摘要： Urea is prepared by reacting ammonia and carbon dioxide in an apparatus comprising a vertical condensation and synthesis column and a stripper, to provide a urea synthesis solution comprising urea, unreacted ammonia, unreacted carbon dioxide and water. The urea synthesis solution is transferred from the top of the vertical condensation and synthesis column to the top of a stripper. Carbon dioxide is introduced into the bottom of the stripper and contacted with the urea synthesis solution, thereby separating the unreacted ammonia and the unreacted carbon dioxide from the urea, and providing a mixed gas comprising ammonia, carbon dioxide and water. The mixed gas is transferred into the bottom of the vertical condensation and synthesis column, where it is reacted with liquid ammonia injected into the bottom and a middle of the vertical condensation and synthesis column. The mixed gas and liquid ammonia are condensed and react to form urea, Uncondensed gases are absorbed in an absorbing medium, which is subsequently recycled to the bottom of the vertical condensation and synthesis column.

摘要： This invention provides a hollow fiber membrane module which can reduce pressure loss in discharging water within a module and can reduce operating power. A hollow fiber membrane bundle comprising a plurality of numbers of hollow fiber membranes are disposed within a cylindrical case having in its side face an opening part for the inflow/outflow of water, and the end of the hollow fiber membrane bundle is fixed by bonding at a position which is located in the axial direction of the cylindrical case at an outer position than the position of the opening part for the inflow/outflow of water on the side face of the cylindrical case. The hollow fiber membrane module is characterized in that a distribution cylinder provided with distribution holes is provided inward with respect to the opening part for the inflow/outflow of water on the side face of the cylindrical case and so as to surround the outer periphery of the hollow fiber membrane bundle, and grooves and/or corrugated protrusions are provided on the inner face of the distribution cylinder so as to be in communication with each other among the distribution holes.
