Sulfolane - A Reusable Solvent With Numerous Applications

Private transportation is not a problem today and that is because fuel is cheaper and has gotten easier to produce and extract. Almost every second person around owns a vehicle, even two or three at times and this again is not because he can afford the cars, but rather because he can afford to fuel them. Fuel then becomes one of the main factors behind an individual’s decision to purchase a vehicle. As of today, the prices of fuel and gas witness great shifts, depending on the amount of raw crude oil that is extracted all around the world.

Technically if there was no fuel, cars would run on electricity, but this would never happen since cars were invented to be driven by fuel. Even in the earlier days, running an automobile on petrol proved to be more efficient as compared with running it on steam or coal, not to mention the inconvenience that the latter two provided. Owing to the advancements in technology, today petrol and natural gas are the two primary agents employed in fueling the world.

What makes petrol and natural gas cheap enough to be used by the common people on a daily basis is the process that is used to extract them from their crude form. Without this process, it would be extremely challenging to yield them at such economical prices. Solvents help get the job done easily and in the most economical way possible. Sulfolane is one such solvent that literally drives the refinery business. Sulfolane is used to purify natural gas and petrol, eliminating the impurities and making the agents ready for use. Sulfolane was developed and widely implemented in the Sulfinol Process introduced by Shell in 1964, which removed H2S, CO2 and COS from natural gas making it purer and widely available. The main advantage of using Sulfolane previously and even today is that it is highly effective in purifying or separating aromatic hydrocarbons during liquid-liquid extraction. Having properties that allow it to be miscible in hydrocarbons and water enables Sulfolane to be used to purify a large variety of hydrocarbon based mixtures. Another characteristic that Sulfolane possesses is that it can be used in lower solvent/feed ratios making it cheap, effective and reusable because of its highly stable structure.

Sulfolane appears to be a clear, colorless liquid commonly used in the chemical industry as an extractive distillation solvent or reaction solvent. It is also used as a reaction solvent for the preparation of aromatic sulfonic acids, pyridines, isocyanates and medicines. Having such an efficient and productive solvent will certainly enable most refineries to cut down costs, but that entirely depends on the quality of Sulfolane supplied.

The Billion Dollar Polyethylene

Polymers have been one of the most widely used materials in the industry today. They have been in use because of their customizable properties and flexibility which allows them to be molded into any form or shape and engineered to withstand even the most demanding conditions. Polymers also have a longer lifetime and do not break apart easily when subjected to stress. When polymers are reinforced with multiple fine fibers of glass, they yield fiber-glass which has repeatedly been used for demanding applications in the marine industry.

Today, polymers are used in the manufacture of endless applications. The most widely used application of polymers is in the form of polyethylene or polythene, which people commonly refer to as plastic. Plastics have varied applications across different industries. They are used in the creation of commonly used plastic bags used for packaging and holding goods, and in the form of synthetic polymers to make Bakelite, Neoprene, Nylon and Xylethon. These applications use different forms of polyethylene which serve different purposes in the manufacture of different goods.

Polyethylenes can be classified according to their density. One of the most commonly used types of polyethylene is the Linear Low Density Polyethylene or LLDPE. Although Linear Low Density Polyethylene is very similar to Low Density Polyethylene, its linearity is what makes it different from the latter. This linearity is the result of a different manufacturing process which utilizes lower temperatures and pressures during the copolymerization of ethylene. This results in a more standardized molecular weight distribution, which renders it a linear structure thereby giving LLDPE more tensile strength and enhanced resistance to tear, hence making it a better alternative to Low Density Polyethylene.
In terms of appearance, LLDPE is an off-white solid mainly available in granular form and although it gives out a wax like odor when heated, it is not explosive and does not oxidize.

Linear Low Density Polyethylene is successfully replacing LDPE as a material of choice to work with. LLDPE is thinner and also offers better stress resistance, which is why LLDPE is used to produce plastic bags and sheets (where it offers lower thickness compared with LDPE), plastic wraps, stretch wraps, children’s toys, lids, all types of piping, containers, covering the cables and in flexible tubing. Having such a wide variety of applications has generated a worldwide revenue surpassing billions of dollars.

