Coking Solid Quinoline Insoluble Matter Tester – Enhancing Throughput And Safety

Coking Solid Quinoline Insoluble Matter Tester – Enhancing Throughput and Safety

Throughput Considerations
To increase laboratory capacity, Changsha Friend Experimental Analysis Instrument Co., Ltd designs QI testers with multi-reactor configurations, allowing up to four simultaneous runs. Programmable cycles stagger start times, ensuring continuous operation without operator intervention.

Automation Features
Software-driven scheduling, automated cooling, and solvent recovery modules reduce manual steps. Integrated sensors monitor pressure, temperature, and agitation speed, triggering alarms and shutdown procedures upon deviation from setpoints.

Safety Protocols
High-temperature operations with toxic solvents demand rigorous safety features: pressure relief valves, double-wall reaction vessels, and sealed sampling ports. Exhaust capture systems neutralize quinoline vapors, complying with occupational exposure limits.

Maintenance Strategies
Regular inspection of reactor seals and pressure gauges prevents leaks. Clean solvent lines with compatible solvents to avoid blockages. Replace PTFE tubing annually to maintain chemical resistance and flexibility.

Interpreting QI Trends
Plot QI values over time for each feedstock batch to detect gradual increases that may indicate catalyst deactivation upstream. Pair QI results with elemental analysis (e.g., sulfur, nickel) to refine blending strategies and optimize processing conditions.
