2018032 SLURRY HYDROGEN SULFIDE REMOVAL PROCESS

A new sulfur removal process utilizing traditional iron oxide in a very unique way.  The process produces a highly effective technology to completely remove H2S and eliminate acid gas disposal, liquid chemical management and other environmental challenges.

The process is based on a proprietary granular BrimsorbTM F. The granules are mixed with water to form a slurry that comes into contact with H2S-laden gas.  The process is simple to operate, has a small footprint, and has VERY low capital and operating costs. The regenerable nature of the adsorbent reduce operating costs, but the non-hazardous elemental sulfur and iron oxide byproduct can easily be disposed of thereby minimizing any environmental impact.
Compared to the traditional liquid processes and Sulfur Recovery Units:

1. Adsorbent Capacity: the adsorbent is a proprietary amorphous hydroxyl iron oxide, which is regenerable thereby having high sulfur removal capacity.
2. Environmentally friendly: the slurry can be regenerated which reduces the wastewater discharge, and eliminates the secondary pollution caused by by-products in competitive processes.
3. Wide range of process applications: this process is also suitable for removing H2S from biogas, coke oven gas, associated gas, natural gas, gaseous and liquid streams from petrochemical industry. 
Presentation will explain a new environmentally sound option for treating high H2S natural gas that can reduce capital and operating expense.
