Small-scale distillation processes have specific concerns that are different than commercial-scale distillation. Presented here are several topics, including column internals and column-sizing software, considered from the perspective of pilot-scale distillation The design and operation of laboratory- and pilot-scale columns are…
In November 2023, Heirloom Carbon Technologies (Tracy, Calif.; www.heirloomcarbon.com) unveiled the United States’ first commercial direct air capture (DAC) facility, which can capture up to 1,000 ton/yr of CO2. The process first uses renewable energy to remove CO2 from limestone…
In November 2023, the first commercial test was initiated for a novel, fouling-immune membrane for brackish-water reverse osmosis (BWRO) applications through an early-access program. Membrane developer ZwitterCo (Woburn, Mass.; www.zwitterco.com) says its membrane is fouling-immune in cases where fouling of…
Properly locating a simple 1–2-in. balance line can make all the difference in successful reboiler operation Steam reboilers are crucial to production in petroleum refineries and petrochemical plants, representing huge capital investment in distillation columns. Regardless of the investment made…
Direct-air capture (DAC) of atmospheric carbon dioxide presents promise for helping to reach global-warming reduction goals. However, many DAC technologies are hindered by high costs and inefficiency. RepAir Carbon (Yokne-am Illit, Israel; www.repair-carbon.com) recently launched a field prototype of its…
Capturing natural gas from petroleum drilling wells is economically challenging, but would have positive environmental impacts because it would eliminate the need for flaring and could allow the hydrocarbons to be converted into useful chemicals. Now, research led by chemists…
The extremely high material purity demanded for conventional lithium-ion battery manufacturing creates considerable costs for transporting and refining lithium and other raw materials. Through the development of a single-step electroplating process that uses lower-purity raw materials and a nanostructured-foam electrode…
A new ammonia-recovery plant has begun steady-state operation to demonstrate a patented process to upcycle the ammonia content from cattle manure into stabilized fertilizer ingredients. The Ammonia Recovery System (ARS) was developed by Bion Environmental Technologies, Inc. (Old Bethpage, N.Y.;…
A process to produce an alternative to palm oil for food applications, developed by scientists at Nanyang Technological University, Singapore (NTU Singapore; www.ntu.edu.sg), will be scaled up for commercial production through a partnership with Eves Energy Pte. Ltd. (Singapore; www.eves-energy.com).…
Tailored separation systems address energy consumption and fouling while supporting sustainability Recently there has been a demand for separation technologies that are better suited to specific applications and a more sustainable world, so providers of filters and membranes have begun…
