Product quality, operational effectiveness, and material recovery are crucial elements that have a direct bearing on profitability and customer satisfaction in the lubricant manufacturing sector. Inaccurate dosage, excessive product loss, contamination hazards, and higher operating expenses are frequently the results of manual mixing and material transfer systems. 

To address these challenges, Gulf Oil’s Chennai facility partnered with IUS Equipment Pvt. Ltd. to implement a fully automated blending and dual pigging system. The project successfully transformed the plant into a modern, efficient, and data-driven production facility while significantly improving safety, traceability, and process reliability.

Project Overview

Client: Gulf Oil Ltd.
Location: Chennai, Tamil Nadu, India
System Type: Automated Blending & Dual Pigging System
Product: Lube Oil Additives
Line Size: 3 Inches
Number of Lines: 1
Source Tanks: 1
Destination Tanks: 2

Challenges Faced by Gulf Oil Chennai

Prior to automation, the Chennai facility relied on a manual blending and material transfer process. While functional, the system presented several operational challenges:

• Cross-contamination between product batches
• High pipeline hold-up resulting in product loss
• Inaccurate additive dosing and blending inconsistencies
• Extended cleaning and batch changeover times
• Excessive manual intervention
• Safety concerns associated with manual handling
• Lack of automated batch recording and traceability

These challenges not only affected productivity but also increased operational costs and quality control risks.

Project Objectives

The primary objectives of the automation project were:

1. Eliminate Cross-Contamination

Ensure clean product transfer between batches and maintain consistent product quality.

2. Maximize Product Recovery

Reduce material wastage by minimizing pipeline hold-up.

3. Improve Dosing Accuracy

Automate additive dosing and blending operations for precise measurements.

4. Reduce Batch Changeover Time

Implement an efficient cleaning system to improve production output.

5. Enhance Operator Safety

Reduces manual handling and creates a safer working environment. Also, enables automated batch recording, reporting, and documentation.

IUS Equipment’s Automation Solution

To achieve these objectives, IUS Equipment Pvt. Ltd. designed and implemented a comprehensive automated blending and pigging system.

Fixed Pipeline Network Installation

The existing hose-based transfer system was replaced with a fixed MS pipeline network incorporating long-radius 5D elbows.

This upgrade delivered:

• Leak-free operation
• Reduced contamination risks
• Lower maintenance requirements
• Improved process reliability

Automated Dual Pigging System

A fully automated dual pigging system was installed with dedicated launching and receiving stations.

Key features included:

• Actuated valves and instrumentation
• High-density polyurethane pigs
• PLC-controlled operation
• HMI-based monitoring and control
• Automated interlocks for safe operation

The pigging system significantly reduced residual product remaining inside pipelines and ensured maximum material recovery during product transfers.

Advanced Valve Technology

Three-way fully actuated T-port valves were installed throughout the system to eliminate dead zones and residual material accumulation inside valves.

This helped maintain product purity and supported faster batch transitions.

6. Establish Complete Traceability

Automated Blending System

An agitator equipped with a Variable Frequency Drive (VFD) was installed on the blending tank.

Benefits included:

• Uniform mixing of base oils and additives
• Controlled agitation speeds
• Consistent blend quality
• Improved process flexibility

Load Cell-Based Dosing System

Accurate additive dosing was achieved through load cell integration.

The system provided:

• Real-time weight monitoring
• Automatic dosing control
• Precise batch measurements
• Reduced human error

PLC logic ensured automatic stopping and batch completion based on predefined recipes.

Batch Traceability and Data Recording

To improve quality assurance and compliance, IUS integrated an automated batch recording and reporting system.

The solution enabled:

• Real-time production data collection
• Automatic batch documentation
• Report generation and printing
• Complete process traceability

Enhanced Operator Safety

A specially designed skid system featuring ergonomic barrel placement and funnel arrangements was installed.

This reduced manual handling requirements while improving operational safety and workflow efficiency.

Results Achieved After Implementation

Following installation and commissioning, Gulf Oil conducted operational trials and reported substantial performance improvements.

Near-Complete Product Recovery

The automated pigging system recovered nearly all residual product from transfer pipelines, significantly reducing material wastage.

Faster Cleaning and Changeovers

Reduced pipeline hold-up enabled quicker cleaning cycles and shorter batch transition times.

Elimination of Cross-Contamination

The combination of automated pigging, fixed pipelines, and advanced valve technology effectively eliminated batch contamination issues.

Improved Dosing Accuracy

Load-cell-based automation ensured precise additive measurement and consistent product formulation.

Increased Productivity

Reduced manual intervention and automated process control improved overall plant throughput.

Improved Workplace Safety

Automation minimized operator exposure to manual handling activities and reduced operational risks.

Significant Cost Savings

The facility benefited from:

• Lower product losses
• Reduced maintenance costs
• Less rework
• Improved resource utilization

Complete Batch Traceability

Automated data logging and reporting provided full visibility into production operations and quality control processes.

Enhanced Process Reliability

The integrated PLC-HMI platform improved monitoring, control, and operational consistency across the facility.
