Recently, the QY-VD vacuum distillation solution purification equipment, independently developed by Chengdu NENGJING Technology Co., Ltd., was successfully installed, commissioned, and put into operation at a fertilizer plant in Northwest China. The project successfully resolved the plant's long-standing decarbonization solvent regeneration challenges, marking another landmark case for NENGJING's solution purification services under high-altitude and complex working conditions.

As a long-term partner of NENGJING for many years, the customer has faced multiple challenges over time due to prolonged production operations, including feed gas quality fluctuations and equipment aging. Consequently, basic online purification equipment could no longer meet their processing needs. In response to this specific scenario, and backed by long-term tracking and monitoring of solvent quality, NENGJING's technical team designed a customized solution centered on vacuum distillation technology.

The project coincided with the customer's annual major overhaul, presenting a tight schedule and heavy workload. NENGJING responded rapidly, completing equipment delivery and piping installation ahead of schedule to ensure a seamless integration with the client's overhaul timeline. Simultaneously, the company deployed a professional on-site team to conduct systematic training for the client's operators, covering core aspects such as equipment principles, operating procedures, and emergency troubleshooting.

To tackle the specific environmental challenges of high-altitude regions—such as low atmospheric pressure and shifting boiling points—NENGJING's technical team tailored and optimized the parameters of the customized purification process, ensuring stable operations in a plateau environment. Following the training, the technical personnel remained on-site to oversee continuous equipment operation through two full cycles, with all performance indicators meeting the design requirements.

The successful execution of this project underscores NENGJING's core business philosophy: "Technology First, Service Foremost". From initial solution design and equipment commissioning to personnel training and long-term operational support, NENGJING delivers a full-chain professional service, empowering long-term customers to achieve sustainable green production while reducing costs and improving efficiency.
