This disclosure describes methods to separate solids from liquids in a production facility. A process separates components in the process stream by using a mechanical device to separate the solids from the liquids based on a density difference. The process produces the liquids and solids, which may be further processed to create valuable animal feed products.

A system for recovering natural gas liquid from a source, comprising: a heat exchanger for cooling wellstream fluid directed therethrough; a first separator for receiving the fluid from the heat exchanger for separating liquid and gas; in a first configuration, the gas from the first separator being directed to a turbo-expander for reducing the temperature and pressure of the gas to form a cold fluid; the cold fluid being directed to a second separator for separating liquid and gas; gas from the second separator being directed to the heat exchanger where it flows therethrough for cooling the wellstream fluid; wherein if the turbo-expander is not operating, the first configuration may be a changed to a second configuration to bypass the turbo-expander and direct the gas from the second separator to a Joule-Thomson valve to form the cold fluid.

Provided herein are methods and systems for treating a tail gas of a Claus process to remove sulfur-containing compounds. The method includes combusting a tail gas of a Claus process in an excess of oxygen gas to yield a thermal oxidizer effluent. The thermal oxidizer effluent includes sulfur dioxide, water vapor, and oxygen. The effluent is routed to a quench tower and contacted with a dilute aqueous acid quench stream to yield sulfurous acid, hydrated sulfur dioxide, or both. The sulfurous acid or hydrated sulfur dioxide is oxidized with the excess oxygen from the thermal oxidizer effluent to yield sulfuric acid.

The present invention relates to a method for treating a cracked stream stemming from a fluid catalytic cracker unit (FCCU) in order to improve propylene recovery. The present invention also relates to the corresponding installation to implement the method.

To provide a solid-liquid separation system in which a stable operation can be continuously conducted and the introduction cost and the running cost can be suppressed, in cases where moisture or oil are separated from a substance containing moisture or oil by using changes in phase of a working fluid having a nature of dissolving moisture or oil in a liquid phase. Provided is a solid-liquid separation system in which a working fluid that dissolves moisture or oil in a liquid phase is liquefied and brought into contact with a solid substance to thereby allow the working fluid to contain moisture or oil that has been contained in the solid substance, and then the working fluid is vaporized to precipitate the moisture or oil, characterized in that the solid-liquid separation system is provided with a fluid circuit in which a high-temperature-side heat exchanger that vaporizes the working fluid by a refrigerant, a low-temperature-side heat exchanger that liquefies the working fluid by the refrigerant are connected to circulate the working fluid, and a refrigerating cycle in which a compressor, a condenser that exchanges heat with a heat source other than the working fluid, the high-temperature-side heat exchanger, an expansion mechanism, and the low-temperature-side heat exchanger are sequentially connected to circulate the refrigerant, and that the solid-liquid separation system includes a recovery operation mode in which the working fluid in a filling tank is vaporized, besides the solid-liquid separation. For performing the recovery operation mode, a second expansion mechanism is provided between the condenser and the high-temperature-side heat exchanger. The system is also characterized in that the fluid circuit is provided with a heating unit that does not use the refrigerant as a heat source.

Atmospheric water generators, systems and methods are presented involve user authentication, recording and tracking of water volumes dispensed by respective users over periods of various lengths, controlling component noise level and timing, and cleaning, heating and cooling the collected water more efficiently. The generators may be placed in network communication with other such generators to exchange water availability information therewith, or may communicate with a central server element by way of LAN, Internet, cell tower, peer-to-peer mesh or satellite. Information is conveyed to the user regarding the amount of water they consume from the water generators, and their resulting positive impact on the environment. Water dispensing data may be shared on the users' social media accounts, or used as inputs for competitions or games in order to further engage the user. User authentication may be accomplished by way of biometrics or an RFID/NFC tag embedded in the user's water vessel.

A multi-effect system and a multi-effect method for desalination are provided. The method comprises flowing saline water over a thermally conductive plate of a first evaporation chamber; heating the thermally conductive plate to evaporate the saline water, resulting in vapor; removing the vapor from the first evaporation chamber; compressing, using a compressor, the vapor, thereby creating compressed vapor; pumping the compressed vapor into a first condensation chamber; condensing the compressed vapor in the first condensation chamber, resulting in fresh water. The method further comprises heating, by heat released by the condensing of the compressed vapor, a second thermally conductive plate forming a top of the first condensation chamber and a bottom surface of a next evaporation chamber in a next desalination chamber in the vertical stack of desalination chambers.

An apparatus, system, and method for the extraction of water molecules from the air includes a combination of electrical mechanisms and materials engineering. With the help of hydrophobic and hydrophilic materials on an array of thermally conductive and electrically insulated materials, the extraction of water from the air is significantly increased. A combination of hydrophobic and hydrophilic materials and an electric field gradient moves the water molecules towards the collection system thus speeding up the water formation process. This also inhibits the re evaporation of the water droplets.

This invention relates, generally, to the collection of water. More specifically, the invention relates to an atmospheric water generator, to a condensation arrangement for an atmospheric water generator, and to a process for extracting water from air. The generator disclosed herein comprises a coolant chilling unit, a condensation arrangement, and a water holding and/or filtration arrangement which cooperate to extract water from air and store and/or filter the same for use.
