Methods and systems for converting ammonium waste streams into certifiably Organic ammonium salts having a variety of uses in greenhouse gas-reducing activities are herein described. The resulting ammonium salt compositions can be used to enhance crop yield.

A multi-pass contact tray for use in a mass transfer column has a mixture of fixed valves to movable valves, with the numbers of the respective valves being selected to balance the volumetric flow of vapor through deck segments when the vapor is ascending at volumetric flow rates insufficient to maintain the movable valves in an open position.

A method of separating a feed stream in a distillation tower. Vapor is permitted to rise upwardly from a distillation section of the distillation tower. A feed stream is introduced into a controlled freeze zone section of the distillation tower, the controlled freeze zone section being situated above the distillation section. The feed stream is released above a level of a liquid retained by a melt tray assembly in the controlled freeze zone section. Vapor from the distillation section is directed into the liquid retained by the melt tray assembly. A solid is formed from the feed stream in the controlled freeze zone section.

A multi-stage bubble-column vapor mixture condenser includes at least a first stage and a second stage. Each stage includes a condenser chamber including a carrier-gas inlet and a carrier-gas outlet and contains a condensing bath. Carrier gas bubbles from the carrier-gas inlet up through the condensing bath, overcoming a hydrostatic head of the condensing bath, to a volume of carrier gas above the condensing bath. The carrier-gas outlet is positioned with an opening for carrier-gas extraction, and the first-stage carrier-gas outlet is in fluid communication with the second-stage carrier-gas inlet to facilitate flow of the carrier gas through the condensing bath in the first-stage condenser chamber, into the volume of carrier gas above the first-stage condensing bath, and then through the condensing bath in the second-stage condenser chamber. The first-stage condenser chamber further includes an intermediate-exchange inlet positioned and configured to inject additional carrier gas into the first-stage condenser.

The present disclosure relates to a valve tray for use in a chemical process column. The valve tray includes a plurality of apertures formed therein. A plurality of valves are maintained in a spaced relationship relative to individual apertures of the plurality of apertures. An area of the individual apertures is less than an area of individual valves of the plurality of valves.

Disclosed is a vapor splitter including: a chimney tray dividing an internal space of a housing into an upper space and a lower space; a chimney provided on the chimney tray to enable the upper space and the lower space to communicate with each other; a cap covering the chimney with a gap therebetween such that a gas discharge hole is formed so that gas, coming out through the chimney, can be transferred to the upper space through the gas discharge hole; a liquid feeding unit for feeding liquid to the upper space; and a liquid discharging unit for discharging the liquid out of the upper space. The size of the gas discharge hole is adjusted by controlling the height of the liquid collected on the chimney. Further disclosed is a method of adjusting a vapor split ratio using the vapor splitter.

A multi-stage bubble-column vapor mixture condenser comprises at least a first stage and a second stage. Each stage includes a carrier-gas inlet and a carrier-gas outlet, as well as a condenser chamber containing a condensing bath in fluid communication with the carrier-gas inlet and the carrier-gas outlet. The carrier-gas inlet is positioned to bubble carrier gas from the carrier-gas inlet up through the condensing bath, overcoming a hydrostatic head of the condensing bath. The carrier-gas outlet is positioned with an opening for carrier-gas extraction above the condensing bath, wherein the first-stage carrier-gas outlet is in fluid communication with the carrier-gas inlet of the second stage to facilitate flow of the carrier gas through the condensing bath in the condenser chamber of the first stage and then through the condensing bath in the condenser chamber of the second stage.

A distillation column and tray assembly is disclosed herein. The distillation column includes a removable inner tray assembly with adjustable downcomer tubes. The removable tray assembly enables the user to selectively change distillation plates when so removed. When removed, a distiller or brewer may adjust the downcomer tubes to change the fluid level on the distillation plates, or bypass certain distillation plates completely. Certain embodiments of the invention include a feature of an O-ring recessed around a perimeter of the plates permitting a tight seal and reducing manufacturing costs.
