How MVR Systems Support China’s “Dual Carbon” Goals: A New Pathway for Industrial Emission Reduction？

06 Aug, 2025 10:16am

As China advances its national strategies of carbon peaking and carbon neutrality, industrial enterprises are accelerating their transition toward green and low-carbon operations. In energy-intensive sectors, thermal energy recovery and resource reuse have become essential to reducing emissions. Among the most efficient technologies available, Mechanical Vapor Recompression (MVR) systems stand out for their energy-saving, stable, and low-carbon performance. Today, MVR evaporators have become a core component in helping enterprises achieve their “dual carbon” targets.

WTEYA, as a leading provider of customized evaporation system solutions, is committed to delivering high-performance and low-energy MVR systems. With successful deployments across chemical, pharmaceutical, food, and environmental industries, WTEYA provides strong technical support for corporate energy saving and emissions reduction.

How MVR Systems Work and Achieve Energy Efficiency

At the core of MVR systems is the concept of reusing secondary steam generated during evaporation. A mechanical compressor increases the pressure and temperature of the steam, allowing it to serve as a heat source for subsequent evaporation cycles—dramatically reducing external steam consumption.

Operation Workflow:

The feed liquid is preheated and enters the evaporator, generating both primary and secondary steam.
Secondary steam is compressed mechanically to raise its enthalpy (temperature and pressure).
The compressed steam is reused as a heat source for further evaporation.
Steam condenses into water, while the concentrate is discharged from the system.

By replacing external thermal energy with recycled steam, MVR systems establish a closed-loop energy cycle, significantly lowering total operating energy consumption.

Compared to traditional multi-effect evaporators, MVR systems consume only 1/3 to 1/5 of the energy, with specific energy use as low as 15–40 kWh per ton of evaporation, enabling long-term, stable, and efficient operations.

MVR Systems and the Dual-Carbon Strategy

1. Significant Reduction in Carbon Emissions

Traditional thermal systems rely on fossil fuels such as coal or natural gas, resulting in high carbon emissions. MVR systems reduce boiler steam demand by recycling their own vapor, drastically cutting CO₂ at the source. When powered by clean energy (e.g., solar or wind), MVR systems can even achieve near-zero carbon operation.

2. Reduced Energy Intensity

Conventional multi-effect evaporation typically consumes 0.8–1 ton of steam per ton of water processed. MVR systems reduce this to the energy equivalent of only 0.05–0.1 tons of standard coal, delivering energy savings of up to 70%–90%. For large-scale applications, this translates into substantial long-term energy and cost savings.

3. Green Compliance and ESG Alignment

MVR systems contribute positively to national green factory assessments, environmental audits, and ESG metrics. Enterprises using MVR technologies benefit from easier compliance, access to green financing, government incentives, and carbon asset recognition.
