摘要： A process for reducing the rate of increase in pressure drop across a furnace convection section, the furnace convection section having a temperature profile. The process includes the steps of establishing a ratio of total dilution H2O to feedstock for the system, injecting a first portion of the total dilution H2O in the form of water into the convection section of the furnace, injecting a second portion of the dilution H2O in the form of steam into the convection section of the furnace, wherein a ratio of dilution H2O in the form of water to dilution H2O in the form of steam is established and varying the temperature profile across the convection section of the furnace by adjusting periodically the ratio of dilution H2O in the form of water to dilution H2O in the form of steam. A similar technique is conducted during decoking to remove asphaltene coke starting from the lower convection section upward. This upward decoking is accomplished by initially using more H2O in the form of water, then as the decoke proceeds reducing H2O in the form of water while increasing H2O in the form of steam.

摘要： An apparatus and process are provided for cracking hydrocarbonaceous feed, wherein the temperature of heated effluent directed to a vapor/liquid separator, e.g., flash drum, whose overhead is subsequently cracked, can be controlled within a range sufficient so the heated effluent is partially liquid, say, from about 260 to about 540° C. (500 to 1000° F.). This permits processing of a variety of feeds containing resid with greatly differing volatilities, e.g., atmospheric resid and crude at higher temperature and dirty liquid condensates, at lower temperatures. The temperature can be lowered as needed by: i) providing one or more additional downstream feed inlets to a convection section, ii) increasing the ratio of water/steam mixture added to the hydrocarbonaceous feed, iii) using a high pressure boiler feed water economizer to remove heat, iv) heating high pressure steam to remove heat, v) bypassing an intermediate portion of the convection section used, e.g., preheat rows of tube banks, and/or vi) reducing excess oxygen content of the flue gas providing convection heat.

摘要： A process for cracking a light hydrocarbon feedstock containing non-volatile components and/or coke precursors, wherein a heavy hydrocarbon feedstock is added to the contaminated light hydrocarbon feedstock to form a contaminated hydrocarbon feedstock blend which is thereafter separated into a vapor phase and a liquid phase by flashing in a flash/separation vessel, separating and cracking the vapor phase, and recovering cracked product. The heavy hydrocarbon feedstock allows operation of the flash/separation vessel at a higher temperature, within the operating temperature range of the separation vessel.

摘要： An acoustic reflection instrument detects background noise and reflections present in a well bore that extends into the earth. The instrument includes a shot break channel with a fixed gain amplifier, a collars channel with a variable gain amplifier and a liquid level channel with a variable gain amplifier. The outputs of all these amplifiers are input to an analog-to-digital converter which selectively provides digital output signals to a central processing unit which in turn processes the received data and prints it on a strip chart with two channels, one for principally showing reflections from collars and the other channel for principally showing the reflection from the liquid surface. Background noise is measured for a predetermined time to set a gain level for the amplitude of the noise to appear on the strip chart record. After the acoustic pulse is detected by the instrument, the gain of the collars channel is adjusted, first with fixed values and then followed by variable values based upon the peak value within a sample of preceding output data samples. However, the maximum gain of the collars channel amplifier is limited to the gain setting determined for measurement of the background noise. The amplification can also be performed in software. The output signal is printed on a strip chart.

摘要： An oil well pumping unit has a walking beam which raises and lowers a rod connected to a downhole pump. To perform well analysis, it is desirable to know the position of the rod during the stroke. An accelerometer is mounted on the pumping system unit to move in conjunction with the rod. An output signal from the accelerometer is digitized and provided to a portable computer. The computer processes the digitized accelerometer signal to integrate it to first produce a velocity data set and second produce a position data set. Operations are carried out to modify the signal and produce a position trace with stroke markers to indicate positions of the rod during its cyclical operation.
