Viscosity Intex Impeover Plant

At Liuminex, we specialize in the design, engineering, and turnkey execution of Viscosity Index Improver (VII) Plants—an essential installation in the production of high-performance lubricants and oils. Our systems are built with precision and innovation to support the growing global demand for advanced lubricant formulations that perform consistently across a broad temperature range.
Viscosity Index Improvers are critical polymer additives used in lubricants to enhance their viscosity-temperature behavior. Our VII plants are engineered to deliver the highest quality products while optimizing operational efficiency, environmental safety, and long-term reliability.

What Is a Viscosity Index Improver?

A Viscosity Index Improver (VII) is a polymer-based additive used in the formulation of multigrade engine oils and industrial lubricants. It helps maintain the lubricant’s viscosity over varying temperatures, ensuring stable and effective lubrication during cold starts and at high operating temperatures.

VII compounds, such as olefin copolymers (OCP), polymethacrylates (PMA), and hydrogenated styrene-diene copolymers (HSD), are typically synthesized and blended in specialized process units. These compounds enhance the performance of engine oils by preventing excessive thinning at high temperatures and thickening at low temperatures.

Our Expertise in VII Plant Engineering

              We offer complete end-to-end solutions for the development of Viscosity Index Improver manufacturing plants, including:

  • Process Design & Simulation
  • Engineering, Procurement, and Construction (EPC)
  • Modular Skid-Mounted Units
  • Automation & Control Systems Integration
  • Commissioning, Training, and After-Sales Support

            Whether you’re upgrading an existing unit or building a new VII plant from scratch, our engineering team collaborates closely with your technical teams to deliver a customized solution optimized for productivity, safety, and compliance.

Applications of VII Additives

          Viscosity Index Improvers are widely used in the formulation of:

  • Multigrade Engine Oils (e.g., 10W-30, 5W-40)
  • Automatic Transmission Fluids (ATF)
  • Gear Oils
  • Hydraulic Fluids
  • Industrial Lubricants
  • Marine and Aviation Lubricants

          Our plants are tailored to meet the additive specifications required by leading lubricant brands and adhere to industry performance standards such as SAE, API, and ACEA.

Turnkey Project Delivery

               From concept to commissioning, we offer comprehensive project management and technical services including:

  • Feasibility Study & Techno-Commercial Proposal
  • Process Flow Diagram (PFD) and P&ID Development
  • Equipment Fabrication & Inspection
