摘　　要：基于LNG接收站耗能设备种类和能源消耗占比的分析,针对国内没有适合LNG接收站的节能定额指标和方法、影响能源管理部门进行节能量下达和下一步考核的现状,选择耗电量、耗气量定额指标代表LNG接收站能耗指标。基于不同的气化方式影响能耗,建立了分地域、分季节、分气化处理台阶来综合制定耗能指标的思路。选择南方和北方各一座典型站场分别来制定耗能定额,使用某时间段内的能耗预测值与能耗实际值作比较,验证能耗指标的适用性和匹配度。对比结果显示,年度能耗预测值与年度实际值相差很小,均在2%以内,预测准确且满足误差要求,目前已经应用在中石油下属多家LNG接收站的节能量指标下达和考核工作中。LNG接收站能耗指标的合理制定,填补了国内LNG接收站节能指标的空白,支持了能源管理部门的节能考核工作,使考核更有针对性、精细化管理水平大幅提高,也使LNG接收站执行起来更加准确,将产生更大的节能效果。In view of the current situation that there is no energy saving quota index and method suitable for LNG terminal in China,which affects the energy saving distribution and the next assessment of energy management department,based on the analysis of the types of energy consuming equipment and the proportion of energy consumption in LNG terminal,the quota index of power consumption and gas consumption is chosen to represent the energy consumption index of LNG terminal.Based on the influence of different gasification methods on energy consumption,the idea of formulating energy consumption index by region,season and stage of gasification treatment was established.A typical station in the south and a typical station in the north were selected to formulate the energy consumption quota,and then the predicted value of energy consumption in a certain period of time was compared with the actual value of energy consumption to verify the applicability and matching degree of energy consumption index.The comparison results show that the difference between the predicted annual energy consumption value and the actual annual energy consumption value is very small,both within 2%.The prediction is accurate and meets the error requirements,which can be used in practice.At present,it has been applied in the energy saving index distribution and assessment work of several LNG receiving stations affiliated to Petrochina.Reasonable formulation of LNG terminal energy consumption index fills the blank of domestic LNG terminal energy saving index,supports the energy conservation assessment of energy management department,makes the assessment more targeted and the level of fine management greatly improved,and also makes the implementation of LNG terminal more accurate,which will produce greater energy saving effect.
