Butadiene Production Technology (RHBD)
Ruihua's technology for butadiene production by oxygen-enriched dehydrogenation of butenes uses different feeding methods and different feed compositions to solve the blockage of the second-stage reactor of the traditional oxidative dehydrogenation process and extend the catalyst operation cycle. Due to the change of the feed composition, the energy consumption of the entire device is greatly reduced.
Ruihua has conducted detailed research on the existing butene oxidative dehydrogenation unit, and can reasonably modify the existing unit. After a large number of experimental verifications, Ruihua's oxygen-enriched dehydrogenation process for butadiene production has a conversion rate of 2 to 3 percentage points higher than the butadiene yield of the traditional process. According to scientific verification and calculations, safety can also be guaranteed.
Ruihua can also treat alkynes produced in the process of oxidative dehydrogenation. Selective hydrogenation to remove alkynes into butadiene, butene, etc. can reduce material consumption and produce certain economic efficiency.
Ruihua has done a lot of work in the heat exchange network, and has developed a method for recovering low-level energy heat.
Treatment method of isobutylene in raw materials (self-polymerization)
The concentration of oxygen changes (the concentration of nitrogen decreases, other diluents can be added appropriately according to requirements)
Different feeding methods
Reasonable means of getting heat between segments
The utilization of integrated heat exchange networks such as heat pumps ensures the recovery of low-grade heat energy
Selective Hydrogenation Technology of Alkynes
Solve the problem of the blockage of the evaporator and increase the operating period
Reduced the production of polymer in the reactor
Energy consumption is reduced (there is a lot of nitrogen in the original process)
The use of heat pump technology reduces the loss of low-grade heat energy
The oxygen-enriched technology adds other diluents to avoid the risks caused by the presence of oxygen
