Optimizing absorption to improve Haber-Bosch synthesis

Ammonia absorber columns offer an alternative separation unit to replace condensation in the Haber-Bosch synthesis loop. Metal halide salts can selectively separate ammonia from the reactor outlet gas mixture and incorporate it into their crystal lattice with remarkably high thermodynamic capacity. While the salts’ working capacity can be limited and unstable when they are in their pure form, the capacity is stable and can be high when using a porous silica support. Here, we discuss optimal conditions for uptake and release of ammonia. The production capacity (ammonia processed per unit absorbent and per unit production time) depends on processing parameters…

Next Generation Technology Integration Platform for Low- and Zero-Carbon Ammonia Production and Utilization

RTI International and its partners are developing a Technology Integration Platform (TIP) to demonstrate next-generation technologies for ammonia (NH3) production and utilization in a modular testbed as part of U.S. Department of Energy ARPA-E’s REFUEL+IT program. The objective of this effort will be to demonstrate the use of NH3 for long duration energy storage, as a fuel, and a hydrogen (H2) carrier.  The TIP, which will be housed at the University of Minnesota West Central Research and Outreach Center’s operational hybrid wind and solar test site, will integrate several breakthrough technologies developed in the REFUEL program to demonstrate an advanced…

Tsubame BHB Launches Joint Evaluation with Mitsubishi Chemical

Last month Tsubame BHB, a Japanese developer of ammonia synthesis technology, announced the signing of a “joint evaluation contract” with Mitsubishi Chemical Corporation (MCC) that will focus on a novel ammonia separation membrane. The company, which started operations in 2017, is working on a method of ammonia synthesis that could allow economic production at scales 1-2 orders of magnitude below today’s plants.

Observations on green ammonia production scaleup and the potential for job creation

Green ammonia provides Australia with the opportunity to export our abundant renewable resources.  A key benefit to the nation is the jobs created in an expanded ammonia export industry, allowing transition from carbon-based energy to cleaner sources. Drawing on cases study analysis of green ammonia plants scaled from 25 to 2500 tonnes of ammonia per day, the impact of a range of production cost elements is assessed focusing on ammonia production.

Small-Scale Ammonia Synthesis Technology on Track for 2021

On October 6, 2019, the Nihon Keizai Shimbun published an article that confirmed a goal set at the 2017 launch of Japanese chemical technology developer Tsubame BHB. The goal is to have Tsubame’s ammonia synthesis technology ready for licensing in 2021. According to Tsubame’s English-language Web site, its technology “makes it possible to produce ammonia even at small-scale plants” – good news for ammonia energy project developers interested in distributed production concepts.

Ammonia Absorbents with High Stability and High Capacity for Fast Cycling

Ammonia absorption is an alternative separation to condensation in ammonia production. Metal chloride salts selectively incorporate ammonia into their crystal lattices with remarkably high capacity. Regeneration and stability of these salts are further improved by dispersing them onto a porous silica support. Here, we discuss the optimal preparation methods of supported metal halides, as well as optimal conditions for uptake and release of ammonia. The metal halide salt particle size, support particle size, support composition and preparation methods are optimized for material stability, speed of uptake and release, and maximum ammonia capacity. An automated system was used to rapidly screen…
