Each step in the process contributes to the overall outcome and desired product. The concept of "unit operations" has been present in the chemical engineering profession since George Davis organized his original 12 lectures around it. Arthur Little was the first to recognize the potential of using "unit operations" to differentiate chemical engineering from other professions. Examples of unit operations include distillation, drying, evaporation, crystallization, extraction, petroleum refining, food processing, salt production, sugar and pharmaceutical production, and oil extraction from seeds.

Chemical engineers were the first to concentrate on the shared processes of all chemical products, reactions, and machinery. Meanwhile, mechanical engineers focused solely on machinery, industrial chemists centered their attention on products, and applied chemists devoted themselves to individual reactions. The conceptual tool known as unit operations enabled chemical engineers to establish their distinctiveness and value within the chemical manufacturing industry.

In order to produce sulfuric acid using the Lead-Chamber Method, a technique that had been long employed but not well comprehended, various ingredients were required: air, water, sulfur dioxide, nitrate, and a large container. Out of these components, nitrate was often considered the most costly due to its need for replenishment since it was released into the atmosphere as nitric oxide during the final stage of the process.

Due to its significance, sulphuric acid was viewed as a reliable gauge of a nation's industrial prosperity. In the pre-World War I

era, two German patriots invented a technique to produce synthetic ammonia. Shortly after the war commenced, the initial plants employing this "Huber-Busch Process" were built. These individuals had found that ammonia could be produced by combining nitrogen gas and hydrogen gas in a chamber with high pressure.

By adding a catalyst and applying heat to accelerate the process, large amounts of fixed nitrogen can be generated. Another competitive industry, called Alkali & The El Blanch Process, produced soda ash (Nuance) and potash (KICKS) through ancient manufacturing methods. These Alkali compounds were extensively used in various products such as glass, soap, and textiles, and were highly sought after.
