Question

I am designing a distillation column which will separate hydrogen sulphide and hydrogen from liquids in a desulphurization of dibenzothiophene. What are the key Health and safety aspects which Are important while doing the retrofit for this process

Answer 1

Distillation column setup for sepsration of hydrogen sulfide (H2S) and hydrogen (H2) gas.

When separating the hydrogen sulfide (H2S) gas, upmost care must be taken towards safety as the gas is highly flammable, shows acute toxicity (health hazards) upon exposure to the respiratory tract. An irritant to skin. It is considered fatal if inhaled. Immediate medical attention is auggested to person(s) exposed to the gas. Proper clothing is to be worn at all times and entire work must be done in a well ventilated area.

When separating hydrogen (H2) gas a highly flammable gas, care must be taken towards safety. Proper clothing must be worn at all times, work must be carried out in well ventilated area. Medical attention is adviced upon severe exposure. It forms explosive mixture when opened to air.
