石化储罐区泄漏监测与消防设备联动要求
①监测系统的主导思想 。油罐区火灾监控系统是以火灾为监测对象,根据防灾要求和特点而设计、构成和工作的,是一种及时发现和通报火情,并采取有效措施控制和扑灭火灾而设置在油罐对象中的自动消防设施,是将油罐火消灭在萌芽状态,最大限度地减少火灾的有力工具。随着社会对消防和救灾抢险工作提出越来越高的要求,消防技术设施和消防技术手段之一,也越来越显示出它的重要性。 
①The main idea of monitoring system. Fire monitoring system in oil tank area is designed, constructed and operated according to the requirements and characteristics of fire prevention. It is an automatic fire control facility that can detect and report fire situation in time, take effective measures to control and extinguish fire and set it in the object of oil tank. It is to extinguish oil tank fire in the budding state to the maximum extent possible. A powerful tool for reducing fires. With the society's increasing demands on fire fighting and disaster relief and rescue work, fire fighting technology facilities and one of the means of fire fighting technology are also increasingly showing its importance.
②监测系统的监测参数。
(1)机械――罐体、阀门、管件以及支撑建筑物的强度;
(2)工艺――储罐内部的压力、温度、液体、成分、以及与储罐内物理化学状态密切相关的流量等;
(3) 气象――风速、风向、气温、气压、温度;
(4)火险――液化石油气包括许多易燃易爆气体,它是由石油经过石油化工厂过程中得到的,主要成分有乙烷、丙烷、丁烷、丙烯丁烯等等,火险分类为甲类。

③泄漏监测要求。根据石化储罐区特殊的火灾危险性和可燃气体及易燃液体泄漏监测实际需要,其消防安全监测参数主要是可燃气体浓度、成分、温度、液位或压力等工艺参数。此外,石化储罐区的火灾监测参数应充分考虑罐区特点来确定,当储存油品为原油等重质油品时,因其含碳量较多,燃烧将产生大量的烟气,火灾探测的重点是对烟气浓度的探测。 
总体来讲,石化储罐区消防安全监测要求是通过对工艺参数和火灾参数的实时监测和数据分析,实现参数异常情况及时报警并预测判断可能的后果,采取有效的联动控制方式,启动消防安全设施及灭火设施。据此,在石化监测环境中工艺参数的监测要求,主要是有效测量各类参数,分析预测石化储罐区的安全状态、事故可能性及火灾危险性,根据判断结果采取相应的安全措施;对火灾参数的监测要求是在火灾初期对烟气浓度、温度、光辐射强度等进行有效监测,综合分析监测数据,及时产生报警信号及联动控制信号,有效启动现场灭火设备。 
③ Leakage monitoring requirements. According to the special fire danger of petrochemical tank area and the actual need of monitoring the leakage of flammable gas and liquid, the main parameters of fire safety monitoring are the concentration, composition, temperature, liquid level or pressure of flammable gas. In addition, the fire monitoring parameters of petrochemical storage tank area should be determined with full consideration of the characteristics of the tank area. When the storage oil is heavy oil such as crude oil, because of its high carbon content, combustion will produce a large amount of smoke. The focus of fire detection is to detect the smoke concentration.
Generally speaking, the requirement of fire safety monitoring in petrochemical storage tank area is to timely alarm and predict the possible consequences of abnormal parameters by real-time monitoring and data analysis of process parameters and fire parameters, and to adopt effective linkage control mode to start fire safety facilities and fire extinguishing facilities. Accordingly, the monitoring requirements of process parameters in petrochemical monitoring environment are mainly effective measurement of various parameters, analysis and prediction of safety status, accident possibility and fire risk in petrochemical storage tank area, and corresponding safety measures are taken according to the judgement results; the monitoring requirements of fire parameters are smoke concentration and temperature in the early stage of fire. Effective monitoring of degree and light radiation intensity, comprehensive analysis of monitoring data, timely generation of alarm signals and linkage control signals, effective start-up of field fire extinguishing equipment.
④消防设备联动控制要求。石化储罐区的消防设备主要包括火灾警报装置、灭火设备及安全操作设备。火灾警报装置是为了在安全参数出现异常或火灾发生时产生及时报警,主要设备有警铃、水力警铃、事故广播等。灭火设备是为了在火灾初期有效的控制火势,及时扑灭初起火灾,主要设备有消防炮、泡沫泵、自动喷淋泵等。安全操作设备是为了在安全参数出现异常时对物料管线及各种控制阀门进行控制和操作,如压力阀等。
