【摘要】：伴隨著我國(guó)能源需求的快速增長(zhǎng),LNG將成為天然氣上下游一體化系統(tǒng)中的主要組成部分,大力發(fā)展LNG成為保護(hù)我國(guó)生態(tài)環(huán)境、能源安全及國(guó)家經(jīng)濟(jì)持續(xù)協(xié)調(diào)發(fā)展的關(guān)鍵舉措。而由于LNG具有低溫、高壓、易燃易爆等特性,一旦發(fā)生事故,將造成嚴(yán)重的人員傷亡和巨大的經(jīng)濟(jì)損失。 目前,我國(guó)對(duì)LNG工廠風(fēng)險(xiǎn)的研究正處于起步階段,還沒有形成系統(tǒng)的評(píng)價(jià)方法。為了確定LNG工廠內(nèi)各項(xiàng)設(shè)備的危險(xiǎn)性,找出可能導(dǎo)致事故發(fā)生的主要危險(xiǎn)源,因此需要對(duì)LNG工廠進(jìn)行風(fēng)險(xiǎn)評(píng)價(jià)研究,制定相應(yīng)的對(duì)策措施,以確保工廠生產(chǎn)平穩(wěn)有效的運(yùn)行,減少經(jīng)濟(jì)損失。 本文在對(duì)國(guó)內(nèi)外風(fēng)險(xiǎn)評(píng)價(jià)技術(shù)研究現(xiàn)狀進(jìn)行充分調(diào)研的基礎(chǔ)上,針對(duì)某LNG工廠的實(shí)際生產(chǎn)運(yùn)行情況,從危險(xiǎn)有害物質(zhì)、設(shè)備、場(chǎng)所等方面對(duì)工廠中的危險(xiǎn)有害因素進(jìn)行辨識(shí),最終確定出火災(zāi)、爆炸、低溫為工廠主要危險(xiǎn)因素；并運(yùn)用道化學(xué)火災(zāi)爆炸危險(xiǎn)指數(shù)評(píng)價(jià)法,將該LNG工廠劃分為三個(gè)單元,分別對(duì)各單元進(jìn)行評(píng)價(jià),從而得到相應(yīng)的火災(zāi)爆炸危險(xiǎn)等級(jí)、安全措施補(bǔ)償系數(shù)等。在運(yùn)用道化學(xué)火災(zāi)爆炸危險(xiǎn)指數(shù)評(píng)價(jià)的基礎(chǔ)上,對(duì)該工廠的工藝、設(shè)備等方面作了深入的分析,確定了相應(yīng)的評(píng)價(jià)單元及評(píng)價(jià)方法。在對(duì)危險(xiǎn)有害因素的辯識(shí)與分析的基礎(chǔ)上,做出了安全定性和定量評(píng)價(jià),最后提出了相應(yīng)的安全對(duì)策措施。
[Abstract]:With the rapid growth of energy demand in China, LNG will become the main component of the natural gas upstream and downstream integration system, and the development of LNG will become a key measure to protect the ecological environment, energy security and the sustainable and coordinated development of the national economy. Because LNG has the characteristics of low temperature, high pressure, flammable and explosive, once the accident occurs, it will cause serious casualties and huge economic losses. At present, the study of LNG plant risk in China is at the initial stage, and there is no systematic evaluation method. In order to determine the risk of every equipment in LNG plant and to find out the main hazard source that may lead to accidents, it is necessary to study the risk assessment of LNG plant and make corresponding countermeasures to ensure the smooth and effective operation of the plant. Reduce economic losses. Based on the research of domestic and foreign risk assessment technology, this paper identifies the hazardous factors in a LNG plant from the aspects of hazardous substances, equipment, location and so on, in view of the actual production and operation of a LNG plant. Finally, the fire, explosion and low temperature are identified as the main risk factors in the plant. The LNG plant is divided into three units by using the road chemical fire explosion risk index evaluation method, and each unit is evaluated respectively. Thus, the corresponding fire and explosion hazard grade, safety measures compensation coefficient and so on are obtained. Based on the evaluation of chemical fire and explosion hazard index, the process and equipment of the plant are analyzed, and the corresponding evaluation unit and evaluation method are determined. Based on the identification and analysis of dangerous and harmful factors, the safety qualitative and quantitative evaluation is made, and the corresponding safety countermeasures are put forward.
