A multifunctional ship for the collection and recycling of ocean debris and the system thereof may include a hull; a detection device provided on the hull to detect ocean debris floating on the sea or deposited on the seabed; a collection device installed on the hull to collect the ocean debris detected by the detection device; a sorting device installed on the hull to sort the ocean debris collected by the collection device; a compressing device installed on the hull to compress the sorted ocean debris to compress and remove moisture and reduce the volume; a waste plastic recycling device installed on the hull to produce recycled oil by thermally decomposing the waste plastic compressed in the compressing device; a storage tank installed at the bottom of the hull to store the recycled oil produced; and a purifier for purifying wastewater generated in the process of producing recycled oil.

In an aspect, a system includes a mixer configured to mix a fuel stream with a solvent to form a mixed stream, the solvent having a higher affinity for a second component of the fuel stream than for a first component of the fuel stream. The system includes a first separator configured to separate the mixed stream into (i) a first fuel fraction including the first component of the fuel stream and (ii) a mixed fraction including the second component of the fuel stream based on a difference in volatility of the first fuel fraction and the mixed fraction. The system includes a second separator configured to separate the mixed fraction into a second fuel fraction including the second component of the fuel stream and a solvent fraction.

Embodiments of the present invention are generally related to a system and method to remove hydrogen sulfide from sour water and sour oil. Particularly, hydrogen sulfide is removed from sour water and sour oil without the need for special chemicals, such as catalyst chemicals, scavenger chemicals, hydrocarbon sources, or a large-scale facility. The system and method in the present invention is particularly useful in exploratory oil and gas fields, where large facilities to remove hydrogen sulfide may be inaccessible. The present invention addresses the need for safe and cost-effective transport of the deadly neurotoxin. Particular embodiments involve a system and method that can be executed both on a small and large scale to sweeten sour water and sour oil.

Biomass processing devices, systems and methods used to convert biomass to, for example, liquid hydrocarbons, renewable chemicals, and/or composites are described. The biomass processing system can include a pyrolysis device, a hydroprocessor and a gasifier. Biomass, such as wood chips, is fed into the pyrolysis device to produce char and pyrolysis vapors. Pyrolysis vapors are processed in the hydroprocessor, such as a deoxygenation device, to produce hydrocarbons, light gas, and water. Water and char produced by the system can be used in the gasifier to produce carbon monoxide and hydrogen, which may be recycled back to the pyrolysis device and/or hydroprocessor.

A process for facile separation of lighter hydrocarbon fractions from the heavier fractions of hydrocarbon oil feedstocks is disclosed, which utilizes novel sparging and reverse distillation techniques. The present invention can be utilized for the facile “topping” of crude oil extracted on-site. Moreover, while heavier hydrocarbon fractions may be shipped to refineries for further processing, this invention will also prove useful for quick separation of light fractions produced by cracking processes off-site.

The various processes of an ethane cracker plant may be segmented into separate process blocks, which may be interconnected using fluid conduits and/or electrical connections. These process blocks may be directly connected, for example without an external piperack or other external piping interconnecting process blocks. Each process block may be formed of one or more modules The process blocks can include an ethane cracking furnace, a steam generation process, a water stripper, a water quench, a compression, a caustic scrubber, a drier, a deethanizer, an acetylene conversion, a demethanizer, a refrigerator, or a splitter.

A process for capturing carbon dioxide includes the steps of mixing a hydrogen stream and a feedstock stream to produce a mixed stream, wherein the feedstock stream includes hydrocarbons, reacting the hydrocarbons and the hydrogen in the primary reactor of the hydroprocessing unit to produce a hydroprocessing product stream and a carbon dioxide stream, wherein the hydroprocessing product stream includes light products, wherein the hydroprocessing unit is further configured to produce ammonium bisulfide, collecting the ammonium bisulfide in the water to produce a sour water, processing the sour water in the waste water unit to produce an ammonia stream, a hydrogen sulfide stream, and a stripped water stream, introducing the ammonia stream to a carbon dioxide recovery system, and separating carbon dioxide from the carbon dioxide stream using the ammonia in the ammonia stream to produce a carbon dioxide product.
