Black liquor density table

The main component was found to be xyloseDensity of black liquor is important in the calculation of flow characteristics. Needs a clean strong consistent white liquor with low dead load Needs a consistent weak black liquor that has low foaming fouling and plugging characteristics.

Black liquor stream usually with solids content in the range of 65 wt to 75 wt.

Black liquor density table. Black Liquor Thermal Properties Properties needed for detailed calculations noted in paper. Thermal conductivity Specific heat Cp Heat of vaporization Slide 18 Typical Black Liquor Viscosities Viscosity of room temp water 1 cp mPa-s Viscosity of SAE 30 oil at 80F 200 cp mPa-s BL Dry Solids 18 21 26 34 42 51 70 Temp F 150 180. Black liquor stream usually with solids content in the range of 65 wt to 75 wt.

Inorganic compounds present in black liquor consist mainly of sodium salts and small amounts of potassium calcium magnesium silicon and iron salts. Hendrick and Kent 1992. This liquor formed a deposit which contained 947 polysaccharides.

The main component was found to be xyloseDensity of black liquor is important in the calculation of flow characteristics. The density of black liquor is mainly affected by the concentration of inorganic components. This is a nearlinear function of the dry solids content.

Density depends on the organic and inorganic solids at higher solids content. At very low solids content density. 53 Zeilen However I think the temperature difference would need to be fairly large to.

Eucalyptus black liquor - Density viscosity solids and sodium sulfate contents revisited. Weak black liquor from the pulp mill is typically 15 dry solids or 85 water. Most of this water must be evaporated in order to reach a dry solids level that is adequate for combustion in the recovery boiler.

As-fired black liquor dry solids are between about 65 and 85. During evaporation to this level of dry solids the liquor. Black liquor from straw pulping has about 5500 Btulb on solids compared with 6600 Btulb for black liquor from wood.

A lower residual alkali about 34 gL causes lignin and silica to precipitate during liquor concentration making scaling and high viscosities big problems. Product and company identification. Kapstone charleston kraft llc p.

Chemical composition and physical properties of black liquors and their effects on liquor recovery operation in Brazilian pulp mills.

High solids black liquor 75 with a stable viscosity and Btu Needs a relatively clean green liquor that has a consistent high TTA 75 with good reduction efficiency. Needs a clean strong consistent white liquor with low dead load Needs a consistent weak black liquor that has low foaming fouling and plugging characteristics. Methods used in the physical characterization of black liquor are shown in Table 3.

The solid concentration C ss is obtained by using the oven drying method at controlled temperature and the density ρ liquor is determined by the pycnometric technique. Black liquor calorific ie. The heating value HV is evaluated using TAPPI standard test T684 om-90.

Following this method a. Part 3 Batch and continuous digesters Kyösti Ruuttunen. At the beginningand still todayused in small production pulp mills.

Diameters 24 m allowed pulp amounts of 022 tonsbatch Rotation for better contact between cooking liquid and chips. Black liquor is a substance of highly variable chemical composition. The exact composition is dependent upon wood type the concentration of the components in the white liquor used to digest the wood chips and the actual process parameters.

Exposure limits have not been established for black liquor. Black liquor may contain varying percentages of solids ranging from 2 to 80. The density of black liquor varies from species to species for both wood and non-wood materials.

The sp-gravity of BL at any particular concentration and temperature depends upon the ratio of organic to inorganic matter and increases with an increase in inorganic matter and decreases with an increase in temperature. Table 102-1 presents emission factors for a conventional kraft mill. The most widely used particulate control devices are shown along with the odor reductions through black liquor oxidation and incineration of noncondensable offgases.

Tables 102-2 102-3 102-4 102-5 102-6 and 102-7. The more sugar a liquor has the heavier it will be. Syrups and heavy liqueurs including crèmes and schnapps are considerably heavier than whiskey rum and vodka which contain no sugar additives.

The higher the proof the lighter the liquor is. This is a generalization but orange liqueurs are a good example. Notice that in the chart the 80-proof Cointreau and Grand Marnier liqueurs are considerably.

Black liquor and green liquor densities are measured reliably by radiometric systems which are clamped on to the pipe and provide highly repeatable readings. The measurement is carried out without contact and is therefore unaffected by the high temperature and the chemical properties of the liquor. Installation on existing lines is easily feasible without process downtime.

For version 2 in addition to density data it was decided to also present data on specific gravity and to define the terms used. The data presented in this database are divided between density including mass density and bulk density and specific gravity. Like version 10 the data can be downloaded in Excel format from the INFOODS website.
