Operation Parameters Detection and Control System Design for Ammonia-based Flue Gas Desulfurization Process of Thermal Power Plant

Large scale ammonia-based FGD is a new environmental protection technology almost including all chemical engineering operation units.This type equipment is very strict on process and control system.In this paper,taking the first control project with 2×300MW units ammonia-based FGD in a domestic thermal power plant as an example,an operation parameters detection and control system is designed according to the FGD technical requirements.This control system can make the equipment run stably and reducing ammonia consumption greatly with improving by-product quality,and this ammonia-based FGD equipment can run economically and effectively base on the meeting the requirements of environmental protection.
