本公开涉及碳排放技术领域,尤其涉及一种炼化系统产品碳足迹值计算方法及装置、设备及存储介质。
炼化产品的生产环节复杂,涉及装置多,流程复杂,产生产品多,在生产全过程引起碳排放的因素也是多种多样的。例如不同产品、不同装置产生的碳排放也有所不同,所产生的碳足迹同样也具有多样性。尤其是对于庞大的炼化系统,其中多个装置之间互相关联,因此还涉及到碳足迹传递的问题。
目前,计算碳排放的相关技术中,能够采用一些计算方法对全程的碳排放进行简单计算,计算出石化产品在生产过程中的碳排放总量,以及计算出石化装置针对不同产品的碳排放系数;对于生产环节所引起的过程碳排放一般是全部算在某种特定产品中,并且在计算过程中对于石化装置也是单独进行考虑的,并未考虑石化装置之间互相关联。
本申请发明人发现,目前的相关技术,无法将产品在生产过程中所引起的碳排放合理分配到各个产品中,实现炼化产品的碳足迹值的计算。另外,相关技术中,计算炼化产品碳足迹的方法无法细致深入到炼化生产环节,仅将全过程的碳排放进行简化处理,同时将生产环节所引起的过程碳排放全部算入特定产品中,没有考虑其他副产品或其他物料产出对碳排放分配的影响,同时,也没有考虑装置之间的碳足迹传递关系,因此不能准确的确定炼化系统中的碳足迹。
