High-gravity technology ensures a successful implementation of cellulose to ethanol conversion as a cost-competitive process.
Central topics are static mixers, compact heat exchangers, high-gravity technology, reactive separations devices (e.g. reactive distillation, reactive absorption), and more advanced distillation technologies such as dividing-wall column.
Very high gravity (VHG) fermentation technology was subsequently carried out to achieve a high ethanol concentration at 86.4 g/L.
In this paper, a novel method, the high gravity reactive precipitation (HGRP) technology, of manufacturing CaCO3 nanoparticles, presently scaled-up to an annual capacity of 10,000 tons, is presented.
This paper reviews our work on the fundamental principles of high gravity controlled precipitation (HGCP) technology, and its applications in the production of drug nanoparticles, which was carried out in a rotating packed bed (RPB).
As a result, development of alternative methods such as supercritical fluid technology and high gravity controlled precipitation becomes important.
The range of technologies is substantial, including high gravity fields (the HiGee distillation unit) and microwaves for drying.
Research has been conducted on understanding diacetyl formation and reducing diacetyl production, but the area still remains a challenge, especially in regard to new brewing technologies, such as continuous fermentation, high gravity brewing and, in particular, any process change which results in shorter fermentation time (Boulton and Quain 2001; Nienow et al. 2011; Verbelen et al. 2008, 2009).
Now he only drinks "high gravity liquor to feel low gravity".
