The document summarizes a secondary school science project discussing the feasibility of transporting fuel in a gaseous state instead of liquid to cut costs. The student group explores whether this would be more environmentally friendly, how to remove the smell without affecting quality, differences between natural gas and petroleum, potential cost savings, increased capacity, and impact on sales. Through research, the group concludes the suggestion is feasible due to cost and environmental benefits, but removing the smell could impact safety if leaks are not detected.

WHAT ARE THE FACTS I am a chief chemical engineer Due to the harsh economic times and fierce competition from other petroleum companies ,Mr.hoh has been asked to come up with cost cutting measures. My role is to find out if the new manger ,Mr. hoh suggestion of transporting fuel in gaseous state instead of liquid form and also to exclude a chemical substances that gives a special smell to the fuel is feasible.
LEARNING ISSUES Is it more environmentally friendly transport fuel in gaseous state instead of liquid form ? how can you get rid of the smell? What is the difference between natural gas and petroleum? Does it help us save cost? Does it increase the capacity of the fuel if it is transport in gaseous state instead of liquid form ?
LEARNING ISSUES If the smell is remove does it affect the quality Is it more convenient Transporting in what form is better? Will the sales of the company increase? Are there more ways to save cost
ACTION PLAN
Is it more environmentally friendly by transporting fuel in gaseous state instead of liquid form ? :It is more environment friendly. It is largely because of the fact that it has only one carbon and hence, produces less emissions., thereby improving the quality of air.
HOW ? Would we be able to get rid of the smell? :YES o If yes. How can we get rid of the smell? :we could remove the odorants added. which is added to give it the smell.
If the smell is remove does it affect the quality? :it will definitely affect the quality. Natural gas doesn¡¯t have a smell. What you smell is an odorant added by gas companies. Why do they do this? Natural gas has no colour or odour, so it¡¯s extremely hard for you to detect it. Adding an odorant solves the problem. Without the odorant when a gas leak happened it would not be detected easily .And a gas leak might cause death. What can we do to make sure the quality of the fuel is not affected? :do trial and error to make test if the quality is affected if we would to remove the smell.
We can choose to remove or not remove the smell. We should not remove the smell without knowing the effect it will have. The smell is to let people know the presence of the fuel .this to ensure when a gas leak happened people will be alerted.
What is the difference between natural gas and petroleum? :Petroleum have two states of matter and those are 1. Gas(natural gas) 2. Liquid(petrol, diesel etc.)
1)Can it help us save cost when changing from liquid state to gaseous state? 2)What are the ways to save cost? Liquid gas. 1)YES Since when changing from liquid state to gaseous state requires heat energy. we could use a renewable source of energy e.g. heat energy from the sun to change petroleum from liquid state to gaseous state.
Does it increase the capacity of the fuel if it is transport in gaseous state instead of liquid state ? :yes Transporting in what form is better? Liquid or gas :it depends . Will the form being transported affect its quality?
Explanation Liquefied natural gas or LNG is natural gas that has been converted to liquid form for ease of storage or transport. Liquefied natural gas takes up about 1/600th the volume of natural gas in the gaseous state. It is odorless, colorless, non- toxic and non-corrosive. Hazards include flammability, freezing and asphyxia LNG achieves a higher reduction in volume than compressed natural gas (CNG) so that the energy density of LNG is 2.4 times heavier than that of CNG or 60% of that of diesel fuel.[1] This makes LNG cost efficient to transport over long distances where pipelines do not exist. Specially designed cryogenic sea vessels (LNG carriers) or cryogenic road tankers are used for its transport.
Will the sales of the company increase? What can we do to make sure the sales of the company increase? :advertise more before changing into gaseous state and do a market survey before changing into gaseous to see if the people could accept the changes.
Conclusion We can conclude that the new manager suggestion is feasible. And his suggestion should be implemented because there are more pros than cons
Pros Cost effective Eco friendly Convienient odourless
Cons We are unsure that the customers would like the gaseous fuel hence we do not know if it is profitable. When the odorants have been removed and if a gas leak happened ,we may not be able to detect it which maybe dangerous.
