For more than 46 years, chemical process industries (CPI) professionals — engineers, managers, and technicians — have used Chemical Engineering’s Plant Cost Index (CEPCI) to adjust process plant construction costs from one period to another. This index — rather, indexes, as it consists of a composite index and eleven sub–indexes — has received such wide acceptance that it has even been written into construction–contract, cost

Cost index used for 1999 = 109. Cost index used for 2009 = 121. 11.1. CSTR-1: Purchased equipment cost = Ce = CS n. Cost constant = C = $ 31000. Area of column = S = 5m 3. Index = n = 0.40. Ce = CS n. Ce = CS 0.40 = 31000 (5) 0.40. Ce = $ 59013.27. Ce (2009) = 59013.27 x (121/109) = $ 10005. 11.2. Distillation column D-1: Number of plates = 5. Reflux ratio = 2.

2019-3-20 Based on an average of the monthly values for the Chemical Engineering Plant Cost Index (CEPCI), the annual average value for 2018 is 603.1. The total represents a 6.3% rise over the annual value from the previous year. The percentage gain from 2017 to 2018 is greater than the increase from 2016 to 2017, which was 4.8%.

A conunonly used index is the Marshall and Swift (M S) equipment cost index published in the monthly magazine Chemical Engineering. For atmospheric pollution control equipment, the Vatavuk cost index may be used (Vatavuk, 1995). It is not recommended to use cost indices if the updating period exceeds ten years. [Pg.304]

2014-2-1 The chemical engineering plant cost index correlates well with macroeconomic factors. Current oil prices and current and past interest rates are the independent predictors. These predictors may also reflect market conditions, inflation and unit labour costs. The correlation is accurate within 3% over the period 1958–2011 and 1% over 2004–2011.

2015-1-5 Marshall Swift Equipment Cost Index was created to make comparisons between two former quarters or years. Index comparisons are developed by dividing the index for the date for which a cost is desired by the index for the date of the known cost and multiplying the resulting factor by the known cost. The Marshall Swift Equipment Cost Indexes are based on a national average for 47

2010-12-16 This paper studies the problem of processing supergraph queries, that is, given a database containing a set of graphs, find all the graphs in the database of which the query graph is a supergraph. Existing works usually construct an index and performs a filtering-and-verification process, which still requires many subgraph isomorphism testings. There are also significant overheads in both ...

Graph theory assumes that cost alone governs connected traversal; if node A is connected to node C, then it is always possible to traverse the graph from A to C, provided the cost is paid. Meanwhile, chemically, a reaction must obey its stoichiometry ( i.e. all reactants must be present for a reaction to occur), and there must be a non-negative ...

2021-2-17 Tables giving values of this factor, for chemical plants and equipment, can be found in the literature (Happel, 1958; Bauman, 1964). If the total cost is plotted against capacity on a log-log graph, a straight line will be obtained with a slope equal to cost-capacity factor.

2005-1-25 In this paper we present an algorithm for the generation of molecular graphs with a given value of the Wiener index. The high number of graphs for a given value of the Wiener index is reduced thanks to the application of a set of heuristics taking into account the structural characteristics of the molecules. The selection of parameters as the interval of values for the Wiener index, the ...
