【摘要】：近几十年随着工业的迅速发展,越来越多企业、工厂向大气中排放过量的二氧化碳,引起全球气候变暖、气象紊乱等一系列严重问题,因此温室效应引起了全世界各国的广泛关注。油气集输作为石油工业开采利用不可或缺的重要环节之一,系统效率偏低、能源消耗和碳排放量大,因此研究集输系统二氧化碳排放计算方法,明确其主要影响因素,进而给出合理的减排措施,对于降低集输系统能耗和二氧化碳量具有重要意义。本文以榆树林油田尚十二站转油站为例,结合集输系统工艺流程,对二氧化碳排放量计算的边界条件、集输规模、量化评价的时间段、排碳的营运活动等因素进行了分析,建立了相应的二氧化碳排放计算模型。结合实际生产运行数据,计算分析了该站2010、2011、2012三年的二氧化碳排放量和碳排放构成。结果表明:该站直接排碳量、间接排碳量和其他间接排碳量占总排碳量的比例变化不大,直接排碳量是碳排放的主要来源。在此基础上,对影响碳排放的主要能耗设备——加热炉和机泵的运行效率进行了评价,给出了相应的能耗评价指标和节能技改方案。此外,针对转油站来液温度高的问题进行了分析,以生产运行费用最小为目标建立了掺水运行参数优化数学模型,并给出了序列二次规划的求解方法。综合考虑加热炉改造、机泵改造和掺水运行参数优化三种节能技改方案,预计尚十二站二氧化碳排放可减少0.131 t碳/t油,年总排放量减少2583.28 t/a,减排幅度高达59.5%。
[Abstract]:In recent decades, with the rapid development of industry, more and more enterprises and factories emit excessive carbon dioxide into the atmosphere, causing a series of serious problems such as global warming, weather disorder and so on. Therefore, Greenhouse Effect has attracted worldwide attention. Oil and gas gathering and transportation is one of the indispensable links in the exploitation and utilization of petroleum industry. The system efficiency is on the low side, energy consumption and carbon emissions are large. Therefore, the carbon dioxide emission calculation method of gathering and transportation system is studied, the main influencing factors are clarified, and reasonable emission reduction measures are given. It is of great significance to reduce energy consumption and carbon dioxide content of gathering and transportation system. This paper takes the Yushulin Oilfield as an example to calculate the boundary conditions of carbon dioxide emissions with the combination of gathering and transportation system technological process. The scale of gathering and transportation, the time period of quantitative evaluation, the operation activity of carbon emission and other factors are analyzed, and the corresponding calculation model of carbon dioxide emissions is established. Combined with the actual production operation data, the station 2010 is calculated and analyzed. The results showed that the direct, indirect and other indirect carbon emissions of the station had little change in the total carbon emissions. Direct carbon emission is the main source of carbon emissions. On the basis of this, the operating efficiency of heating furnace and pump, the main energy consumption equipment that affect carbon emissions, is evaluated. The evaluation index of energy consumption and the technical innovation scheme of energy saving are given. In addition, the problem of high temperature in transfer station is analyzed, and the optimal mathematical model of mixing operation parameters is established with the aim of minimum production cost. The solution method of sequential quadratic programming is given. Three kinds of energy saving technical innovation schemes are considered synthetically, such as reformer of heating furnace, modification of machine and pump and optimization of operation parameters of mixing water. It is estimated that 12 stations will reduce carbon dioxide emissions by 0.131t / t oil, and the annual total emissions will be reduced by 2583.28 t / a, with a reduction rate of 59.5 t / a.
