【摘要】：现有的油砂热解装置存在结构较复杂、生产维护成本高等共性问题,本文根据印尼油砂的物化性质对给定的新型油砂裂解炉的结构进行优化设计并搭建小型试验装置以验证其性能。从测试结果上看,该热解装置可以用于进行油砂沥青油和可燃气的生产,且相对简单的系统结构更利于运行维护。本文围绕上述方面进行了如下工作:1)为了获得印尼油砂样品的物化性质,对油砂样品进行了工业分析、热值分析和热重分析并测定了油砂热解产物的组分含量,得出以下结论:印尼油砂的低位热值为9802±58.2 kJ/kg,印尼油砂热加热至470℃左右时主要的热解过程已基本完成,该温度下的产油率和产气率分别为12.07%和3.45%;2)根据油砂的相关特性结合设计目标对给定结构的换热结构进行优化,设计了油砂热解系统中的主要热动装置并协助企业搭建油砂热解小试系统。为了保证系统的运行安全,设计并安装了一套在线监控系统以监控系统的运行状态;3)对搭建完成的油砂热解系统进行冷态调试和热态测试以验证系统的可行性和稳定性,得出以下结论:使用该系统进行油砂热解可以获得燃料油和可燃气等预期产物,热态测试中系统各运行参数基本符合设计值,系统可以用于油砂热解燃料油和可燃气的生产,且测试中有较好的运行稳定性。
[Abstract]:The existing oil sand pyrolysis device has some common problems, such as complex structure, high production and maintenance cost, etc. According to the physical and chemical properties of oil sands in Indonesia, the structure of a new type of oil sand cracking furnace is optimized and a small test device is built to verify its performance. The pyrolysis device can be used for the production of oil sand asphalt oil and fuel gas, and the relatively simple system structure is more convenient for operation and maintenance. In order to obtain the physical and chemical properties of the oil sand samples in Indonesia, the following work has been done in this paper. The industrial analysis, calorimetric analysis and thermogravimetric analysis of the oil sand samples were carried out, and the components of the pyrolysis products of the oil sands were determined. The conclusions are as follows: the low calorific value of oil sands in Indonesia is 9802 卤58.2 KJ / kg, and the main pyrolysis process has been basically completed when the oil sands are heated to about 470 鈩，
