For industrial DMF (Dimethylformamide) wastewater treatment and solvent recovery, Tiei Extraction provides a fully integrated centrifugal extraction process solution covering capacities from 1 to 60 m³/h, helping chemical, pharmaceutical,…
In fine chemical production processes, the water washing stage is a critical step for removing impurities from the organic phase and ensuring product purity. However, many enterprises still rely on traditional reactors or mixer-settlers for batch water washing operations, which…
Furfural, chemically known as furfuraldehyde (furan-2-carbaldehyde), is an important chemical raw material with extensive industrial applications. It serves as a selective solvent for separating unsaturated aliphatic compounds from saturated aliphatic compounds and is also a key intermediate for the production…
In the pharmaceutical and chemical industries, dimethyl sulfoxide (DMSO) is widely used as an excellent polar solvent. However, its wastewater is characterized by high COD, high salinity, and poor biodegradability, making it a persistent challenge in environmental treatment. How can…
In fine chemicals, pharmaceuticals, and solvent recovery industries, the separation of n-hexane and n-butyl ether is a common yet technically challenging process. Although their boiling points differ (n-hexane ~69°C; n-butyl ether ~142°C), conventional distillation methods often involve high energy consumption,…
