Table 3 Energy evaluation at several conditions of extractive processes for ABE recovery from fermentation Process Substrate (g/l) Xa ABE yieldb Butanol titer (g/l) ABE titer (g/l) Pressure EBC (atm).
Both instruments employ extractive sample systems to condition the moisture-saturated flue gas.
In this study, the optimum condition for extractive bioconversion of poly-ϵ-caprolactone using Burkholderia cepacia lipase in an aqueous two-phase system (ATPS) was established.
This paper sets out to present a systematic procedure, using a process simulator (Aspen Plus®), in order to obtain the optimum condition for extractive distillation columns.
The cultivation performance of P. acidilactici in the constant fed-batch fermentation coupled with extractive fermentation using the condition of dispersed anion-exchange resin were conducted at feeding rate of 0.015 L/h.
The EU's future policy must promote investment which is sustainable, respects the environment (particularly on the field of extractive industries) and encourages good working conditions in the enterprises subject to foreign investment.
In South Africa, conditions for workers in the extractives industry can be perilous and striking workers are sometimes met with fierce resistance; we were reminded of how severe this has been last month, when the Farlam commission released its report into the massacre of 44 people during a strike at a mine in 2012.
These improvements could include the design of an organic solvent (for instance, one with better sugar-extractive capabilities) and the optimization of system conditions such that the amount of organic solvent is reduced, thereby lowering the amount of acid/base chemicals required downstream.
For example, Southern Africa has seen enormous movement of workers in the extractive industries, living and working under the harshest conditions, resulting in massive burdens of silicosis in former mine workers in the region [ 30, 31].
Cell wall composition analysis for all biological replicates was performed in accordance with NREL Determination of Structural Carbohydrates and Lignin in Biomass [ 20] using material extracted using an ethanol-water mix in a Dionex Accelerated Solvent Extractor 300 (Dionex, Sunnyvale, California, USA) under conditions described in NREL Determination of Extractives in Biomass [ 21].
