A S Harrison & Co is a prominent supplier of raw grease additives essential for the lubrication industry. Their product line includes Aluminium Complex Reagent, Lithium Hydroxide, Calcium Sulfonates, and various Specialty Base Oils & Thickeners, each contributing unique properties to grease formulations.
Aluminium Complex Reagent: This additive is crucial for producing high-performance, multi-purpose greases. Aluminium complex greases are known for their excellent water resistance, thermal stability, and mechanical stability. These greases can operate under high temperatures and heavy loads, making them ideal for industrial applications.
Lithium Hydroxide: Lithium hydroxide is a key component in the production of lithium-based greases, the most common type of lubricating greases. Lithium greases are highly valued for their superior performance in terms of temperature stability, water resistance, and oxidation stability. They offer excellent lubrication properties, making them suitable for automotive, industrial, and marine applications.
Calcium Sulfonates: Calcium sulfonates are used as thickening agents in grease formulations. They provide exceptional rust and corrosion protection, high dropping points, and enhanced load-carrying capabilities. These greases are particularly useful in environments exposed to saltwater or other corrosive conditions, making them ideal for marine and heavy-duty industrial applications.
Specialty Base Oils & Thickeners: Specialty base oils and thickeners are fundamental components that determine the viscosity, consistency, and overall performance of the grease. A S Harrison & Co offers a range of specialty base oils, including synthetic and semi-synthetic options, tailored to meet specific application requirements. Thickeners, such as polyurea and clay, are selected based on the desired properties of the final product, including temperature stability, mechanical stability, and compatibility with other additives.
A S Harrison & Co’s raw grease additives play a vital role in formulating high-quality lubricants that meet the demanding requirements of various industrial sectors. Their comprehensive range of additives ensures that their customers can produce greases with superior performance, durability, and reliability.
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.
