Amine experts training course

The amine treating training course presented by Amine Experts is internationally renowned for the practical knowledge that it imparts to attendees. More than 300 courses have been presented worldwide, from which 7000 engineers and operators have benefited.  The course will last one day and provides attendees with an understanding of the pivotal aspects of amine treating.
 
The Amine Treating course is a shortened version of the in-depth 5-day training that is offered annually in Canada, Asia, USA and Europe and will cover the following key topics:

1) The Principals of Amine Treating
2) Optimal Operating Conditions
3) Foaming and Solvent Losses
4) Heat Stable Salts and Degradation
5) Corrosions Mechanisms in Amine Systems
6) Reasons for Amine System Failure
7) Calculations

The goal of the course will be to orient attendees to amine systems, impart the knowledge needed to avoid common mistakes and equip them with the tools for basic field troubleshooting.

The course will be presented by Philip le Grange. Working for Amine Experts, Philip has performed troubleshooting, optimizing, commissioning and training worked on more than 50 amine systems across 23 countries. He has been in the oil and gas industry for 10 years and prior to consulting has worked in both Operating Engineer and Plant Designer roles for chemical solvent systems.

Please note the workshop is separately bookable at a cost of $795 per delegate

Sulphur recovery workshop

Workshop Overview
In sour gas processing, the sulphur plant itself is highly inter-dependent on upstream and downstream gas processing units such as acid gas removal (AGR) and enrichment (AGE), tail gas treating (TGT), and sour water stripping (SWS).  Experimenting with full-size production plants to improve understanding of process behaviour can be a career limiting learning process.  However, process simulators have become increasingly realistic.  With the availability of mass transfer rate based simulation of gas processing, and the recent introduction of a first principles based sulphur plant simulator, it is now possible to convert an entire gas treatment facility into a virtual plant.  Today, simulation allows real understanding to be gained by doing precisely what cannot be done in the plant—experimentation.  The workshop is designed to dissect and understand several broad aspects of modern sulphur recovery.

Workshop Objectives
The workshop is designed to help you gain more in-depth understanding of Claus-type SRUs and improve their performance through:
Studying feed preparation techniques in controlling H2S quality, hydrocarbons and NH3 content,
Controlling combustion air and understand the importance of the air demand analyser,
Evaluating how tail gas clean-up directly affects SRU performance, and 
Understanding the kinetics of thermal reactions in the furnace and WHB, optimising catalytic converters, sizing and rating sulphur condensers, and dealing with sulphur storage, handing and degassing.

Who Should Attend
The workshop is intended for
Engineers relatively new to gas treating and sulphur recovery
Technical managers and engineers engaged in plant design, production, troubleshooting and revamps of process units in acid gas removal and sulphur production
Process equipment suppliers, particularly of towers used in gas treating and catalyst vendors

Workshop Contents
A one-half day, hands-on workshop using process simulation software and covering the topics:
Thermal Reaction: contaminant destruction (NH3, BTEX, hydrocarbons); the evil step cousins – CS2, COS, and trace sulphur; oxygen enrichment; Waste Heat Boiler recombination reactions and heat flux implications
Sulphur Condensers: equipment design & rating; H2S/H2SX/SO2 solubility; entrainment
Catalytic Conversion: optimal operating temperature; catalyst selection; COS/CS2 conversion vs. Claus reaction; modelling SOR vs. EOR conditions
Sulphur Storage, Handling, and Degassing: sulphur viscosity, product quality, H2S degassing 
Tail Gas Clean-up: effect of NH3 and SO2 on quench column and amine system performance;        EOR design and operation considerations
A limited number of laptop computers will be provided, restricting the hands-on aspect of the workshop to a maximum of 20 participants.  If you wish to use your own computer, an evaluation copy of ProTreat? software must be installed before the workshop—please contact conferences@crugroup.com before the workshop to arrange this.

14:00 - 17:30
SRU Burner workshop

Workshop overview
In this workshop we will focus in on the burners in the sulphur recovery unit (SRU). We will discuss the key aspects with regard to the design and operation of the SRU main and incinerator burners. Specific attention during this training will be given to the refractory design and pyrometers, since high processing temperatures play a critical role in these combustion sections.

This training will have a practical approach and is mainly intended for plant operators and other disciplines who are frequently involved in the operation of SRU’s.

Sour gas fields in the Caspian Region: selection the design of development
There is a number of huge oil and gas fields containing hydrogen sulfide in the Caspian Region. These are Astrakhan, Karachaganak, Tengiz and Kashagan in the Northern Caspian, where the gas is contained in the Paleozoic deposits. In the Middle Caspian oil and gas fields have been discovered in the Caspian sea and adjacent land areas to the West and East in the Upper Jurassic sediments. Excess sulfur production leads to the necessity of choosing other options for field development without the sulphur recovery. Reinjected acid gas after separation from the condensate and hydrocarbon gases may become an alternative to the standard approach in the development of these fields. Geological and technological problems are discussed.

14:15 - 14:45
Acid gas enrichment – new wrinkles on an old process
Sour gases containing low concentrations of H2S can be particularly troublesome and costly to process in conventional sulphur recovery units (SRUs). Unlike refineries, which routinely operate with 70-90% or higher H2S in the acid gas feeds, sulphur plants in natural gas service often see much lower H2S concentrations. A myriad of problems have been reported through the years with lower H2S feeds, some of which include flame stability and the associated susceptibility of the SRU to contaminants (NH3, hydrocarbons, BTEX) which can lead to operability and reliability concerns, increased operating cost (feed preheat, oxygen enrichment, natural gas co-firing), and difficulty in design.

