Objectives
Know the main technologies used in industrial production of chemicals. Understand the importance of scientific knowledge for the chemical industry.
Know the main licensors for the chemical industry and also the main aspects related to chemical processes including row material sources, energy production, licensing for production and sales and also economic aspects.
Prerequisites
Basic knowledge in inorganic and organic chemistry
Basic knowledge in unit operations of chemical engineering
Subject matter
For the most significant chemicals the following aspects are be considered:
- Raw materials
- Chemical reactions and separation processes
- Block diagram of the process according to the indication of the main licensors, where available.
- Differences to alternative processes,
- Recycling of raw materials, recovery of by-products, energy recovery,
- Conversion rates,
-Catalysts and catalysts recycling ,
- Consumption of utilities. Investment value.
- Product applications
- Reference to production units in Portugal
- Typical production capacities
- Investment value and production costs

Teaching method
Theoretical classes, problem resolution classes. Visit to industrial plants. Seminars.
Evaluation method
The studentas are evluated after assessmen to two tests and need to present a seminar(team)
The students have to visit a refining and petrochemical compex and write a report .
Evaluation
- 2 tests, a seminar, visits reports
- the final grade is = 0,6 tests grade +0,2 seminar grade+0.2reports grade
The grade of the first text will be 9.
