  • Patent number: 10317136
    Abstract: An onsite purification plant/system to delivery high and ultra high purity product, such as, process chemicals, industrial and specialty gases to manufacturing processes within the onsite plant turndown ratio from 0% to 100% while preserving the predetermined purity of the supplied substances within a predefined specification range is provided. Preserving liquid/vapor ratio in at least one of the purification means/units ensuring that product purity range stays unchanged is achieved by redirecting the product back into the onsite purification plant/system.

  • Patent number: 7919057
    Abstract: A process and apparatus for producing a hydrogen-containing gas in a reformer where a furnace, which is independent of the reformer, heats the effluent from a prereformer prior to reacting the prereformer effluent in the reformer. The prereformer effluent may be heated in a heat exchange tube in the furnace where the heat exchange tube is positioned in the furnace to preclude direct radiation from any flames in the furnace thereby preventing local overheating of the heat exchange tube and preventing carbon formation in the heat exchange tube. Fuel and oxidant gas may be introduced into the furnace with significant excess oxidant gas, having a stoichiometric ratio of 1.8 to 2.8 for controlling the temperature of the heat exchange tube.
