【摘要】：陜北地區(qū)因其得天獨厚的煤炭資源,在國家級能源領域中享有舉足輕重的地位。蘭炭生產(chǎn)是我省陜北主導產(chǎn)業(yè)之一。本文通過分析Toscoal工藝、魯奇魯爾工藝、大連理工大學DG低溫熱解工藝、氣體熱載體直立爐(魯奇爐)熱解工藝、多段回轉(zhuǎn)爐熱解工藝(MRF工藝)及陜北三江SJ低溫干餾爐工藝的優(yōu)缺點,指出正在廣泛使用的陜北三江SJ低溫干餾爐既是對國內(nèi)熱解爐型進行總結(jié)改良,又吸收了國外相關(guān)爐型的優(yōu)點并結(jié)合當?shù)孛嘿|(zhì)特點開發(fā)的一種新爐型。相比于之前的土法煉焦,現(xiàn)在的蘭炭產(chǎn)業(yè)無論是規(guī)模上,還是裝置更新程度上都有了非常大的改進。但是,由于蘭炭生產(chǎn)企業(yè)技術(shù)人才短缺,從業(yè)技術(shù)人員專業(yè)素質(zhì)較低,生產(chǎn)管理人員的頻繁失誤,產(chǎn)品焦油、煤氣又為易燃易爆易中毒的危險化學品,因此,在生產(chǎn)過程中存在著巨大的風險,可能造成爆炸、火災、人員傷亡及環(huán)境危害等危險。所以選擇一個合適的風險研究分析方法對過程風險進行分析,增強對存在風險的可控性就顯得尤為重要。通過比對6種化工安全系統(tǒng)分析方法,HAZOP(危險與可操作性分析)分析作為查找生產(chǎn)工藝隱患的有效方法,對于危險分析有良好的效果,結(jié)合我省煤化工企業(yè)特點,加大對該分析方法的推廣應用,既符合我省實際情況,又能與國際的工藝安全管理模式接軌。本文采用HAZOP分析方法對蘭炭工藝進行安全分析,查找工藝缺陷和安全隱患。根據(jù)工藝的設計意圖,將工藝劃分為6個節(jié)點,通過節(jié)點對其安全性進行全面系統(tǒng)的分析。分析結(jié)果表明,干餾爐的空氣流量、爐頂壓力、煤氣中氧氣含量、煤氣管道泄漏、氣柜水槽液位高低及溫度、焦油儲罐泄漏都會對工藝安全產(chǎn)生影響,針對上述高風險后果,在現(xiàn)有安全措施基礎上,提出措施進行整改,增強生產(chǎn)過程的安全性,旨在對相關(guān)從事該工藝的人員提出一些技術(shù)指導。
[Abstract]:Because of its unique coal resources, Northern Shaanxi enjoys an important position in the national energy field. Carbon production is one of the leading industries in Northern Shaanxi Province. This paper analyzes the Toscoal process, rulchruhr process, the DG pyrolysis process of Dalian University of Technology, the pyrolysis process of the gas heat carrier erect furnace (Lu Qilu), and the multi segment rotation. The advantages and disadvantages of the furnace pyrolysis process (MRF process) and the Sanjiang SJ low temperature dry distillation furnace in Northern Shaanxi are pointed out. It is pointed out that the widely used Sanjiang SJ low temperature dry distillation furnace is both a summary improvement of the domestic pyrolysis furnace type and a new furnace type developed by combining the advantages of the related furnace type abroad and combined with the local coal quality. However, because of the shortage of technical personnel, the low professional quality of the employees, the frequent mistakes of the production managers, the product tar and gas are dangerous chemicals which are inflammable, explosive and easy to be poisoned. There are huge risks in the process of production, which may lead to explosions, fires, casualties and environmental hazards. So it is particularly important to choose a suitable risk analysis method to analyze the process risk and enhance the controllability of the existence of the risk. By comparing 6 chemical safety system analysis methods, HAZOP (danger and possible) As an effective method to find out the hidden trouble in the production process, the analysis has good effect on the risk analysis, and combined with the characteristics of the coal chemical enterprise in our province, the application of the analysis method is increased, which is in line with the actual situation in our province, and can be connected with the international process safety management model. This paper adopts the HAZOP analysis method to Lan Tangong According to the design intention of the process, the process is divided into 6 nodes, and the safety of the furnace is analyzed comprehensively and systematically. The results show that the air flow, the pressure of the furnace top, the oxygen content in the gas, the leakage of the gas pipeline, the level and temperature of the tank tank level. The leakage of the tar tank will affect the safety of the process. On the basis of the existing safety measures, measures are put forward on the basis of the existing safety measures to improve the safety of the production process. Some technical guidance for the personnel involved in the process is put forward.
