摘要： An embodiment represents composition of molecules in a feedstock as a combination of individual molecule representations and molecular attribute representations. A representation of chemistry of a chemical reaction of the feedstock in a chemical reactor is then formulated based on the representations. Then, a simulation of the chemical reaction of the feedstock in the reactor is performed using the representations to determine composition of products of the reaction. A first subset of the products are represented as individual molecule represented products, and a second subset of the products are represented as attribute represented products. In turn, the attribute represented products of the second subset are sampled to determine individual molecule representations of the attribute represented products. As a consequence of the sampling, individual molecule representations of the first and second subsets of the products of the chemical reaction of the feedstock in the chemical reactor result.

摘要： A method, apparatus, and computer program product for increasing closed-loop stability in a MPC controller controlling a process where there are significant uncertainties in the model used by the controller. This invention focuses on the improvement of the robustness of the steady-state target calculation. This is achieved through the use of a user defined robustness factor, which is then used to calculate an economic objective function giveaway tolerance and controlled variable constraint violation tolerance. The calculation engine uses these tolerances to find a solution that minimize the target changes between control cycles and prevent weak direction moves caused by near collinearity in the model. If the controller continues to exhibit large variations in the process, it can slow down the manipulated variable movement to stabilize the process.

The subject facility design includes design alternatives, and a processor routine coupled to the input module and responsive to the user specification by forming an input data set to a rigorous simulation modeler to model the subject facility design. The rigorous simulation modeler requires input beyond the limited data. The processor routine enables execution of the simulation modeler. The computer modeling apparatus further includes an interface member that enables the production of a rigorous simulation model of the subject facility design from the simulation modeler. The subject facility is one of an oil processing facility, a gas processing facility, an oil and gas separation facility, or a chemical processing facility.

摘要： A method of designing or optimizing a column for a separation process includes the computer implemented steps of, in a digital processor, providing vapor- side and liquid-side mass transfer coefficient expressions and a mass transfer area expression relevant for a subject column, the vapor-side and liquid-side mass transfer coefficient expressions and the mass transfer area expression having been derived from defining a column average height equivalent to a theoretical plate 〈HETP〉) as a mathematical relationship in which 〈HETP〉 is proportional to a vapor flow rate, is inversely proportional to effective packing area participating in mass transfer, has a first correction factor with respect to liquid-side mass transfer, and has a second correction factor with respect to vapor-side mass transfer. The expressions are further derived from reducing error of curve fitting 〈HETP〉 empirical data of various columns by using the defined 〈HETP〉 to obtain expressions for the vapor-side and liquid-side mass transfer coefficients and mass transfer area. The method also includes using the provided expressions to determine column height and column width configurations of the subject column, and outputting the determined column height and column width configurations of the subject column.

摘要： A method and system for estimating wax or hydrate deposits is desirable for the oil industry and important for assuring flow conditions and production, avoiding downtime, and reducing or preventing costly interventions. The method and system disclosed herein use artificial intelligence and machine learning techniques combined with oil well historical operational sensor data and historical operational event records (such as diesel hot flush, slick line, coil tubing, etc.) to build an oil well model. The method and system enable oil well practitioners to test and validate the built model and deploy the model online to estimate and/or detect wax or hydrate deposition status. By using one or more such models in operating an oil well, users can monitor and/or detect the status of wax of hydrate deposits in an oil well and can optimize production, maintenance, and planning for oil wells.
