Amid the backdrop of rapid global expansion in the energy storage industry and the ongoing restructuring of lithium resource supply and demand, lithium extraction from salt lakes has become a critical production pillar of the new energy value chain. As the core equipment for brine lithium extraction and lithium-bearing mother liquor recovery, the MVR (Mechanical Vapor Recompression) evaporation system has become a standard and indispensable unit in both newly built and existing lithium extraction projects. Its performance directly determines a project's energy consumption costs, resource recovery efficiency, and operational stability at scale. However, the industry has long been affected by a common misconception: equipment updating is always prioritized over establishing a process system tailored to projects’ specific operating conditions, preventing high-quality equipment from delivering its full potential and value.
Nowadays, many salt-lake lithium extraction projects are facing similar challenges. Although their hardware infrastructure is fully in place, key MVR systems frequently suffer from scaling and tube blockages, short continuous operating cycles, high power consumption, and significant lithium losses in mother liquor. This issue is particularly pronounced because the feed brine used in many current projects is characterized by high magnesium-to-lithium ratios and elevated impurity levels. As a result, generic operating parameters and standardized process flows are unable to adapt to the unique conditions of different mining regions. Consequently, many projects experience production capacities that fall short of design targets, rapidly surging operation and maintenance costs, and extended payback periods, which has left numerous promising lithium resource projects in the awkward position of having advanced equipment installed and operating, yet failing to achieve the expected economic returns.
In reality, a mature MVR system is only the foundation for large-scale lithium production. The true determinant of a project's profitability lies in customized, precision-engineered process technologies that complement and optimize the equipment. As a global leader in Direct Lithium Extraction (DLE) technology development and implementation services, BICHEM has cultivated deep expertise in salt-lake lithium extraction over many years. Leveraging extensive technical know-how, advanced R&D capabilities, and a strong track record of successful project execution, BICHEM provides comprehensive solutions for MVR process optimization, operating-condition adaptation, and technical upgrading. Through technology-driven innovation, we help clients unlock the maximum production value of their equipment assets.
Unlike traditional optimization that merely focuses on upgrading hardware, BICHEM’s core strength lies in its deep understanding of the fundamentals of lithium extraction processes. With extensive knowledge of the operational characteristics of salt lakes across different regions and brines with varying chemical compositions, BICHEM has established a complete integration framework linking brine characteristics, MVR operating logic, and the end-to-end lithium extraction process. In addition, supported by a vast database of experimental results and a data-driven operations management system, BICHEM moves beyond the industry’s one-size-fits-all process templates, and develops tailored MVR process solutions based on each project’s unique feedstock characteristics, production environment, and capacity objectives, addressing critical industry challenges at their source and delivering sustainable operational improvements.
For new lithium extraction projects, BICHEM provides end-to-end customized MVR process solutions. For complex brines characterized by high salinity and high magnesium and calcium concentrations, BICHEM optimizes pretreatment processes and precisely align them with the full MVR workflow, including pre-concentration, brine separation, and mother liquor recovery. By fine-tuning critical operating parameters such as evaporation temperature, vacuum pressure, and feed/discharge ratios, impurity accumulation and heat-transfer surface scaling are effectively mitigated, which significantly improves lithium retention, minimizes lithium losses in the mother liquor, and enhances overall lithium recovery rates from the process perspective. Meanwhile, BICHEM eliminates process integration barriers between upstream pretreatment, midstream MVR concentration, and downstream lithium precipitation and crystallization. By ensuring seamless coordination across all stages of production, common issues such as capacity mismatches and inconsistent product quality are then successfully addressed, enabling stable, standardized, and large-scale commercial production.
For the vast number of underperforming existing production lines across the industry, BICHEM delivers targeted performance improvement solutions through comprehensive process diagnostics, parameter reconfiguration, workflow optimization, and advanced anti-scaling technology upgrades. These measures rapidly address challenges such as excessive energy consumption, frequent unplanned shutdowns, and insufficient production capacity. With relatively low capital investment, operators can achieve substantial cost reductions and efficiency gains, significantly shorten project payback periods, and unlock the full value of existing production assets.
Leveraging its global presence and access to world-class industry resources, BICHEM collaborates with leading partners across the lithium extraction value chain to integrate cutting-edge technologies with proven project execution expertise, establishing a standardized, professional, and sustainable lithium extraction process system. As a global leader in DLE technology innovation and commercial-scale deployment, BICHEM always place sustainability at the center of its strategies, balancing production efficiency with environmental compliance. Through closed-loop process design and precise process optimization, BICHEM promote water recycling and resource conservation, helping salt-lake lithium projects achieve eco-friendly operations while meeting stringent regulatory requirements and industry standards worldwide.
Ultimately, the core competitiveness of the new energy industry lies in the ability to refine and optimize technology. Improving efficiency and reducing costs in MVR-based lithium extraction is never simply a matter of selecting the best equipment; it is a comprehensive challenge that requires process adaptation, parameter optimization, and seamless integration across the entire production chain. Drawing on years of international project experience, a robust data-driven technology platform, and a highly customized service model, BICHEM breaks through the limitations of equipment homogenization and empowers every MVR system with precisely engineered process solutions, enabling the delivery of three critical operational outcomes: higher lithium recovery rates, lower energy consumption, and more stable large-scale production performance. Looking ahead, BICHEM will continue to advance innovation in salt-lake lithium extraction technologies. Guided by a global perspective, professional expertise, and full-lifecycle service capabilities, we remain committed to empowering lithium extraction projects worldwide, supporting the high-quality and sustainable growth of the new energy industry, and creating long-term commercial value for our clients.
