  ADNOC to host the worlds leading Gas Sweetening Event
 

Next month will see the leading international experts gathering in Abu Dhabi at SOGAT 2014 to debate the latest technologies used in converting Sour Gas into sweet gas that is required for usage throughout the UAE and the Gulf region generally to support the ongoing infrastructure, power and petrochemical requirements. This event is one of the world’s best known oil & gas processing eventsand is celebrating its 10th anniversary. This year there will be Workshops on the lessons learned from

sulphur plant operations, amine treatment, process optimization, gas compression, the sulphur supply chain and the key aspects of contamination removal. The latter workshop is one of the key themes of the event as a whole with new exhibitors from China complimenting the major international process separation companies in the SOGAT Exhibition. Other new exhibitors will be showing their expertise with process simulation tools for designing complicated refineries and gas processing plants. This exhibition is free to attend and pre- registration at www.sogat.org is required.

The SOGAT conference will be opened by Khalid Sahouh, Senior Vice President of ADCO. Some 30 papers will be presented on all major areas of Sour Oil and Gas Technology innovations and developments, at a time when the BAB ultra sour field development is beginning, as ADNOC and Shell form a company to commence its exploration and production. Another important aspect of the Conference will be the presentation from the Qatari Ministry of Energy & Industry on their Carbon Capture plans and it will focus on the Dukhan Jaleha EOR Pilot project. This presentation is very timely for the region given the recent agreement between ADNOC and Masdar on similar plans for UAE.

 
 
  UOP, Qatar Petroleum to jointly develop new gas treatment technology
 

Honeywell's UOP announced Tuesday that it signed a joint development agreement with Qatar Petroleum (QP) to develop new ways to cost effectively treat natural gas for the production of LNG.

Under the agreement, the two companies will work together to develop more efficient technologies to remove contaminants from natural gas, so that it can be liquefied for transportation by ship and other

means.

The agreement was signed at QP headquarters by Dr. Mohammed bin Saleh Al-Sada, Minister of Energy and Industry and chairman of QP, and UOP president and CEO Dr. Rajeev Gautam.

Dr. Al-Sada said the agreement is an important milestone in Qatar’s gas industry.

“Qatar is constantly working to facilitate the optimum development of its hydrocarbon resources, and this agreement is another step in that direction,” said Dr. Al-Sada. “Developing more efficient technologies to remove contaminants from natural gas will help boost Qatar’s reputation as a safe, reliable supplier of natural gas as well as high-quality products.”

UOP is a leader in natural gas treating technologies, which are currently used in QP’s LNG and gas processing facilities. QP’s joint venture companies, Qatargas and RasGas, have a combined LNG production capacity of 77 million tpy, making Qatar the world’s largest producer and exporter of LNG.

“Global natural gas demand is growing rapidly and LNG production is critical to meeting the needs of regions not served by pipelines and to enable global trade," said Dr. Gautam. "Qatar Petroleum is a recognized leader in the production of LNG for world markets, and we look forward to extending our long-standing partnership to develop technology in this important field.”

UOP’s separation technology and equipment remove contaminants such as sulfur, water and carbon dioxide from natural gas in order to meet rigorous product specifications and requirements for downstream transmission and liquefaction equipment. In liquefied form, natural gas can be easily and efficiently transported to markets around the world, where it is used for a wide variety of energy applications.

 
 
  New Phases of South Pars to Come Online in Two Months
 

Gas production from the South Pars gas field will rise in the next two months by at least 37 mcm/d, managing director of Pars Oil and Gas Company (POGC) Ali Akbar Shabanpour said. Shabanpour said the company tries to bring online 12 mcm/d of gas from the first train of South Pars gas field phase 12 in less than two months adding platform A of the phase is ready now for pumping sour gas.

He added that the first train of the phase in onshore sector is in pre-commissioning and commissioning stage while its utilities including water, power and steam units have already come online.

According to Shabanpour, POGC also plans to launch both trains of phases 15&16 before the end of current Iranian calendar year in March 2014 which will yield 25 mcm/d of gas in total.

Shabanpour said that South Pars phases have been divided into two groups. The first group includes prioritized phases with more than 90 percent physical progress including phases 12 and 15 to 18 and the second group includes phases 11, 13, 14, 19&20 to 24.

