Alternatives Identification

After a process goal (new design, modification of design, etc.) has been determined, one of the first steps in developing a new project is to identify the alternatives that will need to be evaluated. Operating companies usually have identified a list of potential solutions that may ultimately satisfy the process goals.  PROCESS can assist these companies in the identification of other potential solutions that the client may not be aware of, or may not have identified as options.  PROCESS uses sound engineering principles, limited research and it's employee's diverse backgrounds and wealth of experience to help identify options to achieve the process goals.  A list of alternatives is developed as a deliverable with a brief listing of positives and negatives that may be associated with the implementation of these options. 

 

 

Conceptual and Preliminary Process Designs

PROCESS is able to assist clients that are considering installing a new process or modifying an existing process by providing world class chemical engineers that can identify, and systematically narrow down, the possible technical alternatives that can achieve a given process goal. The resulting deliverables from this phase of the project can be customized for your organization's needs.  Our services deliver a package that will give the client the needed data to choose the best process option to move forward with.  PROCESS can also develop a presentation that allows the client to present the results of the preliminary process design to the operating company's management or to investors.

Once the viable technical options are identified by the client's staff or with assistance from PROCESS, baseline process engineering is accomplished and a preliminary economic evaluation is performed. Based on the process technical abilities, system reliability, economics (capital and operating), and other factors, the client can decide how the future process design should proceed. PROCESS will develop a conceptual design suitable for process screening.  Basic process design deliverables for this phase of work typically include a preliminary process design basis, block flow diagrams, preliminary mass & energy balances, preliminary Process Flow Diagrams (PFDs) identification of major equipment requirements, and a very rough cost estimate with accuracy depending on the amount of engineering design work completed.   As a part of services offered, PROCESS can identify potential risks associated with the design (such as difficult to obtain specialty equipment, required pilot testing, insufficient data, risky scale-ups, and similar) so that a plan can be developed to address these issues prior to or during the next phase of the project.

FEL 0 - Identification Phase (Conceptual Process Design or Screening Study)
Industrial project opportunities can target revenue growth; expense reductions; strategic growth; improved safety; improved reliability and/or efficiency; or other goals identified by management. Clients typically identify opportunities by evaluating the value of project implementation and by identifying key risks and uncertainties. It is important to evaluate opportunities on a consistent basis for comparison purposes. The basis for the first decision gate is a high level screening study or conceptual process design study.  This level of work involves reviewing promising chemical conversion pathways or major licensed technologies, narrowing the project down to one or more options, identifying major equipment, developing block flow diagrams, and generating an Order of Magnitude capital cost estimate range.

Deliverables from a standard FEL-0 Package include:

  • Overall Chemical Reactions/Product Pathways
  • Expected Licensed Technologies Needed
  • Block Flow Diagrams
  • Major Equipment Identification
  • Order of Magnitude Capital Cost Estimate

FEL 1 - Appraisal and Selection Phases (Process Appraisal and Preliminary Process Design)

Appraisal

During the appraisal phase of the project a series of processing alternatives and unit operations are analyzed and further assessment of the process value, risk, and uncertainty is conducted. Some examples may include alternatives such as batch versus continuous processing, use of different types of separation techniques (extraction versus distillation, pressure filtration versus a centrifuge), etc. The most promising development concepts progress forward to the Selection phase.

Selection (Preliminary Process Design)

The objective of the Selection phase of the project is to identify a single process concept for progression to the Detailed Process Design phase of the project and to develop base line deliverables that can be further developed in future phases of the project. Preparation of work deliverables requires that a single process concept be selected and further developed during this phase. Once a concept has been selected, the team will complete the level of detail necessary to develop a cost estimate and preliminary project schedule with a typical target accuracy of –30% to +50%. Deliverables at this stage often include the following:

  • Preliminary Process Design Basis
  • Process Alternatives Evaluations Summary
  • Preliminary Process Simulation and Heat and Material Balance Data
  • Preliminary Process Flow Diagrams (PFDs)
  • Preliminary Equipment List
  • Preliminary Major Equipment List with Conditions of Service
  • Preliminary Capital and Operating Cost Estimate (target accuracy of +50% /-30%)
  • Preliminary Summary of Raw Materials and Utility Requirements
  • Process Risk Summary.

 


Detailed Process Designs

FEL-2 / FEL-3, Front End Engineering Design (FEED), or Basic Engineering Packages

Once the process configuration has been clearly defined, a detailed process design package can be prepared.  This package defines the process and identifies the chemical process engineering requirements that other engineering disciplines will build upon in the future.

FEL-2 Process Design Package

The FEL-2 Process Design Package or Front End Engineering Design Package (FEED) will establish the specific set of process operating conditions and equipment necessary to achieve the level of reliability, efficiency, and safety required. This design phase sets the direction for the entire project.   At the completion of this phase of the project, a cost estimate with target accuracies of +40%/-20% can typically be developed.

Typical Process Engineering Deliverables for an FEL-2 package can include the following or a smaller subset of these items:

  • Project Scope Summary
  • Process design basis
    • Raw material specifications
    • Plant capacity requirements
    • Product specifications
    • Critical plant operating parameters
    • Available utilities specifications
    • Individual unit operations performance requirements
    • Process regulatory requirements
    • Other operating goals and constraints desired by the plant owners/operators/engineers.
  • Material & Energy Balance (M&EB)
  • Process Flow Diagrams (PFDs)
  • Process descriptions
  • Utility Balances and Utility Flow Diagrams (UFDs)

  • Preliminary instrument list
  • Process equipment list
  • Preliminary Tie-in list
  • Equipment process datasheets
  • Instrument process datasheets
  • Hydraulic design reports
  • Cost estimate with target of +40%/-20% accuracy.

FEL-3 Detailed Process Design Package

The FEL-3 Package or detailed process design package (PDP), which is sometimes referred to as a Schedule A or Basic Engineering Design (BED) package, refers to a completed process design package that includes all the necessary information required by an Engineering/Construction firm or Detail Engineering firm to perform the final engineering of the plant. PROCESS provides this package and helps to answer any questions the client or engineering firm might have to ensure a smooth transition into the detail engineering phase. PROCESS provides process design packages for both Inside Battery Limits (ISBL) and Outside Battery Limits (OSBL) design requirements.

In addition to updating the items mentioned above in FEL-2, the following items are typically added during the FEL-3 phase.

  • Preliminary general arrangement drawings
  • Preliminary building requirements
  • General description of the project site
  • Budget pricing from vendors on major pieces of equipment
  • Process design philosophies
  • Relief system design basis
  • Relief scenario datasheets and relief valve process datasheets
