Troubleshooting tools

Temperature sensing points at various points along the tower shell are often a useful troubleshooting tool. Many... [Pg.69]

A colloid fog will scatter a beam of light. This is called the Tyndall Effect and can be used as a troubleshooting tool. [Pg.305]

Polymer solution viscosity is a troubleshooting tool for polymer processing. Solution viscosity may be utilized to determine the degradation of some polymers via a decrease in molecular weight, particularly for polymers that can be hydrolyzed by water. It can be a troubleshooting tool because the results can be obtained quite rapidly. Intrinsic viscosity is commonly known as IV when referring to polyesters. It is applicable, however, to any polymer that is soluble at moderate concentrations in a good solvent [2]. [Pg.68]

Most of the mentioned troubleshooting tools will work with other silica-based columns. With normal-phase columns, you obviously need not worry about bonded-phase removal, but silica still dissolved at high pH and high salt concentrations. Polar materials like some proteins adhere very tightly and require... [Pg.84]

I n addition to learning about the many common problems and troubleshooting techniques for Windows, you should know about the different resources that Microsoft provides with Windows to troubleshoot Windows. These resources are the best to use if you have no other troubleshooting tools available. They can also be used as a starting point for troubleshooting a computer. The built-in Windows tools that the A+ exam tests you on, include ... [Pg.784]

Kister says that d/b plots are primarily used when there is a tight spec, on a nonkey component or a concern about the distribution of an intermediate key component. His book shows d/b curves for various feed stage locations on a plot of the mole ratio of a reference component in the distillate to the bottom product, versus the relative volatility of each component to this reference component. This plot is made on log-log paper. The optimum feed produced a curve closest to linear. The d/b plot is suggested as a troubleshooting tool in the subsection of the Troubleshooting section, Fractionation Operating Problems. ... [Pg.67]

Time permitting, the more lengthy Smith-Brinkley Method (Reference 19) could also be used as an analysis troubleshooting tool. [Pg.334]

Zeta potential - a measure of the charge on the solids, as opposed to the PCD which measures charge in the water phase a useful troubleshooting tool when retention aid performance changes. [Pg.50]

Fault trees are excellent troubleshooting tools. Properly used, they can aid in determining what failed or what was less than adequate in a particular system. Fault tree analysis is a tool used to determine how and why the particular failure occurred. [Pg.115]

Another useful troubleshooting tool is the infrared thermometer. Figure 11.2 shows an example of a handheld infrared thermometer. [Pg.768]

Computers can function as powerful troubleshooting tools. Advanced technology systems, coupled with add-on interface cards and applications software, provide a wide range of testing capabilities. Computers can also be connected to many different instruments to provide for automated testing. There are two basic types of stand-alone automated test instruments (KTEs) functional and in-circuit.

Excessive internal pump bypassing (worn wear rings) or external pump bypassing (through a discharge to suction recycle line) also takes more horsepower. A useful troubleshooting tool for pump motor problems is a permanently mounted ammeter. [Pg.128]

Gas oil left in resid will often have a value equivalent to fuel oil. Gas oil recovered for FCCU feed will have a value equivalent to crude. It follows, then, that every barrel possible ought to be boiled out of the vacuum tower bottoms. The best troubleshooting tool for judging overall vacuum-tower performance is to vacuum distill off in the lab the 1,000°F- gas oil in the resid. Based on plant data, the following rules of thumb may then be applied ... [Pg.146]

FIQURE 25-8 Beta Scan plots are a powerful troubleshooting tool. [Pg.494]

FCC Network, The, http //www.thefccnetwork.com/ (accessed July 23, 2010). An online network covering fluid catalytic cracking and related petroleum refining processes. Registrar ion is free, and includes access to a monthly newsletter, technical papers and catalyst reports, tips and techniques for troubleshooting, tools and strategies for FCC performance optimization, and submission of questions to an advisory panel. [Pg.489]

TG has been widely used to characterise compounded elastomeric materials in commercial [240] and military applications [235]. TG is a troubleshooting tool in the rubber industry [241]. Ohtake et al [109] have presented examples of such analyses with reference to faults that have actually occurred in industrial rubber components. Ramirez et al [242] have described TG studies of a wide range of (un)vulcanised elastomers and blends. In most... [Pg.182]
