Safety Aspects in sulphuric acid

Sulphuric acid
Safety Aspects in plant


Sulphuric acid is highly corrosive liquid and it is very dangerous when it is improperly handled. When it is stored in tanks or drums, hydrogen may generate inside them and it may form dangerous air – hydrogen explosive mixture. As such no open lights or sparks and smoking should be permitted near the container of sulphuric acid.

Salphuric acid
SALPHURIC ACID


 sulphuric acid , also known as vitriol, is a mineral acid composed of the elements sulphur, oxygen and hydrogen, with molecular formula H2SO4. It is a colorless, odorless, and syrupy liquid that is soluble in water and is synthesized in reactions that are highly exothermic.

SALPHURIC ACID APPLICATION  :-


(1) Sulphuric acid is also a key substance in the chemical industry.
(2)  It is most commonly used in fertilizer manufacture,
(3) but is also important in mineral processing, oil refining, wastewater processing, and chemical synthesis.
(4) It has a wide range of end applications including in domestic acidic drain cleaners,[
(5) as an electrolyte in lead-acid batteries, and in various cleaning agents.

Gsfc urea plant

    UREA PLANT PROCESS AT G.S.F.C. LTD INTRODUCTION => Urea was first synthetically in 1828 by wobler from ammonia and cyanuric acid and urea became the first organic compound prepared by synthesis from inorganic material. => The present method of synthesizing urea from NH3 & CO2 has been known in principle since 1968 but commercial production by this method started in 1922 in Germany & in 1932 in United state. => In India, at present there are about 28 urea plants having annual capacity of 21 million ton of urea.  PROPERTIES OF UREA 1.
