Neopentyl glycol technology
Thread Content
Technology for 10,000-ton peroxide glycol plants 1. Unit consumption (average or lower) for 10,000-ton peroxide glycol: isobutyraldehyde 0.765 t/t, formaldehyde 1.78 t/t, liquid caustic 1.48 t/t； Power consumption: 280 kWh ； 9 tons of steam. 3 tons of wastewater. 2. Process technology features 1.1 Self-optimization of catalyst ratio and components to achieve good selectivity and high conversion rates. 1.2 The reactor features a unique fixed-bed design, which offers a large material loading capacity and low investment costs. It maintains an appropriate reaction temperature, results in few side reactions, and is suitable for scale-up. 1.3 The unique multi-stage vaporization and vacuum distillation technology along with separation process not only simplifies the process, reduces investment costs, but also features high efficiency and low energy consumption. 1.4 Use of dealcoholization and dealdylation techniques ； Neopentyl glycol has good quality and does not clog ； Sodium formate has a good color.

I would like to ask the original poster: what is the biggest challenge you have encountered when using neopentyl glycol in operation? Where is the production bottleneck?
Our company wants to install a new pentanediol processing unit; could you send us some information on this topic? Thank you! GQLLB2009@126.COM
