Core Technology

Butadiene Production Technology (RHBD)

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.

Low Carbon Olefin Production Technology (RHMTP)

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.

Low Carbon Olefin Production Technology (RHMTP)

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.

Crystallization technology of p-xylene

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.

Aromatics Production Technology (RHAROM)

Ruihua aromatics production technology can be used to produce benzene, toluene, xylene products. 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.

Capacity expansion technology for dry gas production of ethylbenzene

Up to now, there are some plants in China that have applied dry gas to ethylbenzene/styrene technology, mainly 6 to 80000 tons of styrene per year, distributed in PetroChina, Sinopec, China Chemical and various private enterprises. The dry gas method was used as raw material to produce ethylbenzene, which solved the problem of dry gas resource utilization at that time. However, in the actual production over the years, the vast majority of dry gas to ethylbenzene/styrene plant load can not reach the design value, not to mention the increase in styrene prices to increase capacity to increase efficiency.

Ethylbenzene/styrene production technology

Changzhou Ruihua Chemical Co., Ltd. has more than ten years of experience in ethylbenzene/styrene industrial engineering design, and successfully developed a complete set of ethylbenzene/styrene process technology at the beginning of the company's establishment. After nearly 10 years of technical improvement, the process package has reached the leading level in the latest operation of the device.

Butadiene energy-saving production technology

The position of butadiene in petrochemical olefin raw materials is second only to ethylene and propylene, and butadiene is the main raw material for the production of synthetic rubber (styrene butadiene rubber, butadiene rubber, nitrile rubber, chloroprene rubber). With the development of styrene plastics, the use of styrene and butadiene copolymer, the production of a wide range of resins (such as ABS resin, SBS resin, BS resin, MBS resin), so that butadiene in the resin production gradually occupy an important position. In addition, butadiene is still used in the production of 1,4-butanediol (engineering plastics), dicarbonitrile (nylon 66 monomer), sulfolane, tetrahydrofuran, etc., and is also an important basic chemical raw material.
