摘要： A process of continuously controlling at least one characteristic of a simulated moving adsorbent bed separation process has been developed. The characteristics controlled may be the purity or the recovery of the component of interest. The process involves measuring the concentration of the components in the pumparound or pusharound stream, calculating the value of the characteristic, and making required adjustments to operating variables according to an algorithm which relates changes in the value of the characteristic to the changes in the concentrations of the components resulting from changes in the operating variables. The process is unique in that the necessary quantity of data to control the separation is rapidly generated, thereby providing increased efficiency, precision and accuracy.

摘要： A process for sensing hydrogen in a refinery process stream or a chemical process stream has been developed. The process comprises flowing at least a portion of the refinery process stream or the chemical process stream through a conduit which is part of a main support and through a series of flow components which are attached to the main support and in fluid communication with the conduit. The flow components comprise, a needle valve, a pressure indicator, a catalytic alloy hydrogen sensor, and a back pressure regulator. The catalytic alloy hydrogen sensor may be a palladium-nickel catalytic alloy hydrogen sensor. The process continues with generating a signal indicating the amount of hydrogen in the stream using the catalytic alloy hydrogen sensor and communicating the signal to a display device or a computer processor. The process may further include adjusting an operating parameter based upon the signal indicating the amount of hydrogen in the stream, or based upon a calculated mole percent hydrogen. The process of the invention may be used for controlling a refinery or chemical process.

The characteristics controlled may be the purity or the recovery of the para-xylene. The process involves measuring the concentrations of the para-xylene, meta-xylene, ortho-xylene, and ethylbenzene in the pumparound or pusharound stream, calculating the value of the characteristic, and making required adjustments to operating variables according to an algorithm which relates changes in the value of the characteristic to the changes in the concentrations of the components resulting from changes in the operating variables.
