Angstrom Advanced Hydrogen Plant Electrolyser

Oxygen and electrolyte from anode side are pumped into oxygen separator, there oxygen separates with electrolyte under the action of gravity, then oxygen passes through oxygen cooler, be cooled to the temperature of 30~425℃, where after it passes through oxygen demister to remove liquid water from gas. The electrolyte at the bottom of oxygen separator is pumped back to oxygen side cell of the electrolyser after filtering and cooling, oxygen side circulation is finished.

According to the capacity and work pressure of hydrogen generator, the handling capacity of hydrogen purifier is determined. In order to guarantee the quality of hydrogen after purification, we use purified hydrogen as regeneration gas.

The total system by Angstrom Advanced includes hydrogen generator, hydrogen purifier, electrical and control unit as well as a hydrogen buffer tank and a storage container.In this unit, water is decomposed into hydrogen and oxygen through electrolysis, the equation is 2H2O==2 H2+O2. There is a hydrogen buffer tank between hydrogen generator and hydrogen purification equipment; it is used to remove dissociative water from hydrogen and to keep the pressure of hydrogen purification unit stable. Hydrogen flows into purifier though this buffer. The action of purification equipment is to purify the hydrogen generated by hydrogen generator. The oxygen is removed though chemical reaction under the action of catalyst, and water is removed by the way of adsorption.

Hydrogen, oxygen and electrolyte are sent to hydrogen and oxygen separators installed in auxiliary equipment frame, there hydrogen and oxygen are separated with electrolyte under the action of gravity, hydrogen and oxygen gases pass through hydrogen and oxygen coolers separately and are cooled to the temperature of 30~425℃, then pass through hydrogen and oxygen demisters to remove liquefied water from gases, then hydrogen and oxygen are supplied out. The pressure of the system is raised to and maintained at the set pressure by means of regulation valve. The electrolyte at the bottom of hydrogen and oxygen separators is pumped back to electrolyser after filtering and cooling, then, one circle is finished.

The hydrogen from water electrolysis has the advantages of high purity and simple composition, normally only has the impurities like oxygen and water, it is easy to purify it to much higher purity used in electronic industry.

Nitrogen Generator Pressure Swing Adsorption

The technology of air-to-nitrogen production with the use of adsorption processes in nitrogen generators is well studied and widely applied at industrial facilities for the recovery of high-purity nitrogen. The operating principle of a nitrogen generator utilizing the adsorption technology is based on the dependence of the adsorption rates featured by various gas mixture components upon pressure and temperature factors. Among nitrogen adsorption plants of various types, Pressure swing adsorption (PSA) plants have found the broadest application world-wide. The system’s design is based on the regulation of gas adsorption and adsorbent regeneration by means of changing pressures in two adsorber–adsorbent-containing vessels. This process requires constant temperature, close to ambient. With this process, nitrogen is produced by the plant at the above-atmospheric pressure, while the adsorbent regeneration is accomplished at below-atmospheric pressure. The swing adsorption process in each of the two adsorbers consists of two stages running for a few minutes. At the adsorption stage the adsorbent serves to adsorb predominantly one of the gas mixture components with the recovery of product nitrogen. At the regeneration stage the adsorbed component is released from the adsorbent and is vented in the atmosphere. The process is then multiply repeated.

Angstrom Advanced Hydrogen Generator HGH 300/500

Angstrom Advanced HGH-300/500 Portable Hydrogen Generator

Introduction

Angstrom Advanced HGH-300 and HGH-500 high purity hydrogen generators are based on the technology of astronautic fuel cells, in which hydrogen is produced by the electrolysis of water, and the produced oxygen is released into the atmosphere. The generator consists of electrolyzing/separating pool, power supply, pressure control, desiccation& purification, flow display etc. The core part — electrolyzing & separating pool, uses a tube shaped positive pole and a plate shaped negative pole. Both poles are made of stainless steel. The electrolyzing & separating pools store electrolytes, produce hydrogen as well as release hydrogen at the same time. The HGH series hydrogen generators have the advantages of large electrolyzing area, low temperature of the pool, better performance, high production and high purity of hydrogen. The instrument has been specially designed to prevent liquid from back-flowing. These generators have state of the art technology, stability and functionality for scientific instruments, industry and solar and wind energy.

Features

It is very easy to operate — all you need is to turn on the switch. The pressure of released hydrogen is steady. The flow rate is digitally displayed on the LED display. The only material that the instruments consume is distilled water. The liquid storage, hydrogen electrolyzing and desorbing are integrated together in the instrument The generator features large electrolyzing area, low pool temperature, long service life combined with high production and high purity of hydrogen. The instrument has specially designed components that prevent liquid from back-flowing. As a result, there is no need to change the discolored silica gel frequently. The adoption of the advanced power switches improves the electrolytic efficiency. The generator is a great substitute of high-pressure steel bottles used in the laboratory application.

Angstrom Advanced Developing Powerful Communities: Small, community wind & storage projects – Boston, MA United States

Deriving power from the wind is nothing new. Reports have windmills dating back to 200 B.C. What began as small-scale attempts to harness energy, have developed into multi-megawatt producing machines today. As technologies have advanced, approaches to generating power from the wind are more efficient than ever before. We’re collecting clean, renewable energy from wind comprehensively in larger and larger scales. But what does that mean for those smaller wind energy systems…or should we simply relegate them to the past? Angstrom Advanced delivers a reputable and highly efficient world accepted renewable energy product line.

Larger turbines might have replaced smaller ones in many cases, however, not everywhere. The global market for small and medium wind turbines (SMWT) is actually forecast to double by 2015, especially in developing markets, reaching US$634 million.
