SGAO丨Chlorine Chemical Online Analysis System Helps Boost Smart Transformation

2026-04-21 15:34:09

At a crucial stage where the chlor-alkali industry is moving towards green transformation and high-quality development, companies are demanding more and more accuracy, smarter technology, and better safety and environmental compliance in testing.

Traditional manual testing has hit a development bottleneck:

· It takes hours to test and can't respond in real-time

· Human errors are high and data consistency is poor

· There can be up to 100 sample points

· Disposing of samples poses environmental risks

· It's hard to support efficient operation of equipment and process optimization

Based on real industry pain points, Gao (Beijing) Intelligent Technology is helping Tianwei Chemical Factory deploy an online smart vinyl chloride detection solution, pushing the testing method from 'manual experience' to 'systematic intelligence'.

Full system intelligent linkage, reshaping the inspection process

Addressing challenges like vinyl chloride being prone to polymerization, highly corrosive, having many sampling points (100), high environmental risks from sample discharge, and poor stability when benchmarking lab data.

SGAO (Beijing) Intelligent Technology has partnered deeply with global analytical instrument leader Agilent Technologies to create a complete technical framework centered on the 'QC smart platform, sample pre-processing system, online explosion-proof gas chromatograph, and explosion-proof analysis cabin.' This setup enables a full closed-loop management process from sample collection, pre-processing, and analysis to data transmission and safety alerts.

QC Intelligent Platform

Building an unmanned analysis hub

As the control core of the system, the QC smart platform integrates an independent software operating system and has the following technical capabilities:

✅ Full system collaboration

Achieve two-way data exchange and linked control with the analysis station, alarm system, and various detection units.

✅ Real-time status monitoring

Monitor the sample’s pressure, temperature, flow, and equipment status online, with automatic alerts for any issues.

✅ Intelligent process scheduling

Automatically carry out sample replacement and injection switching according to preset logic, and sync analysis data in real time to the DCS and LIMS systems, making the analysis process unmanned and data flow automated.

Preprocessing System

Ensure the samples are genuine and eco-friendly

The reliability of the sample pretreatment step directly determines the accuracy of the analysis results. This system is specially designed for the operating conditions of chlor-alkali process pipelines:

✅ Material & Craft

The sampling pipeline is made entirely of PTFE material with a seamless design, eliminating any risk of leaks from the source.

✅ Multitasking

Supports rotational analysis of 100 points, with a single-sample analysis cycle of ≤5 minutes. All sampling purge gas is recovered back into the production system, achieving zero external discharge of samples.

✅ Weather resistance adaptability

Equipped with electric heating and self-regulating temperature technology, it ensures that the sampling temperature stays above 5°C even in extreme -40°C conditions, keeping the sample stable.

✅ Efficient Circulation and Recycling

The acid-resistant corrosion sampling pump allows real-time circulation of sample gas and can clean the filter to effectively remove particles.

Online GC system

Achieve high-precision simultaneous analysis of multiple components

As the core analysis unit of the detection system, this instrument is deeply optimized for the characteristics of vinyl chloride samples:

✅ Corrosion-resistant design

The multi-sample valve is made of Hastelloy, and its flow path has a built-in anti-corrosion coating, so it can withstand acidic gases for a long time.

✅ chromatographic separation capability

A dedicated chromatographic column can simultaneously analyze multiple components like acetylene, hydrogen chloride, vinyl chloride, and moisture.

✅ Detection accuracy

The absolute deviation for acetylene testing is less than 0.2%, for hydrogen chloride less than 0.5%, and for vinyl chloride less than 1.0%. The reliability of the analysis data is significantly better than the usual industry standards.

✅ The benchmarking results are excellent

The online test data matches the lab test data very closely, with small deviations, and the accuracy meets the requirements.

Explosion-proof analysis station

Building a secure analysis environment

Integrate the analysis unit into the explosion-proof analysis cabin to physically separate the detection process from the personnel's operating space:

✅ Main positive pressure explosion-proof

Keep the internal pressure higher than the outside to prevent flammable gases from coming in;

✅ Multi-parameter alert

Integrated combustible gas detectors, toxic gas detectors, low-oxygen gas detectors, and audible and visual alarm systems;

✅ Remote visual monitoring

The explosion-proof video surveillance system supports 24-hour real-time inspections, improving response efficiency to abnormalities.
