烧碱蒸发精制氯碱行业解决方案——按需匹配，兼顾纯净与经济
烧碱蒸发精制是氯碱行业对产品纯度和设备保护要求极高的环节。回流碱液严禁引入Fe²⁺等金属离子，否则将污染成品、腐蚀设备；而非回流碱液则更关注成本与维护便利性。如何在不同工况下实现最优阀门配置，是提升整体效益的关键。
山东龙飞机电设备有限公司推出烧碱蒸发精制场景化进口阀门解决方案：
-
回流碱液：强制使用Kammer 132000衬塑单座阀，全PFA内衬彻底隔离金属接触，确保NaOH高纯度；
-
非回流碱液：采用MOTOYAMA 3889单座阀（304阀体+316内件），性能稳定、性价比高，满足常规控制需求。
该方案已在多个高端氯碱项目中落地，实现“该省则省、该严则严”的精细化管理。
龙飞以工况为导向，为氯碱行业提供科学、合规、经济的阀门选型策略，助力企业降本增效与品质升级双丰收！
Caustic soda evaporation and purification: matching purity and cost requirements
Caustic soda evaporation and purification impose demanding requirements on product purity and equipment protection. Recirculating caustic liquor must not introduce metal ions such as Fe²⁺, which can contaminate the product and corrode equipment. Non-recirculating liquor places greater emphasis on cost and ease of maintenance. Selecting the right valves for each service is key to overall efficiency.
Shandong Longfei offers application-specific imported valve solutions:
- Recirculating caustic liquor: the specified solution requires Kammer 132000 lined single-seat valves. Full PFA linings isolate metal surfaces from the process medium to maintain NaOH purity.
- Non-recirculating caustic liquor: MOTOYAMA 3889 single-seat valves with 304 bodies and 316 trim offer stable, cost-effective performance for conventional control requirements.
This approach has been implemented in several high-end chlor-alkali projects, applying strict specifications where necessary and saving costs where appropriate. Longfei provides application-driven, compliant and economical valve selection strategies to improve efficiency and product quality.
