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.
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.
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.
Sovonex™ 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.
Sovonex™ 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.
Although Sovonex™ 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, Sovonex™ distillation towers are suited even for the harshest applications.
