Abstract

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 %.NBR is one of the common rubber used in oil and gas sector, automotive sector and gloves manufacturing.

废丁腈橡胶(NBR)胶乳污泥的分馏

丁腈橡胶是石油和天然气行业、汽车行业和手套制造业中常用的橡胶之一。采用分馏法将固体废丁腈橡胶(NBR)胶乳污泥转化为液体。将固体废丁腈橡胶加热至其分解温度以上，使聚合物以蒸汽形式蒸发，经冷凝塔冷凝成液体。用热重(TGA)分析仪测定了废丁腈橡胶的分解温度为450℃。采用碳氮硫分析仪(CNS)和气相色谱质谱分析仪(GCMS)对加工后的烃类液体进行了表征。硫化过程中添加的硫是废丁腈橡胶胶乳污泥中主要的化合物，含量为0.73670%。碳、氮含量分别为0.17419%和0.16479%。丁腈橡胶是石油和天然气行业、汽车行业和手套制造业中常用的橡胶之一。采用分馏法将固体废丁腈橡胶(NBR)胶乳污泥转化为液体。将固体废丁腈橡胶加热至其分解温度以上，使聚合物以蒸汽形式蒸发，经冷凝塔冷凝成液体。用热重(TGA)分析仪测定了废丁腈橡胶的分解温度为450℃。采用碳氮硫分析仪(CNS)和气相色谱质谱分析仪(GCMS)对加工后的烃类液体进行了表征。硫化过程中添加的硫是废丁腈橡胶胶乳污泥中主要的化合物，含量为0.73670%。碳、氮含量分别为0.17419%和0.16479%。
