Abstract

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.

First claim

What is claimed is:

1. A method of manufacturing packing that includes a main plate for forming a liquid film constituting a gas-liquid contact surface, the method comprising:
when arranging a rib along a flow direction of the liquid film,
calculating a relationship between a contact angle of the liquid film on a surface of the rib and a liquid film length ratio indicating a ratio of a liquid film length until the liquid film is ruptured to a flow direction length of the main plate, and
determining a design condition of the rib on the basis of a correlation between the contact angle and the liquid film length ratio.

2. The method of manufacturing packing according to claim 1 ,
wherein in the rib, the contact angle is adjusted so that the liquid film length ratio satisfies a predetermined reference value or a flow direction length of the rib is adjusted so that the liquid film is not ruptured.

3. The method of manufacturing packing according to claim 1 , the method further comprising:
determining types of a gas and a liquid which are brought into gas-liquid contact and a condition of the main plate;
calculating a relationship between the contact angle and the liquid film length ratio;
determining an arrangement of the rib;
determining a material and a surface shape of the rib;
determining a 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 with respect to the contact angle is greater than the minimum value of the flow direction length satisfying the strength requirement; and
determining the flow direction length of the rib within a range from the minimum value of the flow direction length satisfying the strength requirement to the liquid film length with respect to the contact angle.
