An innovation is a direct-contact condenser mounted on the vapor body. A short piece of vertical pipe connects the vapor body with the condenser to minimize piping and pressure drop. This design also eliminates structural steel for support of a separate condenser. For cooling tower applications, the hotwell is elevated to permit gravity flow of water from the hotwell to the top of the cooling tower, thus eliminating the need for a pump. 

Although these units find initial application in areas of limited water, they have not been limited to this situation. In many instances they are more economical than cooling tower systems and have been successfully applied in combination with cooling towers (see Figure 10-184). Economic comparisons should include such items as tower costs, basin, make-up facilities, water treatment, pumps for circulation, power supply, blow down, piping, etc. For small installations of air-cooled units, they should be compared... 

Ground space often < cooling towers can also serve dual purpose by mounting air-cooled units above other equipment or on pipe ways or roofe of buildings. Vibration is no problem.

Bacteria are also responsible for destruction of wood, for example in cooling towers,20 by breaking down the cellulose fibers. Certain bacteria derive their metabolic energy from the iron(II)-iron(III) redox cycle. These iron bacteria can proliferate to the extent that they block pipes. In any case, they will discolor water. In addition, objectionable growths of algae can occur in water tanks or circuits, given even minimal supplies of nutrients. Consequently, biocidal agents are widely used in the treatment of industrial, as well as municipal, water supplies. 

Chandelon s method [60] is more widely used. Here 1 part by weight of mercury is dissolved in 10 parts of nitric acid (65% HN03, s.g. 1.40) by moderate heating the solution, heated to 55%, is poured into a flask or retort with a capacity at least 6 times that of the liquid, containing, apart from the above mentioned solution, 8.3 parts of 87% alcohol. The reactor is connected by a vent pipe with stoneware jars and a cooling tower in which the vapours evolved during the reaction are condensed. 

A method due to Strzoda 1 consists in passing the acid, after concentration in open lead pans, downwards through a series of vertical pipes heated externally by producer gas. The vapours evolved are passed through a cooling tower packed with suitable material, and the dilute acid recovered is passed back to the concentrating pipes. 

Outside battery limit (OSBL) defines the work and responsibilities outside the battery limit. The OSBL includes auxiliaries required for the chemical process unit, including tank storage for feedstock and refined products, waste treatment, cooling towers, flares, and utilities that are not included in the battery limit but are required for the unit. Also included are the pipeways, racks, and sleepers, which are used to convey all of the utility s interconnecting process piping to and from the processing facility...
