SOLVENT RECOVERY FROM SWEEP GAS STREAMS

A method for removing solvent from a solvent containing sweep gas stream obtained from a fertilizer coating process is disclosed. The method can include directly contacting the solvent containing sweep gas stream with an aqueous composition comprising 50% wt/wt to 100% wt/wt of water, condensing at least a portion of the solvent out of the solvent containing sweep gas stream into the aqueous composition to produce a solvent-enriched aqueous composition and a recovered sweep gas stream, and removing the recovered sweep gas stream from the solvent-enriched aqueous composition.

20190321795 · 2019-10-24 ·

The present application is directed towards systems for adding components to materials being fluidized in a vibratory mixer by use of atomizers or sprayers. A mechanical system can fluidizes, mix, coat, dry, combine, or segregate materials. The system may comprise a vibratory mixer, mixing vessel containing a first material and a sprayer to introduce a second material. The vibratory mixer may generate a fluidized bed of a first material and the sprayer, coupled to the mixing vessel, may introduce a second material onto the fluidized bed to mix the materials in a uniform and even fashion.

Attrition resistant proppant composite and its composition matters

A hydraulic fracturing and gravel packing proppant composite with protectant on the surface of the proppant and the composition matters of the protectant and proppant. The surface protectant reduces the generation of dust/fines from the proppant caused by abrasion and impingement during transportation and conveyance, particularly pneumatic transfer.

Artificial snow at ambient temperature is used for skiing and is composed of grains of artificial snow at ambient temperature that include magnetic solid grains. The producing method comprises the following steps: (1) using a crushing apparatus to crush a magnetic material into solid grains; (2) using a mesh sieve to sieve the solid grains at a certain particle size; and (3) bonding a layer of material capable of modifying surface property to the surface of the solid grains obtained from sieving. A trail comprises the artificial snow at ambient temperature.

Spray drying

A method of preparing dry core-shell microcapsules from an aqueous dispersion of such capsules, comprising spraying the dispersion through a two-fluid air-liquid nozzle into a heated chamber having an upper part and a lower part, the spraying taking place in the upper part and the lower part being provided with a means of continuous capsule removal. The method allows the drying of capsules with considerably reduced losses.
