Abstract: Disclosed is a collector tray for collecting liquid in a pressure vessel such as a distillation column. The collector tray includes a liquid collecting surface having a curved shape such that the liquid collecting surface is generally upwardly concave or upwardly convex, and includes at least one chimney through the collector tray. The collector tray can be formed by attaching a plurality of collector tray panels to one another to form the collector tray having the liquid collecting surface. Methods for installing the collector tray and retrofitting a pressure vessel are also disclosed.

Abstract: A pressure sensor for sensing pressure of a fluid includes a diaphragm flexure and a crystal retaining flexure. The diaphragm flexure is designed to exert imparted force on the crystal retaining flexure. The imparted force is proportional to fluid pressure exerted on the diaphragm flexure. The pressure sensor further includes a resonator having a round outer perimeter. A portion of the crystal retaining flexure is positioned between the diaphragm flexure and the resonator. The crystal retaining flexure is designed to exert a load on the resonator. The load results from the imparted force exerted on the crystal retaining flexure by the diaphragm flexure.

Abstract: In an embodiment of the disclosure, mixtures of different carbon length alcohols are used as the primary feedstock for Guerbet alcohols. Specifically, embodiments relate to a method of synthesizing mixed molecular weight additives from a mixture of primary alcohols comprising, receiving a mixture of primary alcohols having greater than two different chain length primary alcohols and reacting the mixture of primary alcohols in a single reactor to produce a mixture of at least five Guerbet alcohols. The mixture of Guerbet alcohols can then be used to produce an additive or surfactant composition comprising additives or surfactants of different molecular weights.

Abstract: Disclosed are an inlet distributor device and its use in a separation vessel for separating liquid and gas. The separation vessel also includes a mist elimination device for removing vapor droplets. The inlet distributor device includes a distributor body of a rigid material having a partially enclosed three-dimensional shape, a distributor inlet adapted to be fitted to the vessel inlet such that the distributor body is positioned internally within the vessel, and a mesh material within the volume of the distributor body. Also disclosed is a method for designing the inlet distributor device. A mesh file representing the separation vessel, the mist elimination device and the inlet distributor device is generated using estimated design parameters of the separation vessel and estimated coordinates defining the distributor body. A computational fluid dynamics software package is utilized to simulate fluid behavior of fluid flowing in and through the separation vessel and solve for fluid behavior based on known and estimated variables, operating conditions and mesh material parameters. The estimated design parameters and geometry of the inlet mesh distributor, estimated variables, operating conditions and/or mesh material parameters are modified as needed until the desired fluid behavior is obtained such that the mist elimination device in the separation vessel is not overloaded with liquid droplets and velocities in the mist elimination devices are within a design velocity range.

Abstract: A process for removing non-volatile, particulate mercury from crudes and condensates is disclosed. Particulate mercury in crudes can be removed by a process of first adding a halogen, such as I2. The halogen converts at least 10% of the particulate mercury into an oil-soluble mercury compound that cannot be removed by filtration or centrifugation. This oil-soluble mercury compound can then be removed by adsorption onto a solid adsorbent. The process can operate at near ambient conditions. The adsorption step can be carried out by mixing a particulate adsorbent in the halogen-treated crude and then removing it by centrifugation, desalting, filtration, hydrocyclone or by settling.
