Gas Detector Portables
In J3, as Reliance has gone in implementing mega petrochemicals producing C2/C3 basic production from the refineries' off-gas and their corresponding down stream products of MEG, LDPE, LLDPE and IIR/HIIR in petrochemical group and Coke gasification to generate Syn. gas for usage in power plants and heater burners as fuel, we identified the possibility of several gases- hazardous in terms of flammability or toxic in nature release in the plant atmosphere.
With the services of core process team we drew the complete listing of them. When it came to fixed
metering arrangement concerned , the core instrumentation team took care with the services of rspective DEC but the responsibility to identify and source the requirement for portables fell on RPMG LP team.
I took the call and gathered the total type listing from the core process team that too plantwise/area wise. The various gases/vapors are :
Ammonia
Benzene
Butadiene
Butane
Mercapton
CO2
Cl2
HCN
CO
SO2
Cycloxexane
Toluene
EO
Ethane
Ethanol
Ethylene
Propylene
Ethylene Glycol
Gasolene
Glycol
Heptane
Xexene
Hydrogen
H2S
Peroxide
Isobutane
Jet fuel
Diesel
Kerosene
Naphta
Methane
Methanol
Pentane
Octane
Hcl
LPG family
Xylenes
Phenol
Nitrogen......
It took considerable time for me to group them for area specific requirement and arrive at the type of device to be chosen for area monitoring as well as to be issued to each individual for his/ her personal safety. While carrying out this exercise, I became knowledgeable that each competing vendor has got different special features to offer. It became a challenge to me to select which of the special features to be given special merit while freezing the specification and develop the TBE to be issued to procurement. I did not want to go with multi vendor selection option for the specific reason of accumulating the data in single server for plant performance analysis during steady state operating conditions. As an experienced petrochemical instrumentation engineer with 47 years project exposure in refinery projects, I decided that we can go with Zone '1' approved devices , though a particular vendor claimed that he has got zone'0' approval for some of their devices but not all. Even for that vendor, when I went deep in analyzing his claim by reviewing their ATEX certificates, I noticed the folly and warned that vendor for their false statement and forced to withdarw the claim then.
There came a controversy! The core CHSEE did not believe my contention and raised technical objection of opting Zone'1' instead of zone'0'. Fortunately BNarayan and DDutta being chemical engineers by qualification, understood the situation and cleared my stand and backed me.
