Introduction:
Angstrom Advanced Hydrogen Generating Plant by Ammonia Decomposition offers a variety of benefits. The system is low cost, has a long service life, simple operation, compact structure, small coverage and simple installation. The system vaporizes liquid ammonia, and heats it with a catalyst until decomposition occurs, creating a mixture of gas consisting of 75% hydrogen and 25% nitrogen. Based on the principle that the molecular sieve adsorbs ammonia and water at different temperatures, high purity gas is produced by heat regenerating through the mixture working at normal temperature. Angstrom Advanced services for hydrogen plant projects typically include conceptual design, detailed engineering, procurement, fabrication, construction, start-up and operational training. Our goal is to provide our customers with the best products with highest standard of service at cost efficient pricing.

Introduction
Hydrogen generation by methanol decomposition was developed in the last two decades. This technology by Angstrom Advanced features low cost, simple user friendly operation and very easy maintenance. The methanol and water is mixed in specified ratio and pressurized. This mixture passes through evaporator, metering pump and then to super heater. The hot gas is then fed into a reactor. The reaction of methanol reforming and the shift reaction, takes place in the catalytic reactor of fixed beds simultaneously to form H2 and CO2 finally. The mixed gas after reaction is passed though the heat exchanger to have the heat exchanged with feed gas in order to recover part of heat and then fed further into the gas-liquid separation buffer to separate the unreacted methanol and water, prior to passing to the condenser and cooling gas dryer for condensation in order to ensure the methanol in the reforming gas to meet the specified quality. The liquid from condensation and separation is the mixture of methanol and water, which are returned back to the feedstock tank for reuse. The reformed gas enters a set of PSA systems, which separates all impurities through the adsorption and separation in one time. The hydrogen purification through PSA is adopted in the manner of 4-1-2/P and desorption at the atmospheric pressure (4 absorbers, one absorber is in adsorption, 2 times of pressure equalization). Each adsorber in a cycle undergoes adsorption (A); equalized pressure-drop for the first time (E1D); equalized pressure-drop for the second time (E2D); cis-exhale (PP), inverse purge (D); flushing (P); equalized pressure increase for the second time (E2R); equalized pressure increase for the first time (E1R) and the final pressurisation (FR). The four adsorbers shift regularly, alternating between adsorption and regeneration, according to the arranged program in a closed loop. In this way raw gas feeds and hydrogen withdraws continuously. There are a small amount of carbon monoxide and about 35%(v/v) hydrogen in the desorbed off gas. If it is recovered and used as fuel, it brings the benefit of saving energy and minimizing the pollution.

Prior to pressurization, desulfurization, and mixing with aqueous vapor, natural gas is passed through a special reformer which is packed with a catalyst for cracking and reforming the effluent mixture of hydrogen, carbon dioxide and carbon monoxide. After part of the heat is recovered, hydrogen will be obtained by removing excess carbon monoxide from the reformed effluent. The shift gas is then purified further through pressure swing adsorption (PSA), to obtain pure hydrogen.

Introduction: |
||||||||||||
Pressure Swing Adsorption (PSA) by Angstrom Advanced is used to separate hydrogen gas from other gases by feeding the gas under a certain pressure. This separation process occurs in an adsorption tower and is advantageous in its low cost, low capacity, minimal maintenance requirements and user-friendly interface. The H2 Purifying System removes oxygen from hydrogen via a catalyst to obtain high purity H2 after adsorption and drying through the dust filter. The system can remove oxygen down to levels of 1ppm. Through one step of purification, the purity of the hydrogen generated can reach between 99.999~99.9999% and the dew point can be lower than -70°C; Through a second purification step, impurities can be lowered down to less than 0.1ppm and dew point can be lowered to -90°C.Our instruments and plants have been delivered to many renowned organizations.
