At the beginning of the year, Shandong Lanwan New Materials Co., Ltd. sent a heartfelt commendation letter to Shanghai دودجن Chemical Technology Co., Ltd. The letter stated that the acrylic acid melt crystallization project undertaken by دودجن has been successfully completed and put into operation smoothly, with the core equipment running stably and all performance indicators meeting or exceeding the design requirements. This is not only a high recognition from the client but also strong evidence of دودجن‘s outstanding engineering capabilities.
Following this good news, more positive developments ensued—Shandong Lanwan and DODGEN officially signed the Phase II order, continuing to select DODGEN’s leading melt crystallization process package and core key equipment.
Commendation Letter from Shandong Lanwan
One-Time Successful Startup—Flawless Delivery Wins Client Praise
In Shandong Lanwan’s acrylic acid purification project, DODGEN achieved a one-time successful startup of the plant. Behind this achievement is the DODGEN technical team’s ability to overcome challenges such as tight schedules, heavy design tasks, and stringent technical requirements. They remained on-site, scientifically formulating technical plans and efficiently guiding field operations.

International-Level Process—Providing Leading Solutions for the High-Purity Acrylic Acid Market
High-purity acrylic acid (glacial acrylic acid, GAA) is a core raw material for high-end applications such as superabsorbent polymers (SAP), premium pressure-sensitive adhesives, and high-performance coatings. With global consumption upgrades, downstream markets are imposing increasingly stringent requirements on raw material purity.
Acrylic Acid and Its Applications
DODGEN’s independently developed and continuously iterated dynamic melt crystallization technology route is a process solution tailored to these stringent demands. By precisely controlling the temperature gradients and time sequences for crystallization, sweating, and melting, it achieves efficient separation at the molecular level, with core process indicators reaching and surpassing international advanced levels:
· Main Content of Product: Acrylic acid main content stably ≥99.95 wt%;
· Key Impurity Control: Maleic anhydride reduced to below 10ppm, color ≤5 APHA;
· Overall Yield: >96%, significantly reducing raw material consumption and practicing green chemistry;
· Operational Flexibility: 70%–100% wide-range flexible operation, with 8000 hours of annual operation time.
This set of data not only meets but far exceeds industry general superior product standards, demonstrating DODGEN’s hardcore strength on par with international first-class levels.
Professional Strength—Deep Technical Accumulation Escorts Client Projects
DODGEN has been deeply cultivating the fields of chemical process intensification and high-end separation for many years, precisely grasping the goals of minimizing client project risks and maximizing benefits:
· Autonomous and Controllable Process Package: Providing a complete process package including PFD, P&ID, and material balance, covering the entire process from basic design to detailed design review;
· Independent Production of Key Equipment: Core equipment with independent production capabilities, ensuring controllable quality and performance standards for key components;
· On-Site Service for Startup Guarantee: From DCS configuration, operation training to startup guidance, the technical team remains on-site to ensure smooth plant commissioning;
· Localized Quick Response: A highly cost-effective localized technical service team that responds quickly to client needs, ensuring smooth project implementation.
It is this professional capability that deeply integrates process R&D with engineering practice, enabling DODGEN to deliver precise efforts in key areas such as technical solutions, core equipment support, and on-site startup assistance, making it the most reliable professional technical partner for clients.
Trust is the Best Reputation—Renewal and Trust in Phase II Project
Shandong Lanwan’s renewed choice is not accidental but inevitable. After the perfect delivery of the first project, the client made the decision in the shortest time to entrust large-scale core production tasks to DODGEN.
DODGEN will, as always, continue to provide clients with internationalized engineering solutions with a professional, rigorous, and efficient attitude.
