[5] Sasol Gulf – Operation Manual 4068 Words 17 Pages. } catch(e) {}. In the furnace, the sulphur is fed through a pipe and falls on a surface of refractory balls, while the combustion air is supplied in counter current, thus obtaining the complete combustion of sulphur without its spraying through a nozzle; which might often clog owing to sulphur impurities. 1k Views. The cooling water at the head of sulfonation reactor can go back with pressure, which can go directly to the cooling water system of the sulfonation plant. LABSA Production Process Modification 2. Production of Linear Alkyl Benzene Sulphonic Acid (LABSA). LAS are then neutralized to the desired salt (sodium, ammonium, calcium, potassium, and triethanolamine salts). [6] Fig 11 – SO2 / SO3 Production. After finding the color Klett, the sample of the product is then titrated with ethanol, drop by drop after adding the indicator. •Add 25ml of ethanol and mix well to ensure the sample is dissolved completely. This is used to stabilize the sulphonated DDB. Fig 20 – Flexi Bags within cardboard perimeter. A sample of the product is taken This means that the air is dry as if the air was cooled down to -40 degrees Celsius. •Blue Filter No. Huge amount of reaction materials inversely flow back to the reaction inlet and join the neutralization reaction. Gas Scrubbing / Exhaust Gas Treatment Particles larger than the cut point will be removed with a greater efficiency and smaller particles with a lower efficiency. The moisture entrained in the vaporized vapor is send back to the vapor-liquid separator. •Sulphur Melting – Ignition of sulphur (S) to sulphur dioxide (SO2) •SO3 Production – Oxidation of sulphur dioxide to sulphur trioxide (SO3) using catalyst vanadium pentoxide (V2O5) under optimum temperature. Import quality Labsa supplied by experienced manufacturers at Global Sources. They expertly meet all your unique requirements. ➢The gas temperature is of course too high to be suitable for sulphonation; therefore some heat exchangers in the series are used to cool the gas down to proper sulphonation temperature. Other sulfonation alternative reagents are sulfuric acid, diluted sulfur trioxide, chlorosulfonic acid and sulfamic acid on falling film reactors. Fig 18– Electrostatic Precipitator Functionality Details, Fig 19 – Electro Static Precipitator Construction Details. More than 80% of LAS produced worldwide is used in detergent production. •Low cost surfactant for detergents Sulphur Dioxide & Sulphur Trioxide Production. The sulphur combustion furnace has been designed for this special purpose. The speed used for organics delivery is provided by stainless steel cam rotor pump which is controlled by frequency converter. Required fields are marked *, © 2021 by bring the pixel. Hits: (LINEAR ALKYLBENZENE SULFONIC ACID (LABSA [vc_row][vc_column][vc_column_text] Linear Alkyl Benzene Sulfonic Acid Sulfonic Acid Alternatively, ethylene can be oligomerized (partially polymerized) to produce linear alkenes. •Cost effective, anionic surfactant. In practice two cylinders with silica-gel are used; one for drying the air, the other is reconditioned. These labsa manufacturing plant solutions majorly come in slow-release type as well as in different pack sizes to suit your requirements. Every two hours, regular analysis of the product is carried out to make sure the quality of the product is maintained. try { [2] www.sasol.com In order to allow quick startup, a preheating system has been provided. With the increase of number of the tubes, this advantage is more obvious. A checking about the effective regeneration is made by verifying the Silica gel indicator through the sight glasses, as well as by verifying the outlet temp., of the regeneration air on the recording thermometer. Process Involved In the Manufacture of LABSA Fig 3 – Flowchart of the process behind the production of LABSA. The properties of LAS differ in physical and chemical properties according to the alkyl chain length, resulting in formulations for various applications. Linear alkyl benzene sulfonic acid mainly use is for manufacturing household detergents containing washing powders and liquids, dishwashing liquids and many other detergents. Fig – 2 Progress of Reaction against Energy •Phenolphthalein Huge amounts of sulfur are produced from the desulphurization process and sold to the chemical plants. Larger (denser) particles in the rotating air stream have too much inertia to follow the tight curve of the air stream and strike the outside wall, falling then to the bottom of the cyclone where they can be removed. This is reached by preheating with hot air and the upper part of the catalyst tower is heated upto a temperature of 400-420 degree Celsius. This system is quite simple; it does not require any maintenance and the gas composition does not change. if ( localStorage.getItem(skinItemId ) ) { : Molecular Formula: R-C6H4SO 3H R=C 12-14 alkyl Characteristics: 1, One of main raw material of detergent. Afterwards it is transferred with the help of a pump to the neutralization unit. The sulphonic acid is corrosive in nature and therefore requires a vehicle with a pre-fitted tanker. The standard value for Klett is around 50%(maximum). The cyclone geometry, together with air flow rate, defines the cut point of the cyclone. To prevail over the fouling and cleaning problems, larger tube At the time of loading the forklift will carry these drums to a loading station with an adjustable ramp. •Improve plant production quality MASS DENSITY AT 20 DEGREES C : ~ 1.070 g/cm3 VISCOSITY AT 20 DEGREES C : ~ 1500 – 2000 mPa.s. The raw material to be sulphonated is fed in co-current with the gas. Therefore a temperature of 140 is maintained to prevent wastage of sulphur due to the above mentioned causes. In a conical system, as the rotating air-flow moves towards the narrow end of the cyclone the rotational radius of the air stream is reduced, separating smaller and smaller particles from the stream. FREE OIL1.5% max Through this, the amount of ethanol required to reach the n point is noted and the acid level of the product is calculated. Linear alkylbenzene sulfonic acid is the largest-volume synthetic surfactant because of its relatively low cost, good performance, the fact that it can be dried to a stable powder and the biodegradable environmental friendliness as it has straight chain. •Gas Separation & Gas Scrubbing – Separation of LABSA from unreacted gases. LAB is also required for the manufacturing of LABSA and linear alkylbenzene sulfonate (LAS), which •Fill 40mm path length cell (clean and dry) with mixture and other cell as reference cell. •Good Surface active properties •Free Acid % = ( T1 x Molarity of NaOH x titrated acid molecular weight ) [10]. The labsa manufacturing plant solutions also come in distinct variants such as powder, granules, and flakes. A Klett colorimeter allows light to pass through and determines the colour Klett of the substance. LABSA: Linear Alkyl Benzene Sulfonic Acid, is commonly used in manufacturing household detergents that include laundry powders, laundry liquids, dishwashing liquids, and other household cleaners. •10ml Burette The residual unconverted SO2 is absorbed in the scrubbing column in which a water and caustic soda solution is continuously recycled. 2. [9] www.chemicalland21.com Deionized process water controlled by mass flow meter. oAbility to easily stock spare parts cost Sometimes the wall thickness is determined by the maximum pressure differential across the wall. An accurate amount of ether sulfate ester is adjusted by a mass flow meter, and then enters into the continuous neutralization reaction pump inlet. _g1 = document.getElementById('g1-logo-mobile-inverted-source'); The organic feed of each tube is controlled by high-precision rotameter, with 1.5% control accuracy regardless of the changes of tube numbers. The sulfonation reagents include sulfuric acid, chlorosulfonic acid, sulfamic acid and diluted sulfur trioxide. There are two processes for the manufacture of acid slurry – continuous and batch. •Prepare solvent of ethanol 99.99%, methanol, propan-2-ol or distilled water or a mix of all. This should be avoided as it can cause blockage. It is mainly used to produce household detergents such as washing powder, detergent of dishware, detergent of light or hard dirt, cleaner of textile industry, dyeing assistant, degreaser of plating A hose is connected to the valve and to the flexi-bag.
