Data on the impurity content in hydrocarbon feedstock of ethylene plant EP-300 are cited. The distribution of impurities and their transformation products in gaseous and liquid pyrolysis products and in dilution steam condensate is investigated. The influence of impurity transformation products on the aqua-chemical condition of the dilution steam generation unit is studied. Recommendations are offered for reducing impurity content in pyrolysis feedstock.
