09:00 - 12:30
Workshop: Process infrastructure options for sulphur producers and consumers in the dynamic sulphur market

Overview
The global sulphur market is expected to continue as oversupplied in the near future resulting in a marked impact for both producers and consumers along this vital supply chain.  Oil and gas producers may be challenged to find acceptable prices for sulphur offtake and may consider pouring to block.  Sulphur consumers however, may be able to reduce feedstock costs by diversifying between liquid and solid sulphur sourcing to obtain the best possible economics. 

Workshop Content
Brief profile of world supply and demand centers for sulphur and sulfuric acid / fertilizers 
Detailed discussion on molten sulfur handling and storage tank design and construction
Process/equipment highlights for: sulphur recovery; degassing; forming and loading; blocking storage; remelters; sulphur unloading; melting and supply for sulfuric acid manufacturers 
Overview discussion of some leading technologies for SRUs and sulphur degassing, forming (50 – 10,000 tpd) and remelter (3,600 tpd in a single unit) 

All of the above will be illustrated with the help of case studies including Matrix PDM’s recent projects in China, Central Asia, North America and the Middle East to provide a global perspective.   

Who should attend?
Strategic planners and project engineers considering diversification of sulphur supply or sourcing.
Technical managers and process engineers engaged in sulphur degassing, forming, storage, materials handling and remelter operations.
Safety and environmental engineers / managers engaged in these process areas.
Sulphur logistic companies, entrepreneurs and traders considering new facilities. 

09:00 - 12:30
Workshop: Raising project capital: Maximising export credit financing for your project

Overview
In today’s fluctuating market conditions and capital constrained environment, economic viability and financing opportunities are of the utmost importance for businesses. Due to increasing competition within organizations for internal financing and in the world market for external project funding, traditional prerequisites do not necessarily lead to project realization.  Whether you are a major with a strong balance sheet or a junior developing a new site, securing project financing plays a crucial role in your overall success.

Throughout this year’s workshop, our expert in Export Credit Financing will lead you through the various possibilities to utilize Export Credit Agencies (ECA) financing to build your next project.

SNC-Lavalin will be presenting an overview on the significant role that ECA financing has played on overall project development and achievement. We will walk you through key lessons learned and case studies of how project financing has been developed for challenging projects and situations.

This workshop will:
Provide practical insight to owners and asset managers on ECA financing
Assist in developing ECA acquisition strategies
Clarify the difference between ECA loans and ECA Insurance
Review how capital services help to enhance asset management and performance

Who should attend?
Asset managers and project investors
Contract and commercial managers
Project managers and stakeholders
P/L executives

14:00 - 17:30

Debottlenecking the Kansanshi Copper Smelter sulphuric acid plant
The sulphuric acid plant at the Kansanshi Copper Smelter had been operating for less than 2 years when a study was undertaken to expand the capacity of the plant.   It was soon discovered that the acid plant was the bottleneck in the operation of the smelter.  Limits were being met in terms of maximum operating pressures, SO2 concentrations and temperatures in the plant. This paper describes the process of identifying the bottlenecks and the work done to eliminate them.

Sulphur recirculation for high-temperature corrosion and dioxin abatement in waste-to-energy boilers

Sulphur recirculation is a new technology for reducing high temperature boiler corrosion and dioxin formation in waste-to-energy plants by creating a sulphur loop. The recirculated sulphur has the benefit of producing a less corrosive environment for the superheaters. The benefits of the process have been demonstrated in a commercial installation at a waste-to-energy plant that has been operating since October 2016 where high temperature corrosion rates have been reduced by approximately 50%.
