摘　　要：随着全国碳排放权交易市场的不断发展完善,碳成本对于LNG接收站企业生产运营的影响不容忽视。选取长三角地区拟建加工能力为600×104 t/a的某LNG接收站二期工程项目为例,参照已投产的一期项目历史年度碳排放情况,运用排放因子法测度其运营周期内各年度碳排放时序性发展水平,并考虑未来碳交易市场价格水平对LNG接收站投资回报产生的影响。研究结果表明:该LNG接收站考虑碳排放后,碳成本在经营成本中的占比逐年增大,最高可达4.11%,对LNG接收站经营成本影响显著;若保持8%的全投资内部收益率(税后)不变,LNG加工费增加了0.51%;对未来碳排放价格进行敏感性分析,可知碳排放价格波动对LNG加工费的影响在±0.1%之间。可见,碳成本对LNG接收站的经营成本与加工费具有一定的影响,研究成果可为LNG接收站纳入碳排放成本后评估项目的经济性提供参考。(图4,表8,参24)With the continuous development and improvement of the national carbon emission trading market,the impact of carbon cost on the production and operation of LNG terminal enterprises becomes unignorable.Herein,study was performed based on an LNG terminal phase-II project in Yangtze River Delta with the proposed processing capacity of 600×104 t/a.Specifically,the chronological development level of carbon emissions in each year during its operation cycle was measured with the emission factor method based on the historical annual carbon emissions of the phase-I project that has been put into operation.Meanwhile,consideration was given to the impact of price level in future carbon trading market on the investment return of LNG terminal.The research results show that the proportion of carbon cost with consideration to the carbon emissions of LNG terminal in the operating cost of the LNG terminal increases year by year with the influence of the carbon market price,with the maximum of 4.11%,which has a significant impact on the operating cost of LNG terminal.If the internal rate of return on total investment(after tax)remains at 8.00%,the LNG processing cost will increase by 0.51%.On this basis,sensitivity analysis was conducted for the future carbon emission price,which shows that the impact of carbon emission price fluctuation on LNG processing cost is within±0.1%.Generally,the carbon cost has a certain impact on the operating and processing costs of the LNG terminal,which could provide a reference for the economic evaluation of an LNG terminal project with carbon emission cost considered.
