Dynamic modelling of induced draft cooling towers with parallel heat exchangers, pumps and cooling water network

Viljoen, Johannes Henning; Muller, Cornelius Jacobus; Craig, Ian Keith (Elsevier, 2018-08)

In the process industries, cooling capacity is an important enabler for the facility to manufacture on specification product. The cooling water network is an important part of the over-all cooling system of the facility. ...
Economic hybrid non-linear model predictive control of a dual circuit induced draft cooling water system

Muller, Cornelius Jacobus; Craig, Ian Keith (Elsevier, 2017-05)

Petrochemical plants require the addition and removal of energy to and from the process and the movement of material to, from, and within the process piping and vessels. These fundamental mass and energy transfer requirements ...
Energy reduction for a dual circuit cooling water system using advanced regulatory control

Muller, Cornelius Jacobus; Craig, Ian Keith (Elsevier, 2016-06)

Various process utilities are used in the petrochemical industry as auxiliary variables to facilitate the addition/removal of energy to/from the process, power process equipment and inhibit unwanted reaction. Optimisation ...
Fuel gas blending benchmark for economic performance evaluation of advanced control and state estimation

Ricker, N.L.; Muller, Cornelius Jacobus; Craig, Ian Keith (Elsevier, 2012-07)

A simulation of a fuel gas blending process and its measurement system is proposed as a benchmark test case for advanced control and state estimation. The simulation represents an industrial facility and employs a ...
Hybrid nonlinear model predictive control of a cooling water network

Viljoen, Johannes Henning; Muller, Cornelius Jacobus; Craig, Ian Keith (Elsevier, 2020-04)

A Hybrid Nonlinear Model Predictive Control (HNMPC) strategy is developed for temperature control and power consumption minimisation of a cooling water network. The HNMPC uses a gradient descent optimisation algorithm for ...
Modelling of a dual circuit induced draft cooling water system for control and optimisation purposes

Muller, Cornelius Jacobus; Craig, Ian Keith (Elsevier, 2015-01)

The successful operation of any petrochemical plant is dependent on the use of several utilities whichmay include electricity, steam, compressed air, cooling media, refrigeration media, nitrogen, condensateand fuel gas. ...
Modelling, validation, and control of an industrial fuel gas blending system

Muller, Cornelius Jacobus; Craig, Ian Keith; Ricker, N.L. (Elsevier, 2011-04)

In industrial fuel gas preparation, several compositional properties must be controlled within specified limits. This allows client plants to burn the gas safely and with consistent heat production. The variables to be ...
