Compounding investments

Solid-supported chemistry is very useful for the synthesis of larger series of compounds investments in the development of methods will be paid off by faster production through simple robotic methods.

As the market expanded globally and the capital cost per unit per volume decreased, many compounders invested in larger twin-screw extrusion systems, as discussed in Section 5.2.1 on twin-screw extrusion technology.

Suppose you have to meet an obligation to pay a bill of 10,000 in 5 years time. If you could be guaranteed a compound interest rate in your bank of 7% per annum (after tax) over each of the next 5 years, then the sum which you would have to invest today to be able to meet the obligation in 5 years time would be ... 

In the above example, the discount rate used was the annual compound interest rate offered by the bank. In business investment opportunities the appropriate discount rate is the cost of capital to the company. This may be calculated in different ways, but should always reflect how much it costs the oil company to borrow the money which it uses to invest in its projects. This may be a weighted average of the cost of the share capital and loan capital of a company. 

Anthraquinone dyes are derived from several key compounds, ie, dye intermediates. Production of these dye intermediates often requires sophisticated production processes and a large amount of investment in plant constmction. The competitiveness of final products, dyestuffs, depends on that of the intermediates, ie, quaUty, cost, and availabiUty. 

Aroma.tic-AUpha.tic Polyester Resins. Unlike most other classes of engineering plastics, which are made by only a few manufacturers, aromatic-aHphatic polyester resins are produced and compounded by several dozen firms (66). The aHphatic polyester resin marketplace is characterized by wide product differentiation and competition. Some firms make only a few hundred tons per year and presumably retain profitabiHty because of the avadabiHty of low cost monomer and the simplicity of the processes employed. Low investment and low manufacturing costs are possible even for smaH-volume operations. 

Let us suppose that 100 is invested at a nominal interest rate of 5 percent. We then compute the future worth of the investment after 2 years and also compute the effective annual interest rate for the following lands of interest (I) simple, (2) annual compound, (3) monthly compound, (4) daily compound, and (5) continuous compound. The following tabulation shows the results of the calculations, along with the appropriate equation to be used ... 

For this simphfied case the net present value (NPV) after n years with money invested at a required aftertax compound annual fractional interest rate i is given by the equation... 

Thus the requirement for the use of man-made drugs and dietary additives as veterinary medicines for the treatment of farmed animals is considerable and worth about 100 million pounds sterling annually in the UK ( 104 million in 1994j io jjjg investment in dietary additives such as vitamins, trace minerals, coccidiostats, pigmenters, enzymes and other probiotics to feed compounders in the UK is worth about 110 million, assuming an addition rate of 2.5 kg per tonne and a cost of approximately 3% of the total concentrate dietary cost (calculated from MAFF data, 1995). ° These data can be increased by a factor of about 10 when the compound feed produced within Europe is considered. 

Concentration and Composition The average concentration of organic compounds in a waste gas determines the applicability of the abatement method. Recovery methods usually require high inlet concentrations. They may need a concentrator prior to actual treatment, which increases the investment cost. 

In catalytic incineration, there are limitations concerning the effluent streams to be treated. Waste gases with organic compound contents higher than 20% of LET (lower explosion limit) are not suitable, as the heat content released in the oxidation process increases the catalyst bed temperature above 650 °C. This is normally the maximum permissible temperature to which a catalyst bed can be continuously exposed. The problem is solved by dilution-, this method increases the furnace volume and hence the investment and operation costs. Concentrations between 2% and 20% of LET are optimal, The catalytic incinerator is not recommended without prefiltration for waste gases containing particulate matter or liquids which cannot be vaporized. The waste gas must not contain catalyst poisons, such as phosphorus, arsenic, antimony, lead, zinc, mercury, tin, sulfur, or iron oxide.(see Table 1.3.111... 

In the selection of control equipment, the most important waste-gas characteristics are volumetric flow rate, concentration and composition of organic compounds in the waste-gas, waste-gas temperature and humidity, and rbe content of particulate matter, chlorinated hydrocarbons, and toxic pollutants. Other factors influencing the equipment selection are the required removal efficiency, recovery requirements, investment and operating costs, ease of installation, and considerations of operation and maintenance. The selection of a suitable control method is based on the fundamental selection criteria presented as well as the special characteristics of the project. 

This method, which is favored by many accountants today, takes into account the concept that money has a time value. This is because 2000 in 10 years time is not the same as 2000 now. Similarly, if a project earns 2000 in 10 years time this is not the same as 2000 spent now to help finance the project. If, instead of spending this 2000, it had been invested at compound interest, then in 10 years time it would have become a much larger... 

The selection of the discount factor depends on the financial policy of the business, but is usually 2-3 per cent above the current interest rates. Use of discounting methods will determine whether the project cost will produce a better return than by simply investing the capital involved at the highest compound interest rate or, if the capital cost has to be borrowed, whether the rate of return is much higher than the cost of borrowing. 

The relatively low capital investment associated with compounding machinery (usually less than 1 million for a line, compared with many millions for a conventional reactor), coupled with a processing need for small amounts of tailored materials, allows small and mid-sized compounding companies to take advantage of producing reactive polymers. 

Much effort has been invested into the search for monomeric compounds [86-90]. One of the few reliable indications for a base-stabilized monomeric complex involved the use of spectroscopic methods. The complexes 1 and 2 could be isolated and characterized below —20 °C with spectroscopic methods [91],... 

Investment.—We give an interesting illustration of a combined optimization and probability problem given by B. Boy. It is a trivial matter to show that an amount of money (1 + r) k, invested at the compound interest of r% over a period of h years will become a unit amount. 

As for a gate fee, estimates are difficult to give. Costs are dominated by the investment costs, which Akzo estimates at 25 million for a 50,000 tpa plant. There exists a large uncertainty in this estimate. For instance, if the feed also included brominated or fluorinated compounds, extra cleaning steps would be needed which would greatly enhance the investment. It is simply too early to give a good estimate of costs per toime for treatment.
