“…Recently, research to find new inhibitors compatible with the environment is underway, using the so-called green inhibitors, according to three criteria: Toxicity, bioaccumulation, and biodegradation [17][18][19]. To go further with this aim, this work focuses on new bio-inhibitors, for reducing the scaling deposits formed by Bounouara ground water, which supplies the entire southern region of the Constantine city in Algeria and is characterized by 60 ∘ f hardness.…”

In this study, agricultural waste was utilized as new bio-inhibitors to prevent scale formation in hard waters. Aqueous extracts of strawberry and tomato leaves were utilized for reducing the scale deposits formed on metallic surfaces by Bounouara ground hard water, which supplies Constantine city in Algeria. Anti-scaling properties were evaluated by chronoamperometry and impedancemetry techniques. The effect of temperature and concentration on the efficiency of the bio-inhibitors was assessed. The results showed that the anti-scaling effect of strawberry leaf extracts started at the very low concentration of 1 ppm, with 31% efficiency, reaching complete scaling inhibition at 15 ppm (20ºC), whereas the inhibitory effect of tomato leaf extracts was noticed at 2.5 ppm, with 36% efficiency, and total inhibition at 20 ppm (20ºC). The efficiency of strawberry and tomato leaf extracts at 40∘C was also confirmed, although total inhibition was attained at a higher concentration.

“…There had also been a long-standing effort to develop a Chemical Hazard Assessment and Risk Management (CHARM) model, with support from the European Oilfield Specialty Chemicals Association (EOSCA). This resulted in hazard ranking lists of offshore chemicals on a single substance basis, which did not include the exposure caused by the discharges and the sensitivity of the aquatic environment (Still 2002, Thatcher andPayne 2002). In Norway, therefore, the operators focused on developing a more advanced model for performing environmental impact assessments.…”

Petroleum activities are associated with high risks. In the 1980s, concerns arose about the environmental impacts of 'normal' petroleum activity. Regular operations go hand-in-hand with emissions to air and discharges to sea. Both have been subject to extensive regulation since the 1990s. This paper analyzes the design and implementation of the Norwegian system that regulates operational discharges to the marine environment. It analyzes the changing relationships among science, politics and the industry and describes how the turn from a prescriptive to a predominantly performance-based approach was fundamental in making progress toward less polluting practices. The article describes how risk regulation was institutionalized and highlights the benefits of involving the industry in the pursuit of environmental protection. It also cautions against a lax attitude toward control and oversight, as complexification of risk objects and the increase of institutional risks can lead to mismatches in risk management.

“…Operators sometimes adopt these guidelines for other offshore areas which do not have sufficient environmental guidelines in order to maintain standards of low environmental impact. The OSPAR guidelines were implemented in 2001 under a Harmonised Mandatory Control Scheme. − Norway and Denmark interpret the OSPAR guidelines somewhat differently to the U.K. and Netherlands, with more emphasis on biodegradation. The environmental authorities in the two Scandinavian countries require new chemicals to have over 60% biodegradation by the OECD306 seawater test in 28 days (BOD28) and preferably continued biodegradation after this time.…”

Kinetic hydrate inhibitors (KHIs) have been used in the upstream petroleum industry for about 25 years to prevent plugging of flow lines with gas hydrates. The main ingredients in current commercial KHI formulations are one or more water-soluble polymers which contain both hydrophobic and hydrophilic functionalities. Although the vast majority of KHIs are low in acute toxicity and bioaccumulation, very few commercial products show good biodegradability, and for that reason, there is always some concern of long-term chronic toxicity from partially degraded products if discharged into the environment. This report reviews all efforts to develop more biodegradable KHIs, and outlines the fact that some classes of so-called "green" chemicals are not necessarily readily biodegradable or low in toxicity. The review also covers methodologies to recover or destroy KHIs and reduce their discharge to the environment.
