The Ostwald process is a chemical process used for making nitric acid (HNO 3). [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. [2] Historically and practically, the Ostwald process is closely associated with the Haber process, which ...
The Birkeland–Eyde process was one of the competing industrial processes in the beginning of nitrogen-based fertilizer production. It is a multi-step nitrogen fixation reaction that uses electrical arcs to react atmospheric nitrogen (N 2) with oxygen (O 2), ultimately producing nitric acid (HNO 3) with water. [1]
Nitric acid is an inorganic ... There will flow down by reason of the heat an oil like cow's butter. ... Johann Rudolf Glauber devised a process to obtain nitric acid ...
Because the syngas was essentially free of impurities, two axial-flow ammonia converters were used. In early 2000 Uhde developed a process that enabled plant capacities of 3300 mtpd and more. The key innovation was a single-flow synthesis loop at medium pressure in series with a conventional high-pressure synthesis loop. [26]
The term PUREX raffinate describes the mixture of metals in nitric acid which are left behind when the uranium and plutonium have been removed by the PUREX process from a nuclear fuel dissolution liquor. This mixture is often known as high level nuclear waste. Two PUREX raffinates exist.
A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
It is a reactant in the atmosphere, where it acts as an aerosol, decreasing air quality and clinging to water droplets, eventually resulting in nitric acid (H NO 3) that produces acid rain. Atmospheric ammonia and nitric acid also damage respiratory systems. The very high temperature of lightning naturally produces small amounts of NO x, NH 3 ...
Nital is a critical plot element in the Japanese manga series Dr. Stone, whose story revolves around the mysterious petrification of all mankind. Made from nitric acid that they produce from bat guano found in a cave, they produce nitric acid by using the Ostwald process (using Platinum as a catalyst and urine as an ingredient) and highly distilled alcohol with a ratio of 3:7.
