摘 要
近年来,石化企业安全事故频发,损失惨重。化工罐区多为易燃易爆的危险化学品,存在重大安全隐患。对罐区进行自动化系统设计,实现罐区工艺实时监控,不仅可以很大程度降低危险事故发生的频率,保障操作人员的安全,而且可以增强系统稳定型,提高化工生产效率及品质。
本文主要针对某化工厂年产10000吨苯基氯硅烷的罐区工艺进行自动化系统设计。罐区划分为六个罐组,其中包括11个原料储罐、6个中间罐、14个产品罐、4个事故罐以及3个预留罐。本文主要设计内容为根据苯基氯硅烷整体生产工艺整理出罐区各储罐工艺流程;依据储罐工艺流程设计出各储罐控制工艺并进行相关仪表选型;在储罐工艺流程及控制工艺的基础上,选用西门子SIMATIC PCS7构建罐区DCS控制系统,进行系统软、硬件设计,实现储罐温度、压力、液位的实时监控、紧急安全联锁以及工艺组态仿真等功能。通过本次罐区自动化系统设计,改变原本现场操作人员传统手动控制方式、降低劳动强度,保障人员财产安全,同时优化罐区生产工艺,使其更加安全平稳运行。 [资料来源:http://Doc163.com]

Automatic system design of a chemical plant with an annual output of 10000 tons of phenylchlorosilane tank area
Abstract
In recent years, the safety accidents have taken place frequently, petrochemical enterprises at a heavy cost. Most of the chemical tank areas are inflammable and explosive dangerous chemicals, and there are significant safety risks. The automatic system design of the tank area and the real-time monitoring of the process of the tank area can not only greatly reduce the frequency of dangerous accidents and ensure the safety of operators, but also enhance the stability of the system and improve the efficiency and quality of chemical production.
This paper focuses on the design of automatic system for the tank yard process of a chemical plant with an annual output of 10,000 tons of phenylchlorosilane. The tank area is divided into six tank groups, including 11 raw material storage tanks, 6 intermediate tanks, 14 product tanks, 4 emergency tanks and 3 reserve tanks. In this paper, the main design content is based on the overall production process of phenylchlorosilane finishing tank area each tank process flow; then, designing the tank control process and selecting the model of instrument; after finishing above works, applySiemens SIMATIC PCS7to construct the tankarea DCS control system, and the system software and hardware are designed to realize real-time monitoring of tank temperature, pressure and liquid level, emergency safety interlock and process configuration simulation and other functions. Through the tank area automation system design, change the original field operator traditional manual control mode, reduce labor intensity, ensure the safety of personnel and property, at the same time optimize the tank area production process, make it more safe and stable operation.
