TL;DR: Application of THP improves the financial and environmental performance compared with conventional AD, and producing bio-methane for grid injection is attractive financially but has the worst environmental impact of all the scenarios, suggesting that the current UK financial incentive policy for bio- methane is not driving best environmental practice.

TL;DR: In this article, the properties of clusters of particles travelling near the riser wall are predicted from experimental data published in the literature on vertical risers ranging from laboratory to industrial scale, and expressions for predicting the size, shape, density, wall film coverage and velocity of particle clusters are presented.
193 citations
TL;DR: In this paper, the cavitation number at the choked condition is a function of the ratio of the orifice diameter (d) to the pipe diameter (D), where D is the dimensionless jet length.
152 citations
TL;DR: In this article, the authors used the fast response particle RTD technique developed by Harris et al. to measure the particle residence time distribution (RTD) made in the riser of a square cross section, cold model, circulating fluidised bed.

TL;DR: In this article, the most popular methods of sewage sludge management and associated unit operations and processes referring to them are presented, such as: reclamation and adaptation of lands to specific needs; plant cultivation not intended for consumption or for production of food; usage in agriculture, usage in building; recovery of phosphorus, rare earth metals or fats and usage in industry; producing combustible pellets, granulates or other usable materials such as absorbents; and storage on territory of treatment plant and landfills.

TL;DR: An overview of microalgal cell disruption processes which are potentially suitable for large scale lipid extractions and the results show that further research and innovation is required for the sustainable cell disruption and lipid extraction from microalgae.
Abstract: Some species of microalgae have high lipid yields; however, all species of microalgae, with the only known exception of Botryococcus braunii, have their lipids located inside the cells. The toughness of cell walls and cell membranes of microalgae makes the lipids not readily available for extraction and means that cell disruption an energy intensive process. The cell disruption energy required may become a critical consideration in the production of low valued commodities such as biofuels. This study provides an overview of microalgal cell disruption processes which are potentially suitable for large scale lipid extractions. The energy requirements of these processes were calculated and then compared with estimates of the theoretical minimum energy required for disruption. The results show that the mechanical disruption methods considered were highly energy inefficient when conducted under laboratory conditions and required a specific energy consumption of at least 33 MJ kg −1 of dry biomass. Thus the specific energy consumption is greater than the energy recoverable from the microalgae and is also a factor of 10 5 greater than that the estimated minimum theoretical energy consumption. This result clearly shows that further research and innovation is required for the sustainable cell disruption and lipid extraction from microalgae.
