GAZ-KIMYO MAJMUASI CHIQINDILARINI QAYTA ISHLASHNING TEXNIK-IQTISODIY ASOSLARI: USTYURT GAZ-KIMYO MAJMUASI MISOLIDA
This research analyzes the technical and economic aspects of processing tar waste generated in the polymer production division of the Ustyurt Gas Chemical Complex. The plant, which produces 8,000 tons of product annually, generates 10-12 tons of tar waste per day. Laboratory studies showed that from 2 kg of tar product, 1 liter of boiler fuel and 830 g of carbon material were obtained. The economic calculations indicate that a recycling plant could recoup its investment within 3-4 years. The study also evaluated the optimization of the technological process and the efficiency of the investment.
