Design And Implementation Of Natural Gas Light Hydrocarbon Recovery Compressor Control System

Natural gas as a strategic national resources like oil and coal,is an important raw material in modern industrial production.The recovery of natural gas,light hydrocarbon,is mainly the recovery of more than C3 of hydrocarbons,and the liquefied petroleum gas(LPG)products are stored in the factory and then transported to the workshop by pipeline;Stable light hydrocarbon products are transported out of the plant after storage which improves the use of natural gas and reduces air pollution.In the past,natural gas light hydrocarbon recovery compressors have been monopolized by foreign manufacturers.We have the control system of compressor for recycling natural gas,the first homemade product in Tarim oilfield as the ground,and we realize the localization of application of the compressor used to dealkylate hydrocarbon.It is summarized which includes The development trend and the current situation on the system of the compressor at home and abroad.what's more,the compressor is recommanded on three aspects:the working mechanism,the nature of network and control requirements.In addition,I design a set of control system of unit control system operation plan,according to the characteristics of compressor equipment control.The software and hardware configuration of the system is described in detail,and it is demonstrated in the thesis included the design and working principle of the unit control system and the working mechanism of software and hardware.In the control system of the unit,the TS3000 triple redundant control system of Triconex of United States is used as the next crew control system,and we use the InTouch software development tool produced by Wonderware Company in the part of monitoring,which configures the screen of the monitoring and control system and compiles the corresponding monitoring program.Thus,the control system has the dynamic monitoring function of the unit process data and it also realizes the anti-Vibration control and sequential start/stop timing control.The state monitoring and analysis system makes a timely and accurate diagnosis in the operation of the unit.The system was brought into product in December 2016 and it has been runingnormally,which helps to obtain a favourable economic benefit.
