Abstract: Methods of the present disclosure may comprise: introducing a first effluent and a second effluent in a gasifier of a partial oxidation unit to produce a waste gas, wherein the first effluent comprises one or more hydrocarbon containing feeds and the second effluent comprises air, enriched air with oxygen or oxygen; selectively removing hydrogen sulfide (H2S) from the waste gas; combining the waste gas and steam in a water-gas shift unit to produce a shift gas comprising hydrogen and carbon dioxide; separating the carbon dioxide from the shift gas in a carbon capture unit to produce a carbon dioxide-enriched effluent and an effluent comprising a hydrogen- and nitrogen-enriched mixture; and recovering the carbon dioxide from the carbon dioxide-enriched effluent.

Abstract: Improved steel welds, article for making the same, and methods of making the same are provided. The present disclosure provides advantageous erosion, corrosion and/or cracking resistant weld metal. More particularly, the present disclosure provides high manganese (Mn) weld metal compositions having enhanced erosion, corrosion and/or cracking resistance, articles for the production of the high manganese weld metal compositions having enhanced erosion, corrosion, and/or cracking resistance, and methods for fabricating high manganese weld metal compositions having enhanced erosion, corrosion and/or cracking resistance.

Abstract: A gas-liquid catalyzed reaction is performed by introducing at least a portion of the reactive gas into the catalyst as a cross-flow or radial-flow stream. Introducing at least a portion of the reactive gas as a radial flow stream allows the reactive gas to travel through the catalyst bed along a shorter path length. This reduces the pressure drop for the radial flow portion of the gas. The reactive gas can be introduced into the catalyst bed at various heights relative to the height of the catalyst bed.

Abstract translation: 通过将至少一部分反应性气体作为交叉流动或径流流引入催化剂来进行气液催化反应。 将反应性气体的至少一部分引入作为径向流动流允许反应性气体沿着较短的路径长度行进通过催化剂床。 这降低了气体的径向流动部分的压降。 反应气体可以相对于催化剂床的高度以各种高度引入催化剂床。
