International Classification:

C10G 2900

US Classification:

208207

Abstract:

An improved method of treating streams having mercaptan or mercaptan-based compounds therein particularly adapted for the processes of sweetening sour hydrocarbons and regenerating spent caustic solutions is described. The invention comprises contacting a first stream having the mercaptan or mercaptan-based compounds therein with a second stream in the presence of effective amounts of a nitrogen-based promoter to promote the extraction and/or the catalytic oxidation of the mercaptan compounds therein. The invention herein disclosed and described is applicable in a wide variety of apparatus and processes adapted for sweetening and regeneration operations.

Abstract:

A system, method and computer program product for assessing risk of a process through a set of entities identified as utilizing personal data needing protection from misuse and wrongful disclosure comprising mapping the identified process including identifying a purpose of the identified process and a sensitivity of that purpose; identifying data elements including the utilized personal data and including a volume and sensitivity of those identified data elements; identifying data types including the utilized personal data and including a volume and sensitivity of those identified data types; identifying data subjects about whom data is involved in the process including a volume and sensitivity of those identified data subjects; and identifying the set of entities involved in the process and their locations; and identifying data flows among the set of entities involved in the process; and applying a set of rules against the mapped process to provide a risk assessment of the mapped process based on the risk sensitivity of the process purpose, sensitivity and volume of each data element, data type, and data subject, risk related to the entity locations and data flows among the entity locations.
