Control H2S in Refinery Propane/ Propylene Mix using Tunable Diode Laser technology.
Propnae/Propylene Mix: MIX There are three major sources of pure Propylene for polypropylene feed: Refinery Fluidized Catalytic Cracking (FCC) byproduct, Ethylene Cracking Furnaces as a byproduct of Ethylene production and Propane dehydration; of these three, Refinery FCC byproduct is by far the largest source.
Sulfur compounds in the feed to the FCC unit are converted to H2S and follow the Propane/Propylene product. Depending on the processing, there are three different products: an essential pure Propane, a 65/35 mix of Propane/Propylene and a 35/65 Propane/Propylene mix (see stream composition table). These products are further refined for their eventual use.
Critical Control of H2S: H2S The primary method of H2S control is removal in the stripper section of the vapor recovery unit.
Traditional Measurement Solutions: Lead Acetate paper tape analyzers have been used but they require frequent replacement of the paper tape and many regard the paper tape itself as a handling and disposal problem due to its lead content. Gas Chromatographs have often been used but the desired measurements require Flame Photometric and other trace sulfur detectors that can be maintenance intensive.
SpectraSensors' Solution: The SpectraSensors SS2100 off ers a new solution to this challenging measurement. There are no cylinder gases or Lead Acetate tapes to replace on a routine basis, so the analyzer is very low maintenance and has a low cost of ownership over the life of the analyzer. The high resolution that is inherent to TDL technology eliminates errors due to interferences that have hampered other spectrometric approaches.
Only SpectraSensors employs Differential Spectroscopy to cope with the changes in background spectrum of the sample caused by changing operating conditions and feedstocks. The sample gas is passed through a copper nanoparticle scrubber to remove H2S, and the spectrum of the H2S-free sample is measured. The scrubber is then bypassed to measure the raw sample with H2S, and the H2S is measured by spectral subtraction. As the H2S-free background spectrum can be applied repeatedly to the sample, the scrubber is only used as needed, controlled by logic in the electronic controller.
The scrubber lifetime in normal service is a minimum of 18 months, so consumable costs and maintenance are low. Tunable Diode Laser technology means that analysis is fast; results can be updated every second if desired.
Key Features:
- Low Cost of Ownership – No Lead Acetate paper tape, carrier gases or flame fuel to buy
- No interference from changing background compounds – uses high resolution TDL and Differential Spectroscopy Technology
- Virtually maintenance free – No routine maintenance required
- Fast – Sensitive measurement of H2S