The technique of “enriching” the acid gas, or Acid Gas Enrichment (AGE), overcomes some of these problems, usually at the expense of additional operating equipment and complexity. However, there are innovative plant line-ups which can leverage AGE benefits, while also optimizing capital expenditure and operating costs.  Unique AGE configurations can be utilized to achieve economical, robust operation in grassroots facilities, or can be employed in existing facilities that are required to meet new, lower SO2 regulations.    

In this work, we briefly review the more common AGE configurations and also more closely examine several unique AGE line-ups from a techno-economic perspective. By understanding  the basic operating parameters that affect selectivity through mass transfer rate-based simulation, several selectivity improvement opportunities that have been previously unpublished are evaluated. One of the techniques evaluated can be applied to existing operating plants without additional capital.

Options screening drives innovation for Shell's upstream gas processing technology portfolio
Most mega sour projects are built on a lump-sum EPC basis, this paper highlights the importance of providing a sound engineering basis during the Pre-FEED/FEED phase, thereby providing cost effective alternatives and shorter schedules of the project without compromising on the quality, safety, reliability of mega sour gas processing facilities.

This paper highlights the importance of technology evaluation at early stages, how to approach designing large sour gas projects and the benefit to clients from consultancy knowledge and expertise on designing mega sour gas processing plants.

Petrofac was invited by SGS to provide an industry view for design line up for sour gas processing facilities. This study was focused on identifying solutions by Petrofac to understand an external viewpoint of technology deployed for sour gas processing.

This study explored various process line-up’s and the intent was to deploy the right technology for the given application (cases) not only those that are technically quite challenging but also what is normally considered as a standard line- up for sour gas processing plants.

Gaining a clear insight of the process line-up’s available and the relative value that each generates is the heart at solving this problem, however not all options are same.

The challenge to address the cost of sour gas project development is an on-going effort and Petrofac has been at the forefront of cost reduction and implementing these projects that makes Petrofac a leader in the sour gas processing arena.

Petrofac provided SGS the recommendation of the study which has added value to Shell’s Upstream gas processing technology portfolio and has been deployed for its future technology development, specifically the latest Shell ADIP-Ultra technology.

Systemic approach to improving amine fluid quality: A case study
Contamination in amine treating systems is endemic in the industry, and unless properly managed can affect treating capacities, operating costs and equipment reliability.  Typical contaminants include hydrocarbon aerosols entering the systems with the sour gas, hydrocarbon build up within the recirculating amine system, particulate contamination entering and being formed in the amine system, and amine degradation products.  

A large US Gulf coast refinery tail gas unit was faced with very high filtration change-out frequency on their rich amine system.  Effective determination of particulate contamination in a rich amine system is complicated by the propensity of the rich amine to oxidize in the presence of air, thereby making off-line bottle-sample analyses unreliable.  A suitable analytical technique was used to obtain reliable particle sampling of the rich amine system.  Following extensive analytical work, a number of different separation media configurations were evaluated resulting in an 8-15 fold reduction in change-out frequency, and an approximately 70% reduction in operating cost, while improving the fluid quality of the amine system.  By the end, the particulate contamination in the recirculating amine had declined from 4-8 mg/lit to non-detectable.  

The presentation will discuss the analytical techniques used, as well as the systematic testing program undertaken, along with a best-practices finding.

Preventing hydrocarbon carryover into the sulphur plant
It is understood the sulfur plant is a necessary component in refinery operations with a sour crude slate.  The sulfur plant enables the refinery to sell a sulfur and reduce emissions to comply with national, state and local regulations.. Hydrocarbons, such as methanol, BTEX and others have different flash points and BTU values other than the normal fuel gas. The burner in the sulfur plant requires a certain BTU range in order to burn efficiently. Poor burning of the acid gas can result in the emissions going off spec. Also, the sulfur produced from the sulfur plant must meet a color spectrum specification in order to be sold at market prices. Hydrocarbon discolors that as well and will reduce the market price of the sulfur. Thus hydrocarbon carryover into the sulfur plant becomes a serious concern. The source of the hydrocarbon carryover is almost exclusively from the amine treater. The sour water stripper mostly provides the sour gas and carries very little hydrcarbon to the sulfur plant

 Since amine is derived from hydrocarbon, amine also has a high affinity for absorbing hydrocarbons. The hydrocarbon that accumulates within amine treatment plants depend on the feed stock and how the amine system is configured in the flow scheme of the refinery. In our experience there could be lubrication oils from compressors, methanol from upstream processes and also included are light hydrocarbons, BTEX, and paraffins all coming from the gas feed.

The hydrocarbons that end up accumulating in the amine treater cause all sorts of interesting problems

Hydrocarbons cause foaming, burping and other upset conditions in the amine treater. The upset condition in the amine plant consequently causes amine and its absorbed hydrocarbon to be whisked away with the sour gas stream from the top of the regeneration tower in the amine system.  Hydrocarbon in the amine system is bad for the sulfur plant and the amine plant.
