【摘要】：石化企業(yè)儲罐無組織排放揮發(fā)性有機(jī)物(VOCs)帶來嚴(yán)重的環(huán)境問題和油品損耗問題,以浮頂罐的大呼吸損耗為代表。在概述浮頂罐大呼吸損耗機(jī)理的基礎(chǔ)上,以北京某石化企業(yè)的甲苯內(nèi)浮頂罐為基準(zhǔn)案例,對國內(nèi)外4種核算公式進(jìn)行了對比分析,考察了影響浮頂罐大呼吸損耗的因素,并提出有效的減耗措施。結(jié)果表明:采用我國推薦的公式進(jìn)行核算更符合我國實(shí)際,需建立和完善以我國有機(jī)液體理化參數(shù)和儲罐構(gòu)造為基準(zhǔn)的核算方法和軟件;影響浮頂罐大呼吸損耗的主要因素包括油品性質(zhì)、周轉(zhuǎn)量、罐體直徑、罐壁黏附系數(shù)等,其中罐壁黏附系數(shù)為關(guān)鍵影響因素。
[Abstract]:Volatile organic compounds (VOCs) emissions from storage tanks in petrochemical enterprises bring serious environmental problems and oil loss problems, represented by the large breathing loss of floating roof tanks. On the basis of summarizing the mechanism of large respiration loss of floating roof tank, taking the toluene inner floating roof tank in a petrochemical enterprise in Beijing as a reference case, the paper makes a comparative analysis of four kinds of accounting formulas at home and abroad, and investigates the factors affecting the large breath loss of floating roof tank. And put forward effective measures to reduce consumption. The results show that the calculation method and software based on the physical and chemical parameters of organic liquids and the structure of storage tanks should be established and perfected. The main factors affecting the large respiration loss of floating roof tank include oil properties, turnover, tank diameter and wall adhesion coefficient, among which the adhesion coefficient of tank wall is the key factor.
