Status of Waste Oil Regeneration and Brief Introduction of Its Process Technology _ Recovery
Original Title Status of Waste Oil Regeneration bra tape measure 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 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 Guidance Catalogue of Key Products and Services for Strategic Emerging Industries compiled by the National Development and Reform Commission was officially released in which the recycling of waste mineral oil was listed in the Guidance Catalogue of Key Products and Services for National Strategic Emerging Industries However by 2017 there were 523 enterprises with waste oil recycling and treatment qualification in China and only 1/3 of the waste oil was treated by these compliant enterprises A considerable part of the waste mineral oil was basically treated by non-qualified enterprises and some of them were not properly disposed of but were often treated by negative means such as disorderly disposal arbitrary disposal burning and burying However in China the research on the regeneration process of waste oil was carried out relatively late and the related investment was relatively small Only some special petroleum industries could use advanced technology while most of them were refineries in the form of small workshops with backward technology resulting in very low value of finished products The low price has further limited the development of the industry and the process has not been improved In foreign countries many advanced technologies and processes are becoming mature and have reached the stage of industrial production such as acid-free process distillation-hydrogenation and other processes are becoming the mainstream of waste oil treatment in Western countries However due to the advancement of these technologies the complexity of operation the large one-time investment of regeneration equipment and the need for high-level skilled workers it is difficult to implement a large number of these technologies in China at this stage so finding a better solution has become the key to waste oil treatment in China 1 Current status of waste oil recycling In foreign countries the wiped film distillation regeneration of waste oil started earlier In the 1960s some developed countries in Europe and the United States began to study it and since then they have accumulated valuable experience Until now the western countries are in the leading position in the waste oil recycling industry and even in the whole oil industry The reasons for their success are related to the improvement of policies and government subsidies It can be seen that relevant government policies industry standards and market cooperation are prerequisites for achieving a virtuous circle of waste oil regeneration The 2013-2017 China Waste Oil Market Supply and Demand Analysis and Investment Prospect Research Report released by 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 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 Except for the special field of petroleum the recovery of other industries is quite difficult mainly including the following problems (1) Unclassified recovery mixed oil varieties are complex and the performance indicators of waste oil are different Different types and proportions of waste oil are mixed together which makes the subsequent regeneration treatment more difficult; (2) Transportation is restricted The composition of waste oil is complex containing different pollutants and impurities that may lead to corrosion and scaling of storage tanks so the transportation equipment should be anticorrosive and explosion-proof at the same time However at present the waste oil recovery mechanism seldom has such special equipment; (3) Disposal of violations
