The capital costs associated with purchasing, building, and starting up any chemical plant can be estimated with methods discussed in previous and later sections. Study estimate (factored estimate). It is good practice to include design factors for safety throughout the process. Usually, the above method is used as a preliminary estimate. For example, if water or electricity are being utilized from the main grid, and infrastructure needs to be expanded to accommodate the chemical plant's addition to these systems, these costs are considered OSBL because they are not directly associated with elements between the input and output of the chemical plant. It is required to provide project analysis and evaluation, to select among alternative designs, to plan the appropriation of funds and to. Usually, contingency charges are billed to the parent organization, or of the design is done by a contractor to the contracting organization directly at the start of the project, rather than asking for increased funding mid-project. Capital Cost Estimator - DWSIM - Chemical Process Simulator Cost Estimation Documents for Chemical Process Engineers The two main methods of project financing are debt and equity financing. Any appropriate date may be entered; the CE index entered should correspond to that date; the index must be extrapolated for dates beyond the most recently available value. New York: Halsted Press; 1985. In many cases, an estimator must use considerable judgment in preparing the estimates. Equipment Costs for Plant Design and Economics for Chemical Engineers Cost curves can be used as preliminary estimation of equipment costs if updated cost data is not available. OSBL costs are initially estimated as a percentage of the ISBL costs. OSBL (Outside Battery Limits), or off-site costs, are still an important component of the plant cost, but deals with calculating costs associated with off-site developments that require the plant to run. The discussion of project financing is centered on some quantitative measures that are often used to understand the growth and profitability of a company. Correlations for constants can be found in Towler's Chemical Engineering Design (Towler and Sinnott, 2013).

But it must be noted that for chemical plants of different processes, the individual factors that affect working capital can have large variance, and the aforementioned estimate will not work well for all situations. There are also other indices for building the plants offsite. Lang proposed capital cost equipment by given equation: C is the total capital cost, F is the installation factor also known as Lang factor, and C_e is the cost of major equipment. Plant Costs Estimation. The Association for the Advancement of Cost Estimating International (AACE International) classifies five types of estimates of capital cost. The capital costs associated with purchasing, building, and starting up any chemical plant can be estimated with methods discussed in previous and later sections. The working capital turnover is a metric that is used to determine how efficiently the working capital is managed. The other extreme is utilizing an existing, underused site with no solids handling requirement, when fabricating a low-volume specialty chemical. hKoFs\qO>Hriu7(K%}VM`|of;|NHT!SB):1y.'T@8dx,pZ` :yU;t%dOH%#9Wz6! 0000033753 00000 n Total Installed Cost = Total Equipment Cost (Purchase Cost) x f The three factors (f) for each type of plant being: Solid process plant = 3.10 Solid-fluid process plant = 3.63 Fluid process plant = 4.74 This cost includes design, site remediation, purchasing process equipment, developing infrastructure, and contingency charges, and includes the raw material costs as well as labor. Analysis, Synthesis and Design of Chemical Processes (Turton) Plant Design and Economics for Chemical Engineers (Peters) 0000006410 00000 n Project Management for Construction: Cost Estimation Many variations of the factorial method exist as different assumptions can be made which will determine the rigorousness and the accuracy of the estimate. Material factor, however, does not linearly scale with the installation factor since the transportation cost, labor cost, and fabricators cost does not scale with the material of the equipment. The expected return is a combination of the dividends the company pays and the growth of the company's stock price. He identified three process plant types, which are solid processing plant, fluids processing plant, and mixed fluids-solids processing plant. This type requires data such as preliminary material and energy balances and major equipment items.
