Continuing education in green chemical processes for aerospace manufacturing: The case of drag-out

In the new era of job market in the EU zone and abroad, novel Occupational Profiles dictate the development and the update of Learning Outcome-based Curricula. This stands for all disciplines and specialties and for various Qualification Levels (QL), from after-school education up to the highest QL. The pertaining Curricula should allude to specific knowledge, skills, and behaviours, that are being mandated from the respective Occupational Profiles. For intermediate QL, namely in between secondary school and University, there is an utmost need for new, updated, attractive Curricula covering current and new market needs. Such Curricula should be supported from Course Units that are technologically updated, thus providing the trainees the skills and knowledge to cover the current and novel Learning Outcomes and Performance Criteria for the specified QL. We herein present a newly developed Course Unit, part of the Green Special Processes course that can be offered in the context of a continuing Vocational Education Training (cVET) Program targeting a QL equivalent to the European QL 5. This Course Unit covers the case of drag-out, which has significant environmental and economic impacts on the engineering of wet chemical processes entailing multiple process baths and requiring rinsing. Such processes are widely used also in Aircraft manufacturing and the related environmental impacts have become very important. Part of the basic theory, as well as part of the practical training are presented herein.
