摘要： A method and related non-linear level controller (NLLC) for controlling surge capacity in a processing system including at least one vessel receiving an inlet flow of a fluid including a liquid subject to variation and supplying an outlet flow to at least one downstream unit includes the step of computing a first parameter relating to a difference between a current inventory in the vessel and a prevailing inventory limit for the vessel and a second parameter relating to a difference between the current inventory and an inventory set point. An unforced time to reduce the first parameter by a first percentage (T*) is compared to a first time T1. The inlet flow or outlet flow is then controlled based on the first parameter if T*≦T1 and based on the second parameter if T*>T1.

摘要： A method includes obtaining a model associated with production of natural gas from a well, where the well has a choke valve that controls flow of material including natural gas from the well. The method also includes identifying, using the model, a solution that increases an amount of natural gas obtained from the well over a specified time horizon. In addition, the method includes adjusting operation of the choke valve based on the identified solution. The model could be generated using geological data associated with the well and/or historical data associated with natural gas production from the well. A natural gas reservoir can be modeled as a continuous stirred bed with a rock or shale void fraction using mass or volumetric unit balances. Gas content versus pressure for the well can be plotted, and Langmuir adsorption parameters for the well can be identified using the plotted gas content versus pressure.

摘要： A system includes a controller and an apparatus that includes a housing having a volume and an inlet. The inlet can receive a fluid that includes a gas and a liquid. The apparatus also includes a baffle that partitions the volume into a first portion and a second portion. The baffle extends from a base of the housing. The first portion can receive the liquid and separate the liquid into a first part and a second part. The second portion can receive the second part of the liquid from the first portion. The controller regulates an amount of the second part of the liquid in the second portion such that a level of the second part of the liquid is higher than a height that the baffle extends from the base of the housing, thus enabling the use of the extra surge capacity in the vessel.
