The proflt-to-investmentratio (PIR) may be defined in many ways, and is most meaningful when deflated and discounted. On an undeflated and undiscounted basis, the PIR may be defined as the ratio of the cumulative cash surplus to the capital investment. This indicates the return on capital investment of the project, is simple to calculate, but does not reflect the timing of the income/investment in the project. 

As can be seen from this analysis, the natural gas feedstock and capital charges amount to over 93% of the total production cost before return on investment. Therefore, energy consumption and capital investment are the key factors in determining ammonia production profitabiUty. 

Capital investment, capital costs, operating costs, return on investment, and energy conservation have all been discussed (6). In the economic analysis, the speed of each type of pump considered is normalized to 1 m /s as a common basis. 

The most common approach to fixed cost estimation iavolves the use of a capital recovery factor to give the annual depreciation and return on capital. This factor typically is between 15 and 20% of the total capital investment. Property taxes are taken as 1—5% of the fixed capital and iasurance is assumed to be 1—2% of the fixed capital. If annual depreciation is estimated separately, it is assumed to be about 10% of the fixed capital investment. The annual iaterest expense is sometimes neglected as an expense ia preliminary studies. Some economists even beHeve that iaterest should be treated as a return on capital and not as part of the manufactufing expense. 

Capital Investment. Erom the viewpoint of a project, all of the capital that must be raised is external capital. Equity capital is the ownership capital, eg, common and preferred stocks or retained cash, whereas debt capital consists of bonds, mortgages, debentures, and loans. Nearly all investment involves a mixture of both types so as to maximize the return on investment (21). The debt ratio (debt/total capital) for the chemical industry is typically over 30%. Because financial details are not well known during the preliminary phases of project analysis, the investment is viewed simply as the total capital that must be expended to design and build the project. 

Possible numerators include the gross income net pretax income net after-tax income gross profit, ie, gross income minus book depreciation cash flow or net income. An average return value is selected by defining a typical or mature proof year as the basis of calculation. The denominator can be the original total investment, depreciated book-value investment, lifetime averaged investment, or fixed capital investment. 

Ethane feed gives the lowest cost of production and the lowest capital investment. As the feeds become successively heavier, cost of production increases as well as the capital investment required. Depending on the cost of feedstock and the value of the co-products, processing heavier feedstocks can lead to lower returns on investment. Table 13 shows the effect on capital investment for various feedstocks as well as for a range of capacities. 

Example 3 Sensitivity Analysis The following data describe a project. Revenue from annual sales and total annual expense over a 10-year period are given in the first three columns of Table 9-5. The fixed-capital investment Cfc is 1 million. Plant items have a zero salvage value. Working capital C c is 90,000, and the cost of land Ci is 10,000. There are no tax allowances other than depreciation i.e., is zero. The fractional tax rate t is 0.50. For this project, the net present value for a 10 percent discount factor and straight-line depreciation was shown to be 276,210 and the discoiinted-cash-flow rate of return to be 16.4 percent per year. 

The return on capital investment did not justify a power recovery system unless more tlian several tliousand horsepower was recovered. 

Recently, there has been a substantial shift in conditions and user attitudes. With increasing cost of power, the return on capital investment has vastly improved. A more favorable regulatory climate and changes in attimde of utility companies toward remrning electricity to tlieh grid have made novel power producing schemes practical and attractive. 

Capital investments can also be selected on the basis of other measures of performance such as return on investment, internal rate of return, and benefit-cost ratio (or savings-to-investment ratio). Flowever, care must be taken in the application of these methods, as an incremental analysis is required to ensure consistent comparison of mutually exclusive alternatives. Also, rather than requiring a separate value to be calculated for each alternative, as in the case of the life-cycle cost method, these other methods incorporate the difference between two mutually exclusive alternatives within a single measure. For example, the net benefits measure directly pressures the degree to which one alternative is more economically desirable than another. 

While this example is constructed to be an extreme case, It illustrates the importance of not being misled that a long-lasting stream of returns necessarily means that a capital investment will be profitable. Returns from energy savings to be received far in the future will have a low present value unless some mechanism works persistently to raise future energy prices at a rate that is commensurate with, or exceeds, the discount rate. 

The chemical and petrochemical industries are highly capital intensive and this has two important implications for the plant designer. Before the expenditure for any plant is approved, a discounted cash flow (DCF) return on capital invested is projected (Section 9.1). The capital cost of the plant is a key factor in deciding whether the DCF return is above or below the cut-off value used by a company to judge the viability of projects. Thus, there is always strong pressure on the materials engineer not to overspecify the materials of construction. 

Return on investment ROT) is the ratio of profit to capital investment ... 

Economic analysis can determine the discounted profitability criteria in terms of payback period (PBP), net present value (NPV), and rate of return (ROR) from discounted cash flow diagram, in which each of the annual cash flow is discounted to time zero for the LHS system. PBP is the time required, after the construction, to recover the fixed capital investment. NPV shows the cumulative discounted cash value at the end of useful life. Positive values of NPV and shorter PBP are preferred. ROR is the interest rate at which all the cash flows must be discounted to obtain zero NPV. If ROR is greater than the internal discount rate, then the LHS system is considered feasible (Turton et al., 2003). 

Figure 2.2 shows the cash flow pattern for a typical project. The cash flow is a cumulative cash flow. Consider Curve 1 in Figure 2.2. From the start of the project at Point A, cash is spent without any immediate return. The early stages of the project consist of development, design and other preliminary work, which causes the cumulative curve to dip to Point B. This is followed by the main phase of capital investment in buildings, plant and equipment, and the curve drops more steeply to Point C. Working capital is spent to commission the plant between Points C and D. Production starts at D, where revenue from sales begins. Initially, the rate of production is likely to be below design conditions until full production is achieved at E. At F, the cumulative cash flow is again zero. This is the project breakeven point. Toward the end of the projects life at G, the net rate of cash flow may decrease owing to, for example, increasing maintenance costs, a fall in the market price for the product, and so on.

The return on investment is the expected profit divided by the total capital invested. This is the percentage return that an investor may expect to eventually earn on his money. Since the federal corporate income tax rate is around 48% on all profits, it must be stated whether the profit is the before- or after-tax earnings. 

Often, as in the case of the return on the investment, expenses not incurred directly in the design and construction of the plant are excluded when the payout period is calculated. If the only prestartup expense considered is the fixed capital investment, a payout time of 3-5 years is reasonable. A time longer than this is considered unacceptable. 

Cross-subsidies occur, as the company is given incentives to expand its production activity even in low-profit productions (for example, producing brand name generics), as it can recover the authorized rate of return for the entirety of the capital invested. 

Cash flows used in calculating net present value (NPV) and internal rate of return (IRR) for a typical capital investment project. 

Like all major capital investment projects, the financial case is based on the financial return, however measured, and the availability of finance. 

The return on investment is derived from the ratio of the total capital invested and the turnover to profit ... 

Returning to the main theme - cost - money is the driving force behind much capital investment. In this chapter a summary of the economics behind the use of titanium has been provided. The savings indicated were based on interviews with end-users.
