摘要:
Refinery off gases are treated in a plant in two processing steps, wherein the off gases are first scrubbed in a wash column using lean oils for removal of heavy mercaptans and C5+ hydrocarbons, and wherein a hydrotreater is then used for saturating olefinic hydrocarbons and reducing sulfurous compounds. Most preferably, lean recycle oil is used for temperature control of the hydrotreater reactor(s) in configurations where the lean oil from a hydrotreater reactor outlet separator is mixed with the reactor feed to so cool the hydrotreater reactor via evaporation.

The system (1) serves for generating a discrete liquid phase in a continuous liquid phase having a first liquid or a second liquid. The two liquids coexist as separate phases, have different densities and permit a desired mass transfer. The invention provides arranging the system in a container (9) which contains the second liquid forming the continuous phase. The system comprises, in a horizontal length extension, a distributor element (2), in particular a cylindrical tube, and a collection channel (3) for the first liquid. The collection channel has an exit side (4), a collection side (5) and at least one side wall (6) connecting the exit side and the collection side. The side wall (6) produces a connection between the outlet side and a horizontal dripping edge (7). This side wall has an inclination or shape which enables the formation of a liquid film of the discrete liquid phase. In order to increase the stability of the film, the side wall (6) can have a good wettability for the first liquid. The dripping edge or the side wall advantageously has a profiling, in particular toothing (70) for generating the discrete phase in the form of drops which are preferably of equal size on account of their uniform toothing.

Disclosed are a Fischer-Tropsch (FT) gas-to-liquid (GTL) apparatus for producing unitary synthetic crude oil and an FT GTL method for producing unitary synthetic crude oil. The FT GTL apparatus for producing unitary synthetic crude oil of the present invention is an FT GTL apparatus for producing unitary synthetic crude oil from floating production, storage, and off-loading (FPSO), and characterized by comprising: a gas injection stabilization unit for performing stabilization on the produced natural gas to generate a natural gas condensate; and a modification unit for modifying the natural gas, which has been treated in the gas injection stabilization unit, to produce a synthetic crude oil product.
摘要:
A method of recovering hydrocarbons from hydro carbonaceous materials can include forming a constructed permeability control infrastructure (100). This constructed infrastructure defines a substantially encapsulated volume. A comminuted hydro carbonaceous material can be introduced into the control infrastructure to form a permeable body (120) of hydro carbonaceous material. The permeable body (120) can be heated sufficient to remove hydrocarbons therefrom such as by using heating conduits (118,126). During heating the hydro carbonaceous material is substantially stationary as the constructed infrastructure (100) is a fixed structure. Removed hydrocarbons can be collected as liquid products (136) and gaseous products (140) for further processing, use in the process, and/or use as recovered.

A mobile fluid cracking catalyst injection system (200) and a method of controlling a fluid catalyst cracking process is provided. In one embodiment, a mobile fluid catalyst cracking system includes a transportable platform (212), a catalyst reservoir coupled to the platform and a flow control device coupled (206) to an outlet of the reservoir and adapted to control the flow of catalyst from the reservoir to a fluid catalyst cracking unit (FCCU).
摘要:
This invention is related to integrated systems for offshore or land based industrial activities which use for feedstock or produce gas, crude oil and/or refined petroleum products/components, and provide reservoir injection of fume gases, can receive and store CO2 or flue gases from other offshore or onshore industrial processes or hydrocarbon producing installations, and can provide industrial products, the generation and transmission of electric power and communications between the various elements or units within a defined network or grid. The at least one industrial activity is represented by combinations of at least one hydrocarbon producing installation, at least one distillation unit, at least one upgrading unit, oil refinery, combined cycle electric power plant, production of heat, production of steam, production of at least one fertilizer, production of at least one petrochemical product. A most favorable integrated system can detect and measure the demand, include applying and the control of fogging of the at least one gas turbine (5) and provide and control wet compression (7), generate electric power accordingly by a combined cycle gas combustion process, and provide the optimization (minimization) of O2, enabling the reinjection of the fume gases (CO2 + N2) into producing HC reservoirs, thus provide pressure support for enhanced HC recovery. Associated or integrated heat and/or steam production ( from the at least one steam or boiler unit) can facilitate other activities on the at least one installation or distributed to the network (10). The integrated system will control the supply of electric power to the grid or network in question. The control of the system is integrated, coordinated and operated in real time.
