Outline and Purpose of the Course Chemical processes are comprised of a combination of various operations (unit operations), and this course will discuss distillation, gas-absorption, and other fluid-based mass transfer unit operations for separating and purifying substances, as well as mechanical unit operations related to the production and processing of particulate matter (powders), beginning from an overview of their basic phenomena and operating principles together with the study of the related kinetic phenomena and their quantitative expression methods. Students will also learn methods for the safe operation and control of chemical processes.
Course Goals Cultivate an understanding of the concepts of mass balance, mass transfer, equilibrium relationship, and control by studying examples of typical separation operations, particle-based separation operations, and process control in chemical processes. In addition, students will develop the ability to quantitatively analyze chemical processes.
Schedule and Contents 1. Basics of substance separation and purification, 2 sessions
These sessions will explain the principles and methods of separation and purification of important substances in chemical processes, as well as the fundamentals of molecular diffusion and mass transfer.

2. Gas absorption, 2 sessions
Students will learn the concept of the “differential contact method”, through lectures discussing equilibrium of gas dissolution in liquids, the diffusion phenomenon in the liquid phase, gas absorption rates, and design methods for gas absorption devices.

3. Distillation, 3 sessions
These sessions will describe the correlation method of vapor-liquid equilibria, explain the basic principles of various distillation operation methods for mixed liquid purification procedures, and explain the design method for a continuous rectification stage column, which is the simplest “multi-stage contact operation.”

4. Overview of particle system operation, 2 sessions
These sessions will describe the role of particle-based unit operations in chemical processes, the evaluation of particle characteristics, their methods of expression, and the behavior of particles.

5. Gas-solid separation, 2 sessions
These sessions will describe the concept of partial separation efficiency, in addition to discussion of the principle of solid-gas separation and the methods for evaluating separation performance applicable under various conditions.

6. Process control, 3 sessions
These sessions will promote an understanding of the characteristics of systems characterized by dynamic input and parameter values and also briefly describe the control methods for compensating fluctuations by taking distillation column and reactors as examples.

7. Feedback, 1 session
Supplementary classes or exercises are conducted outside of the regular course schedule to confirm the achievement of learning objectives related to diffusion, gas absorption, and distillation.
Evaluation Methods and Policy Course grades will be based on the results of regular examinations and reports assigned as needed to improve understanding.
Course Requirements Introduction to Industrial Chemistry (stoichiometry for chemical engineering), Foundations of Chemical Process Engineering
Study outside of Class (preparation and review) Lectures will be conducted mainly using textbooks, and exercises will be assigned based on the pace of the lectures. Students should make efforts to acquire lecture content.
