Regeneration cycle: switching from HCl to H2SO4




2006

Dear Sir/Madam,

I would like to consult on this area which I have no knowledge on it.

Currently my supplier is switching the from using HCl to H2SO4 for the Regeneration cycle.
The supplier also claim to check on all the equipment parts and do checks on it. But they are unable to provide datas on the sulphate level and other parameters until they have implement the change.

However my company did not measure the sulphate level on the in-coming material. Hence it is also hard to compare the after change sulphate level.

I am not sure whether this change will affect the in-coming material sulphate which in return might affect our company's end product performance.

Hence would you mind to give some feedback on whether is there any difference between HCl or H2SO4 for the Regeneration cycle? Do you have any experience on this type of change before.

Please help by providing your expertise in the case.

Thanks,
Patrick Yew

Not enough information to even guess at an answer.

What is being regenerated? Maybe, ion exchange resin?

What is the product and what specifications must it meet?
