Designing Chemical-Injection Systems
Throughout the chemical process industries (CPI), various chemicals must be injected into process streams to serve a variety of purposes. Chemical-injection systems can be arbitrarily defined as those systems that are used to inject chemicals at a flowrate that is less than 1 to 5% of the main process stream. Table 1 shows a non-inclusive list of chemicals that are typically added into process streams via...

Acids Handling
Inorganic acids play a major role in the chemical process industries (CPI). They are used as raw materials, catalysts or finishing and pH control agents in the manufacture of a wide range of chemical products, from fertilizers to detergents, and even foods. Given their widespread use, a major issue in the CPI is the proper and safe handling of the acids, the adequate materials selection for the pieces of...

Focus on Physical Properties To Improve Processes
Music is nature’s gift to humans. Irrespective of nationality, we all like to hum melodies, tap rhythms and sway to pleasing tunes. Even children just learning to stand enjoy wiggling to good music. In all cultures, the notes that comprise musical scales are used in varying sequences and different combinations to compose music. These notes can be thought of as the the physical properties of music...
