The difference between the P95 scenario and the base case was adopted for the owner's contingency.

the equipment capital cost for major process equipment found inside many process plants. Furthermore, a comparison to Aspen Capital Cost Estimation (ACCE) software package will be done as well. A major factor in deciding whether or not to build or expand any chemical/process plant is the capital cost estimation.

C = F * Sum (C_e) 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. Lang factor is 3.1 for solid processing plant and 4.74 for fluids processing plant. Better estimate can be made when the different factors are used for corresponding equipment.

Abstract. Once individual equipment costs are known from either manufacturers' price quotations or estimating charts as discussed in the previous chapter, they can be utilized to form preliminary total plant cost estimates. A suggested sequence for obtaining such estimates is as follows: 1. Prepare a flow sheet for the process or operation to ...

Capital Costs. Levels of Capital Costs . As illustrated by Figure 1, this methodology defines capital cost at five levels: BEC, EPCC, TPC, TOC and TASC. BEC, EPCC, TPC and TOC are "overnight" costs and are expressed in "base- year" dollars. The base year is the first year of capital expenditure.
Cost estimating - A predictive process used to quantify, cost, and price the resources required by the scope of an asset investment opt ion, activity, or project .
Capital cost comprised the largest fraction of the overall cost for both processes (Table 4). The centrifuge cost of $520,000 was higher than the primary depth filter holder cost of $53,000. However, when this cost was annualized over 10 years, the overall capital cost was similar for both processes at this scale.
Capital estimation is, therefore, crucial at all design steps, from early stages and throughout the development of the project until the plant is finally commissioned and ready to go online. Capital cost estimation of biorefineries follows similar patterns to those of any new chemical processing plant. 1.1 Background

a capital cost of approximately $200M. The scope of this current estimate was restricted to the Kundip resource and considered just two metallurgical domains –the low copper oxide and the high copper sulphide. This greatly simplifies the process design. In addition, as the processing will be sequenced it allows for a

attention to copper prices that will allow us to highlight, in a practical instance, the main features of our methodology. Copper prices are highly volatile and depend on many external factors: existing copper stocks and contracts, deposits discoveries, the local and world-wide economic environment and technological innovations, for example.

Capital cost assessment is an integral part of process design when building or expanding a chemical process plant. It is required to provide project analysis and evaluation, to select among alternative designs, to plan the appropriation of funds and to serve as a basis for project cost control.
