Bench Scale Evaluation of the IntraMicron Desulfurization Technology Suite

The IntraMicron Desulfurization Technology Suite (IM-DTS) is an innovative sulfur removal and recovery system that was developed to address the current need for scalable desulfurization technology for a variety of feedstocks including but not limited to natural gas, biogas, landfill gas, frac gas, petroleum gas, refinery off gas, flare gas, syngas, as well as gasified biomass, coal, and municipal solid waste (MSW).  IM-DTS is the synergistic combination of a selective catalytic oxidative sulfur removal (OSR) stage that transforms up to 99% of sulfur contaminants (H₂S, COS, mercaptans, etc.) into elemental sulfur using a proprietary, patent-pending catalyst and a polishing adsorbent bed equipped with an in-situ bed-life capacity sensor (BLS) that enables optimal adsorbent bed operation and cycling.  IntraMicron’s OSR catalyst does not produce significant amounts of SO₂, even in the presence of a high concentrations of oxidizers and is tolerant to numerous contaminants (halogens, NH₃, etc.).   IntraMicron’s BLS optimizes the polishing adsorbent step of the process by providing an indication of the remaining capacity in the adsorbent bed.  IM-DTS was evaluated at the bench scale to determine its performance at a wide range of experimental conditions with the goal of assisting in determining process economics and appropriate scaling parameters.  The results of the bench-scale evaluations were used in conjunction with process simulations to show that IM-DTS can provide up to a 75% reduction in total life cycle desulfurization cost compared to current state of the art desulfurization technologies at several scales.
