	Teaching Methods
	THE COURSE IS TAUGHT IN ITALIAN AND CONSISTS IN FRONT LESSONS (34H), AND CLASSROOM EXERCISES (26H) FOR A TOTAL AMOUNT OF 60 HOURS WHICH ARE WORTH 6 CREDITS. TEACHING INVOLVES LECTURES, INCLUDING THE USE OF MULTIMEDIA DEVICES FOR DISPLAYING CURRENT TECHNOLOGICAL SOLUTIONS, AND CLASSROOM PRACTICE. THE LECTURES PROVIDE THE THEORETICAL CONCEPTS AT THE BASIS OF THE TOPICS DISCUSSED. CLASSROOM PRACTICE HAS THE MAIN PURPOSE OF PUTTING IN PLACE CALCULATIONS FOR EQUIPMENT DESIGN. ATTENDANCE OF LECTURES IS STRONGLY RECOMMENDED.

	Verification of learning
	THE EVALUATION OF THE ACHIEVEMENT OF THE EDUCATIONAL OBJECTIVES WILL TAKE PLACE THROUGH A WRITTEN EXAM AND AN ORAL INTERVIEW. THE WRITTEN EXAM, IN WHICH THE CONSULTATION OF SOURCES IS ALLOWED, USUALLY LASTS 3 HOURS. THE TEST CONSISTS OF TWO DESIGN AND / OR VERIFICATION EXERCISES EACH CONSISTING OF A PART A AND A PART B. THE EXERCISES MAY REQUIRE THE USE OF A SPREADSHEET FOR THE SOLUTION. PARTS A CAN BE CARRIED OUT WITH THE APPLICATION OF STANDARD PROCEDURES AND THE CORRECT SOLUTION OF BOTH PARTS A ALLOWS THE ACHIEVEMENT OF SUFFICIENCY. MARKS HIGHER THAN SUFFICIENCY CAN BE ACHIEVED BY CARRYING OUT PARTS B OF THE EXERCISES WHICH, FOR THE SOLUTION, REQUIRE THE CORRECT APPLICATION OF SKILLS RELATED TO ENGINEERING PRACTICE. THE GRADUATION OF THE VOTE BEYOND SUFFICIENCY DEPENDS ON THE DEGREE OF COMPLETENESS OF THE SOLUTIONS PROPOSED FOR PARTS B. WRITTEN MARKS REQUIRE TO BE CONFIRMED BY AN ORAL EXAM, IN WHICH THE FINAL EVALUATION CAN VARY FROM THE WRITTEN EXAM UP TO A MAXIMUM OF 6 POINTS. THE ORAL EXAM LASTS BETWEEN 45 MINUTES AND 1 HOUR AND CONSISTS OF THREE QUESTIONS, ONE ON REACTORS WITH NON-IDEAL FLUID DYNAMICS, ONE ON REACTORS WITH SOLID CATALYSTS AND ONE ON THREE-PHASE REACTORS. REACHING THE MINIMUM THRESHOLD REQUIRES THE STUDENT TO DEMONSTRATE THAT HE IS ABLE TO CORRECTLY WRITE THE MATERIAL BALANCES IN THE VARIOUS REACTOR CONFIGURATIONS. EXCELLENCE IS ACHIEVED WITH A CORRECT WRITING AND WITH THE DEMONSTRATION OF COMPLETE MASTERY OF THE TOPICS DISCUSSED IN THE ORAL EXAM.
