Achieving 50% weight reduction of offshore steam bottoming cycles

Combined-cycle solarised gas turbine with steam, organic and CO2 bottoming cycles

Dish concentrators permit the collection of very high-temperature heat, at temperatures limited only by the properties of the containment vessel material. Using this heat efficiently is a major challenge in the design of energy conversion systems for dish concentrators: the heat must be used either immediately on the dish, or else transported, with losses, to a remote energy conversion device. ...

Improvement of Overall Efficiency in the Gas Transmission Networks: Employing Energy Recovery Systems

This study mainly focuses on enhancing the overall efficiency of gas transmission networks. The authors developed a model with detailed characteristics of compressor and pressure reduction stations. Following this, they suggested three different systems with gas turbine including: organic rankine cycle (ORC), air bottoming cycle (ABC), and ABC along with steam injection (SI-ABC). In addition, u...

Achieving weight loss and avoiding obesity.

The effect of the vast variety of nutrients on metabolic outcome and health is complex. A large number of factors play a role in the type and quantity of food consumed in free-living conditions. It is therefore obvious that prescribing a restrictive diet regimen that favours 1 or 2 nutrients at the expense of the others is a poor tool to manage long-term health and weight.

Application of particle swarm optimization for enhanced cyclic steam stimulation in a offshore heavy oil reservoir

Three different variations of PSO algorithms, i.e. Canonical, Gaussian Bare-bone and Lévy Bare-bone PSO, are tested to optimize the ultimate oil recovery of a large heavy oil reservoir. The performance of these algorithms was compared in terms of convergence behaviour and the final optimization results. It is found that, in general, all three types of PSO methods are able to improve the objecti...
