Filed: 1991-08-01
Abstract: Extn. of He from a feed gas (I) contg. moderate amts. of He and traces of N2 (sic; H2 elsewhere) involves (a) sepg. He from (I) by pressure swing adsorption (PSA); and (b) sepg. the H2 impurity in a catalytic bed. Pref. (I) contains (6-40%), N2, CH4, water vapour, Ar, higher hydrocarbons and H2 (under 1000 ppm). If (I) contains considerable amts. of N2, less than 5% CH4 and less than 1000 ppm CO2, stage (b) is carried out before (a). Stage (a) is carried out at an adsorption pressure of 25-150 psia and ambient temp.; and a sec. prod. regeneration stream, is used to keep He losses low and ensure the purity of the He prod. Ni catalyst is used in (b). This is regenerated periodically by passing a regenerative mixt. of an inert gas (Ar, N2 and/or He) and a regulated amt. of an oxidant (max. ca. 5000 vpm O2) over the spent catalyst, contg. adsorbed H2, under ambient conditions and continuing until the catalyst is free from chemisorbed H2; removing the water formed by passing an inert gas stream heating to ca. 200 deg.C; and cooling to ambient temp. with an inert gas. ADVANTAGE - Purified He contains less than 1 vpm H2. Technique is effective and economical and avoids the use of cryogenic temps. and thermal regeneration of the catalyst.

In this case, during the desorption phase, depressurisation initially occurs down to the desorption pressure, before the adsorbent to be desorbed is flushed with the product gas component from the buffer vessel in countercurrent to the adsorption direction. After the desorption phase, the desorbed adsorbent is prepressurised in countercurrent to the adsorption direction with the product gas component from the buffer vessel and at the end of the pressure buildup phase, pressure equilibration between the adsorber in the pressure buildup phase and an adsorber which has completed the adsorption phase is carried out via the adsorber inlet sides.

Title: Method for charging and discharging a heat store (reservoir) with a simultaneous pressure-maintaining function in the heating grid
Inventor: ECKERT ADOLF
IPC: F24D11/00
Filed: 1993-05-08
Abstract: The invention relates to a method for charging and discharging a heat store without applying special charging and discharging pumps.
