1 INTRODUCTION
M/s Hindustan Petroleum Corporation Ltd. (HPCL) proposes to install Vapour Recovery
Unit at their Tank Truck and Tank Wagon loading Gantry at White Oil Terminal coming up
in Vishakhapattnam (Andhra Pradesh), India. The main objective is to reduce the emission
by maximizing the recovery of MS and Naphtha vapours displaced during tank wagon and
tank truck loading operations. The targeted emission should be less than 5 gms of
hydrocarbon per Normal cubic meter of vapour/air mixture at the VRU outlet with VOC
reduction to 99.5% to meet the requirements stipulated by the Ministry of Environment and
Forest, Government of India.
The Terminal is presently equipped with one full spur BTPN wagons loading facilities and
two gantries of Tank Truck loading operation. This document defines the requirement of the
VRU system. Vendor to suggest suitable optimized VRU scheme for loading of MS and
Naphtha considering all safety aspects.

2 PROCESS DESCRIPTION
2.1 Vapour Recovery System for MS and Naphtha
Since vapour pressure of Motor Spirit (MS) both variants and Naphtha are high i.e. 0.7
kg/cm2a, during handling they may flash and produce vapours. Vapour recovery/return
arms are provided along with liquid loading arms (supplied by others).
MS and Naphtha systems will be provided with vapour collection system for both tank
wagon loading and tank truck loading arms.
For Tank Trucks loading, 5 nos. vapour recovery arms shall be provided for MS (including
2 future) and 3 nos. vapour recovery arms shall be provided for Naphtha.
For Tank Wagon loading, 48 nos. each vapour recovery arms shall be provided for MS and
Naphtha respectively.
These vapour recovery arms will be connected to the vapour recovery system by laying a
ducting arrangement. Activated carbon is used to adsorb the volatiles and the vapours are
recovered after desorption. This system is provided to save the loss of volatile product
during loading and limiting the vapour emission to atmosphere.
The mean concentration of vapours in the exhaust from the Vapour Recovery Unit shall not
exceed 5 gms/Nm3. 1.2 litre of Gasoline or Naphtha recovered for every kilo litre of
Gasoline or Naphtha loaded for average concentration of 45% in the inlet vapour.
Vapour from the loading points for MS and Naphtha is collected through collection system
and passed through the vapour header to the recovery unit. The header is protected with
detonation proof flame arresters at each end of the line.
Prior to the vapour entering the VRU (Vapour Recovery Unit) it passes through a knock-out
vessel to ensure that no liquid gasoline enters the carbon bed. In addition it is necessary to
provide an emergency vent for the vapour, in the event that the VRU is shut down.
The VRU consists of activated carbon beds (exact number of carbon beds required shall be
designed by VRU vendor), the one being connected to the vapour line - "adsorption mode" -
while the other undergoes regeneration by means of vacuum. Activated carbon has an
extremely high surface area in relation to volume and the hydrocarbons are adsorbed in a
very thin layer on the surface of the carbon. The carbon can only adsorb a given amount
before it approaches saturation. If this occurs throughout the bed, then the vapours will pass
through untreated. Consequently the carbon must be regenerated in order to restore its
capacity, so that it can effectively adsorb hydrocarbons in the following cycle.
The regeneration takes place in 2 stages. First the bed is evacuated until the pressure
reaches to that at which the hydrocarbons begin to desorb from the carbon. The bulk of the
hydrocarbons are removed in this stage. In order to remove the remainder, it is necessary to
introduce a small amount of purge air, to complete the regeneration.
Suitable vacuum pump used with air cooling to limit the temperature rise over the pump.
The vapour, rich in hydrocarbons, passes into the absorber column where the bulk of the
hydrocarbon is absorbed in a counter flow of Gasoline/Naphtha. The small amount of air
present, particularly during the purge stage, passes out of the top of the absorber column

and results in a small carry over of hydrocarbons, which is returned to the carbon bed,
which is in adsorption mode. The unit is provided with an automatic energy saving
function: If vapour loading is low or has stopped, all functions are set on stand by, once all
carbon beds have been thoroughly regenerated. When on stand by, the unit is still open for
adsorption, but all the pumps are stopped. The pumps only operate occasionally for short
intervals to keep the carbon beds clean and active. When normal load resumes, the plant
will automatically restart, with continuous pump operation after getting signal from the
hydrocarbon analysers in the vapour collection header. VRU shall start only when the
vapour concentration reach a desired level. All the rotary equipments (pumps) shall have
one working and one installed standby. All the rotary equipments shall be on VFD for
power saving.
This description is typical and vendor can suggest improvements over the described system.

Depending upon the requirement, there may be partial loading of the tank wagon rakes.
Accordingly the number of loading pumps in operations may vary, i.e. system to be
designed shall be able to perform for handling vapour recovery for loading operations
ranging from 288 m3/hr up to 864 m
3/hr. Depending upon the requirement of Tank Truck
loading the VRU should be capable in design to operate from minimum one loading arm
operation (72 m3/hr) to maximum three (for MS and Naphtha combined- 216 m
3/hr max.
flow rate). Hence total vapour handling requirement is 1080 (864 + 216) m3/hr, for
simultaneous Tank Truck and Tank Wagon operations. Suitable design margin shall be
taken by vendor for efficient VRU design.
The VRU system has to be designed for present top loading system of MS and Naphtha for
Tank Truck loading operations. However during future if top loading (for TT) arrangements
are getting converted to bottom loading which has higher loading flow rate requirements,
the VRU should be designed to handle the higher rate of vapour displacement while bottom
loading.
Vendor while design of VRU has to ensure all the simultaneous loading configuration
occurring and suggest a suitable VRU system for MS and Naphtha Loading.
Vendor to optimize VRU system for MS and Naphtha loading.
For the purpose of design one full rake (48 wagons x 68 KL each) of MS or Naphtha is to
be considered per day. Simultaneous loading of Naphtha and MS is not to be considered for
TW. Vendor may suggest any requirement of purging with Nitrogen during any change
over of product from MS to Naphtha and vice versa (Vendor to confirm).
Vendor to confirm the requirement of dedicated recovery headers for MS and Naphtha.
