19-38 OPTIMIZAREA ECONOMICĂ A UNEI CENTRALE ELECTRICE PE ABUR

THE ECONOMIC OPTIMIZATION OF A STEAM POWER
PLANT
This paper provides an Optimization System for an industrial site. The
real-time system will determine the appropriate loading for various boilers and
steam turbines to best meet the site’s demand for steam at various pressures
and generate electricity. We have intended to perform the optimization across
the plant as a whole using PredictPro, although this technology usually
operates on a single process unit.
To provide the system’s functionality there are a number of possible
approaches, including: a steady-state optimizer, utilizing a process model of the
plant (in our case gains model) and the use of the optimizer functionality within
the PredictPro model predictive controller.
Any power plant that can be described by a “gain matrix” with less
than 40 Manipulated Variables (MV) and 80 Constraints (CV) can be treated by
the application in such a configuration.

19-80 MODELAREA COLOANELOR DE DESORPŢIE UTILIZATE ÎN CAPTAREA DIOXIDULUI DE CARBON

MODELLING OF DESORPTION COLUMNS
USED IN CARBON CAPTURE
PROCESSES
As the CO2 emissions continue to grow due to the increase in demand
of cement, steel, iron, ammonia, natural gas and other products that in the
process of manufacturing produce significant CO2 emissions an alternative
solution needs to be found. The solution is represented by adsorptiondesorption
processes that are being used to capture CO2. This paper will focus
on the desorption column and a modelling algorithm will be presented based on
first principle equations.
Keywords: adsorption desorption, reactive distillation, CO2
