Equipment classified

It should be remembered that these qualifications are required in the essential requirements. Their approval by a third party is obligatory for equipment classified in the categories II to IV... 

Appendix 8-B of the CCPS book is entitled, Example ofTest and Inspection Equipment and Procedures. This appendix covers minimum testing and inspection requirements of all classified equipment. Classified equipment is equipment identified in operational safety standards and governmental regulations. 

Table 3,2-4 lists the structures, systems, and major components of the plant and indicates the classification and, if "safety-related", the radionuclide control function of each. This correlation of equipment classified as "safety-related" to the radionuclide control function performed by each is also illustrated on Figure 3.2-2. The specific application of the classification process resulting in the indicated "safety-related" designations is discussed in Safety-Related Structures, Systems, and Components for the Standard MHTGR. (Ref. 6)... 

As discussed for the depropanizer, Aspen IPE prepares the Capital Estimate Report, MCB.ccp, which contains detailed listings of the items to be procured to install the equipment (classified in the areas of piping, instrumentation, electrical, structural steel, and insulation), estimates of the man-hours required for installation, estimates of the costs, and an installation schedule. Estimates for contractor engineering and indirect costs are listed as well. 

Each technique has advantages and disadvantages. Packed columns are flexible as the packing can be easily modified for optimisation of each recovery process, but they are best suited to small scale operations. Tray columns are used for large scale, low to medium flow rate applications involving non-corrosive materials. Spray systems are used almost entirely for applications where pressure drop is critical such as flue gas treatment. Types of equipment classified as spray columns include cyclone and venturi systems. Bubble column equipment is a low cost, low maintenance option however back mixing can occur which reduces the counter-current flows required for optimum absorption. 

P-29 Application of OSHA PSM and EPA RMP to the Compressed Gas Industry. This publications provides guidance to help owners and operators identify OSHA PSM and EPA RMP covered processes and equipment classified as covered processes. The guidance targets the compressed gas industry and discusses often overlooked, covered processes such as cylinder storage. The application of the regulations is illustrated with many examples of scenarios typically encountered by users and manufacturers (18 pages). 

What relationships are used to analyze the following pieces of equipment Classify these as equipment independent and equipment dependent. 

Types of equipment classified as spray contactors include countercurrent spray columns, venturi scrubbers, ejectors, cyclone scrubbers, and spray dryers. The use of spray dryers as absorbers is of particular interest in the removal of sulfur dioxide from hot flue gas (see Chapter 7). 

Process operations. The third source of process waste we can classify under the general category of process operations. Operations such as start-up and shutdown of continuous processes, product changeover, equipment cleaning for maintenance, tank filling, etc. all produce waste. 

A wide range of equipment is available for the control of emissions of solid particles. These methods are classified in broad terms in Table 11.1. ... 

The manipulator is equipped with a vertical movement to utilize the in-built magnification facilities that come with the image intensifier based imaging system to assist in inspecting and classifying a block. 

In MSIA Spectrum developed and manufactured commercial version of specialized instruments that may be classified like equipment for criminology. With the help of such equipment... 

Molybdenum hexafluoride is classified as a corrosive and poison gas. It is stored and shipped in steel, stainless steel, or Monel cylinders approved by DOT. Electronic and semiconductor industries prefer the cylinders equipped with valves which have Compressed Gas Association (CGA) 330 outlets. 

Equipment. Food freezing equipment can be classified by the method and medium of heat transfer used. High velocity air is the most... 

Although steeping cycles vary from maltster to maltster, they can be classified as a variation or combination of one of three processes, indicated A, B, and C. The choice of steeping procedures depends on equipment limitations, process or product specifications, and company tradition. 

Underwriters Laboratories 333 Pfingsten Road Northbrook, Id. 60062 Standards for Safety is ahst of more than 200 standards that provide specifications and requirements for constmetion and performance under test and in actual use of a broad range of electrical apparatus and equipment, including household appHances, fire-extinguishing and fire protection devices and equipment, and many other nongenerady classifiable items, eg, ladders, sweeping compounds, waste cans, and roof jacks for trader coaches. 

The general pieces of equipment used in grinding flake mica or mica concentrate into saleable mica products are hammer mills of various types, fluid energy mills, Chaser or Muller mills for wet grinding, and Raymond or WiUiams high side roUer mills. Another method is being developed, called a Duncan mill (f. M. Huber, Inc.), that is similar in many respects to an attrition mill. AH of these mills are used in conjunction with sieves, and all but some types of hammer mills incorporate air classifiers as a part of the circuit. 

Most Type A processes might be classified as chemical processes, whereas most Type B processes are classified as mechanical processes. Representative examples of both types of processes foUow. Type B processes tend to be promoted by organizations that seU and service equipment for producing microcapsules. Most Type A processes are not promoted by equipment manufacturers, but are developed and used by organizations that produce microcapsules. 

Classifiers can be grouped into horizontal current and vertical current types, or into mechanical, nonmechanical, sedimentation, and hydrauHc or fluidized-bed types depending on the design of the equipment. The available equipment, their sizes, capacities, and their uses are given in Table 5. 

The hydrocyclone, commonly referred to simply as cyclone, is a nonmechanical sedimentation-type classifier (2,6,10,27) (Fig. 7). It has no moving parts or power attachments directly connected to it. The hydrocyclone has become the workhorse of most mineral processing operations because of its simplicity, short residence time, compactness, and low cost of operation. It is, however, characterized by lack of sharpness of separation. Equipment... 

Several nontechnical factors can significantly affect the results of a nondestmctive inspection. Many of these are classified as human factors (1,2,17). Operator experience affects the probabiUty of detection of most flaws. Typically, an inexperienced operator has more false rejects, known as Type II errors, than an experienced operator. A poor operator has few false rejects but is more likely to miss a defect in the inspection, known as a Type I error. Operator fatigue, boredom, or an unfavorable environment such as lighting, cold, or rain may further affect performance. Thus it usually is a good investment for the inspection company to assure that the operator environment is most amenable to inspection, that the equipment is suitable for the task, and that the operator is alert and well rested.
