Quantities and Units in Chemical and Environmental Engineering

The International System of Quantities (ISQ) shall be used in education and textbooks, scientific engineering journals, conference papers proceedings, industry, among others. names quantities together with their symbols units are being published by the Organization for Standardization, standard ISO 80000 units, composed 13 parts. Mathematics natural sciences (physics, light radiation, acoustics, physical chemistry, atomic nuclear physics, condensed matter physics) compose most In addition, some disciplines (mechanics, thermodynamics, electromagnetism) characteristic numbers covered. based on Units (SI). Unfortunately, chemical process engineering, as well environmental economics, not dealt standard. this paper, they proposed an additional part a tentative name Chemical engineering. is suggested to include (a) reaction separation mass transfer kinetics, (b) design, control, optimization, (c) mathematical modeling, operational research, (d) climate change, pollution abatement, increase resource efficiency, zero waste circular economy. number planned but limited about 70, average Each quantity item contains definition (including equation if suitable), SI unit, remarks (running will added later). rules defined 80000-1 General rules, practice other parts respected; already included repeated. IUPAC (International Union Pure Applied Chemistry) Green Book respected. literature traditional encyclopedias, handbooks from fields. Some common mistakes printing mentioned.
