DVLS Butadiene Analyzer

1,3-Butadiene is used to produce synthetic rubbers, nylon and plastics. As Butadiene contains approximately 100 ppm inhibitors and also forms Butadiene Dimer it is essential to control all product specifications. Da Vinci Laboratory Solutions introduces the All-In-One Butadiene Analyzer that determines the complete product specifications in a single run; including the hydrocarbon composition, impurities such as Dimer, inhibitors and other impurities.

Analysis of Composition and Impurities in Butadiene, Crude C4 and Raffinate

The All-In-One Butadiene Analyzer is based upon the Agilent 8890 Gas Chromatograph (GC) and consists of two channels. Each channel is configured with its own sampling technique and detector. The dual channel configuration enables a simultaneous analysis of the Butadiene specifications within 30 minutes. 
The front channel is configured with a Liquid Sampling Valve and/or a Gas Sampling Valve for the analysis of:

• Hydrocarbon impurities at ppm level;
• Butylene/Crude C4/1,3-Butadiene/Crude Butadiene/Raffinate composition.

The back channel is configured with a Liquefied Gas Injector for the analysis of:

• Dimer and Styrene content;
• TBC and EC3071 Inhibitors;
• Residual solvents such as BHT Inhibitors, NMP, DMF, Toluene and Acetonitril..

Het ontwerp van het station omvat vier afzonderlijke monsterinlets om kruisbesmetting te voorkomen en een gecontroleerde vacuümpomp voor bemonstering onder de omgevingstemperatuur van 100 tot 1000 mBar. Het station is ook corrosiebestendig voor monsters met hoge concentraties waterstofsulfide.
Het Gasmonsternamestation wordt aangestuurd door de Time scheduler-software. Deze tool wordt gebruikt om de pre-analyse bemonsteringsvolgorde en de bijbehorende GC-analyse in de CDS te programmeren.
