular elements arranged in a circle on the outer periphery of the inner wall of said outer shell, said tubular elements being made of gastight tubes, open at the top and bottom to route an effluent to be treated in the upward direction from an injection chamber located in the lower part of said outer shell to a distribution chamber located in the upper part of said outer shell, which tubes are contiguous to the filtering media over the height of a catalyst bed, the filtering media being open at the upper end to allow the passage of a downward-flowing effluent and closed at their lower end to route and distribute said effluent through their effluent-permeable face towards the catalyst bed retained on its outer face by said filtering media.
Dual duct tubular system to form the inner wall of a recipient of a radial flow catalytic ammonia converter, comprising a plurality of gastight tube sections and filtering media, with each tube section having a side contiguous to a convex-shaped filtering media to form a duct, one end of said filtering media being open, and the other being closed and gastight, with the base of each of said tube sections being preferably fixed to a slot in a flat, with the end of said filtering media in said base being obstructed by the solid part of said flat, each flat being designed such that it is mounted on the outer periphery of a catalyst bed support plate.
