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.

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…

Ammonia as an Energy Carrier – Update from the Netherlands

Proton Ventures specializes in ammonia and energy related matters in four ways: Terminal storage and handling (bulk) NFUEL Small scale ammonia production DeNOx and N2O removal systems Battolyser Technology (electrolysis and battery storage in a single appliance) Recently, Proton Ventures welcomed new venture capital from Koolen Industries allowing further growth, development and market penetration of the new small scale ammonia production technology. Momentum is increasing: across the globe, we have some great leads in various stages of development. Can multiple small scale production trains actually be a smart solution for the larger production capacity requirements when fluctuation of either the…

Optimizing Absorptive Separation for Intensification of Ammonia Production

High pressure requirements of Haber-Bosch process imposes substantial operating (e.g., compression) and capital (compressor cost, advanced costly alloys, thick reactor casing, etc.) expenses in the ammonia production. Cost considerations force ammonia producers to take advantage of the economy of scale to drive down the manufacture cost, while small and energy-efficient processes that can be powered with off-grid renewable energy are required for ammonia-mediated hydrogen economy. Small-scale reaction-absorption process is proposed to be a viable technology to reduce the operating pressure requirements of Haber-Bosch process.1–4 Here, we present an overview of our efforts to further intensify ammonia production via reaction-absorption process.…

RAPID: supporting modular manufacturing and process intensification for small-scale ammonia

Using greener feedstocks at low pressures and temperatures, with higher conversion rates and less greenhouse gases is considered a pipe dream. The technology and equipment simply wasn’t available ... until now. The case for small-scale, energy efficient ammonia production is well documented, but access to funds may not be. Now, Manufacturing USA and the Manufacturing Extension Partnership may offer a new path to success.

Advances in Making High Purity Nitrogen for Small Scale Ammonia Generation

The presentation will address recent developments in the Solar Hydrogen Demonstration Project in which hydrogen, nitrogen and ammonia are made from solar power, water, and air; and used to fuel a modified John Deere farm tractor. In industrial applications very pure nitrogen is made by cryogenic distillation of air. Using Pressure Swing Absorption systems alone it is extremely difficult to achieve the required purity. An improved method was developed for making high purity nitrogen, for smaller systems. Will discuss how, when Oxygen contaminates the reactor catalyst, Hydrogen is used to purge the catalyst, and subsequently used as fuel.

Scale up and Scale Down Issues of Renewable Ammonia Plants: Towards Modular Design

Renewable sources of energy such as biomass, solar, wind or geothermal just to mention some of the most widely extended are characterized by a highly distributed production across regions (EPA, 2017). Total renewable energy available is more than enough to provide for society needs, but the traditional production paradigm is changing. Economies of scale have featured current industry and its infrastructures based on large production complexes (i.e Dow, Exxonmobil or BASF hubs). The well-known six tenths rule has extensively been used in the chemical industry to scale up or down the cost of technologies. This rule is suitable for large…
