What is BatchingWhat is Batching

It means transportation of different products in aIt means transportation of different products in a

sequence down the same pipeline. The goal is tosequence down the same pipeline. The goal is to

schedule the volumes of each product transportedschedule the volumes of each product transported

by pipelines and to ensure delivery to the customerby pipelines and to ensure delivery to the customer

INTERFACE MANAGEMENT0808 0909 1010


13/40

1313

In a product pipeline, multiple products are transported

through a common pipeline. Various products are pumpedinside the pipeline one after another .

Since all the products packed inside the pipeline moves at very highvelocity there bound to have some intermixing of products.

These intermixing of two adjoining product inside a pipeline iscalled INTERFACE

To maintain the product quality the interface is normally blended inthe inferior product

Interface generation is dependent on the factors like Pipeline

diameter, velocity of the flow, topography of the land, turbulentflow conditions and the type of products ..

DIFFUSION OF INTERFACE0808--0909--1010


15/40

1. For batch operations a specific volume of petroleum products

is accepted for shipment .

2. The interface of adjacent product batches during anytransportation can sometimes be mixed into one or both of

the adjacent batches.

3. For interface from adjacent batches of different grades ofthe same product, such as regular gasoline, the mixture is

typically blended into the lower grade.

4. This downgrading reduces the volume of the higher qualityproduct.

5. Kerosene is maintained pure w.r.t. HSD and MS. SKO can beblended with MS and HSD.

6. No contamination of any product is allowed in ATF

DIFFUSION OF INTERFACE0808--0909--1010

CALCULATION OF BATCH LENGTH0808--0909--1010


16/40

Depends on Type of product

Destination of product

Expected qty of I/F

Tolerance limit of intermixing in mother product

These batches are able to absorb the I/F at delivery endwithout affecting quality

Example MS/SKO I/F generation say 100 KL => 50 SKO+50 MS

Tolerance limit of SKO in to MS= 1%(say)

Minimum batch length of MS say x 1% SKO means x*1/100=50 so, x=5000 KL.

If MS to be delivered at intermediate TOPs with I/F absorption at end stn,then batch length of MS at source to be= 5000 Kl+ qty of MS to be

delivered to TOPs

2. Monthly process Nos. of each Refinery grade wise decidethe flow rate in each section of pipeline .

3. Refinery gives parcel sizes of crude in accordance to processcycle. Keeping in view the monthly product distribution as

decided by Corporate optimisation group

4. Crude stock at all pipeline location and Refinery as of 1st of

Obtain processing plan(ILP-Industrial Logistics Plan) of refineries for the

month from RHQ.

Obtain crude tankers schedule for the month.

Total crude wise (HS, LS &BH) Monthly plan of MR & PR are split in tobatches as per refineries process cycle and capability

These batches are scheduled in CM & CP sections based on the daily avg.throughput

The batch requirement of CM, CP along with Chaksu stock / ullageavailability are projected on to VC section

g

3535



36/40

These projected requirement of batches are scheduled in VC section.

In the same way as in the CM & CP section, the JR plan is split andschedule into batches in VK section also.

As done at the Chaksu node, the batch requirement of VC, VK along withViramgam stock / ullage availability are projected on to SV section.

These crude batches are scheduled in SV and see the availability ofcrude as per tankers arrival dates at Vadinar.

The above back-ward scheduling is viable when the crude requirement

projected at Vadinar is matched with tankers arrival.

g

3636



37/40

Due to Volatile suppliers market of crude, the procurements of crudehappen not only as per our requirement, but also as per theavailability of crude in the market.

Often this mismatch of our requirement and tanker schedule exists in

the system, hence we have to make forward scheduling as well as perthe tankers schedule.

An optimum batch plan is obtained with this back-forth scheduling.

These schedules get reviewed & updated on daily/ weekly basis asper the actual operations and constraints at Refineries/ Pipelines.
