Abstract

A process for improving yield of kerosene from a renewable feedstock involves directing a hydroprocessed liquid stream to a lead stripper to separate a lead stripper bottoms stream and a lead stripper overhead stream comprising naphtha, lower and higher boiling point range hydrocarbons and water. Bulk water is removed from the lead stripper overhead stream resulting in an unstabilized hydrocarbon stream, which is passed to a stabilization column to separate a stabilized naphtha-containing stream from the lower boiling point range hydrocarbons. The stabilized naphtha-containing stream is passed to a rectification column to separate a rectification bottoms stream and a naphtha product stream. Kerosene and diesel boiling range product streams are separated from the lead stripper bottoms stream in a vacuum fractionator.

Abstract

A process for producing kerosene involves reacting a renewable feedstock in a hydroprocessing section under hydroprocessing conditions sufficient to cause a hydroprocessing reaction to produce a hydroprocessed effluent. The hydroprocessed effluent is separated to produce a hydroprocessed liquid stream and a separation system offgas stream. The hydroprocessed liquid stream is directed to a work-up section where gases are stripped to produce a stripped liquid product stream and a stripper offgas stream. A gas stream comprising the separation system offgas stream and/or the stripper offgas stream are directed to a gas-handling section to obtain a pressurized gas stream and a hydrocarbon fraction that is liquid at a pressure in a range from 0 - 1.5 MPaG and a temperature in a range from 0 to 50C. The hydrocarbon fraction is recycled to the work-up section. A kerosene stream separated in the product recovery unit has a higher yield compared to conventional processes.

Abstract

A process for hydroprocessing a renewable feedstock in a fixed-bed reactor system having at least one catalytic bed involves directing a downward flow of the renewable feedstock to a filtering zone having top-open interstitial portions to receive the downward flow and top-covered annular portions that are in fluid communication with a headspace between the filtering zone and a catalytic zone. The feedstock flows from the interstitial portions to the annular portions through a filtering material disposed between the interstitial portions and the annular portions, resulting in a filtered feedstock, which then flows to the catalytic zone. In the catalytic zone, filtered feedstock is reacted under hydroprocessing conditions sufficient to cause a reaction selected from the group consisting of hydrogenation, hydrodeoxygenation, hydrodenitrogenation, hydrodesulphurization, hydrodemetalation, hydrocracking, hydroisomerization, and combinations thereof.

Abstract

Bottom hole pressure (BHP) actuals and bottom hole temperature (BHT) actuals in a hydrocarbon production well are recorded as a function of time, during production of hydrocarbon fluids. Selective statistical measures of both the BHP actuals and the BHT actuals are determined as a function of time. These selective statistical measures suitably represent estimates of expected normal BHP actuals and BHT actuals in case there is no imminent sand failure, supplemented with an uncertainty measure of the estimates of expected normal BHP and BHT. The BHP actuals and the BHT actuals are compared with respective BHP and BHT anomaly thresholds based on the selective statistical measures. An anomaly alert is automatically issued upon meeting a condition wherein both the BHP actuals and the BHT actuals exceed their respective anomaly threshold. The anomaly alert is an indication of a predicted imminent sand failure of the hydrocarbon production well in operation.

The epoxidation catalyst comprises silver and a promoting amount of rhenium (Re), and the measured reactor selectivity (Smeas), the measured reactor temperature (Tmeas), and the one or more operational parameters comprise real-time and historical operating data points over time generated by the ethylene oxide production system. The method also includes using a processor to (a) calculate, using a model, for each time point, a model-estimated selectivity (Sest) and a model-estimated temperature (Test) of the epoxidation catalyst at an optimum moderator level (Mopt). The model-estimated selectivity (Sest) and the model-estimated temperature (Test) are determined based on at least one operational parameter of the one or more operational parameters at said time points, the at least one operational parameter does not include a moderator level, and the model is based, at least in part, on empirical historical data associated with the epoxidation catalyst, the ethylene oxide production system, or both. The method also includes using the processor to (b) determine a difference (?S) between the measured reactor selectivity (Smeas) and the model-estimated selectivity (Sest) and a difference (?T) between the measured reactor temperature (Tmeas) and the model-estimated temperature(Test) for each of the time points, (c) fit a curve to the delta selectivity (?S) data points as a function of the corresponding delta temperature (?T) data points to obtain a fitted curve, (d) determine a real-time relative effective moderator level (RCleffreal-time) based on the fitted curve and real-time values of ?S (?Sreal-time) and ?T (?Treal-time) and (e) output an actionable recommendation based on the real-time RCleff.

