Original Title Status of Waste Oil Regeneration and Brief Introduction of Its Process Technology Total Cumulative Title 1350 The status of waste oil regeneration and brief introduction of its technology Source Guangdong wiped film evaporator Chemical Authors Yu Yanyan Yang Xin Wang Jie Waste oil is a dihedron which has the dual characteristics of pollution and resource improper treatment will cause environmental pollution and recovery and recycling will save energy and alleviate the pressure of resource shortage According to the provisions of the National List of Hazardous Wastes waste mineral oil belongs to hazardous waste numbered HW08 On February 4 2017 the 2016 edition of the Booz Data shows that although China's waste oil products have always existed there has been no effective progress in the effective utilization of waste oil China's waste oil market is large and will grow with the increase of market demand However in China the reasonable recovery rate of waste oil is not high which is mainly affected by the relevant policies and regulations of national and local industries upstream waste oil recovery links downstream regeneration technology and other restrictions Expand the full text Although the state and the oil industry have been promoting the formulation and implementation of policies from the current point of view although policies and regulations have guiding significance they are not enforced there are no severe penalties and certain financial incentives resulting in many difficulties wiped film distillation in operation Due to the vast land area the investment and understanding of waste oil recovery and regeneration vary from place to place and the implementation is different which leads to many difficulties in the recovery process of waste oil regeneration industry
Hydrofining can reduce the loss of effective substances in oil samples improve the yield of regenerated waste oil and will not produce a large number of waste clay and pollute the environment as in the clay refining process so the hydrofinishing process has gradually replaced the clay refining but because hydrofining requires excessive capital investment and operational constraints So that it can no longer be widely used in small and medium-sized enterprises However from the analysis of the current situation of domestic waste oil regeneration the most attractive method for re-refining waste oil can be the combination of solvent extraction and membrane separation and more research efforts should be made to explore the best solvent and solve the problems arising from membrane treatment Return to Sohu to see more Responsible Editor toptiontech.com
