Physical and Chemical Properties of the Petroleums of the San Joaquin Valley of California

Description: From Introduction: "This bulletin is the second report so far published and deals primarily with the large oil fields of the San Joaquin Valley of California. The work will be continued as rapidly as possible, and will include all of the more important petroleum districts of the United States. The prime object of the investigations was to determine the economic value of the petroleums and natural gases in the United States with especial reference to the supplies in the public lands, and to ascertain how these resources could be utilized in the industries with least waste and greatest efficiency.

The Analytical Distillation of Petroleum and its Products

Description: From Introduction: "The Bureau of Mines has studied apparatus and procedure for the distillation analysis of petroleum, and this report is presented as a record of developments up to the present time. The work is incomplete, but the extensive information that has been obtained to date is made available as a guide in handling laboratory distillation problems."

Scale Control With Graphite Heat-Transfer Tubes of Controlled Permeability to Steam

Description: From Introduction: "The present project authorized under OSW Contract No. 14-01-0001-685 was undertaken to investigate the feasibility of controlling calcium sulfate scale by permission of condensate through graphite heat-transfer tubes. Specifically, the following tasks were accomplished during the course of this contract: Graphite tubes 108" long X 2" O.D. x 1 1/2" I.D. were manufactured at three permeability levels. A test apparatus was constructed and proved out as a useful and reliable probe. Tests were conducted at two brine concentrations. Some correlation of test considerations with scale formation was found. The economic practicality and the feasibility of using permeable tubes for desalinization were established."

Analytical procedures for the plutonium Metal Fabrication Process

Description: A report describing a the results of a fluorimetric and volumetric method for the determination of fluoride. This method was developed for the determination of ionizable fluorine in gases in the range of 1-500ppm. This method was chosen because the determination depends on the generation of a color rather than the bleaching effect or on a change of color.

Vapor Compression with Secondary Heat-Transfer Media

Description: From Introduction: "The use of a secondary heat-transfer media in a vapor-compression distillation unit was suggested for investigation as a process for saline water conversion because previous studies on the vapor-compression cycle at low temperatures showed that the fixed charges on the compressor are a substantial part of the final water-product cast. Other fluids were evaluated as above, the results of which are shown in table 1. Data on the other fluids shown in table 1 will be found in the appendix."

Research on Vapor Reheat And Liquid-Liquid Heat Exchange

Description: From Forward and From Introductory- Summary : "This is the seventy-eighth of a series of reports designed to present accounts of progress in saline water conversion with the expectation that the exchange of such data will contribute to the long-range development of economical processes applicable to large-scale, low-cost dimineralization of sea or other saline water. The distillation system has operated with only minor difficulties. Mass transfer coefficients are in the range predicted from previous experiments. It is emphasized that the data reported above are not the best values obtained, but rather those upon which there is statistical justification based upon analysis of all the data."

Second Annual Report: Operation of the Muti-Stage Flash Distillation Plant, San Diego, California

Description: From Introduction: "The Office of Saline Water (OSW) maintains the MSF Module at the San Diego Test Facility, Chula Vista, California, for the purpose of further advancing and developing the state of art of the multistage flash distillation process and thereby reduce the cost of seawater conversion. The MSF Module has been built and operated to obtain engineering design and operating data to serve as a basis for: a. Future process development. b. Improved full scale plant design. Improved full scale plant operating conditions."

Capacity Factors in the Performance of Perforated Plate Distillation Columns

Description: From abstract: "A study of factors affecting the vapor handling capacity of perforated plate liquid-vapor contacting columns. Vapor phase pressure drop across plates, liquid entrainment upward from plate to plate, and plate stability were investigated as functions of operational and geometric column parameters."

Investigation of Multistage Flash Phenomena in a Three-Stage Test System

Description: From Introduction: "This report covers the information resulting from these tasks and additionally the solution to a serious difficulty in obtaining stable operation and reasonable distillate purity due to foaming and priming which was much more serious in three stage test device than it had been in the original two-stage unit."

Comparison of Advanced Distillation Control Methods, Final Technical Report

Description: Detailed dynamic simulations of three industrial distillation columns (a propylene/propane splitter, a xylene/toluene column, and a depropanizer) have been used to evaluate configuration selections for single-ended and dual-composition control, as well as to compare conventional and advanced control approaches. In addition, a simulator of a main fractionator was used to compare the control performance of conventional and advanced control. For each case considered, the controllers were tuned by using setpoint changes and tested using feed composition upsets. Proportional Integral (PI) control performance was used to evaluate the configuration selection problem. For single ended control, the energy balance configuration was found to yield the best performance. For dual composition control, nine configurations were considered. It was determined that the use of dynamic simulations is required in order to identify the optimum configuration from among the nine possible choices. The optimum configurations were used to evaluate the relative control performance of conventional PI controllers, MPC (Model Predictive Control), PMBC (Process Model-Based Control), and ANN (Artificial Neural Networks) control. It was determined that MPC works best when one product is much more important than the other, while PI was superior when both products were equally important. PMBC and ANN were not found to offer significant advantages over PI and MPC. MPC was found to outperform conventional PI control for the main fractionator. MPC was applied to three industrial columns: one at Phillips Petroleum and two at Union Carbide. In each case, MPC was found to significantly outperform PI controls. The major advantage of the MPC controller is its ability to effectively handle a complex set of constraints and control objectives.
