A novel approach for modelling hydrothermal liquefaction (HTL) biocrude is presented, using a combination of fractional distillation data and multi-objective optimisation to simulate the various properties non-dominated sorting genetic algorithm (NSGA-II). The complex composition has made it challenging analyse in process models. Most HTL simulation studies use simple basis limited GC–MS data, ...

Orange essential oil (OEO) is mainly composed of D-Limonene and other oxygenated compounds that contribute to the orange flavor aroma. However, unstable in presence heat, light, water, affecting quality OEO. Therefore, objective this study was fractionate OEO by distillation, both molecular fractionated (hybrid), producing a D-Limonene-rich fraction. The characterized physicochemical tests gas ...

More than 200 kg real waste electrical and electronic equipment (WEEE) shredder residues from a German dismantling plant were treated at 650 °C in demonstration scale thermochemical conversion plant. The focus within this work was the generation, purification, analysis of pyrolysis oil. Subsequent filtration fractional distillation combined to yield basic chemicals high purity. By means distill...

E nergy costs are the largest percentage of a hydrocarbon plant’s operating expenditures. This is especially true of the distillation process, which requires substantial energy consumption. Concerns over recent high costs and economic pressures continually emphasise the need for efficient distillation design and operation without a loss of performance. This article illustrates how energy-effici...

We experimentally demonstrate the two-step distillation of entanglement. The output of a first distillation stage underwent a second distillation step and was made available for subsequent steps. Our experiment displays the realization of the building blocks required for an entanglement distillation scheme that can fully overcome decoherence.

Cache hierarchies play a very important role in bridging the speed gap between processors and memory. As this gap increases, it becomes increasingly important to intelligently design and manage a cache system. The performance of current caches is reduced because more than half of the data that is brought into the cache is never referenced, resulting in very low utilization. We propose line dist...

Essential oils have increasing importance in flavour and fragrance industries. They are obtained by distillation techniques. In order to produce an oil with market potential its optimum production parameters have to be well known prior to its commercial production. Determination of the steam distillation parameters of commercially available Laurel leaves oil in pilot plant scale is described. T...

Reactive distillation has received intense attention due to the well known benefits of integrating distillation with reaction in a single unit. While there are procedures available for the synthesis of non-reactive columns and of reaction-separation systems, the design of reactive distillation columns is still a challenge. This work presents a new synthesis and design methodology for reactive d...
