MUG 2017
Conference Papers

Conference papers by Haverly Systems and other experts focus on new developments in planning, crude oil quality and management, refinery scheduling and product blending. Papers by clients often describe novel solutions to common and unusual problems.

Below is the preliminary agenda. More information to come. (updated 7 September)

Refinery 2040 - Changing Energy Dynamics  new
Angela Haverly, Haverly Systems
While world population is expected to grow to almost 9 billion people by 2040 with increasing economic expansion in developing nations driving the expected growth in demand for transport fuel, political and environmental concerns are quickly taking effect. With recent political movements in France and the United Kingdom to ban petroleum based vehicles by 2040, refinery economics are sure to be impacted. The question is how. Future expectations of the energy industry will be analyzed with questions posed as to how will demand for oil and gas in a global environment respond.

Molecules and Money – Crude Oil Quality Monitoring  new
Peter Spitz, AmSpec Group
Crude monitoring by gas chromatography continues to be a challenge in quality and confidence level of data. The technique of merging light ends and high temperature simulated distillation is not new but it is underutilized in production, at refineries, in planning groups, and in trading houses globally. The use of merged D7900 and D7169 is discussed as a tool to plan physical assays, to check refinery crude oil receipts and to back-cast out-turn economic yields. This gas chromatographic tool is the basis for higher quality near real time data, more precise flash assays, and executive decision confidence for liquid hydrocarbon assets. Development of confidence in its use will be discussed and examples will be shared. Additionally, new technology using VUV (vacuum ultraviolet) hydrocarbon type analysis will be presented.This is the most exciting new chromatographic detector in decades.

Creating composite yields for a Global Hydrocarbon Supply Model with GRTMPS   new
William Brown, EIA
This presentation provides a description of how GRTMPS created yields and cost variables for the conversion model of the GHSM. It will also describe types of refineries modeled, lessons learned, and preliminary results.

Project FIDELES  new
Jean Quenon, Total
Total is spending a lot of effort to build and maintain accurate refinery and petrochemical LP models. A new project was launched in 2017 by Total to review the different refinery models. Do the models comply with the corporate guidelines? Are they in line with other models? Can the users be confident in an optimal converged solution? The presentation illustrates how Total tries to answer all those questions.

What's the Deal with Octane  new
Vincent DiVita, Jacob's Consultancy
Recently, there has been heightened interest on the subject of octane, including discussions on the exceptionally wide ULR-ULP differentials, “new” factors influencing refinery octane economics, and the impact “fuels of the future” will have on octane. This presentation will review these topics and put some “LP sense” into investigating some of these relevant octane issues.

GRTMPS on a Supercomputer  new
Jean Quenon, Total; Daniel Andrews & Randy Bozarth, Haverly Systems
With assistance from Haverly Systems, Total is developing a method to solve GRTMPS planning models on a supercomputer. Taking advantage of its flexible architecture, GRTMPS has been adapted to run on Total's high-performance hardware. The goal: to solve thousands of cases in a fraction of the time without any additional burden on the user. The paper will describe the strategy, software developments, and results to-date.

Fore-Back Casting  new
Dr. Kathy Nelson, Haverly Systems Europe
When you translate your LP solution into instructions for operating the refinery, how do you identify the key targets? Does a good plan concentrate on hitting the limiting limits? Can process units that are not full and specifications that are not constraining be left to balance out to whatever values they take while we go for the important stuff? Marginal values on unit capacities and specifications are very eye-catching, and give you a sense of a dominating economic incentive, but some what-if back-casting BEFORE implementing the plan, may give a rather different picture.

Advanced Topics in H/CAMS  new
Dr. John Slaby, Haverly Systems
This presentation will give overviews of some advanced topics in H/CAMS and includes the following: A discussion on the Advanced Specifications Mode will demonstrate the ability to manipulate a non-adjacent cut as well as how to improve convergence with the multi-pass option; the GC Import feature in iCDM will be described which shows how a vendor CSV file may be imported and mapped directly into the H/CAMS set of components; finally, there will be a review of the capabilities of YieldBlend with a summary of best practices and a preview of YieldBlend 11.0.

Compatibility Check in H/Sched  new
Dr. Richard Tan, Haverly Systems
A three points crude compatibility checking technique is developed for H/Sched. This technique would test all the minimum compatibility ratio points and therefore guarantees that in each event, the crude mix will not violate the compatibility checking at any time if it passes the test.

Best Practices Using Crude Assay Data  new
Malek Masri, Haverly Systems
Production chain optimization has been always key to successful operation and to a sustainable refinery’s economy. Crude assay data and its use in planning and scheduling systems add much value to this process. Technology can now achieve much more than had ever been thought of in the past. This presentation will highlight what to look at while preparing, updating, and feeding assay data into optimization systems in several areas (laboratory, planning, marketing and scheduling). 

H/CAMS MDB Viewer  new
Dr. David Cattan, Haverly Systems
The MDB Viewer has recently been upgraded. The most notable change is the ability to filter crudes similar to H/COMET, by using properties of the assays to filter crudes. These new filtering features will be demonstrated and discussed. 

Working with Diagrams in GRTMPS  new
Eric Jwo, Haverly Systems
Haverly has been maintaining several different diagrams within the GRTMPS system. This presentation will cover the features and functionality of the block and process flow diagrams. It will also demonstrate how they are used and how they will develop in the future.. 

H/CAMS Update 
Kirby English, Haverly Systems
H/CAMS has continued to be used in many interesting ways. Haverly Systems has received a lot of good feedback in the last year which has led to some very interesting enhancements to the system. These improvements include enhanced cut spec adjustment features, new Autosmoothing routines, Output Interfaces, and Tray Efficiency modeling features to name a few. This presentation will both describe and demonstrate some of these new key enhancements.   

H/COMET Update
David Alexander, Haverly Systems
H/COMET has continued to improve significantly in all areas. The Blend Optimizer module has been improved, providing much more functionality. The Advanced Netback LP has been further enhanced with more user Interface functionality added. This paper will also discuss and demonstrate how a custom planning model can be uploaded into the system and run. This makes the system now the most powerful of its kind on the market. 

H/Sched Adaptability 
Dean Trierwiler, Haverly Systems
Haverly has found that implementing a new scheduling solution is not like “handing over the keys”, but more like “restoring a classic”. It requires blending existing elements with new to create a vehicle which is more powerful and attractive than the original, but functions in much the same way. These existing elements may be anything from resident spreadsheets for data import and special calculations, to elaborate procedures built to support a previous scheduling tool. Regardless, it is important that H/Sched adapt to these methods, rather than require different ways of doing what schedulers already know how to do. Examples of H/Sched’s adaptability will be discussed and shared in this presentation.  

Haverly Phone App 
John Nelson, Haverly Systems
Haverly has developed two phone Apps so far. One has the same functionality as the H/CAMS property calculator. The other is an assay viewing tool that links to the H/COMET database. Both will be described and demonstrated.
