SUMMARY: The use of optical brightening agent (OBA) and High-yield Pulp (HYP) in fine paper productionis driven by enhanced brightness requirements and reduced manufacturing cost. Due to the fact that HYP contains high amount of lignin, the OBA quenching effect, defined as the decrease in the OBA brightening efficiency due to the presence of lignin in the HYP-containing furnish is a concern. The OBA brightening in pulp furnish containing HYP, together with wet end chemicals (PEI, CPAM, APAM, cationic starch) and fillers (PCC or GCC), were investigated. It was found that the OBA brightening efficiency decreased with increased HYP content in the furnish. Polyethylenimine (PEI) had the most noticeable negative effect on the OBA brightening efficiency. PCC filler produced greater brightness gain than GCC filler at the same OBA dosage.

WeightedaveragesanddistributionsoffibrecharacteristicsofmechanicalpulpsPartI:Alternativemethodsofweightingdatafromanopticalanalyserproduceaveragesthatrankpulpsdifferently

SREYIER ?STERLING O FERRITSIUS R FERRITSIUS J ST?NGMYR

SUMMARY: To improve the operation and energy efficiency of mechanical pulping processes, the effect of each stage of the process on the fibres should be carefully evaluated. Fibre-data from an optical analyser were used to predict tensile index by calculatingBIN(Bonding abilityINfluence). Wall volume weighted averages of wall thickness index and fibrillation index gave the most accurate predictions of the tensile index of laboratory sheets made from long fibre fractions of various mechanical pulps. Fibre width index, when used as a single factor, reduced the accuracy of the model. The ranking of some samples changed when fibre width was wall volume weighted compared to arithmetic. When fibre width was combined with wall thickness to give a collapse resistance index, no rankings changed. Weighted averages based on squared fibre length (length2) showed poor correlation to wall volume weighted averages for cross-sectional fibre dimensions, and resulted in different levels of correlation to long fibre tensile index for the five evaluated pulps.

InterstagefractionationandlowconsistencyrefiningforTMPPart1:Energyconsumptionandpulpproperties

MY-MUSTAPHA LEMRINI ROBERT LANOUETTE GASTON MICHAUD

SUMMARY: The impact of an interstage fractionation followed by a low consistency refining (LCR) stage prior to a high consistency refining (HCR) was studied. We present the resulting energy consumption and pulp property changes when different energy input ratios (energy at LCR/energy at HCR) are applied to the long fibre fraction obtained at the interstage screening.

Three basic processes were studied: (1) a high consistency (HC) refining, (2) a low consistency (LC) refining, and (3) fractionation followed by an LCR stage and an HCR stage in series applied to the long fibre fraction, and recombination. We applied different energy levels to the long fibre fraction, from 100% of the secondary stage refining energy at LC and 0% at HC to 0% applied at LC and 100% at HC, as well as three intermediate ratios of the energy applied at LC. Properties were altered when excessive energy was transferred to the LCR. Adjustment of the LCR/HCR ratio prevented large losses in terms of tensile and tear strength. For 17 to 29% energy savings (to reach 100 CSF), the loss in tensile increased from 6 to 9%, whereas the tear changed insignificantly. Fractionation is significant in altering the energy-pulp property relationship, except in the case of tensile strength. Overall these results demonstrate that there is a considerable range of options for reducing the energy input while maintaining the quality of the final pulp through the use of fractionation and a combination of low and high consistency processes.

TMP的纖維分級(jí)和低濃打漿第1部分：能耗和紙漿性能

MY-MUSTAPHA LEMRINI ROBERT LANOUETTE GASTON MICHAUD

摘要：研究了在高濃打漿(HCR)之前進(jìn)行纖維分級(jí)，然后進(jìn)行低濃打漿(LCR)對(duì)能耗和紙漿性能的影響。闡述了在對(duì)TMP進(jìn)行纖維分級(jí)所獲得的長(zhǎng)纖維部分，應(yīng)用不同的能量輸入比(HCR的打漿能耗/LCR的打漿能耗)時(shí)，得到的總能耗和紙漿性質(zhì)的不同。

研究包括3個(gè)方面：①高濃度(HC)打漿；②低濃度(LC)打漿；③纖維分級(jí)后對(duì)長(zhǎng)纖維組分先低濃打漿后高濃打漿，然后與短纖維組分混合。對(duì)長(zhǎng)纖維組分打漿采用不同的能級(jí)，從低濃段打漿使用100%的能量(高濃段為0)，到低濃段使用0(高濃段為100%)，以及介于這兩種情況之間的3種不同低濃和高濃能量分配比例。當(dāng)過多的能量分配到低濃打漿時(shí)，漿料的特性發(fā)生改變。調(diào)整低濃/高濃能量分配比例可以防止紙張拉伸和撕裂強(qiáng)度方面的巨大損失。在紙漿游離度達(dá)到100 CSF的情況下，當(dāng)磨漿能耗節(jié)省17%～29%時(shí)，抗張強(qiáng)度損失從6%增加到9%，而撕裂強(qiáng)度變化不大。除了在抗張強(qiáng)度，纖維長(zhǎng)度分級(jí)能顯著改變能耗與紙漿性能的關(guān)系。結(jié)果表明，通過對(duì)纖維分級(jí)以及低濃和高濃打漿相結(jié)合，有很多的選擇去實(shí)現(xiàn)打漿能耗減少，同時(shí)保持最終的紙漿質(zhì)量。

Integrationofelectrolysistoproducehydrogenandoxygeninapulpmillprocess

KATJA KUPARINEN ESA VAKKILAINEN PETER RYDER

SUMMARY: The pulp and paper industry faces demand for totally carbon free production. Due to local conditions, there are challenges to sell produced additional electricity. A novel way, generating hydrogen and oxygen through the electrolysis of water can decarbonize the largest fossil carbon dioxide producing equipment, the lime kiln. The oxygen produced can be used for generation of bleaching chemicals, and also for effluent treatment. The operation and capacity of the recovery boiler can be improved by oxygen use. Using excess electricity of a typical, large South-American pulp mill, 73% of the heat demand of the lime kiln can be covered with hydrogen and the produced amount of oxygen exceeds the mill’s oxygen requirement. The profitability of the integration depends on the other possible uses for electricity. When sales price for electricity is low or purchased oil price is high electrolysis can decrease the operating costs of a modern pulp mill.

SUMMARY: The anatomical characteristics of terap (Artocarpuselasticus), medang (Neolitsealatifolia) and balikangin (Alphitoniaexcelsa) were studied to identify new pulpwood resources among lesser-known species native to Indonesia. The mean values of fibre and vessel element lengths were 1.55 and 0.42 mm in terap, 1.21 and 0.56 mm in medang and 1.14 and 0.52 mm in balikangin. The mean proportions of vessel, fibre, ray parenchyma, axial parenchyma and cell wall were 10.5%, 48.5%, 18.3%, 22.7% and 45.4% in terap, 21.6%, 49.7%, 13.8%, 14.9% and 50.5% in medang and 15.6%, 67.7%, 10.3%, 6.4% and 46.4% in balikangin. The anatomical characteristics of the three species were similar to those of fast-growing tree species used as pulpwood. Fibre diameter and cell wall percentage were significantly correlated with basic density in all species, indicating that diameter of wood fibre and cell wall percentages affect basic density values of all three woods.
