Surfactant Adsorption in Surfactant-Polymer Flooding
This paper presents the results of a laboratory study on the effect of polymer on reducing the surfactant adsorption onto carbonate reservoir cores. An amphoteric surfactant and a sulfonated polyacrylamide were used in three series of dynamic adsorption tests conducted at reservoir conditions, including surfactant only, polymer followed by
The increase in viscosity, adsorption of polymers onto the reservoir rock presents a limitation for the use of polymers. Adsorption of polyacrylamide (PAM) has been extensively studied [10, 14]. Non-hydrolyzed polyacrylamide adsorption onto kaolinite was studied as a function of electrolyte concentration [10, 14].
Sulfonated polyacrylamide adsorption onto carbonate
Adsorption behavior of sulfonated polyacrylamide solutions onto carbonate reservoir rock at high temperature were investigated . The influence of salinity was investigated .
The adsorption of sulfonated polyacrylamide (SPAM) as an enhanced oil recovery polymer onto carbonate rock particles was studied using UV-visible spectroscopy. The effect of the experimental parameters of polymer concentration, salinity and temperature was investigated. The results showed that polymer adsorption increased as the SPAM concentration increased, but decreased as temperature and

The most valuable merit of soft decontamination techniques is a low volume of the resulting RAW. With most of the hard methods, the whole loop had to be filled successively with two or three decontamination solutions and repeated rinsing baths, so that the resulting effluents made up as many as 20 volumes of the entire circuit.

Systematic experiments were performed to determine the adsorption capacity of PAF-45 for PFOS and to characterize the kinetics of the adsorption process. The adsorption of PFOS onto PAF-45 reached equilibrium in 30 min, and the adsorption capacity of PAF-45 for PFOS was excellent (5847 mg g(-1) at pH 3).

- What is a containerized mobile wastewater treatment plant?
- A containerized mobile waste water treatment plant is a packaged wastewater treatment system where all wastewater treatment equipment is completely preinstalled in ISO shipping containers. We are market leaders in the manufacture of containerised, modular solutions, with projects completed all over the world and across many different sectors.
- What is Pine Creek wastewater treatment plant (WWTP)?
- The Pine Creek Wastewater Treatment plant was officially unveiled in May 2010. The City of Calgary officially unveiled its advanced Pine Creek Wastewater Treatment Plant (WWTP) in May 2010. Built at a cost of $430m, the new plant is one of the most technologically advanced and environmentally friendly facilities in Canada.
- What are Canada's New wastewater management regulations?
- New wastewater management regulations in Canada require all primary treatment plants in urban areas to upgrade to secondary treatment by 2025. The new regulations affect about one out of every four wastewater treatment systems across the country.
- How much does a new wastewater treatment plant cost?
- Built at a cost of $430m, the new plant is one of the most technologically advanced and environmentally friendly facilities in Canada. The facility can treat up to 100 mega-litres of wastewater per day (ML/d) to serve a population of 250,000 for the next 10 years.
