Int. J. on Recent Trends in Engineering and Technology,, 9 (1): 7 (July 2013)
Abstract
This paper relates to study of advanced control and
optimization of Ethylene furnace by using Model Predictive
Control Professional (MPCPro) block of deltaV system and
also some efforts are made for Implementation of severity
control for part of Ethylene Furnace. Control and optimization
of Ethylene Furnace is designed for MPCPro block, built in
deltaV control studio. This software package consist of large
number of control modules.
Model of severity control for process zone-2 is developed
for process with regulatory loops and this model is further
used in MPCPro block of deltaV system. Control is generated
using new control definition and then we verify the
performance of process for PID control and for MPC at
supervisory level with regulatory loops. The objective behind
using MPC is there are 4 main challenges to restrict the
process for maximum formation of ethylene are short
residence time, controlled pressure, controlled temperature,
steam to hydrocarbon ratio. The process is also get affected by
the disturbances like Fuel BTU, Feed inlet temperature these
issues are get registered while using MPC
