National Refinery Limited

New CUIN Registration number 0001747 NTN-No 0711325-7



Following projects are currently being executed by the company:

Replacement of Utilities Control System with centralized Distributed Control Systems
Replacement of existing control system of Utilities with Distributed Control System (DCS) is in progress which will ensure high-integrity process controls, process safeguarding and emergency shutdown. It will also improve process control and monitoring of boilers parameters, availability of customized reports and log sheets and optimum Human resource utilization. Distributed Control System (DCS) has been installed successfully at Boiler V and VII whereas, installation at boiler VI is expected to be completed by June 2022.



Two stage unit revamp at Lube-I refinery
The project has been commissioned in September 2020 and it has enhanced the installed crude oil processing capacity of Lube-I refinery from 12,050 Barrel per stream day (bpsd) to 17,000 bpsd and vacuum fractionation capacity from 5,200 bpsd to 6,600 bpsd.


New Sea Water Reverse Osmosis Plant
New sea Water Reverse Osmosis plant with capacity of 250,000 US gallons per day has been procured and installed following the completion of Phase-I projects to meet the increased water requirement. Project Commissioned in October 2019.


101-F-1 Air Pre-Heater Project:

Installation of Air Pre-Heater at fuel refinery is an energy saving and environmental friendly project. Furthermore, Greenhouse gases emissions and carbon foot prints are significantly reduced. The project has been completed and commissioned in August 2018 at a cost of Rs. 425 million.


Your company successfully completed the following projects during the year 2017-18.

Up-gradation of existing Turbo Generator Steam Turbine at power generation has been replaced by a multi-extraction back pressure turbine.

This has reduced the overall per unit cost of internally generated electricity. The project was awarded to M/s Siemens Pakistan Engineering Co. Limited, which has been completed in December 2017.

Water Demineralization plant

Water demineralization plant for Reverse Osmosis was successfully installed and commissioned in June 2018. This will help in overcoming the company’s water requirements by improving the quality of available water from Reverse Osmosis plants.

Implementation of DCS at Lube-I Refinery

Distributed Control System from YOKOGAWA has been installed at Lube-I refinery and all Lube-I refinery units are operating on new system.

Waste heat recovery boiler

With planning to utilize the heat energy used to be vented to the atmosphere from the Diesel Generator, the project has been successfully completed in February 2018.


Installation and Commissioning of used Diesel Generator of 8.2 MW

The energy demand of the company increased due to upgradation projects. In order to meet the power requirement the company procured used Diesel Generator of 8.2 MW capacity, which was successfully installed. The generator is meeting the company’s electricity requirements.

Up gradation of existing Turbo Generator
Steam Turbine at power generation is being replaced by a multi-extraction back pressure turbine. This will reduce the overall per unit cost of internally generated electricity. The project was awarded to M/s Siemens Engineering Pakistan and has been successfully completed in September 2017.


Nitrogen Gas Generator

For the purpose of financial economization, Nitrogen Gas Generator having capacity of 400 Normal Cubic Meter/Hour has been installed. Nitrogen Gas will be used as inert media for MEK Units. The Project was successfully commissioned in November 2015.

Reverse Osmosis Plant

The Company already has three water Reverse Osmosis Plants with designed capacity of 100,000, 200,000 and 250,000 gallons per day respectively. Considering the scarcity of water and its requirement for refinery operations Company has installed Reverse Osmosis plant IV having capacity of 250,000 gallons per day. The Plant has been commissioned in June 2016.

Effluent Treatment Plant

The Effluent Treatment Plant is used to clear water from contaminants. The recovered oil is re-used and water is diverted as feed stock for RO plants. The plant has been installed and commissioned in June 2016.


Addition of Storage Tanks
In order to meet the rapidly changing market demands and to increase the operational flexibility, the storage capacities of crude oil and various products i.e Furnace Oil, Lube Base Oil, HSD, Asphalt and JP-1 were enhanced by addition of nine storage tanks.

New Water Reservoir
To cater for acute shortage of water during summer season, a new water reservoir having capacity of three million gallons has been added.
