The use of optimisation modelling for energy recovery investment decision making

Venter, P.V.Z.; Terblanche, S.E.; Van Eldik, M. (IEEE, 2019)

Investment decision making is a common occurrence for any engineering company. These investments include any possibility from relative inexpensive to extremely costly equipment. When power generation turbine procurements ...

A methodology to determine best-suited waiting-time periods for turbine start-up under fluctuating resources

Venter, P.V.Z. (IEEE, 2019)

— It is not uncommon for engineering process plants to comprise energy recovery. When power generation takes place under such circumstances, the nature of interlinked processes may result in fluctuating resource availability. ...

Computational cost of an exergy-based fault detection scheme implemented in a commercial process simulator

Marais, Henri; Van Schoor, George; Uren, Kenneth R. (Elsevier, 2019)

Energy-based fault detection and isolation (FDI) schemes show promise in terms of applicability to petrochemical industries and the broader process industries. Model-based FDI schemes offer pronounced advantages over more ...

Utilising fluctuating off-gases more efficiently in a power co-generation environment through less flaring

Venter, P.V.Z.; Terblanche, S.E.; Van Eldik, M. (IEEE, 2016)

Common engineering practice is to generate steam from burnable off-gases, in boiler houses, where excess steam is allocated for power generation after plant requirements are met. If the quantities or chemical composition ...

Implementing an optimisation model for turbine investment selection under fluctuating steam productions

Venter, P.V.Z.; Terblanche, S.E.; Van Eldik, M. (IEEE, 2016)

Engineering plants typically have a variety of interlinked production chains, where process flows are dependent on upstream or downstream events. Raw material feeds may fluctuate over time, resulting in fluctuating off-gas ...

A simulation strategy to optimize the design of internet enabled logistics services

Lusanga, P.K.; Hoffman, A.J.; De Coning, A.; Bhero, E. (IEEE, 2014)

The emergence of advanced communication technology has created opportunities to improve transportation in supply chains across the globe. In this paper the main contributors to inefficiencies in present road transportation ...

Simulation of washability and liberation information from photographs

Dorland, H.C.; Campbell, Q.P.; Le Roux, M.; McMillan, K.; Dorland, M.I. (Springer, 2016)

Imagine that a sample of coal could be crushed unlimited times to the same or different top size; a different washability would be obtained for each crushing experiment. Depending on the size and distribution of the raw ...