Sasobit - The Additive For A Cleaner Future

For decades, hot mix asphalt (HMA) had governed road and pavement construction all over the world. Hot mix asphalt was easy to produce but required a high temperature to maintain transportation and application to road surfaces. Hot mix asphalt also takes a longer time to dry up and get the surface ready for use. But the requirement of warmer temperatures often postponed road construction projects until the summer months because the hot mix asphalt just could not set right in the rains or at cooler temperatures. Another disadvantage of hot mix asphalts in road construction was that the higher temperatures required to sustain the mix resulted in consumption of more resources to fuel and sustain the mix before application.

The introduction of warm mix asphalt (WMA), made road and pavement construction a lot more efficient and cleaner. Although both hot mix asphalt and warm mix asphalt consist of the same mixture, it includes the addition of an additive like Sasobit. Sasobit, a bitumen additive, helps in reducing the viscosity of the mixture allowing itto be used at a significantly lower temperature than hot mix asphalt. The addition of Sasobit to the liquid asphalt mix brings down the operating and laying temperature by 50 to a 100 degrees resulting in better flexibility during the laying process making it beneficial for long haul projects. Introducing an additive like Sasobit to the mix reduces the temperature needed to sustain the mixture leading to a lesser amount of fuel which in turn yields fewer emissions compared to hot mix asphalts. This leads to a better working environment with fewer green house emissions being released into the atmosphere, thus making the road pavement construction process more efficient and environment-friendly.

Today more than more than 50 million tons of Sasobit modified asphalt is being used under various climatic conditions. It has been used for demanding applications such as interstate highways, airports including Doha, Frankfurt, as well as in container ports and car race tracks. With so many uses, it is only essential to get the right amount of additive in a timely manner which is why businesses and construction companies in the Middle East and North Africa region prefer Global Trust Enterprises as their trusted supplier.

The Uses Of Morpholine

Morpholine is a colorless, hygroscopic liquid bearing the chemical formula O(CH2CH2)2NH. In appearance, it is colorless, clear and free of suspended matter. It has a characteristic amine odor that is detectable above 0.1 ppm. Morpholine has a maximum water content of 0.3%.
Morpholine is mainly used as an additive in the steam systems of large power plants and refineries. It is often added in parts per million concentrations to adjust the pH levels in water that runs in the steam systems because it behaves exactly like water and also has volatility similar to water. Due to its similar volatility, it breaks up evenly in both water and steam phases which helps prevent corrosion through out the system, keeping the pH level in check.

Globally, Morpholine is also used as an emulsifier to wax fruits. By nature, almost all fruits already have a protective coating on them, but this layer wears off after being cleaned for the packing procedure. Morpholine is added in the form of a wax like substance as morpholine oleate because it dissolves well and hence can be applied evenly as a water-based liquid. Once the layer present on the fruit gets dried, only trace levels of Morpholine will be left behind. Morpholine is used for waxing fruits to help them last longer and remain fresh even during prolonged transit. It also serves as a protective coating to prevent the fruits from getting contaminated by pests and diseases.

Global Trust Enterprises provides its clients with high quality Morpholine and other organic and inorganic solvents at the most competitive prices. Its large and extended global network enables GTE to source products quickly and make just in time deliveries.

Earth Moving Equipment, How It All Began

Earth moving equipment today is being utilized in a lot of applications all over the world, from mining to construction to agriculture, and even military applications. Ever wondered how such equipment came into use and why are they used on a large scale all over the world today?

Initially before the industrial revolution companies and businesses were local and small scale which did not require a lot of man power to build them. Moreover labor was cheap (still is in certain developing countries) which is why land owners used them for their farms and smaller building projects. With the onset of the industrial revolution there was a sudden boom of large projects which required enormous amounts of man power and even the largest amount of man power was not enough which led to the slow down of most large scale projects leading to delays and increased costs for hiring laborers. With the inventions of vehicles, transportation became much easier but the shoveling and digging needed increased amounts of workers that needed to work tirelessly. Increased amount of laborers easily translated into reduced profits for development companies. Gradually, construction machines were invented which brought down the time taken to build large projects and facilities. Such equipment seemed to deliver a much better output and a lot of contractors and tradesmen soon realized their value of getting more work done in a minimal amount of time and with reduced costs.

