The present disclosure relates to methods of removing halides from a reactor effluent comprising treating the halide containing carbonylation product with a resin or material comprising a metal ion with a metal loading of greater than 15 wt % are provided herein. In some aspects, the methods involve treating the halide containing carbonylation product with a silver loaded resin which comprises a loading of greater than 15 wt % of silver to remove inorganic or organic halides.

A method of producing treated ion exchange resin material includes exposing an enclosed vessel containing ion exchange resin and a pre-treatment solution to high energy radiation. The treated ion exchange resin material has reduced organic impurities or total organic carbon (TOC).

A system and method for generating water concentrated in calcium bromide from produced water, to provide for drilling fluid having the calcium bromide. The technique includes flowing the produced water through a bed of ion-exchange resin to sorb bromide ions from the produced water onto the ion-exchange resin, and then regenerating the ion-exchange resin to desorb the bromide ions for combination with calcium ions to acquire an aqueous solution with calcium and bromide.
