Fractionation of Waste Nitrile Butadiene Rubber (NBR) Latex Sludge

摘要

NBR is one of the common rubber used in oil and gas sector, automotive sector and gloves manufacturing. Conversion of solid waste Nitrile Butadiene Rubber (NBR) latex sludge into liquid can be done by using fractional distillation method. The solid waste NBR was heat above its decompose temperature to evaporate the polymer in form of vapor and will be condensed by condenser column into liquid form. The decomposed temperature of waste NBR was determined by Thermogravimetric (TGA) analyzer which is at 450 °C. The processed hydrocarbon liquid was characterized by using Carbon Nitrogen Sulphur (CNS) analyzer, and Gas Chromatography Mass Spectroscopy (GCMS) analyzer. Sulfur is the main compound exist in the waste NBR latex sludge which is 0.73670 % as it being added for vulcanization process. The carbon and nitrogen percentage are 0.17419 % and 0.16479 %.
