High capacity scrubber medium to remove hydrogen sulfide

本发明涉及废水处理和石油工业由于其生产过程而产生剧毒气体硫化氢的挑战。目前用含有腐蚀性和氧化剂的洗涤液捕获和去除硫化物的方法和产品在洗涤器化学和废洗涤器材料的处理方面存在问题。该解决方案涉及一种银(Ag+)壳聚糖片状复合材料，它可以从空气和液体中去除硫化物，并将废介质转化为可用的产品。壳聚糖片是从虾和其他甲壳类动物壳中提取的廉价的天然线性多糖。 这项技术的目标市场是石油行业和涉及废水处理的行业。 该技术的可能应用包括： -作为接触硫化氢气体区域的空气过滤口罩的有效成分，作为具有视觉指示器的两级顺序过滤系统，为处于硫化氢有毒水平可能构成致命风险的环境中的工人提供潜在的安全保障。 -作为一种去除低硫燃料中剩余硫的方法。 这项创新的技术优势是： -与其他硫化物去除方法相比，具有成本效益和环境友好性。 -适用于气体和液体材料，实现近100%的硫化物脱除。 -该过程产生的最终废物产生的材料可以作为肥料的添加剂或土壤改良剂重新使用，以及可以添加到涂料、树脂和混凝土中以提供抗菌性能的物质。

The invention pertains to the challenge of wastewater treatment and petroleum industries production of a highly toxic gas, hydrogen sulfide, as a result of their production processes. Current methods and products to capture and remove sulfides with scrubbing liquids containing caustic and oxidizing agents have issues with the scrubber chemistry and disposal of spent scrubber materials. The solution involves a silver (Ag+) chitosan flake composite that removes sulfide from air and liquids with the spent medium converted into usable products. Chitosan flakes are readily available, inexpensive, natural linear polysaccharide obtained from shrimp and other crustacean shells. The target market for this technology are petroleum industries and industries involved in wastewater treatment. Possible applications for the technology include: - As an active ingredient in air filter masks in areas exposed to hydrogen sulfide gas as a two stage sequential filter system with visual indicators that provides potential increase to safety for workers in environments where toxic levels of hydrogen sulfide can pose a lethal risk. - As a method of removing the remaining sulfur in low sulfur fuels. Technology advantages of this innovation are: - Cost effective and environmentally friendly compared to other sulfide removal methods. - Applicable to both gaseous and liquid material achieving nearly 100% sulfide removal. - The end waste product from the process creates materials that can be re-used as an additive to fertilizer or as a soil enhancer as well as substance that can be added to paints, resins, concrete to provide antibacterial properties.
