NotesIs slugging to be considered, pigging operations? Is the flow instantaneous? Are the design factors reasonable, is anything known about the expected future flows of the well, is there a large pressure drop immediately upstream of the process or unit? Will a small change in the conditions or composition create a large change or upset in the process. IS FOAMING AN ISSUE. Address each of these concerns and explain why they should or should not be considered during the preliminary design phase.

Product SpecificationsBriefly reiterate the process objective and create a table which lists all of the expected outlet conditions. (such as RVP, water content, carryover, system losses) State weather a process guarantee is expected and if it should be provided by CPE or an internals’ provider such as SULZER or FABCO
