Knowing What is Important

The crude oil distillation unit (CDU) takes up a major part of the investment costs of any refinery. It is also the most energy consuming part of oil processing. Thus, choosing the right distillation tower can save a significant amount of money in the short term as well as in the long term.

All Distillation Columns Covered

At our manufacturing plant in China we have been manufacturing distillation columns of many different types and sizes for use in refineries, chemical plants, and pharmaceutical factories. If you have any special requirements, we are sure our engineers can meet them.
 

Tray Type Towers

We design tray columns (staged-contact columns) equipped with sieve trays, valve trays, or bubble cap trays. The highest tray tower we manufactured so far was 71 meters in height. It was shipped in three parts, with the final assembly, heat treatment, flaw detection and pressure testing all being conducted onsite.
 

Packed Towers

ELEGANT packed columns (continuous-contact columns) can be tailored exactly to your specific design requirements. Starting with the dimensions and type of structured packing, we can adjust any parameter of the packed column as specified.
 

How We Build Reliable Distillation Columns

ELEGANT crude oil distillation columns are tailor-made to customer requirements to achieve maximum accuracy and efficiency.
Years of experience in the development of pressure vessels for the petrochemical industry allow us to design and manufacture most related equipment, such as shell & tube heat exchangers and air-cooled heat exchangers.
With this expertise we are able to provide an even higher operational efficiency at minimum power consumption.
 

Not Only for Oil Processing

Although ELEGANT distillation towers are frequently employed at refineries, we also supply distillation units to the chemical, pharmaceutical, and food industry.
Developing distillation columns for different kind of applications is where our experience and extensive design capabilities pay off.
Experienced in the processing of a wide selection of materials, including titanium alloys, ELEGANT distillation towers are suited even for the harshest applications.
Pressure Vessel Standards
We can build our pressure vessels according to the following standards:

All Applications Covered
ELEGANT heat exchangers are used in a wide variety of applications, but we especially excel at manufacturing cooling systems for the oil processing industry.
With many years of experience in the field and our ability to design and manufacture to TEMA R, ELEGANT shell and tube heat exchangers are frequently used in refineries.
In fact, we construct and provide complete cooling systems for refineries such as finned tube air coolers.

Simple and Rigid Design
ELEGANT shell and tube heat exchangers comprise of a pressure vessel (shell) containing a bundle of tubes. The ends of the tubes are secured on a mounting plate (tube sheet) that can be either fixed to the shell or movable.
Exhaust fluid passes through the tube bundle. Heat is transferred away from the fluid by circulating a cooling medium inside the shell over the tubes. Using finned instead of bare tubes increases heat transfer by providing a larger surface area.
More than one heat exchanger may be combined to form a large single cooling unit, especially when skid-mounted.

Key Design Advantages
ELEGANT shell & tube heat exchangers combine the following key advantages:
Suitable for use in systems with high pressures and operating temperatures
Space-saving due to compact design and the ability to vertically stack several heat exchanger units.
Cost-effective, especially for large flow volumes

Shell & Tube Heat Exchanger Tube Bundle Designs
The performance of a shell and tube heat exchanger is mainly determined by the design of its tube bundle. Each design comes with a different set of advantages and limitations.

Fixed Tube Sheet
Design feature: Both tube sheets welded to the shell.
Advantages
Simple and economical design
The inside of the tubes can be cleaned
Limitation: No room for expansion of the tubes at high temperatures

U-Tube Bundle
Design Feature: Tubes bend on the shell site and fixed on a movable tube sheet on the tube side.
Advantages
Full thermal expansion of tubes possible
Tube bundle can be removed for cleaning on the outside
Limitations
Only even tube passes possible
More expensive than using a fixed tube sheet

Removable Bundle
Design Feature: The tube sheet of the rear header is not welded to the shell.
Advantages
Full thermal expansion of tubes possible
Tube bundle can be removed for cleaning on both the outside
Limitation: More expensive than using a fixed tube sheet and U-tube.

Why We Build Great Shell & Tube Heat Exchangers
We manufacture shell and heat exchangers of all TEMA types, such as BEM, CFU, and AES.
To save valuable floor space, ELEGANT S&T heat exchangers have a compact design and aim for a skid-mounted layout where possible.
With many years of experience, we know what is important and where the pitfalls are. This enables us to tailor each s&t heat exchanger to your specific requirements and make sure it is delivered in full compliance with the specifications.
