Vertically mounted temperature

Termaks (36) produces the Series 6000 and 8000 Environmental Chambers, Figure 22, to meet the needs for control of temperature, humidity, and light. Their interiors are all stainless steel. Light is supplied by 16 (8 per side), vertically mounted lamps, isolated from the interior chamber by a three-layer glass panel. The lamps are regulated by an adjustable electronic control.

After condensation, the liquid impurities are not warmed very much before they are removed to prevent re-evaporation. To accomplish this, the heat exchanger is separated into three vertically mounted sections, as shown in Fig. 5, with impurity removal taps at the bottom of each section. ITie liquid impurities which are removed from the first tap, if at room temperature, are pentane, butane, and water. The second tap drains off principally propane and ethane while the last removes methane. The heat exchangers used are of the Giauque-Hampson type shown in Fig. 2. The impure gas flows on the outside of the tubes while the purified gas flows countercurrent through the inside of the tubes. 

Altliough some reactors (e.g., those u.sed in methanol and catalytic reforming units) are. spherical, most are vertically mounted ve.ssels with elliptical heads. There are fewer connections for the plant layout designer to be concerned with than there are with the dLstillation tower. Generally, connections are limited to inlet and outlet, maintenance access, unloading,. sample, and temperature. Internally, reaaors are furnished with bed supptms, screens, inlet baffles, outlet collectors, catalysts, and inert materials. Exhibit 9-3 depicts a typical reactor and its principal components. 

The ID model simulates tank drain through the vertically mounted LAD in 1-g. It calculates the total pressure drop across the screen as a function of the pressure and temperature inside the tank by computing each of the four terms at each liquid level. In an iterative fashion, the code continues to run as the tank is drained until APtotai > APbp to compare the model predicted breakdown height against the actual breakdown height. The model assumes that liquid flow enters the channel uniformly through the available wetted screen area. The model also assumes uniform flow down the channel.
