Scale Cleaning chemical for cleaning of boilers/heat exchangers are to prevent tube failures and improve unit availability. Tube failures in low-pressure boilers/heat exchangers are normally the results of creep which occurs when internal deposits produce excessive metal temperature. A relatively smaller quantity of deposit creates difficulties in high-pressure boilers. After a boiler/heat exchanger placed into service, numerous solid constituents may enter the units with the feed water &…

Read moreThe Asia Petrochemical Industry Conference (APIC) is an annual, international conference within the petrochemical industry intended to "spur mutual friendship and goodwill" within the industry with an aim to encouraging its "sound development". Known at its 1979 founding as the East Asia Petrochemical Industry Conference, it was a combined project of industry associations within Japan, Korea, and Taiwan, which northern Asian nations alternated hosting duties. In 2000, the conference was…
Read moreGypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O. It is widely mined and is used as a fertilizer, and as the main constituent in many forms of plaster, blackboard chalk and wallboard. A massive fine-grained white or a lightly tinted variety of gypsum, called alabaster, has been used for a sculpture by many cultures including Ancient Egypt, Mesopotamia, Ancient Rome, the Byzantine Empire and the Nottingham alabasters of Medieval England.
Read moreDiethylene glycol (DEG) is an organic compound with the formula (HOCH2CH2)2O. It is a colorless, practically odorless, poisonous, and hygroscopic liquid with a sweetish taste. It is miscible in water, alcohol, ether, acetone, and ethylene glycol. DEG is a widely used solvent. It can be a contaminant in consumer products; this has resulted in numerous epidemics of poisoning since the early 20th century.
Read moreDuring the past century, astronomy has been revolutionized by the use of new methods for observing the universe. Astronomical observations were originally made using visible light. Galileo Galilei pioneered the use of telescopes to enhance these observations. However, visible light is only a small portion of the electromagnetic spectrum, and not all objects in the distant universe shine strongly in this particular band. More useful information may be found, for example, in radio wavelengths.
Read moreBOILER COAGULANT is a liquid sludge conditioner designed to prevent the formation deposits in boilers. Boiler Water sludge is caused by the presence of small quantities of hardness salts and traces of suspended matter in operational steam boilers and feed waters.This sludge settles on the surface forming a hard scale which indirectly increases the maintenance costs, degrades the heat transfer efficiency and overall boiler efficency. Therefore in order to ensure the boiler system and…
Read moreSodium chromate is the inorganic compound with the formula Na2CrO4. It exists as a yellow hygroscopic solid, which can form tetra-, hexa-, and decahydrates. It is an intermediate in the extraction of chromium from its ores. Sodium chromate, like other hexavalent chromium compounds, is toxic and carcinogenic. t is obtained on a vast scale by roasting chromium ores in air in the presence of sodium carbonate:
