    Abstract: Produced water, for example from a steam assisted gravity drainage (SAGD) or cyclic steam stimulation (CSS) heavy oil recovery operation, is treated to recover water that is re-used to create steam. The produced water is treated in one or more thermal treatment devices such as an evaporator and a crystallizer. The thermal treatment device is seeded, for example with a calcium or magnesium salt. The thermal treatment device produces a blowdown or slurry comprising super-saturated solids and organic compounds. A solvent is added to the blowdown or slurry. The solids precipitate and are separated from the blowdown or slurry. The solvent may be recovered for re-use in treating more blowdown or slurry.

    Abstract: Various methods of making a reinforced membrane, devices for making the membranes, and the resulting membranes are described. The methods typically provide a reinforcing structure that includes filaments extending around the circumference of the membrane but without the filaments being part of a braided or woven structure. Some of the reinforcing structures also include longitudinal filaments. The methods and devices can be used to make a supporting structure in line with membrane formation steps, and also allow for a reinforced membrane to be produced that has a ratio of inside-to-outside diameters of 0.5 or more.

    Abstract: Described herein are systems and methods of fouling mitigation in a hydrocarbon fractionation column. The methods correlate operating parameters of the fractionation column, specifically flow rate and temperature, with fouling. The methods can include measuring a temperature and a flow rate at a bottom stream of the hydrocarbon fractionation column; providing the measured temperature and flow rate to a processing device; determining, by the processing device, based on the measured temperature and flow rate of the bottom stream, an antifoulant treatment protocol for the hydrocarbon fractionation column; and treating the hydrocarbon fractionation column by controlling, by the processing device, a feed control unit in accordance with the determined antifoulant treatment protocol.

    Abstract: An underdrain system for a media pressure vessel has a set of removable pipe sections located between an external header and the bottom of a vessel. Septa extend upwards from the removable pipe sections into the vessel by up to 16 inches. The septa may have diameters of 6 inches or more. The header is attached to the bottoms of the removable pipe sections. Each pipe section, and its associated septum, may be removed individually. To clean the vessel. after media is removed from the vessel the pipe sections are removed sequentially while the header remains otherwise attached to the vessel. While a pipe section is removed. its associated septum is removed so that solids can be removed from the annulus between the septum and the vessel. In this way. media can be cleaned from the annuli without moving the external header or entering the vessel.

    Abstract: Various implementations include a device for analyzing total organic carbon (TOC) within a fluid. The device includes a primary container, an input conduit, and an output conduit. The primary container is hollow and has a primary side wall and a primary end wall. The primary side wall has an inner surface defining a primary cavity and an outer surface opposite and spaced apart from the inner surface. The primary end wall includes a septum that is resiliently penetrable by an analyzer needle of a grab analysis port of a TOC analyzer. The input conduit has an input lumen. The input conduit extends through the primary container such that the input lumen is in fluid communication with the primary cavity. The output conduit has an output lumen.

    Abstract: Various implementations include a system and methods for capture and transfer of a liquid sample from a process to a sample analysis device. In particular, a sample of fluid can be contained in a non-pressurized line and first and second air-operated valves may prevent the fluid from flowing through the line. A third air-operated valve may be positioned on a stub-out of the non-pressurized line between the first and second air-operated valves. A sample line, also configured to contain a sample of the fluid, can extend between the third air-operated valve and a sample analysis device to transfer the sample of fluid to the sample analysis device. A first pneumatic valve can control air flow to the first and second air-operated valves; a second pneumatic valve can control air flow to the third air-operated valve; and a third pneumatic valve can control low-pressure air injected into the sample line.
