Floating liquefied natural gas pretreatment system
A pretreatment system and method for a floating liquid natural gas (“FLNG”) facility are presented. The inlet natural gas stream flows through a membrane system to remove carbon dioxide and a heat exchanger, producing first and second cooled CO2-depleted non-permeate streams. The first cooled CO2-depleted non-permeate stream is routed to additional pretreatment equipment, while the second cooled CO2-depleted non-permeate stream is routed directly to a LNG train. Alternatively, the inlet natural gas stream may flow through a membrane system to produce a single cooled CO2-depleted non-permeate stream that is routed to the LNG train after sweetening and dehydration. Because the pretreatment system delivers the incoming gas stream to the LNG train at a lower temperature than conventional systems, less energy is needed to convert the gas stream to LNG. In addition, the pretreatment system has a smaller footprint than conventional pretreatment systems. |

This invention relates to production of an aqueous solution containing ammonium thiosulfate from a feed gas containing hydrogen sulfide (H2S) and ammonia (NH3). Sufficient separation of feed gas H2S from NH3 is achieved by controlling individual NH3 and H2S absorption mass-transfer rates in a single co-current stage, whereby a first gas contacts a first liquid containing ammonium bisulfite (ABS).

The second gas stream is oxidized to sulfur dioxide (SO2) comprising a third gas stream. The third gas stream contacts the second aqueous stream in a second contact stage whereby DAS in the second liquid stream is converted to ABS and returned to the first contacting zone. |

A system and method are provided for continuous monitoring and controlling of aircraft braking that can reduce brake wear and aircraft operating costs through the retention of carbon brake powder from the brakes or addition of carbon powder in a device mounted with respect to the brake disc stack. The use of carbon powder reduces brake wear by providing small particles between the brake discs, acting as a buffer between the brake discs when the brake stack is clamped together. Moreover, when carbon powder or small particles are used at application, such use reduces the roughness of the carbon surface and reduces the number of large particles from braking off the carbon surface, thereby reducing brake wear. Adaptive or selective braking may be used in conjunction with carbon powder to further reduce carbon brake wear. |
