摘要

摘要 本文深入研究了工业流体催化裂化的复杂动态,这是炼制通用油品 (UOP) 的一个关键过程。这项研究的核心是努力推导出一个全面的数学模型,以捕捉 UOP 流体催化裂化装置内质量和能量平衡的本质。研究的核心目标是在两种不同的运行情况下探索和应用比率控制算法。在第一种情况下,配比控制器被置于再生器输入空气控制阀之后,而在第二种情况下,配比控制器被置于控制阀之前。这里的主要重点是对立管和再生器反应器的出口温度进行精细控制。研究利用 MATLAB 软件的功能,有条不紊地模拟了流体催化裂化过程。研究引入了燃气油进料率、燃气油进料温度和空气温度等变量,以严格测试拟议比率控制算法的功效。调查结果显示,情况一的比率控制明显优于情况二。在立管反应器和再生器反应器中,这一优势体现在稳定性和运行效率的提高上,具体表现为积分绝对误差(IAE)读数更低,更快地达到预定的设定温度。

Design of a Ratio Control Algorithm for a Fluid Catalytic Cracking System in an Universal Oil Product Context

Abstract

This paper delves into the intricate dynamics of industrial fluid catalytic cracking, a pivotal process in refining universal oil products (UOP). At the core of this investigation is the endeavor to derive a comprehensive mathematical model that captures the essence of mass and energy balances within a UOP fluid catalytic cracking unit. The study’s central objective is to explore and apply a ratio control algorithm in two distinct operational scenarios. In the first scenario, the ratio controller is strategically positioned after the control valve for the regenerator’s input air, while in the second, it precedes the control valve. The primary focus here is the meticulous control of outlet temperatures for both the riser and regenerator reactors. Leveraging the capabilities of MATLAB software, the research methodically simulates the fluid catalytic cracking process. It introduces variables such as the gas oil feed rate, along with the temperatures of the gas oil feed and air, to rigorously test the efficacy of the proposed ratio control algorithm. The results of this investigation reveal a notable superiority of the ratio control in case one over case two. In the riser and regenerator reactors, this advantage is demonstrated by improved stability and operational efficiency, as evidenced by lower integral absolute error (IAE) readings and a quicker approach to the intended setpoint temperatures.

期刊介绍: Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas. Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
