Abstract

The increase in the consumer gas flow rates more than the daily nominated gas quantities are one of the major issues in gas transmission control and operation in Egypt. To enable and allow for implementation of new strategies, adaptive control, network optimizing, planning ahead, simulation and anticipation of continuously variable supply and demand, consumer flow rates need to be limited to the nominated maximum quantities. This can be achieved by retrofitting and implementation of a designated flow limiting or flow override control system onto the existing control systems. The system operation relies on collecting data from different sensors and controlling devices from the local station, then comparing these data with stored ones. The result of the comparison is transmitted to a remote station for taking action. In this paper, a control system for this operation is proposed and tested using Arduino and ZigBee modules.

Abstract

This paper simulates a control for total operation of gasifier system using ladder logic Siemens S7. The used technique is implemented to produce friendly environmental and energy preserve system. In this system a flow transmitter is used to control between the motorized line and an on/off furnace valve sequenced, agricultural waste enter the furnace to burn that produce methanol liquid. there are chimney valve and burner's on/off valve to condensate methanol liquid at vessel depending on the value of pressure or temperature such that for high pressure or temperature parameter the chimney valve will open and burner will be closed and vise verse. Moreover level transmitter is used to indicate Methanol liquid level such that an action will be taken to control the motorized line.
