The Plant has 3 trains of rated production capacity of 30 metric tons per day of HCL (as 100%) with the 330 on stream day per year. Dry Cl2 gas is supplied from compressor , 10-15% excess H2 gas also compressed and both Cl2 and H2 gases are charged to combustion chamber. Reacted HCl gas then cooled and charged to absorber with absorbing dilute HCL solution then conc. HCl solution falls down to HCl reciever by gravity