Abstract

A process for hydroprocessing a renewable feedstock involves introducing the renewable feedstock and hydrogen in a downward flow into a top portion of a fixed-bed reactor and distributing the downward flow to a top surface of a first catalyst bed in a manner such that the top surface is uniformly wetted across the reactor cross section. The feedstock then flows downwardly through the first catalyst bed, where it is reacted under hydroprocessing conditions sufficient to cause a reaction selected from the group consisting of hydrogenation, hydrodeoxygenation, hydrodenitrogenation, hydrodesulphurization, hydrodemetallization, hydrocracking, hydroisomerization, and combinations thereof. A hydrocarbon liquid separated from the reaction effluent is recycled to the renewable feedstock in a ratio of 0.4:1 to 1.8:1, based on the volume of the renewable feedstock.

Hydrogen is also an important fuel for future transportation and other uses as it does not generate any carbon dioxide emissions when used. The invention provides for a process for producing hydrogen comprising the steps of partially oxidizing a hydrocarbon to obtain a synthesis gas, providing the synthesis gas to a reactor in which carbon monoxide is converted to carbon dioxide, removing the carbon dioxide to obtain hydrogen. The carbon dioxide is used in a chemical process and/or stored in a geological reservoir.

Abstract

The present application relates to a method for estimating the temperature rise rate of a battery under pulsed heating. By establishing an equivalent circuit model of the battery, parameters in the equivalent circuit model of the battery are identified to obtain the effective entropy potential of the battery and the relationship between the open circuit voltage and the pulsed heating current of the battery. The amplitude and period of the pulsed heating current are pulsed parameters. Then according to the effective entropy potential and the relationship between the open circuit voltage and the pulsed heating current of the battery, a heat generation model is established. By using the heat generation model and the heat transfer power of the battery, an energy formulation of the battery in the process of pulsed heating is obtained, so as to obtain the temperature rise rate of the battery under pulsed heating. By establishing an equivalent circuit model of the battery and using the heat generation model of the battery and the heat transfer power model of the battery, the foregoing method can obtain the relationship between the temperature rise rate of the battery under pulsed heating and the pulsed heating current, providing a convenient and comprehensive estimation method for determining the heating effect of pulsed heating in practical applications.

Abstract

The present application relates to a method and system for determining parameters of battery pulsed heating. The reference potential of the anode of the lithium-ion battery is obtained in real time in the positive and negative pulsed heating process under various heating parameters. The reference potential of the anode is the voltage difference between the anode of the lithium-ion battery and the reference electrode. By judging the relationship between the reference potential of the anode and the threshold potential, it is judged whether Li plating has occurred to the lithium-ion battery. Li plating may lead to a decrease in the available capacity of the battery, and puncture of the membrane by dendrite, which causes a short circuit in the battery and induces thermal runaway of the battery, bringing about many hazards such as performance reduction and safety risks. Therefore, when the reference potential of the anode is smaller than the threshold potential, the first heating parameters need to be adjusted to avoid the occurrence of Li plating and improve the life of the battery. By recording the heating parameters when the reference potential of the anode is greater than the threshold potential, it can be ensured that the pulsed heating parameters have no significant impact on the life of the battery.

Abstract

The present application relates to a durability test method and system and a data table generation method for battery pulsed heating. The battery to be tested is put into a temperature chamber, and the temperature of the temperature chamber is set at a first temperature value. The lithium-ion battery is subjected to pulsed heating under first pulse parameters until the pulsed heating time reaches the preset pulse duration. The temperature of the temperature chamber is adjusted to a second temperature value and a capacity degradation value of the battery to be tested is obtained at the second temperature value, so as to obtain durability of the battery to be tested. Before testing of the capacity degradation value of the battery to be tested, continuous pulsed heating is conducted. After the battery is heated for a period of time, the temperature elevation and heat dissipation of the battery will reach stable values and the temperature will no longer rise. Such pulsed heating does not require a long period of standing at low temperature. Therefore, a large amount of test time can be saved, the test period is shortened, and the influence of battery temperature on battery durability can be verified through a large number of experiments.
