Ruihua butene oxygen-rich dehydrogenation of butadiene technology using different feed methods, different feed composition, can solve the traditional oxidative dehydrogenation process two-stage reactor blockage, extend the catalyst operation cycle. Due to the change of feed composition, the energy consumption of the whole plant is greatly reduced.
The production technology of Ruihua C4 cracking plant transformed into methanol to propylene can be used to produce propylene, ethylene, liquefied petroleum gas and aromatic gasoline. This technology is highly adaptable to the market, and the product plan can be adjusted according to demand, making it very competitive in small and medium-sized industrial applications.
Maleic anhydride is one of the world's three major anhydride raw materials (acetic anhydride, maleic anhydride, phthalic anhydride), and its downstream products have a wide range of development and application prospects, can be used in synthetic resins, coatings, pesticides, lubricating oil additives, pharmaceuticals, paper treatment agents, food additives, stabilizers and so on.
The process of crystallization separation of p-xylene is still in use now is an older process, before the emergence of adsorption separation technology, crystallization separation of p-xylene is the only technology of p-xylene refining. Due to the development of adsorption technology, the existing crystallization technology for the separation of mixed xylene of equilibrium components has no advantage, but for the separation of mixed xylene materials with high concentration of p-xylene is still attractive.
