2019-10-24 · 2019-10-24 · A new way of removing carbon dioxide from a stream of air could provide a significant tool in the battle against climate change. The new system can work on the gas at virtually any concentration level, even down to the roughly 400 parts per million currently found in the atmosphere.
2021-4-5 · 2021-4-5 · The G3 is one of the quietest portable oxygen concentrators available, but this efficient device has a lot more going for it. It boasts a four-hour battery life and an operational altitude of up to 10,000 feet, and the carrying case looks more like an outdoorsy lunch bag than a medical device.
Solar concentrators are classified into four categories based on their optical characteristics, such as the concentration ratio, focal shape, and optical standard. These concentrators can be single-axis tracking or two-axis tracking to the sun as follows: 1. parabolic-trough concentrator (PTC); 2.

Clean Coal Dewatering: The 13-0.5mm clean coal in pit is first dewated by bucket elevator, secondly dewated by centrifuge machine, and then transported to the clean coal storage yard by belt conveyor as the final product together with the clean coal on the screen. Flotation: The overflow from the pit enters the flotation feed pool and is pumped to the pulp preprocessor through the slurry pump.
2016-2-29 · The process let to recover fine gold which is difficult to be recovered by gravimetric devices, and the coarse gold can be recovered from gravimetric concentrates. Thus, the process is an alternative to amalgamation and cyanidation. The process can be employed in small or big scale. The short time in reactors, let to have lower capital cost.
