Method of recovering carbon dioxide from a synthesis gas stream

A method of recovering carbon dioxide from a synthesis gas stream generated within a facility having a synthesis gas reactor, a water-gas shift reactor and a steam generation system for generating steam for the synthesis gas reactor and for export. After the synthesis gas stream is passed through at least one process heat exchanger of the steam generation system located downstream of the water-gas shift reactor, the temperature of the synthesis gas stream is increased while simultaneously adding steam to the synthesis gas stream. Thereafter, the synthesis gas stream is added to an absorption system having an absorption zone utilizing a solvent to absorb the carbon dioxide and a regeneration zone to disengage the carbon dioxide from the solvent and thereby regenerate the solvent. Heat is transferred from the synthesis gas stream to the regeneration zone to promote disengagement of the carbon dioxide from the steam and such that between about 40 percent and about 90 percent of the carbon dioxide originally present in the synthesis gas stream is recovered. The temperature of the synthesis gas stream can be increased and steam can be added thereto by mixing superheated steam with the synthesis gas stream. Alternatively, a synthesis gas stream can be introduced into a saturator utilizing a water stream that undergoes indirect heat exchange with a low pressure steam stream.

Novel rotation type compound vibrating screen

The invention adopts transport motion as round or linear or elliptical vibration mode motion of a screen box, and a screen drum installed on the screen box moves along with the screen box and makes fixed axis relative rotation around the longitudinal axial line of the screen drum. Materials in the screen drum make point spatial compound curvilinear motion. Because the materials in the screen are under the action of multi-directional exciting force in the space, all kinds of different demands on the vibrating screen can be better met. The screen box is installed on a base by a bearing spring, and is excited by an exciting motor to make round or linear or translational elliptical or variable linear or variable elliptical vibration and vibration in other different vibration modes. The screen drum makes relative fixed axis rotation at uniform speed or variable speed or in a set rule around the own axial line by an anti-vibration driving motor. Vibration of the screen box can be designed and determined based on a ''center of force theory of an inertia vibrating screen'' and an ''unequal mass-radius product following self-synchronizing theory'', so that the screen box can make vibration in all kinds of different trace vibration modes. Rotation of the screen drum can be at constant speed or variable speed or in a pulse mode or other set rules.
