<p style="margin: 0px; padding: 0px; font-size: 16px; color: rgb(51, 51, 51); line-height: 30px;"> <span style="margin: 0px; padding: 0px; font-family: arial, helvetica, sans-serif;">　　1.1 設備制造水平</span></p> <p style="margin: 0px; padding: 0px; font-size: 16px; color: rgb(51, 51, 51); line-height: 30px;"> <span style="margin: 0px; padding: 0px; font-family: arial, helvetica,

)造成加氣時(shí)實(shí)際加氣量比計量加氣量多，而造成加氣站的隱性損耗。還有一部分加氣站流量計采用體積流量計，體積流量計不能夠實(shí)時(shí)采集液體的密度造成較大的偏差。</span></p> <p style="margin: 0px; padding: 0px; font-size: 16px; color: rgb(51, 51, 51); line-height:

rgb(51, 51, 51); line-height: 30px;"> <span style="margin: 0px; padding: 0px; font-family: arial, helvetica, sans-serif;">　　一是卸車(chē)操作不得當，卸車(chē)需要將槽車(chē)壓力增壓到高于儲罐壓力時(shí)才能進(jìn)行，但儲罐經(jīng)過(guò)一段運行時(shí)一般壓力較高，通常能達到0.8MPa以上，而槽車(chē)壓力一般較低，約為0.2MPa左右甚至更低，如果直接對槽車(chē)增壓、且對儲罐排放將會(huì )增加大量排放。另外卸車(chē)完畢后槽車(chē)壓力直接排出，或與儲罐上進(jìn)液進(jìn)行壓力平衡，使槽車(chē)泄壓不到位。造成卸車(chē)損失。另外如卸車(chē)過(guò)程中泵的頻率過(guò)高(要求不超過(guò)95HZ)，在卸車(chē)后期時(shí)容易造成泵池進(jìn)出液流量不平衡，引起泵池排空。</span></p> <p

sans-serif;">　　二是加氣完成的系統處理，加氣完成后，泵會(huì )停止運行，這時(shí)候，泵池及管道中會(huì )有許多殘留液體，這部分液體氣化速度相當快，基本通過(guò)泵后回流管回到儲罐的氣相空間，造成儲罐壓力快速上升，被迫排空儲罐。</span></p> <p style="margin: 0px; padding: 0px; font-size: 16px; color: rgb(51, 51, 51); line-height: 30px;"> <span style="margin: 0px; padding: 0px; font-family: arial, helvetica, sans-serif;">　　三是加氣頻率過(guò)高，儲罐壓力又比較高時(shí)會(huì )造成加液壓力過(guò)高，導致加液安全閥起跳從而造成氣損。(限不能自動(dòng)變頻的設備)四是防控管理不嚴格。儲罐壓力達到排放壓力需進(jìn)行放空時(shí)，操作人員不嚴格監控，壓力降到正常值時(shí)不及時(shí)關(guān)閉放空閥，造成浪費。</span></p> </div> </div> </div> <div id="axn0tm0x" class="fy"

<p>?01、為什么LNG汽化之后在送入氣體分配系統之前需要加入加臭劑？因為L(cháng)NG汽化后是無(wú)色無(wú)味的氣體，加臭便于氣體泄露后引起用戶(hù)的注意。02、LNG火災的特點(diǎn)有哪些？LNG火災的特點(diǎn)是：火焰傳播速度較快；質(zhì)量燃燒速率大（地上和水上燃燒速率分別達到0.106kg/m2s和0.258kg/m2s，約為汽油的2倍）；火焰溫度高、輻射熱強；易形成大面...</p>
