Specific Scale

The intention of this paper is to give an overview about scaling in sugar factories, with the focus set on beet sugar factories but also including aspects which are specific for cane sugar production. Based on the analyses of some thousand scale samples collected during the last 40 years from sugar factories all over the world typical scale compositions and their abundance depending on factors like region, operation conditions of the factory, effect and type of evaporator are shown. Long time trends in scale composition and their relation to changing conditions in the sugar production are extracted from these data, e.g. the influence of longer campaigns (up to 140 days) on the scale composition in beet sugar factories in Central Europe. Based on its composition and the conditions during factory operation the formation of a specific scale is explained. For each type of scale a method for the removal, proven by laboratory studies and experience gained in the factories, is presented and recommendations are given to reduce or avoid the formation of a specific scale.

To get more insight in the environmental performance of the Suiker Unie beet sugar, Blonk Consultants performed a comparative Life Cycle Assessment (LCA) study on beet sugar, cane sugar and glucose syrup. The system boundaries of the sugar life cycle are set from cradle to regional storage at the Dutch market. For this study 8 different scenarios were evaluated. The first scenario is the actual sugar production at Suiker Unie. Scenario 2 until 7 are different cane sugar scenarios (different countries of origin, surplus electricity production and pre-harvest burning of leaves are considered). Scenario 8 concerns the glucose syrup scenario. An important factor in the environmental impact of 1kg of sugar is the sugar yield per ha. Total sugar yield per ha differs from 9t/ha sugar for sugarcane to 15t/ha sugar for sugar beet (in 2017). Main conclusion is that the production of beet sugar at Suiker Unie has in general a lower impact on climate change, fine particulate matter, land use and water consumption, compared to cane sugar production (in Brazil and India) and glucose syrup. The impact of cane sugar production on climate change and water consumption is highly dependent on the country of origin, especially when land use change is taken into account. The environmental impact of sugar production is highly dependent on the co-production of bioenergy, both for beet and cane sugar.

The article discusses and analyzes the construction of liquid-jet sulfitators used in the beet sugar industry. The importance of sulfitation treatment in the sugar beet processing and raw cane sugar technology is noted and the main advantages of its use at various technological stages are given, namely, preparation of extractant used for diffusion sucrose extraction out of beet cossettes, thin juice processing, thick juice with B- and C-remelts processing, as well as raw cane sugar remelt processing. The advantages and disadvantages of liquid-jet sulfitators in comparison with other constructions are noted and criteria for their improvement are given. It has been noted that the created ejection, which sucks in the sulphitation gas into the contacting chamber, and the fact that the absorption of sulfur dioxide occurs on a larger surface than in other types of structures the main advantages of liquid-jet sulphitators. The main disadvantages are the short length of the contacting chamber, which is insufficient for ensuring complete absorption of sulfur dioxide, as well as instability of the generated ejection when the productivity changes. This determines the criteria given in the article for the improvement of liquid-jet sulfitators. The description of the developed construction of the sulphitator centrifugal-jet nozzle of sugar production liquids is given, which provides: the stability of the sulphitation gas supply in a wide range of plant productivity; stability of the hydroaerodynamic regime of the system «treated liquid – sulphitation gas» inside the sulphitator; sufficient contact time for complete dissolution in the treated liquid of the sulfur anhydride contained in the sulphitation gas. The advantages of the developed centrifugal-jet sulfitators in comparison with typical liquid-jet sulfitators are noted: ensuring the operation range of 50-120% of the nominal capacity (plant production capacity); significant reduction in the technical sulfur consumption for the sulphur anhydride production, which is used as a reagent for the sulfitation treatment of liquids in beet sugar processing; reduction of harmful emissions into the atmosphere due to 100 % sulfur anhydride dissolution in the treated liquid.

Beet sugar production is one of the material-intensive industries, where the volume of raw and auxiliary materials used in production is several times higher than the output of finished products. It is also a source of multi-tonnage secondary resources, i.e. by-products and production waste, the main ones beingAbeet pulp, molasses and filtration sludge. Against the background of the implementation of the Sectoral Program of Beet Sugar Production Development in the Republic of Kazakhstan for 2018-2027, there is a need to create a concept of ecologization of production, which will provide for the development of fundamentally new technologies to ensure minimum waste, combining environmentally friendly methods with cost-effective production of sugar beet and by-products. The bet should be made on low-cost technologies that will minimize production costs and environmental impact. In this article possible variants of sugar beet processing technologies with complex deep processing of waste are offered. The comparison of traditional technology and various variants of progressive technologies of sugar beet processing and production of new products from secondary resources was carried out, which allowed to determine revenue from complex processing of 1 ton of sugar beet.