 
 
  STX Heavy Industries wins $99.5m Iraq deal
 

Korean engineering company STX Heavy Industries has announced its second major contract win in Iraq in as many weeks after picking up a $99.5m deal to build a new gas treatment facility.

The unit will be built at the Garraf Oil Field for the joint venture working on the field, Petronas Carigali Iraq Holding (PCIHBV).

STX said that the project is expected to run for 24 months and be complete by the end of November 2015.

Earlier this month, the company announced that it had secured a $449m order to build a 550km pipeline in the Akkas Gas field. That deal was awarded by Kogas Akkas, which is a unit of Korea Gas Corp and will complete by June 2017.

 
 
  New Sour Gas Corrosion Inhibitor Compatible with Kinetic Hydrate Inhibitor
  At the IPTC Conference in Doha this week a paper from Baker Hughes was presented on this subject.The presence of hydrogen sulfide in high pressure gas systems causes several complications. Sour gas corrosion is a major concern in the oil and gas industry due to the presence of localized corrosion. At high pressures and low temperatures hydrates can occur. Sour gas decreases the pressure and increases the temperature at which hydrate formation occurs.

Operators have used both corrosion inhibitors and kinetic hydrate inhibitors to decrease the capital requirements of developing sour high pressure gas systems. The development of sour gas corrosion inhibitors that are compatible with kinetic hydrate inhibitors is a major requirement for qualifying corrosion inhibitors for these applications.

The paper describes laboratory work on the development of a new corrosion inhibitor by performing various performance and compatibility tests with kinetic hydrate inhibitor. The new corrosion inhibitor needed to meet various additional requirements which made the development process even more complex. The partitioning of a corrosion inhibitor between the oil and water phases has a significant impact on inhibitor selection and treatment strategy. General corrosion performance was addressed using mass loss and electrochemical data. Evaluation of localized attack was performed using vertical scanning interferometry (VSI). The main advantage of this approach is in providing quantitative data for product performance differentiation in the presence of localized corrosion.

 
 
  A tangled web in the Caspian
  The giant Kazakh oilfield Kashagan, which was brought to a halt by leaks shortly after startup last year, is grappling with a bureaucratic “nightmare” on top of its engineering troubles as it strives for commercial production this year. In October last year, pipeline leaks that investigators think were caused by H2S- linked stress crackss led to shutdown.
 

According to a statement last month, tests carried out on parts of the pipe by TWI Laboratories in Cambridge, England, found the cracks were caused by a reaction between water and H2S, which is known in the industry as sour gas.

Why this reaction caused the pipe to crack remains unclear, with one expert saying the search for the reason – and a solution – was like “finding a needle in a haystack”.

The leaks, in the onshore section of a 95km pipeline taking gas ashore for processing, have caused some to question the quality specification of the pipes, given the high H2S content. A spokesman for NCOC said the pipeline was “aligned with the X60 specification”, a reference to a grade of pipe that tends to be carbon steel but can also be alloy. The spokesman said the X60 grade pipes were dealing with associated gas containing approximately 15 per cent of H2S and were designed to withstand concentrations of 12 to 15 per cent.

“The pipeline design basis has very recently been confirmed by experts, and it would have been designed in exactly the same way if it had been built today,” the spokesman said.

A source with secondary knowledge of the investigation said the consortium was looking at whether the pipes were up to the job and whether costlier grades should have been fitted.

 
 
  The UAE runs its first freight train
  The first phase of the National Rail Network was developed in cooperation between Union Railway and ADNOC. With a length of 264 km, it links the Habshan and Shah fields to the Ruwais port for transporting about 3.6 million tons per year of GASCO’s sulphur granules.

The Railway will contribute to enhancing GASCO’s sulphur production. Transporting sulphur by train is more efficient and much safer than transporting it in liquid form.

GASCO recently built two stations along the train’s route to efficiently unload sulphur granules.

Available in the port area in the Western region are currently 7 locomotives and 240 carriages for effectively and safely transporting sulfur. Each train will consist of 3 locomotives and 110 carriages, with a maximum speed of 120 km per hour and a load capacity of 11 tons of sulfur per trip.
