Vaporizers; Vaporizer Applications [*]
Applications are easier to discuss with specific reference to certain models. (See Figs. V-1 through V-6.)
Figure V-1: Very large low-temperature vaporizer/superheater, steam heated. Unit size 132 in (3353 mm) in diameter by 42 ft (13 cm) long. Duty to boil and superheat very low-temperature organic liquid. (Source: Armstrong Engineering Associates.)
Figure V-2: One of six all-stainless-steel vertical vaporizers for vertical location above tower in Mideastern refinery. Unit size 59 in (1500 mm) in diameter by 20 ft (6100 mm) high. (Source: Armstrong Engineering Associates.)
Figure V-3: Indirect fluid electric heater insulated and mounted on skid with all controls in place. One of several at the same site in South America, vaporizing organic fluids. (Source: Armstrong Engineering Associates.)
Figure V-4: Large-sized ethylene vaporizer (steam in shell) with entering temperature of ethylene ?67 F ( ?55 C) installed in India. Steam-heated steel shell with stainless steel heat-transfer surface. (Source: Armstrong Engineering Associates.)
Figure V-5: Seven large hydrocarbon fluid vaporizers for chemical plant in Middle East. Unit size 36 in (914 mm) in diameter, overall height 135 in (3430 mm). (Source: Armstrong Engineering Associates.)
Figure V-6: In-tube cryogenic vaporizer/superheater with steam in shell and mixed hydrocarbons on tubeside. Steel shell with balance stainless steel for U.S. installation. (Source: Armstrong Engineering Associates.)
Types of Vaporizers
-
Vertical vaporizer ("vertical bayonet"): It is widely used for chlorine, ammonia, propane, methanol, sulfur dioxide, etc. Sizes range from 50,000 to 15,000,000 Btu/h...
