摘要： A method and controller compensates control variables of a continuous process prior to the control variables being input to the controller/control matrix to at least partially mask the effect of a selected disturbance or a manipulated variable on that controlled variable to the controller. The controlled variable(s) has been chosen to be an inference of a desired underlying or related variable which is not directly measurable. The selected disturbance to be masked is one which does affect the (measured) controlled variable, but not the underlying desired variable. By at least partially masking the effect to all intents and purposes the controller is unaware of the effect of the selected disturbance on the controlled variable and therefore, for a fully masked disturbance, does not make any adjustment to a manipulated variable associated with the selected disturbance which would unnecessarily alter the underlying desired variable. In the event of a partially masked disturbance there will be some modification of the manipulated variable in comparison to that which would occur in the absence of the method.

摘要： A method for operating a main cryogenic heat exchanger for use in a natural gas liquefaction process, involves monitoring or predicting variations in the flow rate of a feed gas stream provided to the main cryogenic heat exchanger. When a variation of the flow rate exceeding a predetermined threshold value is monitored or predicted, a control scheme is started to control one or more compressor recycle valves in response to the monitored or predicted variation of the flow rate to recycle part of a compressed mixed refrigerant stream in a refrigerant loop.

摘要： The present invention relates to the control systems of the compression refrigerating machines, namely, to the methods of control of the natural gas liquefaction process to produce liquefied natural gas (LNG), and can be used for liquefaction and cooling of natural gas on the most major technological lines and LNG production plants, working on the mixed refrigerant (MR). The method of control of the natural gas liquefaction process, on the mixed refrigerant-operating LNG production plant comprises a periodic measuring of the current parameters of the said process, and controlling composition of the mixed refrigerant entering the main cryogenic heat exchanger, in order to achieve the optimal process parameters. Carnot factor is used as an optimality criterion for parameters of the process. The mixed refrigerant composition is controlled by direct calculation on the basis of the current process parameters and equation of state (for example, Peng-Robinson equation of state) of the substance amount of the mixed refrigerant components required to obtain in the main cryogenic heat exchanger the temperature profile corresponding to the optimal process parameters, and to introduce the said components into the main cryogenic heat exchanger. The invention improves efficiency of the natural gas liquefaction process and, as a result, minimizes specific compressor power required for LNG production.

摘要： Systems and methods are provided for adjusting a composition, pressure, and/or flow rate of a mixed refrigerant (MR) fluid in a liquefaction system to provide refrigeration to natural gas (NG) feedstock to produce liquefied natural gas (LNG). The MR fluid that is in circulation within a liquefaction system can include heavy components and light components. During LNG production, heavy components and/or light components of the MR fluid can be selectively removed from, and reintroduce into the MR fluid, thereby altering the composition of the remaining MR fluid in circulation. Adjusting the composition of the MR fluid in circulation within a liquefaction system can allow the system to be optimized to maximize efficiency, LNG production, and or profitability while the system is in operation.

摘要： A compressed vaporous discharge stream is de-superheated in a de-superheater system. The de-superheater system comprises a de-superheater heat exchanger configured to bring at least a portion of the compressed vaporous discharge stream in indirect heat exchanging contact with an ambient stream. A de-superheater bypass line comprising an temperature-controlled valve is configured to selectively bypass the de-superheater heat exchanger. A combiner is configured downstream of the de-superheater heat exchanger for rejoining the bypass portion with the portion of the compressed vaporous discharge stream that has passed through the de-superheater heat exchanger. A mixer is configured downstream of said combiner, to receive and mix the rejoined stream, and discharge the rejoined stream into a de-superheater discharge conduit as a de-superheated stream.
