| Titanium dioxide has excellent chemical,physical and optical properties,and is widely used in many industries such as: catalyst(or catalyst carrier),titanium dioxide sol inorganic binder,ultraviolet absorber,adsorbent,titanium fiber,photocatalyst type titanium dioxide Wait.In recent years,the application scope of titanium dioxide is still expanding.Titanium dioxide is closely related to the development of many industries,so its consumption has also become one of the indicators to measure people’s living standards.In this paper,the rutile titanium dioxide prepared by the chlorination method is taken as the engineering research object,and the production capacity of the engineering research is calculated at 80,000 tons/year.It mainly studies the domestic and foreign market prospects of titanium dioxide,the selection of product production process plans,and conducts material balance,energy balance and water balance calculations for the entire project,calculation of wall thickness of main equipment,Aspen energy simulation calculation of main equipment,Building structure calculation,product energy analysis and other public works related calculations,product structure characterization,engineering investment estimation and financial risk assessment,etc.Engineering research;General floor plan.The research results of the paper show that: 1.The production of rutile titanium dioxide by the chlorination method meets the current production needs and meets the relevant national industrial policies;2.The production of titanium dioxide by the chlorination method meets the requirements of environmental protection and other aspects at the current stage,and is conducive to improving The industrialization technology level of domestic chlorination titanium dioxide,breaking the monopoly of foreign chlorination titanium dioxide technology in my country,and improving the international status of my country’s titanium dioxide industry;3.According to investment estimation and financial risk assessment,the production of this engineering project is normal After the implementation,the new annual sales revenue can reach1,885,226,400 yuan,the total annual profit of the enterprise can reach 403,363,800 yuan,the investment profit rate is 23.20%,and the internal rate of return on all investment is21.52%(before and after financing).The breakeven point of the project 40.94%;4.Propose the calculation method for the wall thickness of the main equipment in the engineering design,the Aspen energy simulation calculation of the main heat exchange equipment,the material balance calculation of the entire project,the energy balance calculation and the water balance calculation,and the XRD and TEM structure characterization of the product,It provides theoretical support for the engineering implementation of rutile titanium dioxide prepared by chloride method.In short,the engineering device for the preparation of rutile titanium dioxide by chloride method will have very good economic benefits after the project is completed according to the design and implementation of this paper,and the anti-risk ability of the device after completion is also strong.There may be the following difficulties in the process of engineering implementation of this paper: whether the environmental assessment,safety assessment,occupational health pre-assessment and other aspects can be successfully passed;whether the production and construction unit can design and build a more efficient organizational structure as soon as possible,use High-quality team to operate;whether to make strong arrangements for the progress of the device,the planning of funds,and the quality of safety. |
