1. yellow to dark-colored crude paraffin wax that is separated from part of the oil in paraffin distillate by chilling and pressing or by use of a solvent and that contains considerable residual oil — compare scale wax
After using dewaxing aid, the filtration rate and the dewaxed oil yield were improved, the oil content in slack wax was decreased, and the dewaxed oil changed little in solidification point.
使用脱蜡助剂后,过滤速度、去蜡油收率提高,蜡膏含油量降低,去蜡油凝点变化不大。
The effects of the solvent ratio, the dilution solvent ratio and deoiling temperature on the slack wax deoiling were examined.
分别对溶剂比、稀释溶剂比和脱油温度进行了考察。
The paper introduced the process for low-melting of semi-refined wax made with slack wax from by-product in butanone-toluene dewaxing unit.
