Synthesis and evaluation of partially hydrolysed
Drilling mud grade bentonite clay conforming to American Petroleum Institute Specifications, were used as the basic mud building material after hydrating fully. The prepared mud contained about 4% bentonite, 0.2% PHPA, 1.5% sulphonated asphaltene and sufficient amount of barites to make the mud spe- cific gravity 1.2.
With the promotion of the polymer oil-displacing technology in China, polyacrylamide (PAM) are widely used in the exploitation of oil. Biodegradation of partially hydrolyzed polyacrylamide (HPAM) may be an efficient way to treat oilfield sewage, because part of the amidogen and carbon of the HPAM could be utilized as the source of nitrogen and carbon nutrition for the growth of microorganism
PHPA (Partially Hydrolyzed Polyacrylamide) - Manufacturer
The partially hydrolyzed polyacrylamide works by reducing the fluid mobility through increasing the viscosity or reducing permeability of the oil recovery drive fluid. With this process, the polymer acts as a fluid flow blocking agent. Apart from oilfield application, this polymer is also popularly used in flood areas to restrict water flow.
PHPA (Partially Hydrolyzed Polyacrylamide) The provided PHPA (Partially Hydrolyzed Polyacrylamide) is processed with utmost care using the best in class chemical compounds at our sophisticated laboratory. It is widely used for enhancing inhibition properties to fresh as well as sea water to be used in numerous industrial processes.
Treatment of produced water mixed with polymer - NASA/ADS
In the petroleum industry, polymer flooding is one of the main methods in enhanced oil recovery (EOR) that applies a water-soluble polymer such as partially hydrolyzed polyacrylamide (HPAM) to increase oil production. It is added to the flooding water to improve the oil movement. During the process, water is produced as a by-product along with oil and gas production.
The increasing usage of partially hydrolyzed polyacrylamide (HPAM) in oilfields as a flooding agent to enhance oil recovery at so large quantities is an ecological hazard to the subsurface ecosystem due to persistence and inertness. Biodegradation of HPAM is a potentially promising strategy for dealing with this problem among many other methods available.

Influences of partially hydrolyzed polyacrylamide (HPAM) residue on the flocculation behavior of oily wastewater produced. The influences of temperature and concentration of partially hydrolyzed polyacrylamide (HPAM) residue on the treatment of simulated oily wastewater from polymer flooding were studied in this paper.

improvement, compared to free enzyme treatment (9.7 卤 3.3%). In summary, a novel approach for degrading partially hydrolyzed polyacrylamide was investigated using hydrogen peroxide and horseradish peroxidase. This sustainable HRP/H 2 O 2 system degraded the polymer in solution, reducing its viscosity and molecular weight.

- Is polyaluminum ferric chloride an inorganic coagulant?
- 1. Introduction Polyaluminum ferric chloride (PAFC) is an efficient inorganic polymeric coagulant [1], [2]. Many studies [3], [4], [5] have demonstrated that inorganic polymeric coagulants were more effective than conventional inorganic coagulating salts in coagulation due to their resistances to the influence of wastewater initial pH.
- What is poly aluminum-ferric chloride (PAFC)?
- See Materials (Basel). 2025 April 25; 15 (9): 3104. 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.
- What is the coagulation time for aluminum sulfate and aluminum chloride coagulants?
- However, for aluminum sulfate and aluminum chloride coagulants the coagulation time and settling time were reached to 15 and 35 min, respectively. The results revealed that the residual aluminum concentration in the treated water was very small for synthesized PAC coagulant which was <0.2 mg L −1.
