AKU Kettle Reboiler

Technical Specifications of AKU Kettle Reboiler
(Based on TEMA Naming Convention)

It should be noted that "AKU" is not an official TEMA designation. In industry practice, AKU typically refers to an Accessible Kettle-type Reboiler, which combines a removable front cover with kettle-type boiling design. Below are the technical parameters:

1. Naming Convention Analysis (Industry Practice, Non-TEMA Official)

o A: Front Head Type (A = removable flat cover for maintenance and cleaning).
o K: Shell Type (K = Kettle-type shell).
o U: Rear Head Type (U may denote "Utility" or "User-friendly", emphasizing maintainability).
o AKU is not a standard TEMA code but a customized name used by end-user for accessible kettle reboilers.
o Its design combines features of TEMA K-type shell (kettle) and A-type front head (removable cover).

2. Key Technical Parameters (Based on Accessible Kettle Design)

Parameter	Typical Value/Range	Remarks
Design Standard	ASME VIII Div.1 / TEMA K	Standard for kettle reboilers
Heat Transfer Area	50~2000 m²	Immersed tube bundle design
Design Pressure (Shell Side)	0.5~6.0 Mpa (5~60 bar)	High-pressure models up to 10 Mpa
Design Temperature	-50°C to +400°C	High-temperature models up to 450°C
Shell Material	Carbon Steel (Q345R) / SS304 / SS316L / Clad Plate	Corrosion-resistant options
Tube Bundle Material	SS304 / SS316L / 2205 Duplex / Titanium	Anti-cavitation design
Tube Diameter/Length	Φ19~Φ50 mm / 3~12 m	U-tube/straight tube options
Heat Source	Steam (0.3~1.5 Mpa) / Thermal Oil / Molten Salt	Multi-energy compatibility
Vaporization Rate	30%~100%	Adjustable per column demand
Level Control	Auto-level gauge + control valve	Dry-run protection
Removable Front Cover	A-type flat cover + bolted connection	For tube inspection and cleaning
Connection Standard	ANSI / DIN / GB Flanges	DN150~DN800

3. Structural Features

o Removable Front Cover (A-Type): Bolted flat cover allows tube bundle inspection and shell bottom cleaning.
o Kettle-Type Shell (K-Type): Large-volume shell provides stable boiling space; top-mounted demister reduces liquid entrainment.
o Immersed Tube Bundle: Tubes fully submerged for high vaporization efficiency.
o Anti-Fouling Design: Removable structure supports mechanical cleaning, suitable for fouling-prone media.

4. Typical Applications

o Petroleum Distillation: Atmospheric/vacuum columns, catalytic cracking units
o Chemical Separation: High-boiling solvents (e.g., DMF, DMSO) evaporation
o Pharmaceutical Concentration: Solvent recovery, extract evaporation

5. Data Required for Selection

o 1.Process Requirements: Vaporization rate (kg/h), inlet/outlet temperatures, operating pressure.
o 2.Fluid Properties: Composition, viscosity, boiling point, corrosiveness (e.g., Cl⁻, H₂S).
o 3.Heat Source: Steam pressure or thermal oil temperature.
o 4.Cleaning Requirements: Determines need for removable structure.

6. Comparison with Standard TEMA K-Type

Feature	AKU Accessible Kettle Reboiler	Standard TEMA K Reboiler
Front Structure	A-type removable flat cover	Fixed head or simple manway
Maintainability	Front cover removable for inspection and cleaning	Limited access via manway
Cost	Higher (complex removable structure)	Lower
Fluid Compatibility	Fouling-prone or inspection-needed media	Clean or chemically cleanable media

Note: AKU reboilers require custom design. Directly provide operational requirements to manufacturers-WUXI YITENG.
