Feeding browser

Browsers such as mule deer, 0. hcmionus, have proUne-rich salivary proteins that bind tannins this enables them to feed on tanniniferous plants (Robbins etal, 1991). By contrast, grazers such as sheep and cattle do not possess tanninbinding proteins (Austin etal, 1989 Robbins etal, 1991), and neither do mixed feeders such as goats (Distel and Provenza, 1991). Rat and mouse saliva also contain proline-rich proteins that bind tannins. In human saliva, about 70% of total protein is rich in proline (Fig. 11.9) (Mehansho etal, 1987). 

Nowadays web information is often delivered by means other than the simple (static) web browser. RSS feeds (a new format for notifying new content at a web site), which stands for really simple syndication, and is a new way of getting news in general, has recently been introduced for the American Chemical Society (http //www.acs.org) journals (see http //pubs.acs.org/alerts/rss/index.html). The information is not fed directly into a browser, but into a news aggregator such as FeedDemon (http //www.feeddemon.com). 

One way to do this is to manually adjust the feed split in Tl until (2ri is equal to Qc -This can be automated by going to Flow Sheeting Options on the Data Browser window and selecting Design Spec. This is similar to the Design SpecA ary in the column blocks,... 

Once you are happy with the previous runs, change the input conditions (using the same flowsheet) to look at different feed conpositions and different fraction vaporized. There are at least two ways to input new data. (1). Left-click on the block for the flash. Go to Data in the menu and left-click on input. Put in the desired numbers using the or buttons (not Next button) to move to different screens. (2) Go to Data in the menu and click on Streams. Click on the or button until you get the Stream (Material) Input-Data Browser. Change the data as desired. Try feeds that are 10, 30, 50, and 70 mol% ethanol and vary vapor fraction. 

Data Management and Visualization all data collected from the calculations is then again processed to condense repeated or reusable results. These results are then compared with existing ones feeding a results history data base. All results are then presented in a web-based interface, independent of platform or operation system, where all results can be viewed on an open-source format through an open-source web plug-in in any Internet browser. 

After entering feed stream data, the next step is to enter data needed in the decanter block. Clicking on Blocks and DECANTER and Input on the left-hand side of the Data Browser opens the window shown in Figure 3.56. The first page tab is Specifications, on which operating pressure and another one decanter specification need to be specified. We select the... 

Browsers (Br) feed predominantly on dicotyledonous plants, whereas mixed feeders (MF) feed on both grass and dicotyledonous plants, depending on the availability. The best function obtained to discriminate between both groups involves only two variables, JMC (relative maximum width of the mandibular angle) and MZW (relative muzzle width), but their combined representation does not support a good discrimination.

Under Properties, Specifications, select the base property method. Since these components are liquids, NRTL thermodynamic package is the most convenient fluid package. Install CSTR reactor under Reactors in the model library, and connect inlet and exit streams. Specify the feed stream conditions and composition. Input the reactor specifications double click on the reactor block. The reactor Data Browser opens. Specify an adiabatic reactor and the reactor volume to 4433 liters the value obtained from hand calculations (Figure 5.11). Add the reactions to complete the specifications of the CSTR. Choose the Reactions block in the browser window and then click on Reactions. Click New on the window that appears. A new dialog box opens enter a reaction ID and specify the reaction as Power Law. Then click on Ok. The kinetic data are very important to make Aspen converge. Mainly specifying accurate units for pre-exponential factor A, is very important (see the k value in Figure 5.12). The value MUST be in SI units. 

The process flow sheet for a PFR in Aspen Plus is constructed in the same way as previous examples. In the data browser, specify the feed stream properties. Specify inlet reactions stoichiometry and parameters as shown in Figure 5.48 for the first reaction. For the thermodynamic data, Peng-Robinson is selected. The reactor is considered isothermal. The process flow sheet and stream property table are both shown in Figure 5.49.
