The present invention provides a covalent-organic framework (COF) body, populations of such bodies, a method for manufacturing a covalent-organic framework (COF) body, and (a) a gas storage system or a gas separation system comprising a gas storage vessel and a population of such COF bodies. The COF body comprises a plurality of primary COF particles, some or all of the primary COF particles being agglomerated as COF agglomerates. The average diameter of the primary COF particles is between nm and 120 nm, and the average diameter of the agglomerates is larger than the average diameter of the primary COF particles and between 15 nm and 250 nm. By careful control over particle size distribution during the formation of the COF material, it is possible (b) to form COF materials into high bulk density shapes and forms which are industrially useful and practical without losing sorbent performance.

METHODS AND SYSTEMS FOR REDUCING THE CONCENTRATION OF AMINE IN WASH LIQUID USED IN INDUSTRIAL PROCESSING

A method for reducing the concentration of amines in a wash liquid stream exiting a wash section in an acid gas scrubbing process includes introducing the wash liquid stream exiting the wash section of the acid gas scrubbing process to an adsorbent material, wherein the wash liquid stream has a first concentration of amines. The wash liquid stream having the first concentration of amines is flowed through the adsorbent material, and the adsorbent material retains at least a portion of the amines thereby providing a wash liquid stream having a second, reduced concentration of amines. The wash stream with reduced concentration of amines is recycled back to the wash section to remove amines more effectively from the acid gas being scrubbed. The adsorbent material can be regenerated for reuse. Amine recovered from the regenerated adsorbent material can be recycled to the process for reuse.

Beads of materials such as activated alumina, zeolite and silica gel, are used as chloride salt absorbers. The beads are mixed with high-salt gypsum. After mixing for a short time, the mixtures are dried, and the beads and the powder are separated by using a sieve or other physical separation device resulting in a low-salt gypsum which can be used as a gypsum source to make gypsum wallboard.

Systems and methods for gas treatment

A system and process for the recovery of at least one halogenated hydrocarbon from a gas stream. The recovery includes adsorption by exposing the gas stream to an adsorbent with a lattice structure having pore diameters with an average pore opening of between about 5 and about 50 angstroms. The adsorbent is then regenerated by exposing the adsorbent to a purge gas under conditions which efficiently desorb the at least one adsorbed halogenated hydrocarbon from the adsorbent. The at least one halogenated hydrocarbon (and impurities or reaction products) can be condensed from the purge gas and subjected to fractional distillation to provide a recovered halogenated hydrocarbon.
