The cost of energy production depends on costs during the expected lifetime of the plant and the amount of energy it is expected to generate over its lifetime. The levelized cost of electricity (LCOE) is the average cost in currency per energy unit, for example, EUR per kilowatt-hour or AUD per megawatt-hour . [5]
Approximate chemical formula: ((K 2 O) 2 ⁄ 3 (Na 2 O) 1 ⁄ 3) • Al 2 O 3 • 2 SiO 2 • 9/2 H 2 O; Silica-alumina ratio: SiO 2 / Al 2 O 3 ≈2; Production. 3A molecular sieves are produced by cation exchange of potassium for sodium in 4A molecular sieves. Usage. 3A molecular sieves do not adsorb molecules whose diameters are larger than 3 Å.
Life-cycle cost analysis. Life-cycle cost analysis (LCCA) is an economic analysis tool to determine the most cost-effective option to purchase, run, sustain or dispose of an object or process. The method is popular in helping managers determine economic sustainability by figuring out the life cycle of a product or process.
Whole-life cost. Whole-life cost is the total cost of ownership over the life of an asset. [1] [clarification needed] The concept is also known as life-cycle cost (LCC) or lifetime cost, [2] and is commonly referred to as "cradle to grave" or "womb to tomb" costs. Costs considered include the financial cost which is relatively simple to ...
Lifetime value is typically used to judge the appropriateness of the costs of acquisition of a customer. For example, if a new customer costs $50 to acquire (COCA, or cost of customer acquisition), and their lifetime value is $60, then the customer is judged to be profitable, and acquisition of additional similar customers is acceptable.
Product lifetime. Product lifetime or product lifespan is the time interval from when a product is sold to when it is discarded. [1] Product lifetime is slightly different from service life because the latter considers only the effective time the product is used. [1]
Infobox references. 1,1-Dichloro-1-fluoroethane is a haloalkane with the formula C. 2H. 3Cl. 2F. It is one of the three isomers of dichlorofluoroethane. It belongs to the hydrochlorofluorocarbon (HCFC) family of man-made compounds that contribute significantly to both ozone depletion and global warming when released into the environment.
