Steam trap assembly

Steam Traps - Steam trap assemblies are usually shown in the P ID s but no cost has been provided elsewhere. An allowance is included here. 

Steaming-out the steam distillation apparatus. After the cleaned steam -distillation apparatus (Fig. 88) has been assembled, it is essential to pass steam through it for some time to remove readily soluble alkali. All the taps on the apparatus are opened and the water in the steam generator boiled vigorously. The steam will gradually pass into the apparatus. After a few minutes, the tap of the tap-funnel C may be closed and soon afterwards the tap Ti of the steam-trap finally the tap Tj of the funnel G may be closed, Steaming-out should then be continued for not less than one hour, the receiver J not being in place. 

Steam system. Clean steam is used for all equipment that comes into contact with containers, solution, or closures prior to product assembly. Pure steam is produced by a generator fed by deionized water. Steam traps are installed to collect condensate when necessary. The quality of pure steam condensate is the same as water for injection. The quality of pure steam is monitored through a quality analyzer system that measures the conductivity of condensed pure steam. 

One 2-inch diameter insulated steam manifold complete with filter and trap assembly. Six 1/2-inch valved connections and two capped spaces. 

In the steam-distillation assembly (Note 1) one of the small necks of the flask is fitted with a steam-inlet tube, connected through a water trap to a steam line the other small neck is closed by a cork. The central neck is fitted to a Kjeldahl trap leading to a 50-cm. Allihn condenser set downward and connected in series to a 50-cm. Liebig condenser. The second condenser leads to a SOO-ml. three-necked flask used as the receiver. The receiving flask is immersed in an ice bath and fitted with an Allihn reflux condenser. 

In the assembly shown in Fig. 3 steam is passed into a 250-mL, round-bottomed flask through a section of 6-mm glass tubing fitted into a stillhead with a piece of 5-mm rubber tubing connected to a trap, which in turn is connected to the steam line. The trap serves two purposes it allows water, which is in the steam line, to be removed before it reaches the round-bottomed flask, and adjustment of the clamp on the hose at the bottom of the trap allows precise control of the steam flow. The stopper in the trap should be wired on, as shown, as a precaution. A bent adapter attached to a long condenser delivers the condensate into a 250-mL Erlenmeyer flask. Measure 50 mL of a 0.2% solution of anthracene in toluene into the 250-mL round-bottomed flask and add 100 mL of water. For an initial distillation to determine the boiling point and composition of the toluene-water azeotrope, fit the stillhead with a thermometer instead of the steam-inlet tube (see Fig. 5 in Chapter 5). Heat the mixture with a hot plate and sand bath or...
