Osmotic And Mean Activity Coefficients Of Libr And Lic In Methanol At 25, 35, And 45 Degrees C, Peggy Tomasula
Osmotic And Mean Activity Coefficients Of Libr And Lic In Methanol At 25, 35, And 45 Degrees C, Peggy Tomasula
Theses
Vapor pressure depression data of LiBr and LiCl in methanol at temperatures of 25,35, and 45°C were measured in the molality range 0.1-4.4m using a static method, where the difference in vapor pressure of the electrolytic solution is compared to that of pure methanol.
Osmotic coefficients were calculated from the vapor pressure data. This data was then correlated with both the one parameter Bromley equation and the three parameter Pitzer equation. For all systems at all temperatures, the data were better correlated by the Pitzer equation than with the Bromley equation. Mean activity coefficients of the two salts at the …
The Recovery Of Methanol From The Mother Liquor Of A Pharmaceutical Active Ingredient, Richard Lawrence Eichholtz
The Recovery Of Methanol From The Mother Liquor Of A Pharmaceutical Active Ingredient, Richard Lawrence Eichholtz
Theses
The company has been sending to the sewer the filtrate from one of our chemical processes. This filtrate contains 63 vol. % methanol. The recovery of this methanol would reduce the amount of purchased methanol. The recovery would also reduce the Biological Oxygen Demand of the plant effluent. In the near future the local sewer authority will be billing the company for BOD.
The goal of the recovery process is to obtain methanol of satisfactory quality for reuse in the process from which it came. A literature search and a laboratory study verified the non-ideality of the system. Preliminary calculations …
The Optimization Of A Catalytic Methanol Reactor Using Quench Feed, John Paul Mcburney
The Optimization Of A Catalytic Methanol Reactor Using Quench Feed, John Paul Mcburney
Theses
The production of methanol in a catalytic quench feed reactor is studied by means of a computerized model and optimized in terms of total reactor length necessary to achieve a given production rate. The methanol reaction rate can be maximized in a quench reactor through the use of cold stream feeds along the length of reactor.
Since the methanol reaction temperature is restricted to an upper limit of 405°C, the addition of cold stream feed along the adiabatic reactor enables the desired conversion to be reached. For two given levels of conversion, 12% and 15%, an optimum inlet temperature, quench …

The Optimization Of A Catalytic Methanol Reactor, Peter Wrampe
Theses
The development of a computer program which determines the minimum space time of the methanol synthesis reactants is presented. Also, the optimum temperature profile along the catalytic reactor was predicted for a desired conversion at a given operating pressure, feed composition, and catalyst effectiveness factor.
The equilibrium conversion of methanol was determined at various reaction parameters. Rates of reaction were ascertained and maximized with respect to temperature for various conversions and given reaction parameters. The results, along with those obtained when the design equation was numerically integrated, were compared to published data. Equations were established for various sets of published …
