摘要:
A method of manufacturing packing includes: a main condition determination step (Step 1) of determining types of a gas and a liquid which are brought into gas-liquid contact and a main plate (11) to be used; a numerical analysis step (Step 2) of calculating a relationship between a contact angle (¸s) and a liquid film length ratio (Lw/Lt); a rib arrangement determination step (Step 3) of determining the arrangement (intervals) of a rib (12); a rib condition determination step (Step 4) of determining rib conditions; a rib property determination step (Step 5) of calculating the minimum value (Lrmin) of the flow direction length of the rib (12) satisfying the contact angle (¸s) and a strength requirement; a minimum value condition confirmation step (Step 6) of confirming whether or not a liquid film length (Lw (¸s)) is greater than the minimum value (Lrmin) ; and a rib length determination step (Step 7) of determining the flow direction length (Lr) of the rib (12) within a range from the minimum value (Lrmin) to the liquid film length (Lw (¸)).
