Scavengers are crucial in the oil and gas industry for maintaining operational efficiency and safety by removing harmful contaminants. A S Harrison & Co offers a range of advanced scavengers designed to tackle specific challenges in oil and gas production environments.
The GSW Series consists of concentrated organic sulfide scavengers that rapidly combine with hydrogen sulfide (H2S) in both aqueous and gas systems. These scavengers are essential for controlling H2S levels, which can be highly toxic and corrosive. By effectively neutralising H2S, the GSW Series helps ensure safer and more efficient production processes.
OSW-Oxygen Scavenger is specifically formulated to remove dissolved oxygen from freshwater or brine systems. Oxygen can cause significant corrosion issues in oilfield equipment, leading to costly repairs and downtime. By eliminating dissolved oxygen, OSW-Oxygen Scavenger protects equipment and extends its operational lifespan.
Sulfur Purge™ is designed to significantly reduce the H2S content in middle distillate and residue fuel oils. High levels of H2S in fuels can lead to severe corrosion and safety hasards. Sulfur Purge™ ensures that the H2S content is minimised, improving the safety and quality of the fuel.
TruClean 2000™ is a versatile scavenger used for removing dissolved H2S, iron, and other contaminants. This product is ideal for comprehensive clean-up operations, ensuring that various contaminants are effectively managed to maintain optimal production efficiency and safety.
The WellStim Series includes iron sulfide scavengers and dispersants designed for the removal of iron sulfide deposits downhole and in surface equipment. Iron sulfide can cause fouling and blockages, leading to reduced efficiency and increased maintenance costs. The WellStim Series offers winterised options, ensuring effective performance even in cold conditions, to keep equipment clean and operational.
By utilising A S Harrison & Co’s scavenger solutions, oil and gas operators can effectively manage and reduce harmful contaminants such as H2S, dissolved oxygen, and iron sulfide. This leads to safer operations, extended equipment life, and improved production efficiency. Whether dealing with gas systems, freshwater, brine systems, or fuel oils, A S Harrison & Co’s scavengers provide reliable and effective solutions for maintaining clean and efficient oilfield operations.
Product and customer insights
CHALLENGE A 40-hectare raw water storage dam had persistent issues with blue-green algae (BGA) blooms, leading to taste and odor problems. Despite the presence of an aeration system to address water stratification and mixing, BGA counts remained seasonally high, particularly in summer and autumn. Upgraded aeration in 2018 did not resolve the issue, leaving the […]
The International Maritime Organisation (IMO) regulation, known as IMO 2020 was the the largest change in regulation relating to marine fuels impacting 75% of the fuel used by the shipping industry.
CHALLENGE A power plant relying on ultrafiltration (UF) and reverse osmosis (RO) faced a critical operational challenge. A wastewater treatment upset severely fouled the UF system, drastically reducing water production. Despite multiple cleaning attempts with sodium hypochlorite and citric acid, transmembrane pressure (TMP) remained high, and flux showed no improvement. The plant’s inability to meet […]
Keeping drilling costs low using Redi-Guard™ High Performance, an ecologically friendly drilling fluid technology with revolutionary rheological and shale encapsulation properties
CHALLENGE A municipal water reuse plant processing 8 million gallons per day (MGD) experienced severe fouling and scaling issues, including calcium phosphate and silica deposits. With steep feed pressure increases and differential pressures in both stages, the plant required frequent cleanings every 4 to 6 weeks, amounting to 32 cleanings annually. Each cleaning cycle resulted […]
The plant was experiencing weekly shutdowns for fiber clean up (~ 3 kg bags of matted slurry is cleaned per week). The shut downs were costly as they reduce plant availability for production.
CHALLENGE A municipal reverse osmosis (RO) plant on Florida’s west coast, with a 20 MGD capacity, faced high operational costs due to its reliance on 93% sulfuric acid for pH adjustment. The plant used a combination of a brackish water reverse osmosis (BWRO) membranes and fiberglass-wrapped membranes across 10 trains, each operating at 75% recovery. […]
CHALLENGE A gold processing plant in New Zealand sought to improve gold recovery efficiency while addressing high Total Organic Carbon (TOC) levels. Elevated TOC increased the Preg-Robbing Factor (PRF), reducing the plant’s ability to efficiently recover gold during the Carbon-In-Leach (CIL) process. The traditional use of kerosene as a carbon blanking agent offered limited efficacy, […]
CHALLENGE A municipal reverse osmosis (RO) plant, with a capacity of 2 million gallons per day (MGD), faced frequent system cleanings, every 2-4 months, due to rising feed pressure. The plant, which sources water from brackish wells and uses Toray TMG-20D-400 membranes in a (16×7) -> (8×7) train configuration, was operating at 78% recovery. Despite […]
Research indicates that Sea Buckthorn may be able to strengthen the immune system. One in vitro study focused on the possible immunomodulatory properties of Sea Buckthorn.
AWC A-110 effectively inhibited scale at a dosage of 3.5 ppm and an operating pH of 6.9. This increase in operating pH reduced the district’s annual acid consumption by ~$350K per year based on their current production.
MCI® -2020 V/O and ChemMaster’s Colorsil were chosen to repair and protect the walls based on their 20 year warranties and the fact that together they could fulfill the other specified repair design requirements.
Despite numerous cleanings, the productivity of the Reverse Osmosis plant would not recover from severe membrane fouling. The membrane autopsy revealed that the ferric hydroxide was seeding
silica polymerization and that even while the ferric hydroxide was removed, the silica scaling was continuing to grow.
The East Hokkaido region is known to have the highest volume of potato product in Japan. Unfortunately, a potato farmer in the area was experiencing a high rate of potato scab infection in his agricultural field.
