摘要： A gas-liquid contact apparatus has a gas-liquid contact unit, a liquid supply system, and a gas supply system. The gas-liquid contact unit includes a plurality of stages which are allocated so as to be arranged in the lateral direction. Each of the plurality of stages includes a plurality of vertical flat plates arranged parallel to each other at intervals. The liquid supply system supplies a liquid to the gas-liquid contact unit, and causes the liquid to be circulated along the arrangement of the plurality of stages successively. The gas supply system supplies a gas to the gas-liquid contact unit, and causes the gas to be circulated along the arrangement of the plurality of stages successively. The supplied liquid flows down on the plurality of vertical flat plates in each of the plurality of stages, and comes into contact with the supplied gas.

摘要： A method of manufacturing packing includes: determining types of a gas and a liquid which are brought into gas-liquid contact and a main plate to be used; calculating a relationship between a contact angle and a liquid film length ratio; determining the arrangement (intervals) of a rib; determining rib conditions; calculating the minimum value of the flow direction length of the rib satisfying the contact angle and a strength requirement; confirming whether or not a liquid film length is greater than the minimum value; and determining the flow direction length of the rib within a range from the minimum value to the liquid film length.

摘要： The gas separation device separates or captures a target gas component from a gas to be processed by: causing an absorbing liquid to flow down on a surface of a packing disposed inside a processing tank while supplying the gas to be processed containing the target gas component into the processing tank; bringing the absorbing liquid flowing down on the surface of the packing and the gas to be processed into gas-liquid contact; and thereby causing the absorbing liquid to absorb the target gas component contained in the gas to be processed. The packing includes at least one packing unit formed from multiple expanded metal plates, which are disposed vertically and arranged in parallel. Each expanded metal plate includes strands forming the openings which are arranged like stairs. Each strand is inclined to the vertical direction at an angle in a range from 48° to 73°.

摘要： A hydrophilized material has a surface provided with surface roughness that arithmetic mean roughness is 0.3 μm to 1.0 μm and mean width of roughness profile elements is 0.1 mm or less. A hydrophilized member that contacts a liquid is at least partially made of the hydrophilized material. The hydrophilized member is applicable to a gas-liquid contact apparatus having a gas-liquid contact section, a liquid supply system, and a gas supply system, to constitute the gas-liquid contact section as a packing element. Wettability imparted due to the surface roughness is exhibited continuously.

摘要： The carbon dioxide recovery method and apparatus are capable of reducing energy for regenerating the absorbing liquid and operating cost. An absorption column has first and second absorbing sections that a gas is supplied through the first absorbing section to the second absorbing section and the absorbing liquid absorbs carbon dioxide. A regeneration column regenerating the absorbing liquid has first and second regenerating sections. The first regenerating section has an external heating implement and the second regenerating section is heated by the gas discharged from the first regeneration section. Circulation mechanism has a circulation system circulating the absorbing liquid between the second absorbing section and the first regenerating section, and a branch path branched from the circulation system. A part of the absorbing liquid circulating the circulation system flows from the second absorbing section through the first absorbing section and the second regenerating section successively to the first regenerating section.
