This document is a report submitted by 4 students on gas-liquid chemical reactions. It includes an introduction to gas-liquid reactions and their applications. The report then outlines the various frameworks and canvases used to analyze the system, including mind mapping, AEIOU summary, empathy mapping, ideation canvas, and product development canvas. For each framework, key elements are identified such as environment, interactions, activities, users, problems, and potential solutions. The document aims to understand gas-liquid processes and identify opportunities for improvement.

1. INTRODUCTION
Gas-liquid reactions, it’s one the most important heterogeneous reactions. when it comes to
gas-liquid reactions, there are two broad application areas where these reactions are used.
One is the gas purification processes and these are important not only from the environmental
point of view, but quite often when we want to use certain gases for reactions and we do not
want any impurities associated with it. We have a gas purification process as a most important
part of any reactor system.
We have things like carbon dioxide removal from synthesis gas. for example, using aqueous
solution of hot ammonia and hot potassium carbonate or ethanoamines we can scrub the CO2
gas. So, CO2 removal essentially is useful with the synthesis gas or with the thermal power
plant flue gases.
The idea is that we want to remove CO2 in hot potassium carbonate or ethanolamine. Now,
why hot why potassium carbonate? Because the carbon dioxide will react with it very easily
in suitable conditions.
Then another common polluting agent is sulphur. So, we want to remove it in hydrogen
sulphide or by sodium hydroxide or reacting ethanolamines and so on. So, there are broad
classes of reactions, we can say that these reactions are more of a purification step than any
production step.
The production processes where gas-liquid reaction occur, on the other hand as a target
product. For example, air oxidation of aldehydes to acids or oxidation of cyclohexane to atopic
acid, which is an important monomer. Chlorination of benzene formation of or production of
nitric acid, sulphuric acid and so on. Where product namely acids or chlorobenzenes or
sulphuric acid, these are important products which we want to manufacture using gas-liquid
reactions.

2.Mind Mapping
The image of mind mapping is given below

3.AEIOU SUMMARY
First, we started working in AEIOU summary.
• A: Activities
• E: Environment
• I: Interactions
• O: Objects
• U: Users
This canvas is totally based on the observations. Activities as the name suggests we have
to describe all the activities we observed like if we are in chemical plant we have seen
like…
The image of AEIOU summary is Given below.

8. 8
3.1) Environment:
• It can be noisy due to certain operations
are going on simultaneously.
• Here if we are working in the chemical
industry, obviously, there will be Chemical
smell.
• Apart of the equipment’s in which
gas-liquids are going on there is another
processes are also going on with it so all
the processes are considered as the process
industrial environment.
• There are no. of employee are working in
the industry around and industry, so work
environment of workers can be seen around.
3.2) Interactions:
• there are interactions between engineers and
worker outside the reaction system.
Workers like ITI, technicians etc.
• other interactions are between worker to
their helpers
• HR-department to all employees of company
for improvement of the production, financial
states and for other matters.
• Industrial meetings: it’s one of the most
way in industry for the interaction.
 Other important interaction is between
employee with supplier and buyers of the
company.

9. 9
3.3) Objects:
We have to describe observed object and
user to correspondingly object frame and
user framework. In our case, there is
chemical plant, so objects are
• LAB
• Equipment
• Flow-charts
• Power supply
• Safety instruments
3.4) Activities:
In this section, we have to mention the
things happening around the system
• Raw material to procedure
• Research and Development
• maintenance
 Employer’s work
 Mass transfer operations (industrial)
3.5) Users:
The main user of gas-liquid industries
are given below
• Customer
• Other industries
• Chemist
 Pollution control department

4.EMPATHY MAPPING

11. 11
Basically, there are four sections in Empathy Canvas,
1. User
2. Stakeholders
3. Activities
4. Story Boarding
To fill empathy canvas, we have studied problems related gas-liquid industries and the people
affected with it, their activities and experience.
4.1) User
• Customer
• Other industries
• Chemist
 Pollution control department
4.2) Stakeholders:
Due to Gas-liquid operation, people
that would be indirectly affected are
• Customer
• Engineer
• Workers
 Helper
 H.R. Department
4.3) Activities:
The activities carried out by stakeholders are

12. 12
4.4) Story Boarding
• There are two happy experience and two sad experience which are given below: first happy
experience is about the how the gas-liquid operation is useful for purification purpose and
second experience is about the product, which can be useful the other industries.
 There are two bad experience also, which is related to hazards and another story is about the
not complete removal of some material.

5. IDEATION CANVAS
• Ideation Canvas contain main four sections
1. People
2. Activities
3. Situation/Context/Location
4. Possible Solution
• If we talk about Ideation Canvas then it is something near to our main problem which we want
to find. In people part, only those people mention which is only related to our problem only.
• In Activities means during which you are facing problem. In location/Situation means in
which situation and location problem become in picture that things must be maintained.
• The thought for context/location/situation and finally for possible solutions is at last we have
to find problem and that can be possible solution and way that things can be mentioned.
