Lisinopril is an active pharmaceutical ingredient produced through a stepwise chemical synthesis. After purification by means of a low-pressure liquid chromatography it has to be concentrated. For this purpose, the reverse osmosis was tested under various process conditions on a pilot-scale unit. These data were used for capital and operating cost estimation for industrial reverse osmosis unit and evaporator. The validation results of the full-scale unit proves that the decision for reverse osmosis is economically justified and that the scale-up was technically successful.
F.14 Improvements to existing production methods and tools or processes
COBISS.SI-ID: 26568197New (environment friendly) products of high performance and new technologies for a Slovenian painting industry were developed: (i) a water-based polyurethane dispersion, (ii) a water-based acrylic-polyurethane (AC-PU) hybrid emulsion, (iii) a water-based, heavy duty coating for metal surfaces by the use of AC-PU adhesive. Throughout the project work two postgraduate students employed in Helios d.d. obtained a master of science degree.
F.06 Development of a new product
COBISS.SI-ID: 26799877In cooperation with Goodyear Engineered Products Europe the following was succeeded: (i) the required time and energy for products vulcanization was significantly shortened, (ii) the rubber blend was modified and improved, (iii) a testing apparatus for testing automotive timing belt abrasion resistance was developed. The test is a fast-test and gives results in particularly short time. (iv) the mechanical properties and abrasion resistance of automotive timing belt were improved.
