    Abstract: Disclosed is a low NO x gasification startup system and a method for starting up a low NO x startup system. During startup of a gasification unit, a gasifϊer must be pre-heated via combustion of a fuel source, which thereby generates pollutants. Once pre-heated, the gasifier initially generates off-spec syngas that requires disposal via combustion, thereby generating additional pollutants. The low NO x gasification startup system substantially lowers emission rates of NO x , CO, and/or VOCs during the startup process. During normal operation of the gasification unit, O 2 and CO 2 may be produced, stored, and later used during startup processes. The stored O 2 and CO 2 may be sent to one or more combustion devices and utilized as an oxidant for combusting undesired gases during the startup process. This CO 2 /O 2 mixture provides a higher oxygen content than air and contains substantially less nitrogen than air, thereby substantially reducing NO x formation within the combustion device's emissions.

    Abstract translation: 公开了一种低NOx气化启动系统和启动低NOx启动系统的方法。 在气化装置启动期间，必须通过燃料源的燃烧预热气体发生器，从而产生污染物。 一旦预热，气化炉最初会产生不合格的合成气，需要通过燃烧进行处理，从而产生额外的污染物。 低NOx气化启动系统实质上降低了启动过程中NOx，CO和/或VOC的排放速率。 在气化装置的正常运行期间，O2和CO2可以在启动过程中产生，存储并随后使用。 储存的O2和CO2可以被送到一个或多个燃烧装置，并在启动过程中用作燃烧不需要的气体的氧化剂。 该CO 2 / O 2混合物提供比空气更高的氧含量并且含有比空气少得多的氮，由此显着减少燃烧装置排放物内的NO x形成。

    Abstract: Methods and systems for a gasifier system are provided. The gasifier system includes a gasifier (56) including a syngas cooler (202) configured to transfer heat from a reaction zone of the gasifier to a flow of fluid through the syngas cooler, a reaction vessel (212) coupled in flow communication with the syngas cooler wherein the reaction vessel is adapted to receive the flow of fluid and generate heat in an exothermic shift reaction. The system also includes a heat exchanger (210) coupled in flow communication with the reaction vessel, the heat exchanger adapted to produce relatively high pressure steam using the generated heat.

    Abstract: A sulfuric acid plant includes a wet sulfuric acid (WSA) condenser and a caustic scrubber fluidly coupled to the WSA condenser. The sulfuric acid plant receives an acid gas feed stream and produces a concentrated sulfuric acid stream from the condenser, a sodium bisulfite stream from the scrubber, and a tail gas stream from the scrubber. The acid gas feed stream can be supplied from a gasification facility. The sulfuric acid stream can be used within a desalination facility to neutralize the carbonates within a seawater stream. The sodium bisufite stream can be used hi the desalination facility to dechlorinate the seawater. The tail gas stream includes essentially carbon dioxide and oxygen and is recycled to the gasification facility. Hence, there are no emissions emitted from the sulfuric acid plant. The sulfuric acid plant also includes an incinerator which is fed an oxygen stream and a portion of the tail gas stream.

    Abstract: A desalination and minerals extraction process includes a desalination facility fluidly coupled to a minerals extraction facility. The desalination facility produces at least one desalination tailings stream and a desalinated outlet stream from an inlet feed stream. The minerals extraction facility produces at least one mineral compound and at least one extraction tailings stream from the desalination tailings stream. The extraction tailings stream is recycled into the desalination facility. There are no extraction tailings streams or desalination tailings streams discharged into the environment. The mineral compound includes at least one of boron trioxide, potash, bromine, chlorine, caustic, bleach, soda ash, ammonia chloride, gypsum, and magnesium oxide which can be sold to increase revenue. The efficiency of the process ranges from about seventy to about ninety-five percent. The process can be fluidly coupled to a gasification unit, a cooling tower unit, and a solids removal unit.
