Modeling of Partially Hydrolyzed Polyacrylamide-Hexamine
In this study, a partially hydrolyzed polyacrylamide-hexamine-hydroquinonegel is used for the development of polymer gel system. The experimental investigation demonstrates that the gelation time varies with polymer and crosslinker concentration and the temperature.
The application of these systems requires careful monitoring of the gelation behavior to avoid premature gelation or prolongs shut-in times under reservoir conditions. The paper deals with the investigation of disproportionate permeability reduction (DPR) of reservoir rock using partially hydrolyzed polyacrylamide–hexamine–pyrocatechol gels.

The cross-linked polymer gels exhibit non-Newtonian rheological behavior which can be described well by the different types of rheological models. This study investigates the onset of gelation behavior of partially hydrolyzed polyacrylamide-hexamine-pyrocatechol polymer gel system which may be used to control excessive water production in the oil fields.

The further breakdown of the dihydrodiol is shown in the pathway, which yields para chloro benzoic acid as its final breakdown product. A Pseudomonas aeruginosa strain degrades mono- and 1,4-dichlorobenzene but can only partially degrade 1,2,4-trichlorobenzene.

- What is poly aluminum-ferric chloride (PAFC)?
- Author to whom correspondence should be addressed. Poly aluminum-ferric Chloride (PAFC) is a new type of high efficiency coagulant. In this study, high iron type gangue is used as a main raw material. It is calcined at 675 °C for 1 h and 3% CaF 2 is added to the calcined powder and reacted with 20% hydrochloric acid at 93 °C for 4 h.

- Do poly aluminum chloride and poly ferric sulfate affect was digestion?
- Poly aluminum chloride (PAC) and poly ferric sulfate (PFS) are widely used in wastewater treatment and sludge dewatering, resulting in their amounts being accumulated substantially in waste activated sludge (WAS). Till now, however, little information about their influence on WAS digestion is available.
- Is polyaluminum chloride a good coagulant for water treatment?
- Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water [ 6 ].
