Manufacturing designs

An aimual review of the worldwide catalyst industry identifies current technical and business trends within the catalyst industry and fists virtually aU industrial supported (and other) catalysts by manufacturers designations (3). Included are the applications for the catalysts, the composition, ie, active agents and support materials, and some physical properties. [Pg.193]

Mechanical seal manufacturers design their products to last 5 to 10 years. The majority of seals are designed for 40,000 hours of operating life. There are 8,760 hours in a year. This is approximately 5 years, running a pump at 24 hours per day, and 15 years for a pump running at 8 hours per clay. [Pg.183]

The manufacturing design range is a range of pressure within which the marked burst pressure must fail to be acceptable for a particular requirement as agreed upon between the rupture disc manufacturer and the user or his agent. [Pg.980]

The installation of mixers on long shafts in tall tanks may become a problem if whip of the shaft develops. To reduce this possibility, a bearing support in the bottom of the tank will hold the shaft steady. Lubrication is by the tank fluid. Therefore this has limited application if abrasive particles are present. Normally the manufacturers designs avoid this extra bearing. Sometimes a guide bearing is installed about midway in the tanks to steady the shaft at this point. Again it is preferable to avoid this, if possible, and the manufacturer should make recommendations for the installation. [Pg.307]

Some manufacturers design bags for use with relatively low-pressure air (i.e., 15 psi) instead of the normal 100 psi air. This allows them to eliminate the venturi tubes for clean-gas induction. Others have eliminated the separate jet nozzles located at the individual bags in favor of a single jet to pulse air into the outlet-gas plenum. [Pg.778]

Four elements of microchannel scale-up models will be described pressure-drop design, heat-transfer design, reactor design, and mechanical and manufacturing designs. [Pg.243]

An estimate of the amount of liquid held up in the packing under operating conditions is needed to calculate the total load carried by the packing support. The liquid hold-up will depend on the liquid rate and, to some extent, on the gas flow-rate. The packing manufacturers design literature should be consulted to obtain accurate estimates. As a... [Pg.615]

Staging parameters will vary according to manufacturer design layout (see Note 3). Specimen should be washed of all peripheral tissue to ensure that no irrelevant information is image captured. This can potentially confound the information content of the scan (see Note 4). Likewise, staging material should... [Pg.227]

Despite these amazing developments, time is still needed to prove and demonstrate low-cost, easy-to-manufacture designs and ancillary systems. It is expected that it will take several production cycles at low-to-medium volumes to gain experience, establish reliability, and achieve maturity. Over the next decade, automakers may be unwilling to commit to extensive production, since early designs could become obsolete before costs are fully recovered. The following section describes current... [Pg.38]

E° [equation (15.4)] is also referred to as the offset, the zero potential point, or the isopotential point, since theoretically it is defined as the pH that has no temperature dependence. Most pH electrode manufacturers design their isopotential point to be 0 mV at pH 7 to correspond with the temperature software in most pH meters. The offset potential is often displayed after calibration as an indication of electrode performance. Typical readings should be about 0 30 mV in a pH 7 buffer. In reality, E° is composed of several single potentials, each of which has a slight temperature coefficient. These potentials are sources of error in temperature compensation algorithms. [Pg.237]

The conversion of 2 to 3 was optimized at full scale in the VRT reactor. In addition to confirming the productivity, safety, product quality, and economic benefit of the process, the robustness of the process was also demonstrated. Finally, this pilot study provided the basis for a full-scale commercial manufacturing design specification. Having fixed the optimum residence time, the process was then transferred into a plant Fixed Residence Time (FRT) cyanation reactor which employed a fixed length of jacketed static mixer for commercial manufacture. This FRT was capable of producing 300 metric tonnes per year of 3, with the same purified step yield of 80% that was achieved in the laboratory capillary reactor. [Pg.225]

With the advance of civilization, the potters of Egypt very considerably extended tire range of their operations, and introduced into their various productions many important Improvements. Egyptian pottery, however, does not appear at any time or under any circumstances to have aimed at a high art-character. It was a manufacture designed for purposes of practical utility, and its decorations were held to be altogether. [Pg.751]

Mote Probably the most newsworthy, publicized incidents have stemmed from public and industrial dumping sites, covered in this summary under landfill leachate. A class of pesticides most commonly found in groundwater is ncmatocidcs. They arc particularly difficult because manufacturers design them to be both persistent and toxic. DBCP il,2-dibromo-3-chloropropane) is a representative nematocide. [Pg.1729]

Although there is a wide variety of cooling tower manufacturers, designs, and structural materials used, particular types of tower are often associated with specific industries. This may further concentrate the focus of survey questioning to center around potential problem areas specific to the industry in question. For example ... [Pg.269]
