Process selectivity

There are many different routes to organic chemicals from biomass because of its high polysaccharide content and reactivity. The practical value of the conversion processes selected for commercial use with biomass will depend strongly on the availabiUty and price of the same chemicals produced from petroleum and natural gas. [Pg.28]

Sihcon dioxide layers can be formed using any of several techniques, including thermal oxidation of siUcon, wet anodization, CVD, or plasma oxidation. Thermal oxidation is the dominant procedure used in IC fabrication. The oxidation process selected depends on the thickness and properties of the desired oxide layer. Thin oxides are formed in dry oxygen, whereas thick (>0.5 jim) oxide layers are formed in a water vapor atmosphere (13). [Pg.347]

Process selectivity indicates the preference with which the process removes one acid gas component relative to or in preference to another. For example, some processes remove both hydrogen sulfide and carbon dioxide, whereas other processes are designed to remove hydrogen sulfide only. Thus it is important to consider the process selectivity for hydrogen sulfide removal compared to carbon dioxide removal, ie, the carbon dioxide-to-hydrogen sulfide ratio in the natural gas, in order to ensure minimal concentrations of these components in the product. [Pg.209]

Other factors which have a significant influence on process selection iaclude absolute quantity of sulfur present, concentration of various sulfur species, the quantity and concentration of other components ia the stream to be treated, quantity and conditions (temperature and pressure) of the stream to be treated, and, the location-specific environmental regulations governing overall sulfur recovery and allowable sulfur dioxide emissions (3). [Pg.209]

Process Selection The preceding sec tions present many process cycles and their variations. It is important to have some gmdelines for design engineers to narrow their choice of cycles to the most economical for a particular separation. Keller and coworkers [Keller et al., gen. refs.] have presented a method for choosing appropriate adsorp-... [Pg.1548]

A study of gas treating can be very confusing because so many processes exist. The discussions in this chapter attempt to explain the differences among some of the most popular processes. Understanding of the different processes will aid in process selection. [Pg.188]

Figure 1 should be used in the process selection as one of the important parameters. The processes listed within the graph are in preference order. [Pg.188]

To describe a continuous process on a standard basis, always choose a unit of time or a consistent flow rate per-unit-of-time basis. For batch processes, select a unit-weight basis on the basis of a single batch. [Pg.372]

For aromatics production, similar considerations apply. Maximum yields of xylenes and other heavy aromatics can be obtained in cyclic units, but, again, at somewhat higher investments. The process selection, thus, again requires the balancing of process credits versus debits for the specific application. For light aromatics (benzene-toluene) production, however, the situation tends to favor a... [Pg.58]

Show that a DEA unit is an acceptable process selection. [Pg.192]

Tailing peaks or longer than expected elution volumes are sometimes caused by low solubility of the protein in the mobile phase. Using a trial-and-error process, select the proper pFf and ionic strength to address this problem. Detergents such as sodium dodecyl sulfate (SDS) are sometimes helpful but, because they change the conformation of many proteins and are difficult to remove from the column should be used only if other methods fail. [Pg.90]
