Tianjin University ( Beiyang University ) is the first educational institution of higher learning in China . As a key engineering integrated with Science university, Tianjin University plays a leading role in the basic principle research and industrial application of mass transfer fields , especially in the distillation ,absorption and so on processes. After decades of endeavor in these fields, Tianjin University has gained several key patents included by the national plan of ‘High efficient packed Column Technologies with the new Column Internals' in distillation field .

   Tianjin Tianda Beiyang Chemical Equipment Co.,Ltd.(PACTU) is owned by Tianjin University and is directly under the administration of it . Therefore PACTU is authorized by Tianjin University to use the patents freely and develop the technology of ‘High efficient packed Column Technologies with the new Column Internals' and popularize its industrial application. Nowadays, PACTU has been the leading supplier of distillation technology and equipments in China. We also seek the cooperation with the multination corporation to develop oversee performances.

    By the end of 2004, the overall assets of PACTU has been 52,100,000Yuan. In 2004, the overall production value of PACTU was 89,940,000 Yuan and the vendition income was 70,240,000Yuan .The pilot plant and manufacture plant of PACTU are located in the Tianjin University Industrial Area of Jinhai Developing District, the workshop area of which has exceeded 11,450 square meters .PACTU has a special engineering development team,which include over 30 chemical engineering experts with Master or high degree. These experts are in charge of the research and development of new products and technology. PACTU has about 200 workers, who have been trained by PACTU to be the master-hand of their positions.

   Supported by Tianjin University and motivated by the client's needs , PACTU cooperates with Chemical Engineering Research Institute and National Key Laboratory of Chemical Engineering to develop new distillation process and equipments and the convert the advanced technology into industrial application . Today, PACTU has integrated the technology development , manufacture and service into a whole .

   The technology of ‘High efficient packed Column Technologies with the new Column Internals'(HCTCI) is the principal axis of the development of new distillation process and equipment of PACTU, which includes series of patents owned by Tianjin University and PACTU and Know-how. PACTU has established several pilot columns that can be used in the experiments of normal pressure, vacuum , high pressure and batch distillation and absorption , which have played a key role in the development of new processes and equipments. By now, PACTU has gained 11 patents , including structured packing, distributor, tray and rectification process, part of which have been applied in the industrial installation widely and have achieved good performances.

   PACTU has gained ISO-9001:2000 certification of international standard quaity guarantee system and has been issued the manufacturing license of pressure vessels of type I, II by the Quality Inspection Bureau of China. In 2004, PACTU is valued the Tianjin High-Tech Corporation by the government of Tianjin city.

   PACTU owned 192 sets of manufacture devices ,including 36 sets of special devices, 38 sets of assistant devices , 50 sets of key devices ,51 sets of common devices and other inspection devices to ensure the quality of the products. PACTU has established a large hydraulic experiment device, which can check the performance of big internals( φ1500mm). All the key devices and most of the assistant devices are designed and produced by ourselves.

   Nowadays PACTU produces the following products:
1) 100 kind of structured packing , including Mellapak Packing, Meal Wire Gauze Structured Packing , Plastic Mellapak Packing and so on .
2)  Many kind of random packing .
3)  Many kind of internals, including channel distributor , through-pan gas-liquid distributor , supporter , limits and so on.
4)  All kinds of trays , including sieve tray, float valve tray and so on.
5)  All kinds of vessels, including tower ,tank, heat exchanger, reactor and so on.
   PACTU can produce 2200Nm3 of packing and 200 tons of internals per month.

   PACTU welcome your cooperation and hope to prosper with you sincerely!
