ProTreat® Software

ProTreat® software was originally developed for simulating processes for the removal of H2S, CO2, and mercaptans from a variety of high and low pressure gas streams by absorption into thermally regenerable aqueous solutions containing one or more amines. ProTreat has since been expanded to include many proprietary amines (GAS/SPEC, UCARSOL, AdapT), the physical solvent DMPEG (dimethylether of polyethyleneglycol) for acid gas removal, and dehydration using glycols (MEG, DEG, TEG) as well as piperazine promoted MDEA, AMP, glycinates, promoted HotPot, ammonia, caustic, Coastal AGR. Our latest addition is kinetics-based simulation of sulphur recovery units.

ProTreat® simulation makes exclusive use of a column model that treats the separation as a mass transfer rate process. This completely eliminates the need for empirical adjustments to simulate new applications correctly. Equilibrium stages and user-supplied estimates of tray efficiencies and HETPs are avoided, and columns are modeled with the number of real trays and physical depth of real packing they actually contain.

ProTreat® simulation never require translation of theoretical stages or NTU's into actual tray counts or bed depths of real packing. The ProTreat® mass transfer rate model deals with real trays and packing right from the outset. It calculates the separation achievable by the specific internals selected for installation in a given tower shell (including swages) with complete reliability. Even such details as the number of tray passes is considered.

The ProTreat® package has the full flexibility needed to allow any imaginable flowsheet for amine-based acid gas removal process and any sulphur recovery process to be constructed and simulated as a fully integrated plant including AGR, AGE, SRU and TGU in one flowsheet. From the user's perspective, drawing functionality is similar to Corel Draw. A flexible flow-sheeting capability is needed when simulating processes with the complexity often found in refineries.
