Abstract

Provided is a process for converting waste plastic into recycle for polyethylene polymerization. The process comprises selecting waste plastics containing polyethylene and/or polypropylene. These waste plastics are then passed through a pyrolysis reactor to thermally crack at least a portion of the polyolefin waste and produce a pyrolyzed effluent. The pyrolyzed effluent is separated into offgas, a pyrolysis oil comprising a naphtha/diesel and heavy fraction, and char. The pyrolysis oil is then passed to a hydroconversion reactor comprising an LTA zeolite based catalyst having an acid site concentration of about 2.7 mol/l. Effluent from the hydroconversion reactor is then sent to a steam cracker.

Abstract

Metocean conditions for a wellhead, such as current profile and wave characteristics, are used to determine wellhead fatigue damage rate for the wellhead. The wellhead fatigue damage rate is determined using an interpolation approach or an extrapolation approach. In the interpolation approach, the metocean conditions of the wellhead are input into one of multiple clustered machine learning models to determine the wellhead fatigue damage rate. In the extrapolation approach, a curve is generated to fit cluster centers of the multiple clustered machine learning models, and the wellhead fatigue damage rate is determined based on the curve and the distance between the metocean conditions of the wellhead and null metocean conditions.

Abstract

A lipid feedstock including fatty acid(s) is treated in a process flow through a moving bed reactor with catalyst to produce a treated stream. The catalyst may include metal oxide catalyst on a particulate oxide support. The catalyst may be transferred, using a catalyst withdrawal line, from the bottom of the moving bed reactor to a fluidized bed regenerator, and regenerated. The catalyst may be transferred from the fluidized bed regenerator to a cyclone that separates the catalyst from flue gas. The catalyst may be transferred from the cyclone to the top of the moving bed reactor using a catalyst feed line. A first separation gas may be flowed into the catalyst feedline, and a second separation gas may be flowed into the bottom of the moving bed reactor or into the catalyst withdrawal line, to generate pressure differentials driving the process flow through the moving bed reactor.

Abstract

Asphaltene simulation is performed by modeling asphaltene using physical changes. A pseudo-component framework is used to simulate asphaltene precipitation, asphaltene flocculation, and asphaltene deposition in a subsurface region. The pseudo-component framework for asphaltene simulation treats asphaltene precipitation, asphaltene flocculation, and asphaltene deposition as physical changes of a single component, rather than as chemical changes. Use of the pseudo-component framework for asphaltene simulation reduces complexity of asphaltene simulation. For example, use of the pseudo-component framework for asphaltene simulation enables tracking of asphaltene as it is found in different states (precipitated, flocculated, deposited). Use of the pseudo-component framework for asphaltene simulation enables chemical reactions to be replaced by a flash and adsorption framework. Asphaltene simulation using the pseudo-component framework exhibits stable and fast convergence.

Abstract

A method of separating gas and liquid within a well bore includes positioning a production tube within the well bore such that the production tube extends from a subterranean reservoir, traverses a gas cap, and out of the production well bore. An in-situ downhole separation system is configured such that during production, produced fluid enters a separation zone formed in the well bore. The fluid flows within the separation zone in a direction from the reservoir and toward the gas cap, and at least some gas of the produced fluid separates from liquid of the produced fluid as separated gas that is reinjected into the gas cap. The remaining fluid is withdrawn through the production tube. Additional amounts of the gas may be separated from the liquid using a gas liquid separation device and/or a pump mechanism of the in-situ downhole separation system.

Abstract

A stabilizer attached to a marine tubular assists in inhibiting movement of the marine tubular when it is subjected to forces from ocean currents and waves encountered in subsea and shore crossing zones. The stabilizer includes a first plate and a second plate that are joined on opposite sides of the marine tubular. The stabilizer also includes one or more tubercles that extend from the stabilizer and inhibit motion of the marine tubular. A hydrodynamic shape of the one or more tubercles reduces drag as ocean currents flow over the stabilizer. The tubercle also can increase the moment arm of the stabilizer thereby inhibiting overturning of the stabilizer. The surfaces of the tubercle are shaped to promote the flow of ocean water below the stabilizer when the marine tubular is laid on a seabed or shore crossing zone.

Abstract

A process of preconcentrating CO2 in an exhaust gas stream includes flowing all the exhaust gas stream from an exhaust gas source to a CO2 preconcentration system. Within the CO2 preconcentration system, at least a portion of the exhaust gas stream is fed to a membrane separation module comprising a polymeric membrane that has a perm-selectivity for CO2 over N2 and O2, to produce a CO2 rich exhaust gas. The exhaust gas stream may initially have as low as 400 ppm CO2 and may be preconcentrated to over 8 vol. % CO2, thereby generating a more optimal feed for further treatment processes.

Abstract

A method of making a cement composite can include contacting an aqueous solution comprising calcium ions with a carbon dioxide source producing a carbonated aqueous solution. Fine particles can be submerged in the carbonated aqueous solution to produce microaggregate particles comprising the fine particles coated with calcium carbonate. The microaggregate particles can be combined with cement particles to produce the cement composite. The cement composite can be used in cementing applications for hydrocarbon wells including for casing liners and well plugs.

Abstract

An artificial cable trench (ACT) includes a body and a trench formed into the body. The trench is configured to hold a cable, umbilical, or similar feature. The ACT may be positioned along a seabed or shoreline to stabilize the cable and thereby prevent movement and eventual damage to the cable. The body of the ACT is shaped to overcome the flow induced loads caused by the relative motion between the cable and the surrounding waves and sea currents as well as providing effective friction/engagement with a contact surface (e.g., a shoreline surface). The ACT may have features that result in self-burying in sand and/or preventing lateral movement.

Abstract

The wave characteristics of the water (e.g., ocean) above a wellhead may be used to determine a wave-induced wellhead fatigue damage rate for the wellhead, and the current profile of water around a riser connected to the wellhead may be used to determine a riser vortex-induced vibration caused fatigue damage rate for the wellhead. The wave-induced wellhead fatigue damage rate and the riser vortex-induced vibration caused fatigue damage rate for the wellhead may be combined to obtain the total wellhead fatigue damage rate for the wellhead, which may be used to make operational decisions, such as connections or disconnections, for the well.
