摘要： An improved liquid hydrocarbon feed method is disclosed wherein substantially all of the liquid is converted to mist sized particles over a wide angled dispersion pattern without a concurrent shroud of steam or water. Such dispersion promotes vapor phase catalytic reaction between hydrocarbon vapors and fluidized catalyst in a reaction time of 1 to 3 seconds. The misting nozzle is characterized by a swirl chamber to which the full hydrocarbon feed, with or without steam included in the feed, is supplied for centrifugal rotation by vane members to form a free vortex. The flow is then released through a reduced area square-edge orifice having a short throat to form and maintain a characteristic "vena contrata" from such an orifice during flow into the catalyst stream in the riser reactor for dispersion over a wide angled conical dispersion pattern. Such flow from the orifice allows the nozzle to be recessed out of the flowing catalyst stream. This keeps the nozzle cooler and minimizes mechanical erosion of the nozzle by the flowing, heated catalyst, without use of two phase nozzles to separately add steam or water. However, if desired steam may be used as a portion of the single fluid flow from the nozzle to reduce partial pressure of the vaporizing hydrocarbon feed. In a preferred form, the liquid feed is introduced into the transition section of a riser reactor.
摘要翻译：公开了一种改进的液体烃进料方法，其中基本上所有的液体在宽角度的分散图案上转化成雾化尺寸的颗粒，而没有蒸汽或水的同时的罩。这种分散促进烃蒸气和流化催化剂之间的气相催化反应，反应时间为1至3秒。雾化喷嘴的特征在于一个涡流室，进料中包含或不含有蒸汽的全烃进料被供应用于叶片构件的离心旋转以形成自由涡流。然后通过具有短喉部的减小面积的方形边缘孔释放流动，以在流入提升管反应器中的催化剂流中时从这种孔口形成并保持特征性“再生”，以在宽角锥形分散图案上分散。来自孔口的这种流动允许喷嘴从流动的催化剂流中凹入。这样可以使喷嘴更冷却，并且通过流动的加热催化剂使喷嘴的机械腐蚀最小化，而不使用两相喷嘴分别加入蒸汽或水。然而，如果需要，蒸汽可以用作来自喷嘴的单一流体流的一部分，以减少汽化烃进料的分压。在优选的形式中，液体进料被引入提升管反应器的过渡部分。

摘要： An improved method and apparatus for determining injection profiles in a steam injection well is disclosed. The mass flow rate and quality of steam entering the well is measured. A well logging tool is then used to measure temperature and/or pressure profiles within the perforated zone of the well. A liquid phase tracer is then injected for a short time into the well with the steam. The well logging tool contains dual gamma ray detectors and is used to measure the transit time of the tracer slug. In the preferred embodiment, the liquid tracer is radioactive elemental iodine or sodium iodide. The procedure is repeated with a vapor phase tracer which is radioactive Krypton, Argon, or Xenon in the preferred embodiment. A vapor and liquid profile can then be calculated with simple mass balance equations. In a second approach, a spinner survey and a single tracer survey are conducted. By combining the spinner and tracer survey results, vapor and liquid rates can be determined and steam injection profiles can be calculated.

摘要： A method of avoiding stuck drilling equipment during drilling of a well over depth intervals where such equipment has stuck in similar wells in a geological province. A multiplicity of well drilling variable quantities are measured substantially simultaneously at a known depth in each of a multiplicity of wells. Such multiplicity of wells includes those in which drilling equipment has stuck due to mechanical problems or differential pressure between the drill string and an earth formation penetrated by the well bore, or both, and a multiplicity of similar wells where the drill string did not stick. By multivariate statistical analysis of all variables in all wells of each class, together with maximum separation of said classes from each other, a plotting plane for a currently drilling well relative to said classes is established. The location of the relative position of all variables in such a drilling well with respect to the well classes is determined by summing the products of the coefficient of each variable for the complete group of wells times the current value of the variables in the drilling well. The variables are then modified within allowable values to change the plotted location of the drilling well toward the mean of the wells that did not stick the drill string.

摘要： A method is disclosed for reducing the sulfur deposition in the absorber of a Stretford process. In the Stretford process, hydrogen sulfide is removed from a gas stream by contacting the gas stream in an absorber with a circulating aqueous solution to convert the hydrogen sulfide to elemental sulfur particles, passing the solution containing the sulfur particles to a reaction vessel where the conversion of hydrogen sulfide to sulfur is completed, passing the solution containing the sulfur particles to an oxidizer, oxidizing the solution containing the sulfur particles in the oxidizer to form a regenerated solution, separating the sulfur particles from the regenerated solution, and recirculating the solution to the absorber. The sulfur deposition in the absorber is reduced by adding about 300 ppm of a hydroxyquinone compound, such as 1-hydroxyanthraquinone (1-HAQ); 1,2-dihydroxyanthraquinone (1,2-DHAQ); 1,8-dihydroxyanthraquinone (1,8-DHAQ); 1,2-dihydroxyanthraquinone 3-monosulfonic acid (1,2-DHAMA); 1,2,5,8-tetrahydroxyanthraquinone (1,2,5,8-THAQ); 1,4,5,8-tetrahydroxyanthraquinone (1,4,5,8-THAQ); 5- hydroxy 1,4-naphthoquinone (5-HNQ); or a mixture thereof, to the absorber.
