摘要： A system of interlocks for controlling flow of low temperature process streams in a manufacturing process through a cold box to equipment or piping not specified for such temperatures by opening and closing valves and starting and stopping pumps. At least one interlock affects streams heated in the cold box. At least one interlock affects the streams cooled in the cold box. The interlocks are activated by temperatures of process lines to prevent exposure of equipment and piping to low temperatures while preventing the shutdown of the cold box. An override controller including a predictive failure capability is also provided.

摘要： The process can include transferring heat from a light product in a first heat exchange stage to produce a cooled product and a first medium pressure steam and separating a steam cracker quench oil therefrom. Heat can be transferred from the steam cracker quench oil in a second heat exchange stage to produce a first cooled quench oil and a second medium pressure steam. Heat can be transferred from at least a portion of the first cooled quench oil in a third heat exchange stage to produce a second cooled quench oil and low pressure steam. A total heat duty generated in the first heat exchange stage, the second heat exchange stage, and the third heat exchange stage can be equal to QT1 and a heat duty generated in the first heat exchange stage and the second heat exchange stage can be ≥0.5QT1 joules/sec.

摘要： An apparatus includes at least one processor configured to obtain inline measurements of one or more properties of crude oil, translate the measurements into a set of process and control parameters, and apply the process and control parameters to process equipment. The process and control parameters configure the process equipment to process the crude oil having the one or more properties. The one or more properties of the crude oil may include at least one of: density, specific gravity, viscosity, carbon residue, and sulfur content of the crude oil. The process and control parameters could be applied to one or more controllers associated with a blending unit in a refinery or to one or more controllers associated with a crude oil distillation column in the refinery.

摘要： Turbine fuel provided for large-scale land based turbines used by utilities for producing electricity and desalinated water, and for large mobile engines and turbines in marine and remote applications where only liquid fuels are available. Use results in less corrosion, ash formation and emissions (NOx, SOx, CO2 and noxious metals) than firing contaminated heavy crude, refinery residual oils or high sulfur fuel oils. Manufacture is by decontaminating crude oils, non-conventional crudes, and other highly contaminated feeds. Each fuel is produced as a single product of unit operations, not ex-plant blend of various refinery products, yet using an apparatus configuration less complex than conventional crude oil refining. These fuels can be fired by advanced high efficiency turbines of combined cycle power plants having hot flow paths and heat recovery steam generation systems susceptible to corrosion, which systems cannot otherwise risk contaminated heavy crudes or refinery residual oils feeds.

摘要： Methods and systems for predicting crude oil blend compatibility and optimizing blends for increasing heavy crude oil processing are described. The method includes receiving ratios of physical parameters of crude oils for optimization of crude oil blend. The physical parameter ratios are based on Kinematic Viscosity (V), Sulphur (S), Carbon Residue (C), and American Petroleum Institute (API) gravity. The crude oil blend compatibility (K model) is determined and generated using the physical parameter ratios. The K model is developed by coefficients obtained by regression analysis between the ratios of physical parameters of known crude oils and composite compatibility measure determined from multiple compatibility test results of the known crude oils. The predicted crude oil blend compatibility can be used for optimizing heavy crude oil processing.

摘要： A process for separating naphtha feed stream and recovering heat from at least one stream from a column by heating other columns. Preferably, both an overhead stream and a bottom stream from a first column heat a second column and a third column. The pressure of the overhead stream is increased, resulting in an increased temperature of the overhead and bottoms streams. The overhead stream can be split into portions to heat other columns.

摘要： The present invention relates to a method of refining crude tall oil. According to the method, the crude tall oil is fed into a column distiller, where it is separated into desired fractions. The conditions of the column distiller are adjusted on the basis of the composition of the feed and the product flow. According to the present invention, the densities of the crude tall oil fed into the column distiller and of at least one product flow are measured accurately as a function of the temperature. The density values are compared with correlation coefficients derived from the chemical compositions of the flows, coefficients which are obtained on the basis of laboratory analyses made earlier from corresponding flows, by using temperature compensation to specify the correlations, and by taking account of the regular variation in the wood composition of fresh wood according to the annual cycle and, as a result, the compositions of the flows are achieved. The present invention decreases the number of chemical analyses and improves the uniformity of the products.

摘要： A control system having four major components: a target optimizer, a path optimizer, a neural network adaptation controller and a neural network. In the target optimizer, the controlled variables are optimized to provide the most economically desirable outputs, subject to operating constraints. Various manipulated variable and disturbance values are provided for modeling purposes. The neural network receives as inputs a plurality of settings for each manipulated and disturbance variable. For target optimization all the neural network input values are set equal to produce a steady state controlled variable value. The entire process is repeated with differing manipulated variable values until an optimal solution develops. The resulting target controlled and manipulated variable values are provided to the path optimizer to allow the manipulated variables to be adjusted to obtain the target output. Various manipulated variable values are developed to model moves from current to desired values. In this case trend indicating values of the manipulated and disturbance variables are provided to produce time varying values of the controlled variables. The process is repeated until an optimal path is obtained, at which time the manipulated variable values are applied to the actual process. On a periodic basis all of the disturbance, manipulated and controlled variables are sampled to find areas where the training of the neural network is sparse or where high dynamic conditions are indicated. These values are added to the set of values used to train the neural network.
