عنوان انگلیسی Plantwide Control Structure of the Diethyl Oxalate Process Concerning: Safety and Process Improvement
چکیده انگلیسی مقاله During the regeneration-coupling process, a novel, plantwide control framework for the diethyl oxalate production unit is provided in this article. This study's benefit is that it uses process improvements that do not possess the intricacy and expense of the two prior structures described by Zhu and Luyben. The development of a plantwide control structure for this process was completed in two stages. The efficiency of the process was initially evaluated using a straightforward structure, with the primary goal being to prevent the usage of concentration controllers and complex cascading mechanisms to the greatest extent feasible. Due to the presence of persistent variations in the process effluents in the original structure, it was determined that there were numerous disruptions present that influenced the response during both recycle streams in the process and created variations. During the second phase, using trial and error to implement a functional adjustment in the process, the minimum amount of recycle stream during which the variations were fully removed was separated from the process, and a novel feeding stream was inserted. Following implementing these modifications, it was discovered that the effluent variations of the process are fully removed with just two concentration controllers, and this structure demonstrates instantaneous plantwide control over receiving disturbances.
