Detailed description
Overview
Changzhou Ruikai Chemical Equipment Co., Ltd. is located in Rulin Town, Jintan District, Changzhou. It has A2 pressure vessel manufacturing qualification and is wholly owned by its parent company, Changzhou Ruihua Chemical Engineering Technology Co., Ltd. Specializing in ethylene storage and transportation, aromatic alkylation (ethylbenzene/p-xylene), aromatic dehydrogenation (styrene/methylstyrene/divinylbenzene), expandable polystyrene (EPS), isobutane normal structure, butane maleic anhydride, indirect oxidation propylene oxide (ethylbenzene, cumene, isobutane), hydrogenation (crude benzene, benzene, maleic anhydride) and a series of chemical core equipment research and development, design and manufacturing business.
Our company has obtained a number of authorized patents, and used in the production of manufacturing technology:
ZL2018222518774， ZL2019205302171， ZL2019208220309，ZL2019208495000.0，ZL201920849559X， ZL2019209609761.1，ZL2019209842770， ZL201921001494X， ZL2019209921147， ZL2019209969432，ZL2015103015639，ZL201905536766 , ZL2020225021084 , ZL2020227234920
Since its establishment in 2014, our company has manufactured hundreds of equipment for the manufacture of products in the chemical industry in the past 6 years.
Overview
In China, the performance of ethylbenzene/styrene industry covers East China and North China, with more than 10 sets of devices in operation and projects under construction. The maximum production capacity reaches 350000 tons/year (in terms of styrene), and the design capacity can reach 600000 tons/year.
Moreover, we have maintained long-term and close technical cooperation with many engineering design institutes and catalyst suppliers at home and abroad. To ensure that the process technology is mature and reliable and in a constantly updated state, to maximize the benefits to the user.
Key patent technology: ethylbenzene dehydrogenation reactor adopts the way of axial radial flow of materials in the reactor. The uniform distribution of the fluid adopts a double-curved cone, which eliminates the pressure drop of the perforated plate through the hole, rationally uses the radial flow technology, optimizes the design of the collection and shunt flow channel, and makes the pressure drop of the reactor meet the requirements of the negative pressure reaction.
Ethylbenzene dehydrogenation high-temperature heat exchanger was recognized by Changzhou's first (set) of major equipment and key components in 2017.
