Falling Film Evaporator

Номер: US20120129242A1
Автор: Charles David Gilliam, Stefanie Renee Gilliam
Принадлежит: Individual

An apparatus and method are disclosed for controlling the thickness of a flowing, laminar fluid film. The film flow may be gravity-induced or the result of an alternative force. The fluid is deposited on an upper end of a flow surface where a relatively thick layer of the film forms. The film flows over a fluid dispersal region where the surface area is rapidly expanding, which results in rapid thinning of the film thickness. The fluid then flows over an active region where the surface area is designed to control the fluid film thickness. For example, in some applications, it may be desirable to maintain an approximately constant film thickness as the fluid flows over the active region of the surface. The geometry of the flow surface is used to obtain the desired control over the fluid film thickness. The flow surface is the outer surface of a solid with a closed upper end and a lower end that may be open or closed. An open lower end allows for injection of a heated material, which may be used to heat the solid surface. This process may be used to heat the fluid flow surface so that evaporation of the flowing fluid results. A falling film evaporator is one application of the disclosed invention. A carbon capture system using a thin, flowing algae film is another application. Other potential uses of the invention are disclosed as well.

Method for recycling deoiled water using counterflow falling-film evaporators

Номер: US20120145386A1
Автор: Chandrakant Tiwari, Daniel P. Bjorklund, David Kersey, Gregory J. Mandigo
Принадлежит: Aquatech International Corp

We provide an evaporator technology for treatment of produced water that may be deoiled water. Systems described herein utilize a vertical tube heat exchanger bundle where the brine is distributed in a falling film along the inside of the tube wall. Condensing steam causes a portion of the deoiled water to evaporate; this water vapor travels upward in a counterflow direction relative to the deoiled water. This evaporator technology provides several design advantages over the conventional vertical tube co-current flow evaporators (where the vapor flows downward with the falling film). These advantages include a minimal total installed cost (TIC) as well as offering optimal design features for water chemistry management.

ANTISOLVENT PROCESS FOR TREATING LIQUIDS THAT INCLUDE HIGH TOTAL DISSOLVED SOLIDS

Номер: US20130140234A1
Автор: Drake Ronald N.
Принадлежит:

The present invention provides a low energy alternative to conventional thermal/evaporation processes for “zero liquid discharge” treatment of strong saline brines. The products of the process include a salt-free liquid and solid salt. In particular, an antisolvent can be mixed with liquids containing high total dissolved solids. The mixture can be chilled, whereby solid salt is precipitated and separated from the mixture at near ambient temperature leaving a mixed liquor. The antisolvent can be selected from a class of organic compounds that form solutions with salt brines that exhibit a critical solution temperature lower than a critical solution temperature of the salt brines alone.

A humidification-dehumidification apparatus featuring enhanced heat recovery includes a shared interior wall extending along a vertical axis and defining and separating humidifying and dehumidifying chambers. Heat-transfer members extend through the shared interior wall and across a majority of each chamber, while a spray device is configured to direct a spray of liquid feed composition onto the heat-transfer members inside the humidifying chamber. The liquid feed collects on the heat-transfer members in the humidifying chamber, and water evaporates from the liquid feed on the heat-transfer members, leaving a concentrated remainder of the liquid feed in liquid form. Carrier gas passes through the humidifying chamber where evaporated water is entrained in the carrier gas to form a moist carrier gas that passes from the humidifying chamber to the dehumidifying chamber, where the water vapor condenses from the moist carrier gas on the heat-transfer members.

Disclosed herein are processes for recovering paraxylene in which a first simulated moving bed adsorption unit is used to produce a paraxylene-rich extract stream that also contains a significant amount of the ethylbenzene and a paraxylene-depleted raffinate stream. Because a significant amount of the ethylbenzene is removed in the paraxylene-rich extract stream (at least enough to limit buildup in the isomerization loop), the paraxylene-depleted raffinate stream may be isomerized in the liquid phase. Avoiding vapor phase isomerization saves energy and capital, as liquid phase isomerization requires less energy and capital than the vapor phase isomerization process due to the requirement of vaporizing the paraxylene-depleted stream and the use of hydrogen, which requires an energy- and capital-intensive hydrogen recycle loop. 1.
