The invention is directed towards methods and compositions for identifying the amount of hydrofluoric acid in a buffered oxide etching composition. In buffered oxide etching compositions it is very difficult to measure the amount of hydrofluoric acid because it has varying equilibriums and it is toxic so it hard to handle and sample. When used to manufacture microchips however, incorrect amounts of hydrofluoric acid will ruin those chips. The invention utilizes a unique method of spectrographically measuring the hydrofluoric acid when in contact with added chromogenic agents to obtain exact measurements that are accurate, immediate, and safe.

The invention provides methods and compositions for improving the rheology of red mud removed from Bayer Process liquor. The method includes adding a flocculant and a cross-linked polysaccharide to the liquor. This combination separates the red mud from the liquor but also prevents the red mud from becoming too thick. By preventing excessive thickness, the method allows for the formation of extremely dense amounts of red mud even in primary settlers because the dense red mud can still flow. As a result a user can simultaneously enjoy both easy handling of red mud and also high recovery rates of valuable alumina and caustic from the red mud.

A method of rapidly and essentially simultaneously creating and feeding a dispersion into a hydrocarbon process stream. This method allows for the effective use of chemical additives in a hydrocarbon process line that are highly unstable or that are very difficult to disperse. This is especially helpful in hydrofracturing operations as the very rapid flow rates require very fast dispersion formations. As a result the method allows greater fracking pressures which can be obtained with lower energy inputs and by using lessor amounts of chemical additives. As a result hydrocarbon extraction can be accomplished in a manner which is both more environmentally friendly as well as less expensive.

A method for recovering heavy oil or bitumen from an underground reservoir by injection of anhydrous ammonia gas at a temperature greater than the temperature of the reservoir and a pressure such that the ammonia gas fills voids left by recovered oil and condenses to liquid as the gas cools from contact with the reservoir. The ammonia reacts with native naphthenic acids in the oil to form surfactants. These surfactants emulsify the oil into the immiscible liquid ammonia, which flows into a producing well that carries the emulsified fluid to the surface. The fluid may be depressurized to release the oil and recover the ammonia as a gas that may be recycled. The process requires no water supply, no water treatment, no water disposal, less heat than generating steam, and is compatible with oil-wet, acid-soluble, carbonate-type formations.

The invention is directed towards methods and compositions for treating piles of low-rank coal to inhibit its spontaneous combustion. The method involves applying to the low-rank coal a composition containing VAE and crude glycerin. The composition prevents water from evaporating out of the low-rank coal. This prevents the formation within the low-rank coal of hollow openings which are a huge factor in causing its spontaneous combustion. The composition has better performance than its ingredients do alone. In fact it is so effective that certain cumbersome low-rank coal-handling methods, such as FIFO recordkeeping and inventorying, not using pinch points, or only using elbow-free equipment can be disregarded when the composition is used.

Abrégé

The invention embodies the application of different combinations of the monitoring and data processing aspects as a means to develop an early warning chatter alarming system. Configuring an early warning chatter alarming system can be as simple as using nσ alarm settings to develop an alarming strategy from different trend conditions such as overall RMS, selected vibration frequencies, slope analysis, and wavelet analysis. A higher level of alarming is provided by using a time integrated approach to account for both intensity of the alarm variable and duration. Combining these different aspects with a predictive model incorporates process-operating conditions to enhance the alarming sensitivity for earlier detection and reduce false positives. Finally, combining the different alarming aspects with a rule-based decision making approach such as fuzzy logic allows alarming based on qualitative analysis of different data streams. For example, the combination of overall RMS, frequency band, and slope analysis trend data for fuzzification to develop if-then relationships for alarm conditions. Other examples for interpretation using a combination of trend data for alarming include multivariate regression, principle components, and cluster analysis.

Additionally, a method for reducing biological activity in a process stream is disclosed. The method comprises: providing a composition to a process stream, wherein said composition contains: a halogen, urea, and an additional halogen stabilizer excluding urea, optionally an alkali in a concentration sufficient to provide said composition with a pH of greater than 10; and optionally excluding a stabilized bromine compound from said composition. The invention is also directed to compositions and methods of their use as effective biocidal agents for water streams. The composition comprises a halogen source, halogen stabilizers containing a sulfur bearing species and ammonium salts/urea, and an alkali. The sulfur bearing species includes sulfamic acid or its salt equivalent. The ratio between nitrogen mixture of sulfur bearing species and ammonium salts or urea can be optimized at any rate. By having optimized mixing ratio of halogen to stabilizer and that of ammonium salts to sulfamic acid or sulfamate, a synergistic effect occurs which both increases the efficacy of the composition as a biocide and it avoids adverse impacts on other chemicals that are present in the water stream (such as paper additives in pulp and papermaking water streams). Best of all the composition is easy to form and easy to introduce into a water stream of concern. Its introduction can be as simple as mixing two containers of reagent prior to introduction to the water process stream.

Abrégé

The invention directed to a method of reducing the increase in viscosity and the drop in the heat transfer coefficient that commonly occurs with quenching media which is repeatedly circulated through a hot reaction vessel. The method comprises adding a preserving composition to the quenching media. The composition comprises: a) high temperature polymerization inhibitor, b) a tar dispersant, and c) a viscosity reducer. The method allows the quenching media to remain effective longer than would otherwise be the case and thereby prevents problems associated with having to devote excessive resources for controlling heat recovery, viscosity increases, product downgrades or having to operate equipment at temperatures beyond their optimum performance designs.
