Title:
METHOD FOR ANALYZING CONDENSATION RATE IN METAL VAPOR
Document Type and Number:
Japanese Patent JP2004294116
Kind Code:
A
Abstract:

To reduce labor and costs for predicting condensation rate by precisely predicting the condensation rate when cooling vapor in metal zinc, or the like, for collecting as liquid zinc.

The method for analyzing metal condensation rate when cooling metal vapor while the metal vapor is circulated in a reaction pipe along with an atmospheric gas for condensing the corresponding metal comprises a process for setting initial conditions (a); a process for indicating the amount of change in atmospheric gas flow rate, the molar fraction of metal vapor, and the molar fraction of the atmospheric gas before and after a minute section (ΔL) in the reaction pipe by an ordinary differential equation (b); a process for solving the ordinary differential equation for calculating the amount of condensed metal and the amount of metal oxide generated in the minute section (c); and a process for calculating the metal condensation rate from them (d). The condensation rate can be precisely predicted without any experiments and without manufacturing an actual apparatus.
