Fluid flow in hydraulic fluid machinery can be described by the Navier-Stokes equations. The numerical effort for solving partial differential equations typically is too large, however, to permit their use in real-time control applications such as st

Pinch Analysis is a well-known methodology that has achieved great success in increasing process efficiency since its inception in the 1970s. The traditional approach in Pinch Analysis has mainly been concerned with Heat Integration. However, most ch

Heat Exchange Networks (HENs) and Mass Exchange Networks (MENs) have been widely adopted and extensively studied for heat and material recovery to save energy and other resources. However, work recovery can also result in significant energy savings i

Optimisation of a dual mixed refrigerant LNG process is challenging due to its rather complex structure. Therefore, appropriate constraint formulations are essential to solve the optimisation problem. In this paper, the AP-DMR process was optimised t

Heat Integration has achieved a great success in both academic research and industrial applications since the 1970s. Traditional heat integration deals with process streams with temperature changes only. Pressure is an equally important parameter in

Heat Integration is extended to the topic of Heat and Work Integration when pressure changing equipment such as compressors and expanders are included in heat exchanger network design. The latter topic is much more complex since heat and work have di

The appropriate placement of compressors and expanders is studied in this paper. Since both heat and work are involved, the topic is extended from heat integration to the integration of both heat and work. The objective is to minimize exergy consumpt

Oxy-combustion coal based power plants are considered one of the cost effective ways to produce CO2 emission free electricity. Recovery of compression heat and the latent heat from the flue gases can further improve the efficiency of such power plant

The appropriate placement of compressors and expanders was recently shown to be at the pinch temperature, meaning that the inlet temperature to these units should be at the pinch. However, the application of the rule is not obvious when multiple valu
