Fast & Automated Alternative Method to Traditional Detailed Hydrocarbon Analysis (DHA) - VUV Analytics

Introduction

A talk from the Chemicals Summit - Hydrocarbon Processing Symposium

The characterization of hydrocarbon streams, including speciation and quantitation, has traditionally been accomplished using Detailed Hydrocarbon Analysis, or DHA, by gas chromatography (GC) with a flame ionization detector (FID) for a GC-FID configuration. Although this achieves very good chromatographic separation, the technique requires long run times and significant manual review of data, traditional DHA has changed since it was first introduced over 40 years ago. Verified Hydrocarbon Analysis™(VHA) is a modern approach to traditional DHA using GC - Vacuum Ultraviolet Spectroscopy (VUV) and spectral validation to characterize complex hydrocarbon streams – accurately, without the need for human intervention, and in a fraction of the time of traditional DHA. This presentation describes the technology and method required to successfully implement VHA.
