【摘要】：現(xiàn)今世界石油化工企業(yè)生產(chǎn)規(guī)模越來越大，更是我國國民經(jīng)濟(jì)的支柱產(chǎn)業(yè)之一，在國民經(jīng)濟(jì)產(chǎn)業(yè)中占有重要地位。然而石化企業(yè)所涉及到的危險有害物質(zhì)和能量也在不斷的增多，且系統(tǒng)中的生產(chǎn)設(shè)備管線繁多、操作復(fù)雜、工藝過程連續(xù)性強(qiáng)，自動化程度高等特點。因此，，系統(tǒng)中的事故隱患的種類極為繁雜，稍有不慎就會產(chǎn)生非常嚴(yán)重的事故后果，預(yù)防事故的發(fā)生就顯得尤為的重要。 在合成樹脂中，聚丙烯是發(fā)展最快的產(chǎn)品之一，是具有廣泛用途的聚合物原料。然而丙烯聚合反應(yīng)裝置常常是在較高的溫度和壓力下進(jìn)行的強(qiáng)放熱的化學(xué)反應(yīng)，所使用的原料、添加劑、助催化劑，如丙烯、氫氣、三乙基鋁等，具有自燃點低、爆炸極限寬等特點，是易燃、易爆和有毒物質(zhì)。因此，提高工藝過程安全性對保證丙烯聚合反應(yīng)裝置安全、穩(wěn)定運行至關(guān)重要。 本文主要是針對純定性分析與推理的SDG-HAZOP分析結(jié)果出現(xiàn)冗繁、主次不清等問題。層次分析法（Analytic Hierarchy Process，AHP）傳統(tǒng)的1～9比例標(biāo)度不合理的基礎(chǔ)上，比較1～9標(biāo)度、9／9～9／1標(biāo)度、10／10～18／2標(biāo)度、指數(shù)標(biāo)度等四種標(biāo)度，從中選取最優(yōu)標(biāo)度。提出了基于改進(jìn)標(biāo)度層次分析法的SDG-HAZOP一種安全綜合定量評價模型。 以中石化武漢分公司的聚丙烯生產(chǎn)裝置為應(yīng)用背景，運用基于改進(jìn)標(biāo)度層次分析法的SDG-HAZOP綜合評價模型對丙烯聚合反應(yīng)生產(chǎn)工藝進(jìn)行安全分析，計算SDG-HAZOP各個危險路徑的相對重要度，能有效地對冗繁、主次不清的HAZOP分析結(jié)果按危險路徑相對重要度大小進(jìn)行排序，并篩除掉相對重要度小的路徑，能比較有針對性的對重要危險隱患提出相應(yīng)的預(yù)防和改進(jìn)措施。 同時，針對SDG-HAZOP分析反應(yīng)過程高溫、高壓，易引發(fā)火災(zāi)爆炸等危險特性，提出基于SDG-HAZOP的FTA定性分析方法對丙烯聚合反應(yīng)裝置生產(chǎn)過程中存在的火災(zāi)爆炸危險性進(jìn)行安全分析，能夠全面地識別出該裝置存在的安全隱患，揭示系統(tǒng)內(nèi)固有的或潛在的危險因素，降低裝置操作的危險性，預(yù)防燃爆事故的發(fā)生。
[Abstract]:Nowadays, the production scale of petrochemical enterprises in the world is getting larger and larger, and it is one of the pillar industries of our national economy, which occupies an important position in the national economy industry. However, the hazardous and harmful substances and energy involved in petrochemical enterprises are also increasing, and the production equipment and pipelines in the system are various, the operation is complex, the process continuity is strong, and the degree of automation is high. Therefore, the types of hidden dangers of accidents in the system are extremely complicated, and a little carelessness will lead to very serious accident consequences. It is particularly important to prevent accidents. Among synthetic resins, polypropylene is one of the fastest-growing products. Is a widely used polymer raw materials. However, propylene polymerization units are often highly exothermic chemical reactions at higher temperatures and pressures, using raw materials, additives, cocatalysts, such as propylene, hydrogen, triethylaluminum, etc., with low spontaneous ignition points. The explosion limit is wide and so on, is flammable, explosive and toxic substances. Therefore, it is very important to improve the safety of process to ensure the safety and stable operation of propylene polymerization plant. In this paper, the results of SDG-HAZOP analysis based on pure qualitative analysis and reasoning are complicated and unclear. The Analytic hierarchy process (AHP) is based on the unreasonable scale of 1 / 9 scale, and compares 9 / 9 / 9 / 1 scale with 10 / 10 / 10 / 18 / 2 scale and 10 / 10 / 18 / 2 scale, and selects the best scale. A kind of SDG-HAZOP safety comprehensive quantitative evaluation model based on improved scale Analytic hierarchy process (AHP) is proposed. The application background is polypropylene production plant in Wuhan Branch of Sinopec. Using the SDG-HAZOP comprehensive evaluation model based on the improved scale Analytic hierarchy process (AHP) to analyze the safety of propylene polymerization process and calculate the relative importance of each dangerous path of SDG-HAZOP, the redundancy can be effectively studied. The results of HAZOP analysis are classified according to the relative importance of the dangerous path, and the path with less importance can be removed, and the corresponding prevention and improvement measures for the hidden danger can be put forward. In view of the high temperature, high pressure and easy to cause fire and explosion in the reaction process analyzed by SDG-HAZOP, the FTA qualitative analysis method based on SDG-HAZOP is put forward to analyze the fire explosion risk in the production process of propylene polymerization reactor. It can fully identify the hidden danger of the device, reveal the inherent or potential risk factors in the system, reduce the risk of the operation of the device, and prevent the occurrence of the explosion accident.
