Thesis (M.Eng.)--Memorial University of Newfoundland, 2010. Engineering and Applied Science Includes bibliographical references (leaves 158-163) High temperature and pressure conditions occur very frequently in the oil and gas operation. A variety of oil field chemicals, such as corrosion inhibitors and hydrogen sulfide scavengers, are commonly used. These two chemicals are generally hydrocarbons, volatile and vulnerable in heating conditions. The objective of this work is to evaluate the hazard associated with three liquid (Nox Rust 1100, Nox Rust 9800, and Brenntag) and one solid (VCI 1 powder) corrosion inhibitors, and one hydrogen sulfide scavenger formulated with Formaldehyde and Monoethanolamine. -- The Vent Sizing Package (VSP2) and the Advanced Reactive System Screening Tool (ARSST) are used to evaluate the thermal properties for hazard assessment and vent sizing. ARSST is used for rapidly screening and characterizing the system, and it provides directly scalable relief-system design data for reactive systems. Whereas, VSP2 continuously tracks pressure and adiabatic temperature which makes it a useful tool for measuring temperature and pressure rise rates. Vent sizing methods such as Leung's, Fauske's standard, and Fauske's short form equation are applied to the studied systems. The derived vent sizing areas are compared to determine the most appropriate one. -- The studied corrosion inhibitors and the hydrogen sulfide scavenger show three kinds of system behaviors: non-reactive vapor, reactive vapor and gassy. The hydrogen sulfide scavenger sample is found to be the most reactive sample with two exotherms. Among the corrosion inhibitors, Nox Rust 9800 requires the largest area to volume ratio (2.15 × 10 -4 m -1 ) and VCI 1 powder require the lowest (7.26 × 10-6 m-1 ).
