DATASHEETS a)

After Mechanical / Instrument Engineering create the equipment / instrument datasheets, the Process Engineering Group input the process data required. When complete, the datasheets are returned to Mechanical / Instrument Engineering.

b)

The Process Engineering Group provides process data for: • • •

Equipment and packaged systems Instruments Utility system equipment

Flowchart 3002 outlines the process for the production of datasheets.

6.4

6.5

PROCESS SIMULATION a)

The Process Engineer(s) assigned to a project is responsible for carrying out the process simulations assigned by the Lead Process Engineer.

b)

Process simulations are performed before the heat and material balance data can be provided to Piping Drafting for inclusion in the PFDs.

c)

All process simulations are approved by the Lead Process Engineer prior to issue. Flowchart 3003 outlines the simulation process.

MATERIAL BALANCES a)

The Process Engineer(s) is responsible for preparing material balances for inclusion in the PFDs.

b)

Process simulations must be completed before the material balance data can be produced.

c)

When produced, the material balance data is electronically transferred to the Piping Drafting Discipline for inclusion on the PFDs. The Process Engineer works with the appropriate Piping Drafting Squad Leader to determine whether the material balance is placed on the PFD or on a separate sheet.

Appendix A indicates the data which is generally shown in the material balance tables.

PROCESS STUDIES a)

The purpose of a process study is to investigate various design options and to select one option as the optimum design or confirm a selected design.

b)

The Process Engineer is responsible for undertaking the study which generally requires computer simulations to model the various options.

c)

After computer simulations are completed, equipment sizes/duties are calculated, from which equipment costs can then be generated (by others). Assuming that all options considered meet process requirements, the study will consider other factors, such as capital cost, operating cost, and payback.

d)

The Lead Process Engineer is responsible for reviewing and approving the studies before distribution to other disciplines.

e)

The Lead Process Engineer is responsible for obtaining Customer approval for the process studies.

PROCESS CALCULATIONS a)

The Process Engineer is responsible for the design of the systems assigned to him by the Lead Process Engineer. After process simulations are complete and the process conditions are fixed, equipment sizing and rating is performed.

b)

Flowchart 3004 outlines the process to be followed for process calculations and their approval. Industry codes and Customer standards are used to size vessels and tanks, calculate heat exchanger and air cooler design duties, and pump and compressor horsepower and line sizes.
