6、交通等领域具有十分诱人的前景。其中天然气的液化和储存是一项非常关键的技术，并且它已经形成了一个系统的产业链。天然气技术作为世界一门新兴的工业正在飞速发展，目前仍保持着强劲的势头，我们为从事这样一项新兴的行业感到自豪。天然气行业作为一个朝阳产业，有着很大的开发前景，我们作为其中的一份子一定会为它的蓬勃发展进献自己的一份绵薄之力。通过在党校四个多月的培训，让我们在理论方面都有了一定的基础，唯一不足的是缺乏熟练的操作技能。单位为了丰富我们的实践能力，在绿能高科LNG工厂为我们安排了从2012年10月29日至11月23日将近为期一

7、月的实习，并且采用了师傅带徒弟的模式，让我们能更好的融入，学到更多的知识。为期一月的实习生活马上就要开始了，同时我们也会带着高涨的热情投入其中，争取在实习中勤动脑、多动手让自己能得到更大的收获。一、实习单位简介河南中原绿能高科有限责任公司成立于1998年3月，是国内从事LNG、CNG产业化发展技术实力雄厚的高科技企业。2001年公司建成投产了全国第一座商业化营运的LNG工厂，绿能高科LNG工厂地处中原油田开发腹地，位于濮阳市区东南30公里处的文留镇，其境内资源丰富，地理位置优越，交通便利。填补了国内LNG生产技术和产品的空

8、白，其技术属国内首创，达到国际先进水平；建成投产了全国第一座LNG汽车加气站，成功改装了全国首辆LNG——汽油电喷双燃料汽车、LNG——柴油电喷双燃料汽车，填补了国内LNG汽车的发展空白；研制生产出了撬装式L-CNG汽车加气站、撬装式LNG汽化站装置,让远离天然气管网地区的居民、企业实现了用气，解决了无
