VAPOR CONDENSER

With free air the cooling medium you use the least water, evaporated in the air stream. You save the cost and pumping of large volumes of condens ing water. L '
Air-vapor subcooling reduces mix ture evacuated from the system, sav ing in the operation of steam ejector or vacuum pump. This air-cooled condenser givej you more capacity than other types at a substantial saving of steam and power. Water supply, scaling treatment and disposal problems are eliminated. You get pure condensate, an im proved product; often make a profit on recovery of residues now wasted. There can be no contamination of your product at any time; it never touches raw water. Condensing, of water, of solvents or of your product, is simplified; you have one, compact,

Just Like α Business Economic evaluation can be said to have the advantages and dis advantages of a n entire business endeavor. Cost engineers face daily the major decision point of most industrial concerns—the capital in vestment. They deal in the fore casts, planning, a n d control neces sary to operation of a business. Because they may be the last stopping point for a n investment evaluation before approval, they are subject to many of the same pressures to get results fast so that a decision can be made. However, compared with owning a business of your own, the existence of such a department as part of a chemical company does improve the j o b security and reduce the risk of failure. Cost engineering studies provide a broad background in the company. T h e economic evaluation review of major new projects before approval informs the engineers on all parts of the company as each part brings in new projects. A similar study may also be the first hurdle for research projects, when they have reached the applied stage, so that cost engineers gain familiarity with the more distant future as well. Jobs m a y involve, many personal contacts a n d instruction from almost every staff a n d line department in the company, in the process of obtaining proper forecasts. There is n o better place to see many of the company problems—sales, pro duction, traffic, purchasing, account ing, etc. Placement in the Organization

Depending on the size of the com pany, economic evaluation groups may be utilized in many parts of the organization. A recent presenta tion indicated eleven possible re porting relationships for such a group (Stokes, C. Α., "Organization & Coordination of the Economic Evaluation Function," A I C h E Phil adelphia Meeting, June 27, 1958).