Today earth moving equipment offers a wide variety of choices to contractors who completely rely on the smooth functioning of such equipment for their building and construction plans. The bulldozer is one of the most widely used types of earth moving equipment today for moving material, with it being available from small ones which are used for backyard shoveling for local earth moving purposes to  the massive and extremely powerful ones that are used on mining projects. The technology that goes into new age bull dozers is also very complex requiring them to have trained servicemen and operators. The most commonly used type of earth moving equipment is the excavator which is used for digging and delivering material onto dumper trucks. They consist of a boom and a bucket and are available in a large variety of sizes from the mini-excavator which weighs about 3,549 pounds, to the largest excavator used in mining which is in excess of 2,160,510 pounds. Such excavators have a heavy capacity which makes them more productive and help increase profits.

But in the end it all boils down to having the right suppliers to getting the best equipment to get your work done. This requires expertise and commitment that only Global Trust Enterprises a general trading company in Dubai can deliver. Global Trust Enterprises delivers various types of equipment and spares to its customers in the Middle East and North Region, including heavy earth moving equipment from world renowned brands such as Caterpillar, Hitachi, Kubota and Hyundai.

An Insight Into The Production And Refinement Of Aluminum

Also known as one of the most widely recycled metals on earth, aluminum is naturally occurring, although in mineral form in bauxite ores. These ores need to be processed and unlike most other metals, it is rather difficult to extract aluminum from bauxite ores because of the amount of energy required for the same. Today bauxite ores are converted to aluminum through the Hall-Heroult process of electrolysis, which results in a 99% pure aluminum metal. Better purification of aluminum can be obtained via the Hoope process which gives a more pure form of aluminum at 99.99%.

The process of electrolysis requires an enormous amount of electricity which is why most aluminum smelters are usually located near power stations. Hence it is not surprising to know that aluminum production takes place in countries where electricity is cheaper. Although there are sufficient reserves of aluminum available here on earth for future generations, it is still easier for companies to recycle existing aluminum and save on electricity costs thereby reducing the cost of the raw material itself. Recycling aluminum barely consumes 5 percent of the energy needed to produce similar virgin aluminum through the process of mining. Recycling aluminum from scrap and old parts not only makes it cheaper to obtain raw aluminum but also reduces the damage done to the environment.  

With both mining and recycling production processes set in place the applications for aluminum usage have vastly increased due to its now reduced price. Reduced prices along with aluminum’s already excellent ductility and malleability have found new applications in multiple industries. These multiple applications found their way in the form of aluminum being mixed with other metals such as copper, manganese and zinc to form alloys of aluminum. Aluminum is today used in everything from electronic devices to cars to airplanes and even rockets.

Hydraulic Vs Non-hydraulic Cement

Cement is technically a binder a chemical substance made to either hold itself to take up a form or to hold two other objects together. With an existence that traces back to the Romans, it initially consisted of a mixture of crushed rock and lime which was used as the binding substance in construction. Today, the most commonly used form of cement worldwide is Portland cement which is purpose built for the field of construction. Cement can be broadly classified into non-hydraulic cement and hydraulic cement.

Non-hydraulic cement is a basic and cheaper alternative compared to hydraulic cement. Non-hydraulic cement was the initial mixture of the original cement that was discovered centuries ago. As opposed to hydraulic cement, it does not harden when exposed to water after the cement has been set after use. What makes it a bad contender against hydraulic cement is that it takes a substantially longer time to dry off and gain strength after being set. Even in use for bricklaying in mortar, non-hydraulic cement takes a very long time to gain strength.

Due to many problems and issues faced with long drying periods along with a requirement for dry weather conditions, non-hydraulic cement proved to be a failure which lead to the development of hydraulic cement.

Hydraulic cement unlike non-hydraulic cement did not require a substantial amount of time to dry. Unlike hydraulic cement, it did not demand for the right weather conditions and dried in almost any weather. Today with various improvements in science and with new chemicals being developed, hydraulic cements have reached new heights and many more applications. Stucco mixed with hydraulic cement is now being used for finishing brick buildings in wet weather conditions. Their ability to harden lies in the process called hydration in which chemical reactions take place in the mixture without any specific requirement for the water content which is why such cements can even be set underwater.
