“XXXXXL19Dwc”中国首座冷热能XXXXXL19Dwc互换站在天津投产

  中新XXXXXL19Dwc社北京11月13日电 XXXXXL19Dwc(记者 刘亮)记者13日从中国石化获悉,中国石化在天津南港正式投用国内首座冷热能互换站,年处理能力超260万吨,标志着中国石化在冷能综合利用领域取得重大突破。

  中国石化相关负责人介绍,该项目是中国首次实现LNG(液化天然气)接收站与大型石化产品生产装置之间能量耦合,每年可节省天然气1300万立方米、节电300万千瓦时,对进一步促进能源绿色低碳转型具有重要示范意义。

  项目以LNG为冷能,以乙烯生产装置富余热量为热能,清洁能源甲醇为中间介质。生产过程中,乙烯装置需要冷能给设备降温确保安全生产,LNG需要热能将低温的液态天然气加热至气态。传统方式均采XXXXXL19Dwc用耗能设备进行降温和加热,而该项目创新通过甲醇在高低温换热器中进行能量交换,形成冷热能循环,有效降低了能耗、实现绿色生产。

  该互换站突破LNG冷能利用在规模和距离上的双重壁垒,创造了每小时346吨的国内最大冷能利用量,也实现了长达22公里的超远距离冷能输送,彻底改写了中国冷能仅在小范围应用的历史。同时,借助创新研发的冷热互换技术,冷能转换效率超95%,居国内冷能利用率首位,进一步验证了LNG冷能利用的巨大潜力。(完)
