Description

Dr Seijer Troost, 'The origin of the Koninklijke Nederlandsche Zoutindustrie (KNZ) and the growth of this salt producer until 1939'

Zaankanter Jacob Vis developed a new process to extract salt from brine via vacuum evaporation. He built the first plant with this process in 1893 at Kralingsche Veer in Rotterdam. Due to the discovery of extractable quantities of rock salt in the eastern Netherlands and the political situation of the Netherlands during World War I, he succeeded in founding KNZ with the company based in Boekelo. His successor, Ir.Geurt de Haas, improved the process and built an entirely new factory in Hengelo on the Twente Canal in 1937. This is still today the site of Akzo Nobel's largest vacuum salt plant.

Dr. Ir. Thijs de Groot, "The chlor-alkali industry: where are we now and how did we get there?"

As early as 1800, Cruikshank was making chlorine by the electrolysis of a salt solution. However, the process could not be applied on a large scale at that time because a number of inventions in the field of electricity had yet to be made. Today, the chlorine process accounts for a global production of over 50,000,000 tonnes per year and the electricity consumption of the process is over 2,400 kWh per tonne of chlorine. This presentation will tell what developments have taken place in the meantime
