lng儲罐都有(you)哪些分類(lei)，大家都知道(dao)嗎(ma)？下面來(lai)一起了解一下吧！

　　1、單容(rong)(rong)罐(guan)：單容(rong)(rong)罐(guan)是LNG儲(chu)罐(guan)剛開始使(shi)用(yong)(yong)的(de)(de)形(xing)式，單容(rong)(rong)罐(guan)罐(guan)內(nei)壁材(cai)料采用(yong)(yong)9%鎳鋼，外(wai)壁材(cai)料為碳鋼，外(wai)壁主(zhu)要用(yong)(yong)于(yu)(yu)隔熱層(ceng)的(de)(de)穩固和保護，以及約束吹掃蒸汽的(de)(de)壓力，不能用(yong)(yong)于(yu)(yu)儲(chu)存從內(nei)罐(guan)泄漏的(de)(de)LNG。內(nei)外(wai)壁之間(jian)填(tian)充保溫(wen)材(cai)料。在金屬罐(guan)外(wai)設(she)有(you)混(hun)凝土圍(wei)堰，用(yong)(yong)于(yu)(yu)防止主(zhu)容(rong)(rong)器發(fa)生事故(gu)時LNG泄漏。單容(rong)(rong)罐(guan)建(jian)造所需成本低，所需時間(jian)也較短，但安全性(xing)也低容(rong)(rong)易泄漏，由于(yu)(yu)安全性(xing)的(de)(de)原因近年來已很少使(shi)用(yong)(yong)了。

　　2、雙(shuang)容(rong)(rong)(rong)罐(guan)(guan)(guan)(guan)(guan)(guan)：雙(shuang)容(rong)(rong)(rong)罐(guan)(guan)(guan)(guan)(guan)(guan)的(de)內罐(guan)(guan)(guan)(guan)(guan)(guan)和(he)(he)外罐(guan)(guan)(guan)(guan)(guan)(guan)均(jun)能獨立儲存(cun)LNG。內罐(guan)(guan)(guan)(guan)(guan)(guan)材料為(wei)9%鎳鋼，外罐(guan)(guan)(guan)(guan)(guan)(guan)材料為(wei)9%鎳鋼或預應力(li)混凝土(tu)，內外壁之間填(tian)充保(bao)溫材料。但(dan)是外罐(guan)(guan)(guan)(guan)(guan)(guan)罐(guan)(guan)(guan)(guan)(guan)(guan)頂是不封閉的(de)，雙(shuang)容(rong)(rong)(rong)式儲罐(guan)(guan)(guan)(guan)(guan)(guan)是在內罐(guan)(guan)(guan)(guan)(guan)(guan)外圍(wei)設置了(le)一(yi)層高度與內罐(guan)(guan)(guan)(guan)(guan)(guan)罐(guan)(guan)(guan)(guan)(guan)(guan)壁相同(tong)，但(dan)與內罐(guan)(guan)(guan)(guan)(guan)(guan)分開(kai)的(de)圓(yuan)柱形(xing)混凝土(tu)防護(hu)墻。雙(shuang)容(rong)(rong)(rong)罐(guan)(guan)(guan)(guan)(guan)(guan)在一(yi)定程度上提高了(le)主容(rong)(rong)(rong)器發生事故時(shi)LNG泄漏(lou)時(shi)的(de)安全性(xing)。但(dan)雙(shuang)容(rong)(rong)(rong)罐(guan)(guan)(guan)(guan)(guan)(guan)與單(dan)容(rong)(rong)(rong)罐(guan)(guan)(guan)(guan)(guan)(guan)相比造價(jia)高、施工周期(qi)長。但(dan)與單(dan)容(rong)(rong)(rong)罐(guan)(guan)(guan)(guan)(guan)(guan)相比，雙(shuang)容(rong)(rong)(rong)罐(guan)(guan)(guan)(guan)(guan)(guan)的(de)建造成本和(he)(he)建造時(shi)間的(de)增加并沒有解決操作壓(ya)力(li)低(di)帶來(lai)的(de)問題，由于這些因素(su)，雙(shuang)容(rong)(rong)(rong)罐(guan)(guan)(guan)(guan)(guan)(guan)近年(nian)來(lai)也很少使用了(le)。

　　3、全容(rong)罐：罐子(zi)由(you)主容(rong)器和(he)次容(rong)器組(zu)成，既(ji)能(neng)低溫儲存LNG，又能(neng)限制并儲存泄露的LNG，不需要設(she)防火堤，安全性能(neng)高(gao)，場(chang)區(qu)布(bu)局緊(jin)湊。但建造周(zhou)期需要三年左右，投(tou)資費用很高(gao)。
