distillation of air in a cold box unit. The complete Nitrogen plant w-as supplied as a

turnkeypackagebyBHPV,Visakhapatnam,India(BHPV-BharatHeavyPlatesandVessels) in the Year 1986-87.

The existing refrigerating unit had come as a pafi of the turnkey package of high

refrigerantunitfiomtrd,v..t.u,'LavalLimitei,Pune,IndiausingrefrigerantR12.M/s Vulcan Laval Limited is no longer in the field of refrigerant unit at present as

they have sold this business to a third pafiy'

Due to environmental restrictions imposed on the availability and usage of CFC

refrigerant R12, we have switched over to R 134 A for the refrigeration unit on

recommendation olthe original supplier of our Nitrogen plant (M/s BHPV' India) in

the year 2008. The lubrication system was also changed over to POE' lubricant

(EMkarate-RL6SH). The changeover to R i34 A was generally smooth with no ma'ior

problems faced.

I

other major problem faced is the lack of availability of to-prtitot spare pads of M/s

vulcan Laval Limited, Pune , India as they are no longer in this business' Also the

existing refrigeration unit is around 32 yeats old. Due to these reasons' we are

planning to procure a new refrigeration unit'

Accordingly, this Technical Procurement Specification (TPS) is for procurement and l

9.0 SPECIAL REOUIREMENTS OF THE NEW REFRIGERATION LNIT:

1. The new Refrigeration Unit (One No required) is required to cool air as per the design

specifications employing vapour compression system using R 134 Arefrigerant as per

tl"re scope of work and requirements specified'

Z. The refrigeration system should be designed in such a way that the outlet cold air from

refrigeration system should have the specified temperature & pressure and it should

not be contaminated from the refrigerant/ oil/consumables etc. from the refrigeration

system because contaminated air will severely affect the purity of nitrogen and

performance of downstream equipments in the Nitrogen plant. During the process ofiiquefaction and separation of air in to pure nitrogen and waste nitrogen streams (waste

niirogen stream *ill b" rich in oxygen), from the safety point of view also, it is

essential that the cold air is free from the above contaminants.

3. The frigorific (cold) production for liquefaction and distillation of air is basically due

to the expansion of gaseous medium in an expansion turbine along with throttling iexpansion through control valves / other elements; hence it is imperative that the

pressure drop permissible in each equipment / section of process gas (air) is limited to

the specified values (inclusive of the air cooling section in the evaporator forming part

of the refrigeration unit).

4. Due to the above reasons and consideringthe critical nature of the refrigerationunit as

a part of the existing high purity nitrogen plant which has to be highly reliable, safe,

continuous in operation; the necessity of maintaining the air outlet temperature

automatically within the limits uninterrupted, limiting the air pressure drop across the

evaporator within the specified value and ensuring the quality of air delivered from the

refrigeration system are of utmost imporlance.

5. Hence the vendor shall take all precautions in the design, manufacture and supply ofthe complete unit so that the performance, reliability and'safety of the refrigeration

system to cater the stringent requirements of the nitrogen plant are not compromised in

any manner. The Vendor shall therefore review and verify / confirm the specifications

furnished in this TPS to achieve the specified objectives.

6. The thermal performance of present refrigerant R l34A is satisfactory. The

evaporation pressure of R i34 A is substantially lower when compared with other HFC

refrigerants thereby eliminating the possibility of refrigerant carry over to the air in the

evaporator in the event of a leak / other upsets. Also switch over from original CFC

refrigerant R12 to HFC refrigerant R 134 A was done as per the recommendation ofthe OEM of nitrogen plant (M/s BHPV-India). Due to these reasons, the relrigerant R

134 Ais proposed to be used for the new system.

7. Also as the existing refrigeration system (Ref Schematic drawing enclosed) was giving

overall satisfactory performance; the new refrigeration system shall be generally as per

the existing system and in accordance with the TPS. Also the problems noted in the

existing system shall be suitably addressed in the offered system.

8. The oil separation and return system shall be designed to ensure that oil is adequately

returned to the compressor and does not collect in the heat exchangers or other parls ofthe system.

All vessels shall be designed and manufactured as per ASME Section VIII orequivalent international code / standard for unfired.pressure vessels.

The Unit shall be capable of continuous stable operation at full load and part load

conditions up to the- tumdown range. Also during continuous operation of the

refrigeration system at varying refrigerant loads from full load up to turndown, the

outlet air temperature shall be maintained automatically and the maximum variationpermitted shall be limited to the existing limit values (maximum permitted variation

of air outlet temperature shall be from 5oC to 8oC presently maintained). As noted

earlier, the lower limit of 5'C is maintained as a safeguard against tripping of the uniton antifreeze thermostat.

There shall also be a trip of tl-re unit @ 4'C (anti-freeze thermostat) for the outlet air.

Additionally, the pressuie drop of airln the evaporator shall be limited to 0.3 Kg/cm2

when dischargfi.ud pr.rru.e exceeds the set point. Only manual resetting shall be

provided for this safetY.

ii) Low suction pressure (LP) safety (cut-out) to stop the compressor automatically, in

case suction p..rr.,r. falls below a pre-set value. This safety shall operate when the

suction pressgre falls below the set point. Automatic resetting shall be provided for

this safety, with adjuslable cut in and cut-out pressures. This safety shall be used for

pumping down the system for shutting off the refrigeration plant.

iii) Oil pressure (O.P) safety (cut-outs) to stop the compressor, in case lubricating oil

pressure falls below a safe set value. A time delay mechanism shall also be

provided, so as to permit running of the compressol up to a maximum period of 90

ieconds, with the oil pressure differential below the set value and allow it tocontinue normal operation if the pressure differential builds up to the set value

within that time, or otherwise shut-down the compressor. Only manual resetting

shall be Provided for this safetY.

iv) Time delay mechanism on the starting gear to limit short cycling regardless of mal-

functioning of controls.

The cut-outs (i) to (iv) mentioned above shall operate when the respective controlled

variable crosses the set point to trip the compressor. Audio visual alarm shall be

provided to indicate such operations. A manual reset shall be provided for them.
