    摘要： The present invention relates to a method of controlling prepurifier cycle time by monitoring ambient CO2 level in order to prevent CO2 breakthrough occurrences caused by extreme instantaneous variations in ambient CO2 level. Rather than operating solely by prepurifier design bed capacity, the method of the invention continuously updates bed capacity for the contaminants using the feed temperature, pressure and contaminants composition, calculating the total amount of contaminants that were fed to the prepurifier during the feed step and estimates the perturbation front velocity, i.e., the velocity at which the contaminants front coming from an extreme instantaneous variations of ambient level is going to propagate inside the adsorbents bed. Estimating the perturbation front velocity allows for a more precise estimate of the maximum time remaining for the feed step before starting to experience CO2 breakthrough. This eliminates the need to switch the online bed unnecessarily early and risking shorter regeneration for the offline bed.

    摘要： The present invention relates generally to radial flow vessels and processes to achieve even fluid flow distribution through the bed during purification, separation or reaction processes. The radial bed vessel is designed such that the ratio of the cross-sectional flow areas of the flow channels is in proportion to the ratio of the mass flow rates of the process gas with the proportionality constant between 0.7 and 1.4. In addition, the channels each have a cross-sectional flow areas such that the pressure change within each channel is less than or equal to 10% of the pressure drop across the bed of active material under the process operating conditions for the particular gas employed.

    摘要： A system and method of regenerating a pre-purification vessel is provided that is particularly suitable for pre-purification of a feed air stream in cryogenic air separation unit that uses an oxygen-enriched purge gas stream for regeneration of the pre-purification unit. The disclosed pre-purification systems and methods are configured to remove substantially all of the water, carbon dioxide and other impurities from a feed air stream, optionally including hydrogen and carbon monoxide impurities. The method of regenerating a pre-purification vessel preferably involves regenerating the pre-purification vessel with an oxygen-enriched purge gas after depressurization of the vessel and thereafter partially repressurizing the pre-purification vessel with an auxiliary purge gas thereby diluting the oxygen concentration of the gases contained in the pre-purification vessel and optionally depressurizing the partially repressurized vessel.

    摘要： A system and method of pre-purification of a feed gas stream is provided that is particularly suitable for pre-purification of a feed air stream in cryogenic air separation unit. The disclosed pre-purification systems and methods are configured to remove substantially all of the hydrogen, carbon monoxide, water, and carbon dioxide impurities from a feed air stream and is particularly suitable for use in a high purity or ultra-high purity nitrogen plant. The pre-purification systems and methods preferably employ two or more separate layers of hopcalite catalyst with the successive layers of the hopcalite separated by a zeolite adsorbent layer that removes water and carbon dioxide produced in the hopcalite layers. Alternatively, the pre-purification systems and methods employ a hopcalite catalyst layer and a noble metal catalyst layer separated by a zeolite adsorbent layer that removes water and carbon dioxide produced in the hopcalite layer.

    摘要： A modular and compact adsorbent bed structure is disclosed for use in an adsorption-based gas separation plant. The conventional adsorbent bed in a gas separation plant is replaced with a plurality of modular adsorbent bed units connected to make the adsorbent bed structure. Modular adsorbent bed units of this invention provide higher capacity of product per unit volume of adsorbent material (i.e., increased adsorbent utilization) as compared to that obtained from conventional adsorbent beds. The modular design requires lower fabrication costs; is easier to transport; has less maintenance and repair requirements; and is easier to load with adsorbent material.

    摘要： The present invention generally relates to the attenuation of vacuum blower noise using a silencer. More particularly, the present invention relates to a low-cost, reliable and efficient silencer for reducing noise levels in adsorption-based gas separation plants from the discharge of the vacuum blower or from the feed blower inlet, to about the 90 dBA level or less, at the silencer opening to the atmosphere. The silencer includes at least one reactive chamber(s) to attenuate low frequency pulsations and at least one absorptive chamber(s) to attenuate noise at medium to high frequency noise.
