Description

Technical field: [0001] The invention relates to the technical field of solvent oil, in particular to an environment-friendly solvent and a partial monomer alkane production device and a method for using the same. Background technique: [0002] The existing petroleum hydrocarbon solvent production equipment and methods in my country are generally designed according to the source of raw materials and product standards at that time, so there are limited processing raw materials, poor product quality (high volatile organic compound emissions, strong odor), and poor processing flexibility of the equipment And other problems, can no longer meet the development requirements of the current environmental protection solvent. At present, the petroleum hydrocarbon solvent production technologies at home and abroad mainly include extractive distillation, adsorption separation, sulfonation and catalytic hydrogenation, among which catalytic hydrogenation is the most widely used method. Th...
