Exxon products

Exxon products appear to release via a unique mechanism. Like other polymer-coated technologies, the penetration of water iato the granule is purely by diffusion. However, as water enters the particle, an osmotic pressure is created as the fertilizer is solubilized. This pressure causes an expansion of the elastomeric coating and the particle swells to many times its original diameter. As the particle swells, the coating becomes increasingly thinner to the point where it caimot contain the internal pressure and the nutrient is released. 

AgronomicaHy, Exxon products have been successful on a number of crop appHcations under varied climatic conditions from the plains of Canada to the heat and humidity of Elorida.

I first encountered reaction modeling in 1980 when working in Houston at Exxon Production Research Company and Exxon Minerals Company. There, I read papers by Harold Helgeson and Mark Reed and experimented with the programs EQ3/EQ6, written by Thomas Wolery, and Path, written by Ernest Perkins and Thomas Brown. 

Company, Arco Oil and Gas Company, Chevron Oil Field Research Company, Exxon Production Research Company, the Mobil Foundation, Shell Development Company, and the Standard Oil Company. Discussions with W.J. Benton on various aspects of the experimental techniques were most helpful. 

Basil Philhps (Exxon International Co.) and D. E. Brandon (Exxon Production Research Co.) assisted in developing the sampling procedures. W. Broecker and John Goddard of the Lamont-Doherty Geological Observatory of Columbia University helped to evaluate profile sampling and other aspects of the work. Laboratory work was carried out by D. E. Bachert and W. D. Henriques. 

This work was supported by grants from Shell Development Company, Exxon Production Research Company, Amoco Production Company, and Gulf Research and Development Company. K. Raney thanks Cities Service Company for personal financial support during the period this work was performed.

This work was supported in part by the Office of Naval Research. The authors also wish to express their appreciation to Dr. John Longo of Exxon Production Research for helpful discussions. 

Two commercial viscometers were used at higher shear stresses a Rheometrics Mechanical Spectrometer with sensitive transducer (data kindly provided by P. J. Whitcomb of General Mills Chemicals Co.), and a Contraves instrument (data kindly provided by W. Gale and B, Boseck of Exxon Production Research Co.). Viscosity standards from Cannon Instrument Co. were used to check the Contraves instrument. 

Fig. 31. Strong enrichment in Eu in strata-bound massive Pb-Zn ore deposits at Mt. Isa, compared to normal shales. The enrichment is related to hydrothermal activity during ore-body formation. Similar enrichment in Eu, shown in the two lower patterns, is observed in sulfides being precipitated at submarine black smokers at a mid-ocean ridge crest. [Data by courtesy of Mt. Isa Mines, Dr. A.E. Bence, Exxon Production Company, Houston, TX, USA, and from Bence (1983).]...

Fiocco and coworkers demonstrated the use of two dispersant apparatuses to test demulsifiers, the WRASET , which uses the wrist-action tester or EXDET test, and the ROFLET , which uses the rolling flask or Warren Springs test [J6S], To demonstrate the test, an emulsion with Kuwait crude oil was used with the Exxon products, Breaxit OEB-9, 7877, 8150, and 8160, and the surfactant dioctyl sulfosuccinate. Effectiveness was measured by visually observing the amount of water/oil separation. A Sture blend crude was used to evaluate the same demulsifiers plus Ameroid 372101, Breaxit 4018, 711, 7125, 7128, and 7652, as well as Shell LA 1834, Alcopol 60, and a demoussifier . Ameroid was found to be the best product, followed closely by Breaxit 4018, 7111, 4018, and then LA 1834.

A brominated butyl rubber can be prepared in a manner similar to the chlorinated version. Bromobutyl is structurally similar to chlorobutyl but contains approximately 2.0 wt % bromine (in the case of the Exxon product) and provides an additional level of crosslinking activity. ...
