The present disclosure is directed to surfactants (in particular olefin sulfonates), surfactant packages, compositions derived thereof, and uses thereof in hydrocarbon recovery. Methods of making olefin sulfonate surfactants are also described.

A process for preparing an alcohol ether sulfate is disclosed which comprises: (a) sulfating an alkoxylated alcohol; and (b) neutralizing the sulfated product of step (a) in the presence of a base and a co-solvent having a flash point of at least 60&#xb0; C.

Systems and methods for determining a display device's behavior based on a dynamically-changing event associated with another display device are disclosed. In one example, a peer-to-peer distributed data network system comprises a first display device that operates a peer-to-peer distributed system application, which detects a dynamically-changing event associated with a second display device to either maintain or change the first display device's current behavior. In one example, the dynamically-changing event is a change of display content, new sensory information, or another new event for the second display device. If the peer-to-peer distributed system application determines that the dynamically-changing event of the second display device merits a change in the first display device's current behavior, the first display device's current behavior may be replaced by a new device behavior, such as switching from a currently-shown content or a user interface menu to a different content or a different menu.

In a process for forming a bulk hydroprocessing catalyst by sulfiding a catalyst precursor made in a co-precipitation reaction, up to 60% of the metal precursor feeds end up in the supernatant. The metals can be recovered via any of chemical precipitation, ion exchange, electro-coagulation, and combinations thereof to generate an effluent stream containing less than 50 mole % of metal ions in at least one of the metal residuals, and for at least one of the metal residuals recovered as a metal precursor feed for use in the co-precipitation reaction. In one embodiment, the resin functions as an anion exchange resin with an acidic supernatant to recover Group VIB metal residuals, and a cation exchange resin with a basic supernatant to recover Promoter metal residuals. An effluent stream from the process to waste treatment contains less than 50 ppm metals.
