Butanediol (BDO) is a crucial organic and fine chemical raw material used in the production of engineering plastics and fibers. The Reppe method, also known as the alkyne-formaldehyde method, is the main production process for BDO, involving alkyne and hydrogenation reactions to produce BDO.
Filtration is a crucial process in the BDO production, used for separating catalysts and purifying materials. It comes in various forms with diverse requirements, but all play an important role. Examples include BYD filters and hydrogenation catalyst filtration.
BYD filter
- The catalyst is intercepted in the reactor to reduce the transmission process, reduce energy consumption and catalyst loss. Catalyst utilization rate is improved.
- Integrated design reduces the footprint.
