To minimize headspace in a storage container and thereby reduce or eliminate alcohol evaporation, concentrated surfactant solutions stabilized by a diluent of higher volatility than the surfactant, such as alcohol, are stored in a flexible bladder fabricated from fabric including an impermeable or semipermeable membrane, such as polyurethane coated fabric. Because the bladder automatically deflates as the fluid level decreases, minimal head space is maintained and evaporation of the alcohol is thus constrained. A rigid support structure may be employed to hold the flexible bladder. With such a storage system, concentrated surfactant solutions may be manufactured at a convenient location for transport to and storage near an injection well, with considerable time between manufacture and application allowed before the surfactant solution degrades by an unacceptable amount.

For storage of surfactant concentrate solution

A system and process for removing divalent cations from a rich MEG feed stream is presented. An ion exchange bed containing a cation exchange resin adsorbs the divalent cations in the rich MEG feed stream as it flows through the ion exchange bed. After the divalent ions have been removed, the feed stream flows through a flash separator and a distillation column to reclaim MEG. Alternatively, the feed stream flows through a distillation column to regenerate MEG. The spent cation exchange resin may be regenerated in place using a regeneration brine comprised of sodium chloride and water. After use, the regeneration brine may be disposed as waste or recycled to the brine storage tank and re-used to regenerate the cation exchange resin.

Divalent cation removal from rich monoethylene glycol (MEG) feed streams by ion exchange

A system and process for removing hydrocarbons and divalent cations from a rich MEG feed stream is presented. A hydrocarbon removal bed containing a solid adsorbent material adsorbs the hydrocarbons in the rich MEG feed stream as it passes through the hydrocarbon removal bed. After the hydrocarbons have been removed, the rich MEG feed stream flows through an ion exchange bed containing an ion exchange resin in order to remove divalent cations. The rich MEG feed stream then flows through a flash separator and a distillation column to reclaim MEG. Spent solid adsorbent material in the hydrocarbon removal beds and spent ion exchange resin in the ion exchange beds may be regenerated in place using by-products of the MEG reclamation process.

Hydrocarbon and divalent cation removal from rich mono ethylene glycol (MEG) feed streams by regenerable filters

A system and process for removing hydrocarbons from a gas process feed stream is presented. The treatment process may be, but is not limited to, glycol dehydration, amine sweetening, and MEG reclamation. As an example, a hydrocarbon removal bed containing a solid adsorbent material adsorbs the hydrocarbons in a rich MEG feed stream as it passes through the hydrocarbon removal bed. After the hydrocarbons have been removed, the feed stream flows through a flash separator and a distillation column to reclaim MEG. Alternatively, the hydrocarbon removal bed may be used after the MEG reclamation process to remove hydrocarbons in the distilled water from the distillation column. Spent solid adsorbent material may be regenerated in place.
