Future outlook for urban drainage

The lack of flexibility in current drainage infrastructure combined with uncertainty, changing societal needs and demands affect the robustness and resilience of current drainage systems to future pressures. This chapter looks at how new thinking and alternative, more innovative ways to deliver a sustainable, affordable operating model for...

Asset management, operation and maintenance

This chapter introduces asset management for urban drainage systems with a focus on operation and maintenance. Good asset management ensures the performance of assets is in line with the owner and operator's requirements.

Synthesis and optimization of NGL separation as a complex energy-integrated distillation sequence

The synthesis of heat-integrated distillation sequences for energy-efficient separation of zeotropic multicomponent mixtures is complex due to the many interconnected design degrees of freedom. This paper explores the basis on which reliable screening can be carried out. To solve this problem, a screening algorithm has been developed using...
