Understanding stoichiometry is really important for making chemical processes work better. By figuring out the right amounts of ingredients (reactants) and what they create (products), engineers can improve chemical production.
In chemical reactions, careful calculations help us know the best possible amount of product we can get.
For example, if 2 parts of hydrogen (H) react with 1 part of oxygen (O) to make 2 parts of water (H₂O), we can write this reaction like this:
If we end up with less than what we expected, it means we didn’t use the right amounts of the ingredients or the conditions weren't just right. A good example of this is when making ammonia using the Haber process.
The reaction looks like this:
To get the most ammonia, we need to balance the amounts of ingredients right. If we use too much of one ingredient, it can cost more money.
Getting the right balance with stoichiometry helps us create less waste. In a perfect situation where everything turns into product, waste can be as low as 5-10% of what we started with.
For example, when making ethylene glycol from ethylene oxide, the aim is to have more than 90% of the materials used turn into the final product. When engineers use the right ratios, they can make the process smoother and waste less.
Using the right amounts of ingredients not only helps us make more product but also helps save money. In chemical processes, if we can increase our product yield by just 10%, it can save a big company over a million dollars each year.
Also, when we lower our costs by using the right amounts of ingredients, it boosts profits. For instance, when making a product called methyl methacrylate on a large scale, getting the exact mix of ingredients can save over $100 million a year for companies with multiple locations.
To sum it up, knowing stoichiometry helps engineers pick the best ingredients for chemical processes. It also helps save money and protect the environment by reducing waste and increasing product yield.
