P 115 J3 PPE Sourcing

J3 PPE Sourcing

Having seen the basic engineering of requirement identification, let us see how we went through the exercise of each area specific requirement, common inter-changeable devices across the JMD complex, procurement strategy coordination etc.

Let us see , how and why  each item of that much quantity became essential  and how we went about sourcing them. For that it is better that we analyse item wise.

SCABA set with accessories: As this item fall under fire emergency requirement, JMD fire department took the lead in arriving at the quantity requirement based on strategic deployment factors. As their home work was perfect, we did not face any trouble. The only point where we had discussions was about choice selection of newly introduced Data pad vs conventional modem operated laptop. We opted for latest technology and Mr Aravind Induchoodan of JMD Fire department managed then on. There were some minor coordination issue between the German based OEM who supplied the valve assembly with that of indigenous air cylinder supplier and pure air filling agency at Ghaziabad. JMD fire department took the lead in resolving the issue with all concerned agencies including the statutory authorities at Nagpur.

Next comes Breathing Air! This is a story by itself.  We had issues about the absolute necessity of BA take-off points in PX IV,C2 Complex as well as old refineries + where all and how many to be provided in gasification reactors and AGR in both DTA and SEZ gasification complex.
Both RTG and JMD CTS members questioned the need for provision  of Breathing Air take-off points in conventional hydrocarbon processing plants and petrochemicals. AR as fundamental infrastructural Project manager and control system engineer with safety as specialization, could explain and convince them about probable presence of H2S, Benzene, Toluene,Ammonia + CO due to the latest addition of Syn.gas distribution to all power plants and burners in furnaces in conventional refinery/s and petrochemicals. Once they got convinced they fully cooperated in identification exercise in their respective area.

But when it came to Gasification complex, we had different surprise. Firstly, before we came in picture- gasification operations and project team decided to take  breathing air tapping from mid stage of ASU air compressors at 4.5kg/cm2g pressure  but did not proceed with developing P&ID and further detailed engineering. During vendor technical discussions on BA system, the two leading vendors were threatening to walk out stating that their internal safety protocol and EGA codes do not permit them to accept this feed quality of air and its available pressure for BA objective. That was a revelation for me! They were suggesting to go for exclusive high pressure air compressor that too located in far off place from the gasification complex and pipe out the air @6kg/cm2g minimum.
The problem became acute for me since we did not have any free land space with absolutely clean air
anywhere in that area.

A flash came to my mind. As we are using the existing refinery fire water system extended for the respective gasification complex, why not we suggest taking air for this BA objective from respective refinery utility air compressors ? There we also have air pressure @ >7kg/cm2g. which meets the EGA code directive.  During this source identification exercise we also stumbled on another unsafe condition in respective gasification complex!  It seems that factor was noticed during Hazop study of AGR but missed out during overall coordination by principle DEC for gasification complex. I posed that to COE -HSE and  JMD Gasification operations team.
