油氣回收中油氣排放的過程

文(wen)章來源:睿馳環(huan)保 人氣:0 發表時間(jian):2022-12-30

  油(you)(you)氣(qi)回(hui)收作為(wei)一種環(huan)保節能(neng)(neng)的裝置,不僅能(neng)(neng)節約資(zi)源(yuan),還可(ke)以保護(hu)生(sheng)態環(huan)境,給人們帶來了(le)很大的好處,下(xia)面,油(you)(you)庫油(you)(you)氣(qi)回(hui)收廠家整(zheng)理了(le)油(you)(you)氣(qi)排放的過程,一起來看(kan)看(kan)吧!

  卸油階段:

  目前,油(you)(you)庫(ku)所儲(chu)油(you)(you)品(pin)的運輸以(yi)(yi)火(huo)車(che)(che)為主,在(zai)卸油(you)(you)過程中(zhong),油(you)(you)氣(qi)(qi)處于負壓狀態,排(pai)放量較小且集中(zhong)。如果要(yao)(yao)使火(huo)車(che)(che)卸油(you)(you)過程中(zhong)油(you)(you)氣(qi)(qi)排(pai)放的瞬時值(zhi)均達到國標規定值(zhi),需要(yao)(yao)對(dui)火(huo)車(che)(che)油(you)(you)罐(guan)的構(gou)造(zao)(zao)進行徹底改(gai)(gai)造(zao)(zao),將其改(gai)(gai)為底部卸油(you)(you);但很顯然改(gai)(gai)造(zao)(zao)工程量大且造(zao)(zao)價高,所以(yi)(yi)難以(yi)(yi)實施(shi)。

  儲油階段:

  該階段的(de)(de)油(you)(you)氣揮發一(yi)般(ban)稱為靜止儲存損(sun)耗或(huo)小呼(hu)吸(xi),主(zhu)要指油(you)(you)品因受外(wai)界環(huan)境如風速(su)、溫度以及濃度的(de)(de)變化而引起的(de)(de)呼(hu)吸(xi)損(sun)耗。針對該階段的(de)(de)油(you)(you)氣排(pai)(pai)放(fang)問題(ti),目前采用的(de)(de)主(zhu)要措施(shi)是增加儲油(you)(you)罐的(de)(de)密(mi)封(feng)性能(neng),將小呼(hu)吸(xi)排(pai)(pai)放(fang)的(de)(de)油(you)(you)氣密(mi)封(feng)在油(you)(you)罐內,防止其排(pai)(pai)放(fang)到大氣中(zhong)。

  收、發油階段:

  相對(dui)于儲油(you)(you)(you)(you)(you)(you)(you)(you)階段,收(shou)(shou)(shou)、發(fa)油(you)(you)(you)(you)(you)(you)(you)(you)階段的(de)(de)油(you)(you)(you)(you)(you)(you)(you)(you)氣(qi)(qi)(qi)(qi)揮發(fa)一(yi)般稱為(wei)大(da)(da)呼(hu)吸,主(zhu)要(yao)指油(you)(you)(you)(you)(you)(you)(you)(you)罐(guan)(guan)(guan)(guan)(guan)從外界(jie)收(shou)(shou)(shou)油(you)(you)(you)(you)(you)(you)(you)(you)和(he)將油(you)(you)(you)(you)(you)(you)(you)(you)罐(guan)(guan)(guan)(guan)(guan)內(nei)(nei)的(de)(de)油(you)(you)(you)(you)(you)(you)(you)(you)品轉移到油(you)(you)(you)(you)(you)(you)(you)(you)罐(guan)(guan)(guan)(guan)(guan)車的(de)(de)過程中,因油(you)(you)(you)(you)(you)(you)(you)(you)罐(guan)(guan)(guan)(guan)(guan)開啟的(de)(de)瞬間和(he)裝(zhuang)(zhuang)油(you)(you)(you)(you)(you)(you)(you)(you)過程中隨著油(you)(you)(you)(you)(you)(you)(you)(you)罐(guan)(guan)(guan)(guan)(guan)或油(you)(you)(you)(you)(you)(you)(you)(you)罐(guan)(guan)(guan)(guan)(guan)車中油(you)(you)(you)(you)(you)(you)(you)(you)品的(de)(de)不(bu)斷(duan)增加(jia),罐(guan)(guan)(guan)(guan)(guan)內(nei)(nei)油(you)(you)(you)(you)(you)(you)(you)(you)氣(qi)(qi)(qi)(qi)因壓(ya)(ya)力升高(gao),呈(cheng)正壓(ya)(ya)而(er)被不(bu)斷(duan)地(di)擠出罐(guan)(guan)(guan)(guan)(guan)外。該階段油(you)(you)(you)(you)(you)(you)(you)(you)氣(qi)(qi)(qi)(qi)排(pai)放量相對(dui)較大(da)(da),油(you)(you)(you)(you)(you)(you)(you)(you)庫油(you)(you)(you)(you)(you)(you)(you)(you)氣(qi)(qi)(qi)(qi)回收(shou)(shou)(shou)應(ying)主(zhu)要(yao)針對(dui)此階段的(de)(de)油(you)(you)(you)(you)(you)(you)(you)(you)氣(qi)(qi)(qi)(qi)排(pai)放進行(xing)(xing)收(shou)(shou)(shou)集(ji)和(he)處理,同時(shi)對(dui)儲油(you)(you)(you)(you)(you)(you)(you)(you)階段中密封儲存在油(you)(you)(you)(you)(you)(you)(you)(you)罐(guan)(guan)(guan)(guan)(guan)內(nei)(nei)的(de)(de)油(you)(you)(you)(you)(you)(you)(you)(you)氣(qi)(qi)(qi)(qi)加(jia)以(yi)收(shou)(shou)(shou)集(ji)和(he)處理。根據國標規定,發(fa)油(you)(you)(you)(you)(you)(you)(you)(you)過程采用(yong)(yong)底部(bu)裝(zhuang)(zhuang)油(you)(you)(you)(you)(you)(you)(you)(you)方式(shi),防止油(you)(you)(you)(you)(you)(you)(you)(you)罐(guan)(guan)(guan)(guan)(guan)開啟瞬間的(de)(de)油(you)(you)(you)(you)(you)(you)(you)(you)氣(qi)(qi)(qi)(qi)排(pai)放;通過油(you)(you)(you)(you)(you)(you)(you)(you)氣(qi)(qi)(qi)(qi)回收(shou)(shou)(shou)裝(zhuang)(zhuang)置的(de)(de)收(shou)(shou)(shou)集(ji)系統對(dui)罐(guan)(guan)(guan)(guan)(guan)內(nei)(nei)油(you)(you)(you)(you)(you)(you)(you)(you)氣(qi)(qi)(qi)(qi)進行(xing)(xing)收(shou)(shou)(shou)集(ji),同時(shi)在收(shou)(shou)(shou)集(ji)系統配設(she)測壓(ya)(ya)儀表,以(yi)保(bao)證罐(guan)(guan)(guan)(guan)(guan)內(nei)(nei)壓(ya)(ya)力適宜(yi);裝(zhuang)(zhuang)油(you)(you)(you)(you)(you)(you)(you)(you)和(he)油(you)(you)(you)(you)(you)(you)(you)(you)氣(qi)(qi)(qi)(qi)輸送接口采用(yong)(yong)DN100密封式(shi)快速接頭,以(yi)減(jian)少油(you)(you)(you)(you)(you)(you)(you)(you)氣(qi)(qi)(qi)(qi)排(pai)放。
