The basic scope of the course is the studying and the performance of fundamental
calculations related to the processing of raw materials, intermediate products and
byproducts which will be used for the production of end-products and energy. The
chemical and metallurgical processes which are taking place within the framework of
mining and metallurgical activities (in the laboratory, in the industry and in the
environment) are directly related to the mass and energy consumption. The
estimation of the mass and energy required for the realization of a physical or
chemical process presents a specific significance as it determines the cost of the raw
and final materials. Therefore, the mass and energy consumption are the most
important indicator for the evaluation of the environmental impact and it is widely
used for the quantification of this impact through the methodology of “life cycle
assessment”. At the same time, the scope of the course is the comprehension of the
combustion theory and the conversion of the chemical energy and the fuels to
thermal energy. Various types of combustion reactors and types of fuels (coal,
petroleum, natural gas, biofuels and “green mixtures”) are studied.
▪ Physicochemical properties and their measurement units
▪ Fundamental principles of the chemical and metallurgical engineering
32
▪ Chemical equations and balance
▪ Chemical reactions. Degree of chemical reaction progress. Degree of reactants
conversation
▪ Raw materials and final products
▪ Physical and chemical processes. Processes flows. Flow sheet diagrams
▪ Fundamental principles of mass balances. Principle of conservation of energy
in open systems. Total mass balance (chemical element and chemical
compound in a system without or with the realization of a chemical reaction)
▪ Methodology for the solving of mass balances Fundamental principles of
energy balances. Basic terms. Energy balance in a closed system. Specific heat
under constant pressure. Enthalpy of chemical reactions. Co-generation of
heat and work
▪ General equation of the energy balance. Energy rate introduced in the system.
Energy rate exit by the system. Energy conversion rate into the system.
▪ Combustion theory, conversion of fuels chemical energy to thermal energy,
type of combustion reactors
▪ Fuels and calorific value (coal, petroleum, natural gas, biofuels and “green
mixtures”)
