PETRONAS operates a network of gas

production facilities at Malaysia Offshore

• Mercury has been discovered in the hydrocarbon stream delivered by

PETRONAS to the Gas Processing Plant (GPP) in Kerteh, Terengganu,

Malaysia• As mercury removal is becoming more challenging, there is a need to

find a more robust, new technology to reduce the content of mercury

to a much lower level.

Commercially Available Mercury

Removal Technologies (MRT)

16

• Current commercial MRT uses supported sulphides, halides and silver as active materials.

• MRT can be used to treat gas, liquid hydrocarbon and water streams

• Depending on the applications, the targeted mercury levels at MRT outlets are:

• < 0.01 mg/m3 for gas stream• < 1 mg/l for liquid stream

Current Issues with MRT:• Fluctuation in the content of mercury in the streams• Analytical Accuracy - Issues in sampling, sample

treatment and analysis • MRT’s capability to remove all types of mercury

species.• Robustness of the MRT system when other

contaminants are present in the feed

• Handling of the spent MRT materials• Hefty Unit price of current MRT materials

The IL Adsorbent Package is Innovative and Proprietary

The material has to be resistant to water vapour

The active site is a Nano-engineered by-functionalmoiety comprising a molecular scaffold andactivated metal centre.

The in volatile nature of the IL makes supportedversions robust in plant operation. This approachopens up new avenues of research anddevelopment across catalysis and contaminantsremoval processes.

Several tasks were studied in parallel primarily to reduce

risks in commercialisation and speed the development

20

A new tool to understand the “ageing profile” and screening of new

supports. High throughput experimentation tools applied and

validated.

Establish the right partnerships early. In our case with catalyst

manufacturers, support providers, ionic liquid manufacturer.

Strong support from site for implementation – commitment through

the organisation

Economics, commercialisation, corrosion, risk management, HSE, Due

Diligence, Patents & IP.

Critical path issues managed by central team drawn together from

manufacturing, technology, engineering and business development.

Key to success was “excellence” in project management. The

difference between success and failure.

Mercury Capture Profile of SSILs

21

The team developed a new tool to predict the commercial lifetime of new

supports.

The mercury captured by the SSILsapproach 70-75% of the theoreticalcapacity based on the oxidation tomercury(II) and incorporation intothe ionic liquid structure.

Laboratory results indicated betterperformance in terms of mercuryuptake as compared to commercialadsorbents.

Selection of the optimal ionic liquidcompositions and optimal supportfor the next stage pilotdemonstration.

Slip stream pilot plant

22

The heart of the slip stream pilot plant ismultiple reactors fed direct from the mainplant gas feed.

The unit is set-up for “doping extra Hg” toallow adsorption capacity to be estimated(life of the adsorbent).

The unit sees all plant operational variancesand feed gas changes in the main plant.

Multiple beds allows comparison of differentadsorbents

Additional capability and understandinggenerated on site. Early opportunity fortraining on new technology.

It is possible to fast track R&D commercialization. It needs:

1. The “right project” – strategic fit to Company objectives

2. The right partners: catalyst manufacturer; support supplier, fundamental

support, in-house expertise and excellence (eg Petronas Hg analysis)

3. Commitment from industrial partner especially site management and personnel

3. TEAMWORK and FOCUS

Development of membrane contactor pilot systemThe commissioning for pilot scale hollow fiber membrane contactor on CO2 removal from natural gas was

successfully conducted in a gas process plant located at Malaysia east coast, which is jointly developed by Prof. Cao Group (DNL0905) of Dalian Institute of Chemical Physics CAS (DICP) and PETRONAS.

The system operated continuously and stably for 72 hours, the results indicated that all process parameters met the contract requirements. It is the world`s first system to purify the high pressure natural gas by hollow fiber membrane contactor. The unit adopted firstly the PTFE hollow fiber high-pressure membrane absorber jointly developed by DICP and Shanghai Bi Ke Clean Energy Technology Co., Ltd (“CECC”), the performance indicators of which also satisfied the contract requirements for the membrane development.

Factory Acceptance test: inlet 10 %, outlet <0.1 %

GPP3 on-site test: inlet 5%,outlet 0.02%-0.2%

Development of membrane contactor pilot system

The MBC system integrates the advantages of membrane separation technology and traditional adsorption process and is proved to be low energy consumption, high separation efficiency, high recovery rate of natural gas, compact device with small footprint, operation friendly, and other superior properties. The innovative technology can be used not only for acidic gas removal from natural gas (especially on offshore platform), but also for other areas like biogas purification and CO2 capture of flue gases.

Reduction & Savings

--- Data by Aker Process System

• Capex reduction of 35-40% due to smaller equipment, Smaller footprint

(floating LNG is possible)

• Opex savings between 30-40% due to Lower energy requirement for

regeneration, higher pressure operation (less compression

required),Minimal hydrocarbon losses, Reduced foaming

Reduction & Savings

--- Data by WP

Conclusions

• Despite falling oil prices and uncertainties in the short

term, innovations and improvements to our daily

operations are key for stability and safe, economic

operations

• Gas is proving to be a feedstock of choice for power

and is resilient in the market place with LNG markets

remaining strong and durable in the current crisis

• With remote gas, FLNG production is proving a

useful vehicle for marginal fields.

• The larger gas complexes (e.g. shale) are now taking

advantage of novel gas conversion opportunities.36
