Dear Editor

This letter I am writing to you as a Pakistani and professional Chemical Engineer who has experience of more than 17 years in Fertilizers, Oil & Gas and Petrochemicals in Pakistan and abroad. I am providing consulting services to Oil & Gas and other industries in Pakistan.

You are aware of Thar Project of Underground coal gasification led by Dr. Samar Mubarak and his team. We would like to highlight serious concerns on this project which lead to Pakistan in depriving of these assets without harnessing the huge energy and petrochemical potential for our country which is dependent on the success of this pilot project. You can imagine if any pilot project fails only due to lack of knowledge and expertise what can happen!

This is going on here in this project and they want to make this project a failure so no other company will invest and get the true benefits for this nation. We request you to bring this issue in front of the nation and stop them to play with the resources and money of peoples of Pakistan.

They are working against the principles of common understanding, logical approach, engineering or whatever you name it. If you talk to any Oil & gas company how they build the gas and oil processing facility, they will tell you that they first do rigorous tests on oil and gas wells to characterize the gas and oil composition and then built the facility which is going to be multimillion dollar facility. This is the very first step but in UCG they do not know anything what is coming out of the gas and they want to built a facility there and spend lot of money and then they say the pilot was not successful.

UCG Thar coal project invited bids in February 2011 for supply of Gas dehydration facility and there are lot of technical flaws in their concept paper which they call it Invitation to bid. We participated in the bid with our Technology cooperation partners from abroad and submit a proposal based on their scheme with a statement that it is not going to work. At the same time we propose the phase wise approach which we call it GATE approach which proven in the industry for the project execution. We made a presentation to them Dr Shabbir at their offices in Karachi in April 2011 and propose a scheme that we start with the test separator and after analyzing and characterization of gas we will start designing the facility.

They don’t want to listen this scheme. We said ok. Allah has give us fortune but our so called Politicize Technocrats made us unfortunate.

In September 2011 they have re-invited the bids again with a 180 degree change in their OWN design which relatively better than the previous. At this time we decided we go with the Client Scheme and make necessary changes so that the plant can run and make this pilot successful.

There were three competitors, two Pakistanis and one Chinese. Chinese quoted a price of 3.8 million dollars which is impossible and Dr. Samar Mubarak has understanding with the Chinese company. We are asking UCG Management as Engineers we should know what they have offered and how it is possible. We have worked on the bid for two months day and night and contacted each and every vendor in China and other parts of the world and we are surprised and shocked to hear this price.

This is a 20000 Nm3/hr plant which is around 18 MMSCFD and you can ask a price of natural gas processing plant which has a cost of around 20 million USD.

Here is not a question of bid or getting business, our argument is UCG should let us know how they are going to achieve this with the Chinese offer which we believe is not possible altogether.

We are worried and have a genuine concern as a Pakistani that if this UCG pilot fails no body is going to explore and harness the potential of Thar for Pakistan at-least in near future and keep Pakistan in growing darkness

We cannot let them go like this!

Here few technical arguments

1. Cooling Requirements of raw feed gas
Ask them at what temperature the Chinese are feeding gas to Desulphurization plant. As per UCG Client scheme they mentioned cooling of gas to 80 deg C and feed to desulphurization plant. This is not possible because all desulphurization plants need gas at 40 deg C.
To achieve this temperature you need chilled water and large air coolers which are expensive equipments

2. Plant safety
This is a real hazardous plant containing explosive and toxic gases. To ensure the safety of plant you need to have proper automatic isolation and depressurizing system and this is based on Engineering and not just supply of few equipments. Chinese has the worst safety records in Process plant safety. Hydrogen sulfide the most lethal gas above 10ppm can lead to fatality. If the plant is not properly designed as per standards and codes you are playing with the life of plant personnel which of course be Pakistani.
Hydrogen again is the most explosive gas and even a friction can lead to hydrogen bomb explosion.

All isolation and control valves only cost a million dollar. Without proper safety isolation and trips they are going to explode the plant. Ask them are they going to operate the plant only for day to pass the gas through the equipments and don’t know where they take the gas. They have not considered even the life line of plant which is the flare header or vents. They are playing with the lives of people in that area. Without shutdown system they cannot even stop the feeding gas to the plant.

Please tell them not to play with the future of Pakistan and peoples money.

3. Size of the plant and cost
They are talking about 20,000 Nm3/hr (18 MMSCFD) and inlet gas header is around 30 inch. You know the metallurgy requirement more than us for hydrogen and H2S environment. It is a reasonably sized plant and not the testing facility. Check any natural gas sweetening and dehydration plant even from the china they cannot get even less than 20 million USD of same capacity.

4. Pilot testing
You know for the pilot projects you go with the best equipment and people to make it happen. You don’t do any optimization and the value engineering at the piloting stage. If it goes wrong and failed the project may stop and it seems UCG want to do this and we do not let them do like this.
Imagine the test flights for new airplanes and jets, you choose the best pilot to make the test flight successful and spends lot of money. With all due respect and sorry to say here in UCG people who don’t know anything of the gas plant are going to monkey with the project.

To investigate inquiry commission should be formed for third party technical evaluation
