摘要： A powdery material mixing and feeding system (B) is configured to feed a machine (A) configured to execute a post process with mixed powdery materials obtained by mixing a first powdery material and a second powdery material discharged from powdery material feeding devices (B1, B2) at a required ratio, wherein when a flow rate of the first powdery material discharged from the first powdery material feeding device (B1) departs from a target value by a predetermined amount or more, a controller (B05) increases or decreases the flow rate of the second powdery material discharged from the second powdery material feeding device (B2) such that the ratio of the first powdery material to the second powdery material contained in the mixed powdery materials is kept within a desired range.

摘要： The temporary relaxation of constraints permits the efficient and cost-effective operation of certain process models. Ramp imbalances are controlled using soft-landing constraints. Such soft-landing constraints permit a smooth return to a ramp limit which permits continued operation of a system, such as a petrochemical system that includes several inflows and outflows, as opposed to a forced shut-down of the system. A ramp imbalance may be controlled by determining imbalance ramp rates and imbalance set-point ramp rates and using those constraints to resolve the dynamic control problem of a process model.

摘要： A tank overflow protection system and method for measuring process temperature and pressure utilizing one or more piezoresistive pressure transmitters. The piezoresistive pressure transmitter includes a differential pressure sensor and a temperature sensor. Data from the piezoresistive pressure transmitters can be digitally communicated via a cable. The pressure transmitters convert signals indicative of temperature and pressure to a digital value and transmit the signals to a main processor printed wire assembly for final compensation, diagnostics, and transmission to a distributed control system. A differential pressure can be calculated by subtracting two digital pressure measurement values. The temperature measurement can be employed to calculate any changes in density for a user-defined reference value.

摘要： The invention relates to an arrangement and to a process for providing a liquid mixture, which is preferably variable with time, of at least two liquids, comprising at least two feed lines (1, 2) each for feeding in one of the liquids, each feed line (1, 2) being provided with at least one regulating valve (4, 5) for adjusting the flow of the particular liquid fed in, and comprising a pump (11), the feed lines being combined to a single pump feed line (12) and the pump feed line (12) being conducted to a suction-side connection of the pump (11). According to the invention, for the combination of the feed lines (1, 2) to the pump line (12), a mixing vessel (3) is provided, to which the two feed lines (1, 2) are fed and from which the pump feed line (12) leads away. In this way, it is possible in a reliable manner to achieve, for example, a chromatographic separation in a low-pressure gradient method.

摘要： A method of providing a continuous, sequential, and cyclic, if desired, liquid feed to a processor from a plurality of containers, which comprises feeding the liquid from a first of the containers through a first conduit to a reservoir having a float valve, to keep the level of the liquid in the reservoir high enough to maintain the float valve in an upper floating position that closes the float valve. The first conduit is uncontrolled by the float valve. The float valve controls a second conduit which connects with a second container. As liquid is withdrawn from the reservoir for processing, liquid from the first conduit and container replenishes the reservoir until it is exhausted. Then, the liquid level drops, and the float valve opens the second conduit for replenishing the reservoir with liquid from the second container. A crossover valve may be used so that the float valve controls flow from either container connected to the second conduit.
