ONGOING PROJECTS

Following projects are currently being executed by the company:

Waste heat recovery boiler
It is planned to utilize the heat energy currently being vented to the atmosphere from the Diesel Generator. Project has been awarded to the contractor and engineering work is in progress with expected date of completion uptill March 2018.

Two stage unit at Lube-I refinery
The project has been planned to enhance the installed crude oil processing capacity from 12,050 Barrel per stream day (bpsd) to 17,000 bpsd and vacuum fractionation capacity from 5,200 bpsd to 6,600 bpsd. The contract has been awarded to M/s. HUALU of China and is expected to be completed by July 2019.

Replacement of Fuel, Lube-II Refinery and Utilities Control System with centralized Distributed Control Systems
Replacement of existing control system of Fuel, Lube-II Refinery and Utilities with Distributed Control System (DCS) will ensure precise quality production, high-integrity process controls, process safeguarding and emergency shutdown. It will also improve process control and monitoring of plant parameters, availability of customized reports and log sheets, and optimum Human resource utilization. The project has already been awarded to M/s Yokogawa and is likely to be completed by June 2019.

New Sea Water Reverse Osmosis Plant
New Sea Water Reverse Osmosis plant with capacity of 250,000 US gallons per day is planned to be procured and installed following the completion of Phase-I projects to meet the increased water requirement. Project has been awarded to M/s Aquamatch of Turkey and is expected to be completed by December 2018.

101-F-1 Air Pre-Heater Project
Installation of Air Pre-Heater at fuel refinery is an energy saving and environment friendly project. Furthermore, Greenhouse gases emissions and carbon foot prints will be reduced by this project. Construction work on the project has already been started and it is expected that it will be installed and commissioned by end of September/October 2018.

COMPLETED PROJECTS

2009-10

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.

2015-16

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.

2016-17

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.

2017-18

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

Isomerization

Isomerization Unit (PENEX) and its Auxiliary Units (Naphtha Splitter and Naphtha Hydrotreater) have successfully commenced operations effective October 2017. Completion of Isomerization Unit has enabled the refinery to convert light Naphtha into Motor Gasoline which would meet the country’s requirements as well as result in fetching higher price.

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.

Turnaround of Lube-II Refinery

The Company has successfully completed the turnaround of its Lube-II refinery in November 2017.
