Equipment installation/operation

Equipment installation, operation, preventive maintenance, and test instructions... 

Modification of Equipment. (/) Install equipment that produces minimal or no waste. 2) Modify equipment to enhance recovery or recycling options. (I) Redesign equipment or production lines to produce less waste. (4) Improve operating efficiency of equipment. (5) Maintain strict preventive maintenance program. 

Unit layout as installed is the next step of preparation. This may take some effort if analysts have not been involvea with the unit prior to the plant-performance analysis. The equipment in the plant should correspond to that shown on the PFDs and P IDs. Wmere differences are found, analysts must seek explanations. While a hne-by-line trace is not required, details of the equipment installation and condition must be understood. It is particularly useful to correlate the sample and measurement locations and the bypasses shown on the P IDs to those ac tuaUy piped in the unit. Gas vents and liquid (particularly water-phase) discharges may have been added to the unit based on operating experience out not shown on the P IDs. While these flows may ultimately be small within the context of plant-performance an ysis, they may have sufficient impact to alter conclusions regarding trace component flows, particularly those that have a tendency to build in a process. 

Sampling locations for the unit test should be readily and safely accessible. The sample gatherer should be able to easily access the sample point. An isolation valve should be installed at the location. If a blind is installed, this should be modified in advance of the test. The sample locations shown on the P IDs must be compared against the actual locations on the equipment. Experienced operators may provide insight into the suitability of the location in question. 

Is equipment currently installed, operated, and maintained as designed ... 

Ambient temperature, altitude and atmospheric conditions at the place of installation of electrical equipment are considered to be the service conditions for the equipment to operate and perform its duties. All electrical equipment is designed for specific service conditions and variations may influence its performance. Below we analyse the influence of such non-standard service conditions on the performance of equipment and the required safeguards to achieve its required performance. 

The problem of eeonomie justifieation for the required investment is a matter that depends on the individual refinery situation. However, it is almost eertain that more refiners will be installing sueh equipment in the future. The ability of the equipment to operate satisfaetorily has been amply demonstrated and this will inerease the refiner s desire to eonsider and use flue gas expanders for FCC installations (Figure 4-55). For typieal sizes, refer to Figure 4-56. 

UltrafiUration is a preferred alternative to the conventional systems of chemical flocculation and coagulation followed by dissolved air flotation. Ultraflltration provides lower capital equipment, installation, and operating costs. 

One complete set of the installation, operating, and maintenance instructions, shall be packed in the boxes or crates and shipped with the equipment. 

If it is extremely uneconomical to design at this point, then proper vacuum control must be installed. However, this is not the usual approach to the design. If the equipment can operate alternately under vacuum or positive pressure, it must be designed for the worst or controlling condition. 

Plant engineering is that branch of engineering which embraces the installation, operation, maintenance, modification, modernization, and protection of physical facilities and equipment used to produce a product or provide a service. 

This chapter introduces the basic items of design and specification for the principal systems and components of an electrical industrial installation. Electrical supply systems are discussed with regard to interface with the supply authorities and the characteristics. Salient features of switchgear, transformers, protection systems, power factor correction, motor control equipment and standby supplies are identified and discussed together with reference to the relevant codes of practice and standards. The equipment and systems described are appropriate to industrial plant installations operating at typically 11 kV with supply capacities of around 20MVA. 

The fault level at the point of supply to the installation requires consideration. The minimum fault level which can occur will affect the operation of the installation, particularly with regard to voltage regulation when starting motors, while the maximum fault level will determine the ratings of equipment installed. All supply systems develop with time, and the switchgear and other equipment installed at an installation must be chosen to be suitable if the external supply system expands. 

Failure analysis statistics have consistently shown that many machinery components failures can be directly attributed the equipment being operated outside of design parameters or unintended conditions. Most failure analysis and trouble-shooting activities are usually post-mortem and commence after installation and start-up of the equipment. The maintenance phase is now in motion, and failure analysis and trouble-shooting is now an integral part of that phase. 

In addition to the product, the designer, equipment installer, user, and all others involved in production should all consider performing a risk assessment and target in the direction of perfection. The production is reviewed for hazards created by each part of the line when operating as well as when equipment fails to perform or complete its task. This action includes startups and shutdowns, preventative maintenance, QC/inspection, repair, etc. 

Increased demand for softened MU, perhaps caused by an increase in plant capacity without increasing softener capacity installed, or the use of additional steam for processing so that the return of condensate is diminished. Here a larger plant is required. If the existing plant is not too old, a second identical unit usually is installed and the equipment is operated as duty/standby, with water-meter countdown crossover and immediate regeneration of the out-of-service unit. 

The recent US National Fire Code covers all aspects of equipment, installation and safe operational practices necessary for bulk oxygen storage at consumer sites. 

Qualification of the installations to document the ability of the equipment to operate the process described in Section 6.2.2... 

To ensure that equipment is fit for its intended purpose, there is a series of qualifying steps that the analyst or vendor should apply to analytical instrumentation (3,4). Equipment can be evaluated through a series of tests or procedures designed to determine if the system meets an established set of specifications governing the accepted operating parameters. The successful completion of such tests justifies that the system operates and performs as expected. There are four components of instrument qualification design, installation, operational, and performance. 

Instrument qualifications are the tests that are performed after the equipment is installed for use in a laboratory. Instrument qualifications include installation qualification, operational qualification, and performance qualification. These tests verify that the equipment is installed, operates, and performs according to the manufacturer s specifications. Each of these types of qualifications is defined in more detail in the following sections. 

The manufacturer often creates an instrument qualification plan and provides installation, operational, and performance qualifications to be executed in the customer s laboratory. The company using the equipment must determine if the manufacturer supplied instrument qualifications is comprehensive enough to be sure that the equipment is installed, operating, and performing correctly. If they feel it is not, they may choose to perform more tests themselves. 

Indeed, the need for capital investment in a CMO may not have been originally anticipated or planned for and may impact on the whole decision making process. Additional costs and time need to be set aside for training and equipment validation, e.g. PQ/IQ/OQ (process qualification/ installation qualification/ operational qualification), and if this includes equipment with radically different operating principles than currently available on site then additional costs will be required for equipment-specific operating personnel and training. 

The purchaser will specify whether the installation is indoors (heated or unheated) or outdoors (with or without a roof), as well as the weather and environmental conditions in which the equipment must operate (including maximum and minimum temperatures, altitude, unusual humidity, and dusty or corrosive conditions). The unit and its auxiliaries shall be designed for operation under these specified conditions.
