Abstract: Systems and methods for evaluating the corrosion risk in operations with equipment for the handling an acid gas-containing solutes, e.g., an amine unit for the removal of acid gases such as H2S, CO2, etc., are provided. Input parameter values corresponding to geometrical parameters of at least an equipment (or a portion of an equipment) susceptible to corrosion risk, operating parameters, fluid dynamic properties, and properties of the solute are received by the system. Based on the input values, the systems and methods derive a minimum pressure above which acid gas flashing occurs given the localized pressure drop, causing corrosion in the identified location. In one embodiment, the systems and methods provide an assessment correlating acid gas loadings with the corrosion risk.

Abstract: A valve trim for a pressure reduction valve containing a plurality of high hydraulic flow resistance flowpaths therethrough. Each flowpath comprises at least two inlets (208, 209) and at least one impingement zone (210) having two zone inlets (211, 212) and two zone outlets (213, 214). The zone inlets (211, 212) communicate with the inlets (208, 209) and are arranged substantially 180 degrees to one another. The two zone outlets (213, 214) are arranged substantially perpendicular to the zone inlets (211, 212) such that flow entering the two zone inlets (211, 212) mutually impinges on itself creating an area of high energy loss, and thereafter separates and exits through the zone outlets (213, 214).

Abstract: A method to model the scrubbing of process fluids containing contaminant gases with aqueous scrubbing agents such as water. The method is implemented with the use of a processor that: receives information corresponding to a process fluid and a piping infrastructure in which the fluid flows; receives information corresponding to an injectant and an injector configured to inject the injectant into the fluid; and predicts a droplet size distribution as a function of time based on the received information. The droplet modeling is used to compute the scrubbing rate as a function of time and to correlate with the concentration of the contaminants to be scrubbed, providing a prediction of the contaminant concentration at any given distance from the injector. The prediction is based at least in part on computation of one or more closed-form expressions to describe both the droplet interaction processes and the scrubbing rate.
