Angstrom Advanced HGH-300 and HGH-500 Hydrogen Generator

Introduction

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.

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.

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

sIntroduction

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. Specification

H2 capacity	10-5000 Nm3/h
Dew Point	≤-60C
H2 purity %	>98-99.999%
Work pressure	0.2-4.0MPa

PSA Process Overview

Pressure-Swing Adsorption or PSA is a technical process widely used these days in gas production. 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 adsorbs 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.

Hydrogen Generator by Ammonia Decomposition with Purifying System is very low cost; it has long service life, simple operation, compact structure, small coverage, and is very simple to install. Liquid ammonia is used as source for hydrogen generator. The liquid ammonia is vaporized and is heated by decomposition with catalyst into mixed gas containing 75% hydrogen and 25% nitrogen.
