摘要： A method is disclosed for controlling a simulated moving bed system of a type including at least four series-arranged beds each packed with a solid adsorbent, with the downstream end of each bed and the upstream end of the next succeeding bed being connected by conduits to form an endless loop, and in which a fluid is caused to circulate through the beds in one direction, a feed stock and a desorbent are introduced into the system while a raffinate and a sorbate are withdrawn from the system, and the positions of introduction and withdrawal of the four kinds of fluid are periodically shifted in the direction of the circulating fluid flow. In accordance with the invention, two or more circulating pumps, provided with variable speed controllers and pressure detectors for detecting the suction pressure of each of the circulating pumps, are disposed between two beds. The flow rates of three of the four fluids introduced into or withdrawn from the system are adjusted to predetermined values, and the flow rate of the other fluid is controlled in such a manner that the suction pressure of one of the circulating pumps or the average of the suction pressures of two or more of the circulating pumps is held constant, and a rotational speed of each of the circulating pumps is controlled independently so as to control the flow rate of the circulating fluid and to maintain the suction pressure of each circulating pump at a low level.

摘要： A separation device designed to effect substantially continuous separation and/or fractionation operations as in, for example, ion exchange or other solid-fluid contacting systems. Also disclosed and claimed is a method for effecting such continuous treatment of plural fluid streams. The device is characterized by its construction to permit treatment of plural streams simultaneously and continuously. Fixed inlet and outlet nipples are provided for introducing and removing the fluid streams, and the inlet and outlet nipples are operatively interconnected by a rotating member which is internally divided into a plurality of working sections. By virtue of the rotatable construction of that member and its plural working sections, discrete fluid streams may be treated separately, yet simultaneously. Furthermore, the device of this invention is such that fluid flow in either of two directions may take place through each of the working sections dependent only upon predetermined process parameters.

摘要： A system and process for determining the concentration of nonmethane organic chemicals in a gaseous sample includes a separation system to receive the gaseous sample. In the separation system nonmethane organic chemicals including ethylene and ethane are reversibly retained on a packing material while methane and inert gases pass through the separation system and are vented. Thereafter a carrier gas is directed through the separation system, the nonmethane organic chemicals are released into the carrier gas, and the carrier gas containing the organic chemicals is conveyed to an analyzer for analysis of the organic chemicals.

摘要： An analysis of the concentration of the individual components of a sample is obtained using a chromatographic analyzer where the concentrations of the individual components or the sensitivity of the detector to the individual components vary over a wide range. The sample is injected into a first chromatographic column and trace components of interest are eluted to a detector for measurement. The major components are backflushed, diluted, provided to a second chromatographic column and then eluted to a detector for measurement. The dilution of the major components ensures the linearity of the detector response. Analysis of both the trace components and major components is thus provided.

摘要： An apparatus for sampling an atmosphere for the presence of a constituent in which a flow of the atmosphere is first drawn through a trap capable of releasably absorbing the constituent and the trap is then passed through a carrier gas stream which removes and conveys the constituent into a detector. The trap can comprise a rotatable disc of wire mesh which cuts continuously across a flow of the atmosphere and a carrier gas flow. The volume flow rate of the atmosphere is greater than that of the carrier gas so giving a large concentration gain of the constituent in the carrier flow. The apparatus can be used for detecting the presence in the atmosphere of vapors emanating from explosives and for this purpose the carrier gas flow can be directed into an electron capture detector.
