During the SIT conference in Dubai 2005 a single strike crystallization scheme model based on the way that Russian beet factory operated when refining raw sugar was proposed and suggested that it would be particularly suitable for medium size refineries up to about 2000 t/d RSO (refined sugar output). Now there is operational a 1700 t/d RSO stand-alone refinery that uses the scheme. It melts up to VHP raw sugar with 1200 IU (ICUMSA units) and runs carbonatation followed by a light dosing of PAC (powdered activated carbon) as necessary then double effect evaporation to produce fine liquor. Target color for the fine liquor is 340 IU. The centrifugal run-off needs to be segregated into the higher purity, lower color (so-called white) and lower purity, higher color (so called ‘green’) run-off. The white run-off (about 75%) is sent to white crystallization. The remaining 25% (green run-off) is sent to a three-stage crystallization recovery but, given the high purity regime without affination, the ‘A’ sugar is melted back to fine liquor having been crystallized and purged as if food quality. The results presented in the paper show that the refinery is operating broadly as predicted, producing a refined sugar to EEC 2 standard.

Abstract A new multi-purpose polycarbonate track detector (PCTD)/activated-carbon-fabric (ACF) radon monitor has been recently developed in our laboratory, a basic design of which was used for parametric studies. One 500 μm thick PCTD (3 cm x 3 cm) is used bare for detecting alphas from radon and progeny directly from air and another PCTD (3 cm x 3 cm) covered by an ACF layer (PCTD/ACF) to enhance the PCTD response by radon adsorption on its carbon active sites. The PCTDs were processed by 50 Hz−2 kV electrochemical etching method. The ACF/PCTD sensitivity was enhanced in respect to the PCTD/bare with an amplification factor (AF) defined as ratio of track density on PCTD under ACF to that of PCTD bare. Many ACF-related parameters studied affect the PCTD/ACF response among them thermal annealing of ACF, ACF thickness and distance of ACF layer to the PCTD are reported and discussed in this paper.

<p class="p1">Activated carbon fabric or fiber (ACF) is a novel carbonaceous material with exceptionally high adsorption rate and larger adsorption capacity, that has emerged as a rising star in the field of adsorbents. ACF has many advantages over other commercial porous storage materials such as granular activated carbon and powdered activated carbon in terms of adsorption capacity, well defined microporous structure, stability, flexibility and ease of lamination to various substrates. In the last few years, activated carbon fabrics have gained greater choice of interest for use as an adsorbent material in several fields including nuclear, biological and chemical (NBC) protection suit. Viscose rayon, acetate, polyacrylonitrile, pitch, and phenolic based materials are mainly used as precursors for preparation of ACF. ACF or fibres are generally prepared by process comprising stabilisation, carbonisation and activation of precursors. Reviews recent advances and developments in the field of ACF and their utility as an adsorbent material in various fields including NBC scenario. ACF with unmatchable pore structure and surface characteristics at present, with continued innovations and attention to its key challenges, it is expected that ACF will play a pivotal role in diverse environmental, defence<em>, </em>and civil applications.</p>
