Ostwald process pdf. Following figure shows the HYSYS flow diagram of this process. [2] The Ostwald process has gained popularity over the years as it is the easiest way to produce nitric acid, which is also widely used in many areas, such as in the production of fertilisers as well as inorganic and organic nitrates or nitro compounds. Usually, in the Ostwald process, ammonia is transformed into nitric acid. Here is a detailed explanation of the steps involved in the Ostwald process: Steps in the Ostwald Process 1. Particle Coarsening: a process also called Ostwald ripening Ostwald ripening is an observed phenomenon in solid (or liquid) solutions which describes the evolution of an inhomogenous structure over time. The phenomenon was first described by Wilhelm Ostwald in 1896. When a phase precipitates out of a solid, energetic factors will cause large precipitates to grow, drawing material from the Nov 1, 2015 · Simplified block diagram of Ostwald process for nitric acid production. The Ostwald process is a chemical process used for making nitric acid (HNO 3). The process involves the catalytic oxidation of ammonia (NH₃) to produce nitric acid. The process was developed by the German chemist Wilhelm Ostwald in 1901 and is still widely used today due to its efficiency and economic viability. [1] The Ostwald process is a mainstay of the modern chemical industry, and it provides the main raw material for the most common type of fertilizer production.
