Angstrom Advanced Hydrogen Generating Plant by Pressure Swing Adsorption with Purifying System

Angstrom Advanced Hydrogen Generating Plant by Pressure Swing Adsorption with Purifying System
For more information please call Angstrom Advanced at: 781.519.4765

Introduction
Angstrom Advanced Pressure Swing Adsorption (PSA) is used to separate hydrogen gas from other gases by feeding the gas under certain pressure. This separation process occurs in adsorption tower. The main advantages behind this technology is its low cost, low capacity, minimal maintenance requirements and a user-friendly interface. The H2 Purifying System removes oxygen from Hydrogen via a catalyst to get high purity H2 after adsorption of drying through the dust filter. The system can remove oxygen levels down to 1ppm. Through one step of purification, the purity can reach to 99.999~99.9999% and dew point can be lower than -70°C; Through a second purification step, O2 can be lowered down to less than 0.1ppm and dew point can be lowered to -90°C.
Specifications
H2 capacity10-5000 Nm3/h
Dew Point≤-60C
H2 purity %>98-99.999%
Work pressure0.2-4.0MPa
PSA Process Overview
Pressure-Swing Adsorption or PSA is a technical process widely used these days in various Angstrom Advanced gas production applications. It’s a typically non-cryogenic way of purifying gas. PSA process differs from cryogenic techniques of gas separation as it can function under near-ambient temperatures. Under pressure, the PSA process separates some ‘species’ from a mixture, according to the molecular characteristics of those ‘species’. This is because different gases has the propensity to be attracted to different solid surfaces more or less strongly.More gas is adsorbed at higher pressure while the gas is desorbed as the pressure is reduced. Suppose air under pressure is passed through a vessel containing an adsorbent bed and this bed has the property to attract nitrogen more strongly than oxygen. What will happen is that a part or all of the nitrogen will remain in the bed, while the gas coming out of the vessel will be enriched in oxygen. As the bed reaches its optimum capacity to adsorb nitrogen, it can again be regenerated by reducing the pressure. Releasing the adsorbed nitrogen in the process. Thus readying itself for another cycle of oxygen enriched air. This cycle goes on. Popular adsorptive materials like carbon, zeolites, silica etc. are used as the adsorbent beds. They selectively adsorb the undesired gases at high pressure on their surface. Continuous production of the target gas is achieved by using more than one adsorbent chamber. However it is not a very easy process and difficult to model accurately. But once properly modeled, adsorption process can result in complex diffusion relationships.

Angstrom Advanced Nitrogen Generating Plant by Membrane Separation

Angstrom Advanced Inc. designs, manufactures and supplies variety of scientific instruments and Hydrogen & Nitrogen plants for academic and industrial fields.k
Introduction
In this setup by Angstrom Advanced, the compressed air compressor filter into the polymer membrane filters, a variety of gas in the film in the solubility and proliferation of different factors, leading to different gases in the membrane penetration rate in a relatively different. According to the characteristics, various gases can be divided into “rapid gas” and “slow gas”. After being compacted and purified (to remove oil, water and dust) the air will enter the membrane separation to separate. First, the O2, CO2 and some vapor will infiltrate into the membrane wall and then exit through the discharge port by air pressure; since the infiltrating speed of N2 is slower, it will flow out from the gas collector at the end of the pressure box and finally enter nitrogen buffer tank.

SUSTAINABLE… FASHION? RENEWABLE ENERGY CLOTHING DESIGNED TO CHARGE YOUR CELL PHONE

Brilliant! After all, a mobile device is intended to be just that – mobile. Why is it that we can’t charge our devices in a mobile way? Outlets in automobiles don’t count. We’re still confined to our cars during the charging process of our devices on the road. What happens after you hop onto the sidewalk and your phone doesn’t have enough juice to handle a day in the city? Well don’t fret, my friends, because we may be in luck.
The concept of using naturally re-occurring sources of energy is nothing new. Windmills date back to the first century AD, and hydro-power even further – going all the way back to the ancient Mesopotamian empire around 4000 BC in which they used gravity and flowing water to rotate bladed turbines.
Nowadays though, the renewable energy industry is flowing with innovation and new, effective implementations and ideas for sustainability – one of the newest of which is renewable energy clothing or apparel that generates small amounts of electrical power.
No, I’m not talking about strapping a wind turbine to your back, and I’m definitely not suggesting you put a portable hydrogen generator into a backpack and lug that around all day, no.
The photographers over at Pauline van Dongen have showcased a new line of – get this – solar powered clothing.
That’s right! Solar fibers manufactured by Dutch start-up company “Solar Fiber” are being used in clothing prototypes for the purpose of generating enough electricity to charge your phone on the go. While such technology is still in very early phases of design, this opens the gates for innovators in the renewable energy industry to optimize and possibly even come up with better alternatives.
While the concept is truly amazing in theory, the technology hasn’t quite caught up with the energy requirements needed to actually charge mobile devices in today’s world. On top of that, one could make an educated guess that such apparel would only be financially available to people with fat wads of cash to spend on solar-powered clothing.
Personally I think some of these pieces of clothing look like suits of armor you’d see a Night’s Watchman wearing from Game of Thrones – not particularly my personal taste for fashion but hey, it might work next time you decide you want to charge your cell phone during your visit to King Richard’s Faire.

Profitable, Clean Tech Solution to Grid Congestion in China

Boston,MA United States
Angstrom Advanced Inc has paid a lot of attention to what is going on in China, especially the renewable energy section. The leading magazine "Energy Digital" recently published an article from Verde about this market opportunity:
"As China's economy rapidly grows, the energy sector faces two major challenges: an imbalance of supply and demand and a lack of distribution and transmission infrastructure.
As by far the largest wind power market in the world (with 63 GW installed capacity), China gets more than 30% of its wind market's revenue from federal subsidies—an exceptional amount of support from the government that has adversely caused a massive oversupply issue. In 2011, abandoned wind power amounted to over 10 billion KWh, exceeding 50 percent of the industry's profit. Much of that energy was wasted, mostly positioned near farms lacking sufficient distribution/transmission infrastructure capable of moving excess energy to areas of higher demand. "
