Bale mover

Self-propelled vehicles for supporting and operating a device are disclosed. Example devices include agricultural devices. The vehicle includes mounting arms that allow the device to be extended forward or rearward of the vehicle. In some embodiments, the device is releasably coupleable to the vehicle. In some embodiments, the vehicle includes rear drive wheels and front caster wheels.

A natural gas liquid plant is retrofitted with a bolt-on unit that includes an absorber that is coupled to an existing demethanizer by refrigeration produced at least in part by compression and expansion of the residue gas, wherein ethane recovery can be increased to at least 99% and propane recovery is at least 99%, and where a lower ethane recovery of 96% is required, the bolt-on unit does not require the absorber, which could be optimum solution for revamping an existing facility. Contemplated configurations are especially advantageous to be used as bolt-on upgrades to existing plants.

Methods and configuration for retrofitting NGL plant for high ethane recovery

A method for removing heavy hydrocarbons from a feed gas by: feeding, into an absorber, a top reflux stream and a second reflux stream below the top reflux stream, wherein the absorber produces an absorber bottom product stream and an absorber overhead product stream; depressurizing and feeding the absorber bottom product stream to a stripper to produce a stripper bottom product stream and a stripper overhead product stream; cooling and feeding a portion of the absorber overhead product stream back to the absorber as the top reflux stream; and pressurizing and feeding the stripper overhead product stream back to the absorber as the second reflux stream. Systems for carrying out the method are also provided.

Integrated heavy hydrocarbon and BTEX removal in LNG liquefaction for lean gases

An apparatus comprises a sensor comprising a left camera and a right camera. A processor is coupled to the sensor. The processor is configured to produce an image and disparity data for the image, and search for a vertical object within the image using the disparity data. The processor is also configured to determine whether the vertical object is a bale of material using the image, and compute an orientation of the bale relative to the sensor using the disparity data. The sensor and processor can be mounted for use on an autonomous bale mover comprising an integral power system, a ground-drive system, a bale loading system, and a bale carrying system.

A LNG liquefaction plant includes a propane recovery unit including an inlet for a feed gas, a first outlet for a LPG, and a second outlet for an ethane-rich feed gas, an ethane recovery unit including an inlet coupled to the second outlet for the ethane-rich feed gas, a first outlet for an ethane liquid, and a second outlet for a methane-rich feed gas, and a LNG liquefaction unit including an inlet coupled to the second outlet for the methane-rich feed gas, a refrigerant to cool the methane-rich feed gas, and an outlet for a LNG. The LNG plant may also include a stripper, an absorber, and a separator configured to separate the feed gas into a stripper liquid and an absorber vapor. The stripper liquid can be converted to an overhead stream used as a reflux stream to the absorber.

Steered caster wheel systems that include a disengagement system to enable a caster wheel steering mode and non-caster wheel steering mode are disclosed. In some embodiments, the caster wheels are mounted to a subframe that may be independently suspended from the chassis of a vehicle such as a self-propelled vehicle.

Steered caster wheel systems

Self-propelled vehicles with extendable devices

Self-propelled vehicles that include swiveling caster wheels and independent drive wheels are disclosed. The self-propelled vehicles are selectively steered in a caster wheel steering mode or a drive wheel steering mode. The vehicle includes a differential system that may include a differential valve that allows hydraulic fluid to be transferred between the left and right drive systems. The differential system may be operable during the caster wheel steering mode such as when the vehicle is driven for transport between sites.

Self-propelled vehicles including a differential system

Self-propelled vehicles that include swiveling caster wheels and independent drive wheels are disclosed. The self-propelled vehicles are selectively steered in a caster wheel steering mode or a drive wheel steering mode. The vehicle includes a steering position sensor to measure the position of the steering system. A control unit varies the rotational speed of first and second drive wheels based at least in part of the signal from the steering position sensor.

A system for processing a gas stream can include an acid gas removal unit comprising a first absorber unit, a compressor, and a second absorber unit. The first absorber unit is configured to receive a feed gas stream containing organic sulfur species and acid gas components, remove at least a portion of the organic sulfur species and acid gas components using a semi-rich solvent at a first pressure, produce a semi-treated gas stream, and produce a rich solvent stream. The compressor unit is configured to compress the semi-treated gas stream from the first pressure to a higher second pressure. The second absorber unit is configured to receive the compressed semi-treated gas stream, remove at least a portion of any organic sulfur species and acid gas components present in the compressed semi-treated gas stream using a lean solvent, produce the semi-rich solvent stream, and produce a treated gas stream.

Two-stage absorption for acid gas and mercaptan removal

Embodiments relate generally to methods and systems for processing a gas stream and for removing mercaptans from a feed stream. A method may comprise compressing a semi-treated gas stream, wherein the semi-treated gas stream comprises organic sulfur species and acid gas components; contacting the semi-treated gas stream with a lean solvent; removing at least a portion of the organic sulfur species and acid gas components from the semi-treated gas stream to produce a treated gas stream and a semi-rich solvent stream; contacting a feed gas stream with the semi-rich solvent, wherein the feed gas stream comprises organic sulfur species and acid gas components; and removing at least a portion of the organic sulfur species and acid gas components from the feed gas stream to produce the semi-treated gas stream based on contacting the semi-rich solvent with the feed gas stream.

A system for reducing SOemissions comprises a hydrogenation reactor, a tail gas cooler, a contact condenser, a hydrolysis reactor, and an absorber. The hydrogenation reactor is configured to receive a Claus tail gas and convert at least a portion of SOin the Claus tail gas to HS to produce a hydrogenated Claus tail gas stream. The hydrolysis reactor is configured to convert at least a portion of COS to HS. The absorber comprises an amine-based solvent and is configured to absorb at least a portion of the HS and recycle the HS to the Claus plant.
