METHOD AND APPARATUS FOR ADSORPTIVE DISTILLATION FOR CRYOGENIC ARGON/OXYGEN SEPARATION

In a method for separating argon by cryogenic distillation, in which a flow containing argon, oxygen and nitrogen and being more rich in argon than the air is sent to a distillation column, and an argon-rich gas flow is withdrawn at the top of the column, a portion of the argon-rich gas flow is mixed with beads to form a gas mixture containing beads, the beads being capable of adsorbing oxygen in the presence of argon at the column operating temperatures; the portion of the argon-rich gas flow mixed with the beads is condensed and then sent to the top of the column; and a bottom liquid containing beads is withdrawn from the column and treated to remove the beads, the beads removed being regenerated to remove the adsorbed oxygen and being again mixed with the argon-rich gas flow.

QUICK RESPONSE, TRANSPORTABLE, STAND-ALONE SYSTEM FOR REMOVING VOLATILE COMPOUNDS FROM CONTAMINATED FLUID STREAMS, AND METHOD OF USE THEREOF

The quick response system and method for removing volatile compounds from contaminated water disclosed herein may comprise, at least, a preconditioning stage, a stripping stage, a condenser stage, a refrigeration stage, and a scrubber stage. The present invention relates to a portable system and method that can be deployed on an emergency or quick response basis to purify aqueous streams containing volatile organic compounds (VOC) and chlorinated hydrocarbons, collectively volatile compounds (VC), emitted from petroleum and chemical processing facilities. The system allows manufacturing facilities having internal cleanup issues to become compliant with environmental standards and guidelines quickly. Once the issue in the petroleum facility are fixed, this method can be demobilized and removed from the site in a short period of time.

APPARATUS, SYSTEMS AND METHODS FOR MANAGEMENT OF RAW WATER AND EMISSIONS UTILIZING HEAT AND/OR PRESSURE ENERGY WITHIN COMBUSTION GAS SOURCES
20210114897 · 2021-04-22 ·

The invention relates to methods, systems and apparatus for distributed management of raw water and internal combustion engine (ICE) gas emissions generated during industrial operations. One aspect of the invention at least partially utilizes a hot gas air knife to increase or partially increase surface area between a raw water and a hot gas in order to vaporize a proportion of the aqueous phase of the raw water and concentrate contaminants within a residual raw water concentrate. The water vapor generated by the vaporization process may be demisted, discharged directly to the atmosphere or alternatively condensed and captured for use. Another aspect relates to how the liquids and gasses interact to continuously flush the surfaces of the system which may help mitigate scaling issues. The invention may help facilitate rapid transfer of ICE combustion gas particulate and ICE combustion gas chemicals onto and into the raw water as it concentrates.
