    PBS, PBAT CP Production Plant

    Technical Background of PBS:

    CP PBS & PBAT Production Machinery | As the concerns over white pollution and the non-renewable energy crisis grow more severe, the development and utilization of biodegradable plastics have emerged as an effective solution. Among these biodegradable plastics, PBS stands out as a leader due to its excellent biodegradability and heat resistance.

    PBS Industrialization Project:

    In 2002, the Chinese Academy of Sciences (CAS) listed the industrialization project of PBS as an innovation project. Subsequently, in 2005, they recognized PBS as one of the key issues in environmentally friendly materials. The government has placed a strong focus on promoting the industrialization of PBS.

    Quality Index of PBS:

    We prepare our PBS (Polybutylene Succinate) from 1,4-succinic acid (SA-1,4) and 1,4-butanediol (BDO) through continuous esterification and polycondensation processes.

     

     

    Quality Index:

    • Density: 1200～1280kg/m3
    • Average Molecular Weight: ≥150,000
    • Melt Index: ≤10g/10min
    • Intrinsic Viscosity: ≥1.8dL/g
    • Melting Point: 110～130℃

    Characteristics and Applications of PBS Products:

    PBS can be derived from either petroleum resources or the fermentation of biological resources. It possesses remarkable heat resistance, allowing products made from PBS to withstand temperatures exceeding 100℃.

    Moreover, PBS is easily decomposed and metabolized by various microorganisms and enzymes in nature, ultimately breaking down into carbon dioxide and water.

    Applications of PBS:

    • Widely used in everyday life
    • Agricultural materials, including agricultural film, pesticides, and slow-release fertilizers
    • Biomedical polymer materials

    PBS & PBAT Production Plant Process Brief

    Our advanced PBS Production Machinery Plant follows a streamlined and efficient process, ensuring top-quality biodegradable material production. The production line features a setup of five reactors in series, all designed to achieve outstanding results:

    1. Vertical Esterification Reactors with Agitator: The first step involves two vertical esterification reactors, featuring agitators for optimal mixing. This crucial stage sets the foundation for the subsequent processes.
    2. Falling Film Tower Pre-polycondensation Reactor: Next, the pre-polycondensation reactor, utilizing a falling film tower design, further refines the materials, preparing them for the final stages of production.
    3. Cage-frame Final Polycondensation Reactor: Within the cage-frame reactor, the polycondensation process reaches its pinnacle, resulting in the formation of high-quality PBS biodegradable material.
    4. Horizontal Single/Double-axis Tackifying Polycondensation Reactor: The last reactor in our production line employs a horizontal single/double-axis tackifying polycondensation design, adding the finishing touches to the PBS biodegradable material.

    Single/double-axis tackifying polycondensation reactor

    In a single/double-axis reactor, the melt forms a film between rotating gears. Simultaneously, small molecule BDO is continuously removed under high vacuum conditions, leading to a further condensation reaction. This process results in the product achieving higher viscosity.

    Recovery of THF from esterification wastewater

    During the esterification stage, the production of PBS generates a byproduct called tetrahydrofuran (THF) from BDO. Subsequently, this THF is carried along with the esterification vapor into the separation tower, where it is then extracted from the esterification water. To maximize resource utilization, we have implemented a specialized tetrahydrofuran recovery unit to efficiently reclaim THF from the esterification water. As a result, the recovered THF holds valuable applications as a solvent or can serve as a raw material for various organic synthesis processes. This eco-conscious approach not only ensures optimal production efficiency but also promotes sustainable practices within our PBS Petrochemical Production Plant.

     

     

    With our well-engineered and meticulously designed production line, we ensure the efficient and reliable manufacturing of PBS, a leading biodegradable material that aligns perfectly with environmentally conscious goals.
