Systems and methods are provided for separation of COfrom dilute source streams. The systems and methods for the separation can include use of contactors that correspond radial flow adsorbent modules that can allow for efficient contact of CO-containing gas with adsorbent beds while also facilitating use of heat transfer fluids in the vicinity of the adsorbent beds to reduce or minimize temperature variations. In particular, the radial flow adsorbent beds can be alternated with regions of axial flow heat transfer conduits to provide thermal management. The radial flow structure for the adsorbent beds combined with axial flow conduits for heat transfer fluids can allow for sufficient temperature control to either a) reduce or minimize temperature variations within the adsorbent beds or b) facilitate performing the separation using temperature as a swing variable for controlling the working capacity of the adsorbent.

CO2 capture from dilute sources

Systems, methods, and apparatuses for treating petroleum in a container are disclosed herein. The method includes electrically heating a portion of the container to generate heat sufficient to create convection currents in the petroleum. The method also includes stopping heating after the petroleum cools below a threshold temperature. The systems, methods, and apparatuses mitigate yield stress in petroleum susceptible to gelling.

An asphaltenes separation system comprising a flocculant feed system configured to add a flocculant to a production fluid to flocculate asphaltenes in the production fluid, and an asphaltenes separator configured to remove flocculated asphaltenes from the production fluid.

Separation of asphaltenes

A method, including: performing dual-side depressurization on a hydrate blockage in a subsea flow line, wherein dual-side depressurization includes, reducing pressure on a topside of the hydrate blockage in the subsea flow line by removing liquid from within a subsea riser with a bubble pump that has a first end in fluid communication with the liquid within the subsea riser, reducing pressure on a backside of the hydrate blockage, and concurrently controlling the reduction in pressure on the topside of the hydrate blockage and the backside of the hydrate blockage.
