Chemicals Basic Chemicals  Basic Chemicals SIHI Pumps solutions in the field of basic chemicals which include the processing of petrochemicals, basic chemicals, polymers, fertilisers and heat transfer systems. Documents
The vacuum filtration process uses a mechanical system where the suspended mixture that needs to be separated is passed through a filter made of textile or paper tissues.
Vacuum drying uses a thermal process to dry products that have retained moisture Heat is therefore used to bring the liquid in the product up to its boiling point so the liquid vaporises.
Tank farms are often found in chemical plants and the tanks are used to store both the raw materials for the plants various processes as well as storing the finished products.
Most of the cogeneration plants that are producing steam and energy operate using very similar principles.
Steam is produced using feed water in a boiler system that is heated using coal, natural gas, domestic waste or fuel oil. The steam that is generated drives the turbines and generators by converting the kinetic energy into electrical energy.
Membrane technology is ideal for the solvent recovery process due to their high efficiency levels, long service life, where no regeneration is necessary, and their compact design. The recovered substances are neither modified nor contaminated and are suitable for all concentration ranges, and their compact design.
SIHI membrane used for solvent recovery and exhaust gas cleaning.
SIHI membrane used for the separation of chlorinatedhydrocarbons.
SIHI membrane used for recovery of vinyl chloride monomer.
Rectification or counter flow distillation are processes used to separate mixtures made up of multiple components. Rectification is a thermal cutting-off process and is a further development of the distillation process.
SIHI Pumps Asia overview presentation in Bio-Fuel which covers; clear focus on the Bio-Fuel industry, deep application knowledge, creation of new & innovative products, reduction of the pump operating costs (LCC), reduction of your internal costs for new pump installations and how to increase the productivity & reduce downtime of your plants.
Most of the processes in industrial engineering take place where energy is absorbed or released simultaneously. Only a defined temperature level enables the required reactions or working processes to occur. It is an advantage to use heat carrier liquids so that control can be easily managed and maintained in any of these processes.
In this case a heat transfer medium is circulated between the heat source and the consumer of the heat. The working temperature in these heat carrier circuits is generally between 100 °C and 400 °C and different heat carrier liquids are used for the transfer of the energy.
Vaporous solvent emissions degrade slowly in the atmosphere and represent a potential hazard to both the population and the environment. International and local clean air regulations have therefore been passed which impose maximum emission limits.
Distillation is a thermal cutting-off process with the benefit that normally no additional substances such as solvents need to be added. The distillation heating up process separates the fractions out of the liquid.
Chemical reactions are processes where the outcome means new substances are created. This conversion is visible in specific new substance properties. The specific properties of the feed material run off is due to the build properties of the new substance.
Bio Ethanol is made by fermentation of renewable feed stocks, followed by distillation and dehydration processes.
In principle all edible oils and fats – vegetable and animal – can be transformed to bio diesel. For fuel-specific properties, pretreated oils from rape seeds and sunflower seeds are preferred in Europe, but others like soya oil, palm and palm kernel oil, coconut oil, cottonseed oil and animal fats are applicable.
Legal regulations, directives and international standards demand that industry minimises toxic emissions, so as to protect both people and the environment. To reduce toxic emissions the use of absorption technology is often used.
