CHEMICAL INDUSTRY

FILTRATION AND SEPARATION SOLUTIONS

In the chemical industry, chemical production environments are complex, often involving extreme conditions such as high temperature, high pressure, strong corrosion, and flammability/explosiveness.

UNITE provides integrated filtration systems to ensure the stability of the process, improve product purity, recover expensive materials, and protect strategic components of core equipment.

Typical Applications

Leveraging its deep industry expertise, UNITE provides one-stop technical support for the entire chemical industry value chain, encompassing filtration, separation, and drying. Our system designs prioritize both flexibility and stability, perfectly adapting to complex and ever-changing production conditions. UNITE offers first-class filtration solutions for the chemical industry that are used all over the world. For optimum functionality, we not only consider the equipment itself, but also the environment in which it is operated.

Catalyst/ Precious Metal Recovery

Chemicals/ Formaldehyde/ Organic Solvents/ Ammonia/ Strong Acids and Bases

Highly Toxic, Flammable and Explosive Media

High-Viscosity Chemical and Resin Products

Coal-to-Oil, Coal-to-Olefins/ Aromatics, Coal-to-Gas, Coal-to-Ethylene Glycol Projects

Raw Material Pre-treatment and Catalyst Protection

Chemical reactions typically rely on catalysts, but impurities in the raw materials can "poison" and deactivate the catalyst.

Fluid Purification: Before entering the reactor, solid particles in crude oil, monomers, or solvents are removed using high-precision filters.
Particle Interception: This protects the expensive downstream catalyst

bed from being covered by impurities, extending its replacement cycle and directly reducing operating costs.

Solid-Liquid Separation in Core Processes (Filtration, Drying, and Recovery)

In fine chemical and polymer production, filters are directly involved in the product formation process.

Filter Cake Formation and Washing: Pressure filters or vacuum filters are used to separate precipitated crystals, pigments, or polymers from the mother liquor, followed by in-line washing to improve product purity.

Catalyst Recovery: After the reaction, a precision filtration system is used to recover precious metal catalysts suspended in the liquid phase.

Process Integration: Modern systems (such as UNITE's three-in-one equipment) often integrate filtration, washing, and drying in a closed container to prevent leakage of toxic or flammable solvents.

Circulation Systems and Environmental Protection

Cooling Water Filtration: Chemical circulating water systems use fully automatic backwashing filters to intercept algae and scale, preventing scaling in cooling towers and heat exchanger tubes that would reduce heat exchange efficiency.

Solvent Reuse: Deep filtration of waste solvents generated during the

process enables solvent recycling, meeting Green Chemistry standards. Wastewater Compliance: Terminal filtration before wastewater discharge ensures that the suspended solids (SS) content meets environmental regulations.
