凯茵化工讯 11月14日，特种化学品制造商科莱恩宣布与美国三角国际研究中心(RTI International)签署 全Q许可协议，授权科莱恩为RTI 提供固体脱硫剂材料，该脱硫剂对RTI的高温合成气脱硫工艺(WDP)技术至关重要。

　　作为一种成熟的先进技术，高温合成气脱硫技术可以利用煤炭和其它高硫原料生产出更加清洁的能源和化学品。该技术可使在煤炭或石油焦气化产生的合成气等含硫气体流在高温(250-650℃)下直接脱硫，从而降低大量合成气冷却和热回收的能耗。与传统技术相比，W美国陶氏防霉杀菌剂KATHON®LXEDP技术从整体上提高流程的效率，减少温室气体的排放，好高可将整个气体净化模块的支出和运营成本降低50%。

　　科莱恩的固体流化吸附剂反应迅速，具备较高的硫吸附能力，可在宽范围的操作温度和压力下，将硫化氢(H2S)和羰基硫(COS)脱除至极低的水平，并且有能力处理大流量的合成气。由于该吸附剂具有可再生性，且损耗率低、循环周期长，因此几乎无需替换，从而减少设备停车频率。该产品将被纳入科莱恩吸附剂系列，成为原本种类广泛、高度成熟的合成气催化剂与吸附剂产品线的关键补充，为满足日趋严格的行业要求提供综合解决方案。

　　WDP技术采用创新的输送反应器设计，并使用独特的高容量、可再生、耐损耗的高性能固体脱硫剂。该技术可以在高达650 C的温度下脱除多种含硫组分，合成气中总硫含量脱除率高达99.9%。该工艺已在美国佛罗里达州坦帕电力公司波尔克电站的煤炭/石油焦气化厂的5.4万标方/小时的合成气装置中得到了验证，运行时间超过3500个小时。

　　通过与下游活性胺的碳捕获工艺相结合，该技术可使合成气中的总体含硫量浓度进一步降低至ppm水平(好低可达到100ppb水平)，可适用于下游化学品、化肥和燃料等对气质有严格要求的应用。

Clariant signs contract with RTI to supply solid desulfurizer

凯茵 化工 News Clariant, a specialty chemicals manufacturer, announced on November 14 that it has signed a worldwide license agreement with RTI International to authorize Clariant to supply solid desulfurizer material to RTI exclusively RTI's High Temperature Syngas Desulfurization Process (WDP) technology is crucial.

As a sophisticated advanced technology, high-temperature syngas desulfurization technology can use coal and other high-sulfur feedstock to produce cleaner energy and chemicals. This technology allows direct desulfurization of sour gas streams such as syngas from the gasification of coal or petroleum coke at elevated temperatures (250-650 ° C), thereby reducing the energy consumption of large volumes of syngas for cooling and heat recovery. Compared to traditional technologies, WDP technology as a whole to improve the efficiency of the process to reduce greenhouse gas emissions, up to the entire gas purification module spending and operating costs by 50%.

Clariant's solid fluidized adsorbents react rapidly with high sulfur adsorption capacity to remove hydrogen sulfide (H2S) and carbonyl sulfide (COS) over a wide range of operating temperatures and pressures To extremely low levels, and capable of handling large amounts of syngas. Because of the regenerability of the adsorbent, low loss and long cycle times, there is little need for replacement, reducing plant downtime. The product will be incorporated into the Clariant sorbent range as a key addition to the original wide range of highly mature syngas catalyst and sorbent product lines that provide comprehensive solutions to meet increasingly demanding industry requirements.

WDP technology uses an innovative transport reactor design and unique high-capacity, renewable, wear-resistant, high-performance solid desulfurizer. The technology removes many sulfur-containing components at temperatures as high as 650 ° C. The total sulfur removal in the syngas is as high as 99.9%. The process has been validated at a 54,000 Sq. / H syngas unit at the coal / petrol gasification plant at Polk Power Station in Tampa, Florida, United States for more than 3,500 hours.

This technology enables a further reduction of the overall sulfur concentration in syngas to ppm levels (down to 100 ppb levels) by combining with the carbon capture process of the downstream reactive amines, which can be applied to downstream chemicals , Fertilizers and fuel on the temperament have strict requirements of the application.
