SYNOPSIS

This Air System Design is mainly for the application of offshore platform and applicable for onshore facilities as well which having similar requirements.

This course is about determining the proper compressor capacity (supply) to install to satisfy the system compressed air usage (demand) is a vital and fundamental that is often misunderstood. It is very important to understand that the flow requirements of all pneumatic users; the amount of compressed to a desired pressure, required quality (mainly from moisture free quality) required to operate valves (control valves, shutdown valves, blowdown valves, etc.), pneumatic tools, nitrogen generator, and other utility consumptions. Determining the total demand of a compressed air system can be a complicated and oftentimes confusing task, especially in large systems with many end users.

Understanding our constituents of demand is the first step to properly sizing the air system by considering all users which later ultimately will dictate the sizing requirement of air compressor, air receiver vessel, dryer package, instrument air (IA) receiver, and nitrogen generator package. Increases in the demand of a current facility from new users or sizing of air system for new facility which is mainly for calculating the demand of compressed air system can be difficult due to the fluctuating demand of each air-consuming application. Nonetheless, understanding demand begins with summing the average air consumption of each user and putting some margin by investigate continuous and/or intermittent users for the optimum design.

The primary goal of a compressed air system is to deliver a reliable supply of clean, dry, compressed air at a stable pressure to every end user within the compressed air system, at the lowest cost possible. Many factors must be considered when designing a compressed air system to ensure its efficiency, reliability, and safety.

By attending this course, all attendees should be able to relate the requirements of air demand to cover all the users inclusive of direct (utility air) and indirect users (instrument air and inlet to nitrogen generator) which will be the basis for sizing of comprehensive design for new facility or existing facility.


Target Group: Project Mangers, Engineers (e.g., Process/Chemical engineers, Instrument engineers, Mechanical engineers, discipline engineers) any party involving in asset and facility engineering dealing with Air System Design and Operation.


BIODATA OF SPEAKER

Ir. Anwar Ahmad is a registered Professional Engineer with Practicing Certificate (PEPC) with Board of  Engineer, Malaysia (BEM), Chartered Engineer from Engineering Council, UK, Corporate Member with Institute of Engineers, Malaysia (IEM), and Corporate Member with Institute of Chemical Engineers, UK (IChemE) UK with more than eighteen (18) years of experience in process engineering in oil and gas industry.

Responsible to carry out detailed process engineering tasks such as development of PFDs, UFDs, P&IDs, heat and material balance (process simulation), equipment sizing, relief and blowdown analysis, and hydraulic calculations. Also involved in various safety review such as Process Safeguarding Diagram, HAZOP, and SIL workshop.

Experienced in process simulations (Hysys, PetroSim, and VMGSim/iCON), heat exchanger rating software (HTRI), flare network backpressure software (FlareNet/Aspen Flare System Analyzer), and flare radiation study software (FlareSim). Familiar and experienced in using oil and gas industry standards (API,
ASTM, etc.) and company standards such as Petronas’ PTS, Shell’s DEP and Iranian
Petroleum Standard. Familiar with Exxon’s DIM.

In addition to the greenfield design works, he has extensive experience in modification and revamp jobs where the executions are reviewed not only from design perspective but as well as enhanced operation approaches. Mainly the revamp jobs are executed from operability, constructability, maintainability, and reliability. The works are executed to ensure all the safety related documents are captured such as Safeguarding Memorandum, Relief and Blowdown (PSVs and BDVs), Safe Chart (for new installed equipment), Piping and Instrumentation Diagram, Cause and Effect Matrix, etc. This is also executed based on site visit findings to ensure the latest as-built information are recorded and considered when performing the debottlenecking or revamp study.

He is one of committee member of Chemical Engineering Technical Division of IEM actively participating in IEM activities, talks, university’s competition as part of panel team, and actively supporting universities within Malaysia being a industrial advisor.
