Equipment efficiency

Performance based total productive maintenance aims to maximize equipment efficiency and time between overhaul, (overall performance effectiveness)...

Table 4-5 [10] summarizes dry dust particle separators as to general application in industry, and Table 4-6 and Figures 4-4 and 4-5 [42] compare basic collector characteristics. Figure 4-5 presents a typical summary of dust collection equipment efficiencies which have not changed significantly for many years except for specialized equipment to specialized applications. 

The work index, Wjr is basically an indication of ore hardness, but also includes equipment efficiency. The Bond method has been the mainstay of size reduction circuit. It still holds a value, specially for initial design calculations, and for simple checks on efficiency. 

Thus a single stage, NH= 1, corresponds to a solids temperature rise (or drop) equal to the average gas-solids temperature difference, as shown in the lower left-hand side of Fig. 10. On this basis, it is convenient to define equipment efficiency in terms of a unitary heat transfer stage ... 

The three unitary heat transfer parameters descriptive of equipment efficiency can now be redefined in terms of the above dimensionless integrals ... 

These indications lead to detailed investigations of the processes, e.g., from a financial perspective this might be revenue, contribution margin and earnings before interests, taxes, depreciation and amortization (EBITDA) of certain product groups and customers, cost analysis for specific processes, overall equipment efficiency or research and development costs. 

Utilities are also supporting the adoption and implementation of stricter building codes and equipment efficiency standards. The increas-... 

Appliance and equipment efficiency standards are having a notable impact on electricity demand in the United States. Standards have lowered national electricity use by 3%. A few energy efficiency measures, such as power-managed personal computers, have been widely adopted without financial incentives or much utility involvement. 

Note that combustion air is relatively inexpensive compared to fuel it is irrational to cut back on combustion air and waste fuel by inefficient burning. Also note that to operate fired equipment efficiently, we need to heat-prove it, or test to find the point of absolute combustion, on a regular basis, preferably at least once a day.

One can safely assume that the equipment efficiencies would improve and the unit costs would be cut, possibly by a factor of two in each decade. One can also assume that the cost of inaction will be much higher. For example, updating the old refineries and modernizing the global oil infrastructure would cost 3 trillion today This does not even include the costs of new oil... 

Currently, there is an enormous disparity between the most efficient and the least efficient processes and products in use today. A review of selected process and equipment efficiencies can provide a useful guide for establishing research and development priorities. 

Surface production facilities must be designed and operated to accommodate solids production. Produced solids collect in production equipment, separation equipment, and storage facilities in the regular routine of oilfield operations. The accumulated solids, which can total up to 20% of a vessel s volume during 1 year of operation, must eventually be removed before loss of equipment efficiency results. Before disposal of the removed materials, an effective process must be used to recover any crude oil bound to the solid material. 

D. Maintainability review This three pronged approach to improving equipment reliability is based on failure analysis to identify root causes, testing of equipment immediately after repair to ensure quality work was performed, and performance analysis of equipment to determine equipment efficiency rates and replacement intervals. This methodology uses predictive technologies. 

A new two-part, sprayable ceramic coating designed to protect metal surfaces on industrial equipment from wear, abrasion and corrosion is now available. Packaged in a reusable dualcartridge dispenser, Loctite Nordbak 7255 sprayable ceramic coating can be sprayed onto metal components to create smooth, low-friction surfaces that improve equipment efficiency. 

Safety of the reactor plants is relied upon the reactors inherent self-protection features and application of successive protective barriers, redundant systems and equipment, efficient safety systems. 

But the death machine had only sampled a vast new source of raw material the civilians behind the lines. It had not yet evolved equipment efficient to process them, only big guns and clumsy biplane bombers. It had not yet evolved the necessary rationale that old people and women and children are combatants equally with armed and uniformed young men. That is why, despite its sickening squalor and brutality, the Great War looks so innocent to modem eyes.
