Providing PDP and FEED For New Pet. CO. Projects by APIPCO

Introduction

Process Design Package (PDP) includes a comprehensive set of documentation and technical information. which describes in detail all aspects of designing and implementing a specific industrial process. These documents are very important for engineers, contractor managers and project stakeholders and form a main reference for all activities and decisions related to the project.

And FEED also means basic engineering. which is done after completing the conceptual design or feasibility study. At this stage, before the start of EPC (Engineering, Procurement and Construction). various studies are carried out to find out the technical issues and estimate the initial investment costs. This is usually done as an optional contract or through tendering with EPC contractors. FEED work on a large project like LNG plant takes about 1 year. In fact, FEED or Front End Engineering Design is a part of the basic design of the process. which is a prerequisite for detailed design in many process units. In large process units, “FEED” plays an important role in the formation of detailed design.

FEED

FEED is a preliminary engineering stage where engineers do the preliminary engineering diagram before doing the detailed design. This phase comes right after conceptual design but before detailed engineering drawings in project management. Various studies are conducted as part of FEED to determine the funding required for the project.

The task of carrying out this study is assigned to an EPC (Engineering, Procurement and Construction) contractor or a FEED consultant. However, in most cases, an EPC contractor conducts the FEED study, as the FEED is followed by the EPC phase. Therefore, the findings of the FEED, known as the FEED package, are also necessary for the award of the EPC contract.

PDP

In fact, in general, the process design package (PDP: PROCESS DESIGN PACKAGE) means the activities to provide diagrams and documents related to design and construction by the technology provider, including:

Basic design data

process flow diagram (PDP)

Piping and Instrumentation Diagram (P&ID)

Required Inputs and FEED Products

The accuracy of the FEED project depends on the inputs provided to the FEED engineering contractor. The engineering team conducting the FEED requires various inputs for a successful FEED study. This includes:

PDP (Project Development Planning)

Project development planning (PDP) generally includes the following steps:

– Definition of goals and needs: In this step, project goals, market needs, and legal and environmental requirements are defined. Technical and economic analysis: review and technical and economic analysis of proposed plans to ensure feasibility and profitability.

Preliminary studies: including preliminary technical reviews, evaluation of sources and raw materials and anticipation of possible challenges. Risk assessment: recognition and assessment of project risks, including financial, technical and environmental risks.

Market analysis: examining market needs and forecasting demand for final products.

Investment planning: estimating the necessary capital and developing a schedule for financing.

FEED (Preliminary Engineering Design)

Preliminary Engineering Design (FEED) is the phase that defines the details of the project before the implementation phase and includes the following:

Compilation of technical specifications: preparation of technical documentation including product specifications, technologies used, and required systems.

Detailed design: including simplified diagrams (P&ID), equipment layout and necessary specifications for the facility.

Cost Analysis: Determining more accurate costs for the project and preparing financial forecasts.

Risk management: At this stage, risk management strategies are anticipated to compensate for possible problems.

Schedule: Establishing a more accurate schedule for project execution stages and facility related works.

Safety and standards compliance: reviewing and implementing safety standards and compliance with relevant laws

Operators and Benefits

Creating transparency: PDP and FEED make clear and document all stages and weaknesses and strengths of the project.

Risk reduction: crises can be prevented by better understanding the risks and possible problems.

Optimization of resources: they seek to optimize the use of financial and human resources and help reduce project costs.

Increasing the probability of success: With comprehensive and detailed design, the probability of success of innovative projects increases.

Providing PDP and FEED For Innovative and New Projects in The Petrochemical Oil and Gas Industry

In the petrochemical industry, due to the need for continuous improvement and compliance with environmental, economic and social requirements, innovative and new designs play a key role in the PDP (Process Design Package) and FEED (Preliminary Engineering Design) stages. Below are some of these plans and innovations:

1. Green and Stable Processes

– Design of catalytic processes: the use of new and optimal catalysts to reduce the temperature and pressure of operation, leads to less energy consumption and reduction of production waste.

– Use of renewable raw materials: strengthening efforts to produce petrochemical raw materials from biological sources (such as biodiesel and natural fibers) instead of fossil sources.

2. Advanced Control

– Implementing systems to monitor equipment performance and optimize energy and material consumption in real time.

– Data management systems: using advanced analytics and artificial intelligence to process data related to process performance and identify optimal patterns.

3. Capacity Building and Digital Modeling

– Digital modeling and simulation: creating detailed simulation models of processes in order to analyze and optimize performance, identify weak points and suggest corrections.

– (VR and AR): using virtual and augmented reality technologies to train employees and analyze processes interactively.

4. Designing Modern Processes to Reduce Energy Consumption

– Low temperature and pressure: Sometimes designing processes that work with lower temperature and pressure leads to saving energy and costs.

– Recycled thermal systems: optimizing the design of thermal and refrigeration systems for the reuse of waste heat.

5. Development of New and Special Products
