Sulphur 2017 meets in Atlanta

Summary

Now in its 33rd year, Sulphur 2017, CRU's premier industry event for the sulphur and sulphuric acid industries, will take place on 6-9 November 2017 at the Hilton Atlanta hotel in Atlanta USA. In this preview we highlight the events and some of the key topics in this year's programme.

Abstract

Regularly attracting over 550 delegates from around the globe, representing sulphur and sulphuric acid producers, operators, consumers, technology and engineering suppliers and service providers from across a range of industries, the Sulphur Conference and its exhibition of 60+ exhibitors offers the opportunity to meet, learn and network. The extensive programme includes pre-conference workshops, commercial sessions covering key market trends, project updates and supply and demand forecasts and a two-day split stream technical programme showcasing the latest technological developments. Keywords: Sulphur 2017, conference, exhibition, preview, workshops, Atlanta, programme, commercial programme, technical programme.

Innovative wet ESP designs

Summary

Modern gas cleaning and emission control strategies continue to evolve in response to the increasing complexity, toxicity and corrosiveness of industrial exhaust and process gases, not to mention increasingly stringent environmental regulations. In this article we track the commercial progress made during the last decades in the development of high performance wet electrostatic precipitator solutions to replace aging wet ESP models with all-lead internals.

Abstract

Metallurgical sulphuric acid plants are commonplace in non-ferrous metallurgical operations, providing a means of recovering sulphuric acid and preventing sulphur dioxide (SO2) emissions. In non-metallurgical applications, such as petroleum refining where sulphuric acid is utilised as a catalyst, regenerating spent sulphuric acid is also common. In both of these applications, wet electrostatic precipitators (wet ESPs) are an important step in ensuring high-efficiency reduction of dust, fume, and sulphuric acid mist in order to optimise sulphuric acid quality. Keywords: gas cleaning, metallurgical sulphuric acid plants, non-ferrous metal plants, smelter, wet electrostatic precipitator, wet ESP, emissions, gas impurities, sulphuric acid product quality, dust control, materials of construction, lead, alloy, FRP, composite material, tube bundle, gas distribution, insulator hood, Editube, Edirod, Southern Environmental, B&W MEGTEC, Beltran, Outotec.

From low cost by-product to premium AS granules

Summary

thyssenkrupp Industrial Solutions (tkIS) has developed a new fluidised bed granulation process to convert low cost by-product ammonium sulphate solutions into premium grade granules. Jens Mathiak of tkIS, describes the process and reports on the current status of the technology.

Abstract

High-quality fertilizer for optimum plant growth Plant growth depends on the nutrient content of the soil. A balanced distribution of primary and secondary nutrients as well as microorganisms ensures an optimum crop yield. Nitrogen is an essential nutrient, and so is sulphur. Keywords: fluidised bed granulation, ammonium sulphate, AS, granules, crystalline, fertilizer, ammonium sulphate prices, premium product, by-product, thyssenkrupp Industrial Solutions, tkIS.

Sulphur recovery trends

Summary

Sulphur projects around the globe face numerous design challenges to increase sulphur recovery efficiencies, reduce SO2 stack emissions and deliver fast track schedules. Over the following pages we report on recent projects by Jacobs, Siirtec Nigi and Amec Foster Wheeler.

Abstract

JACOBS World class recovery at SAMREF with EUROCLAUS® upgrade M. van Son and R. van Grinsven (Jacobs Comprimo® Sulfur Solutions) and K.S. Ghazal (SAMREF) SAMREF(Saudi Aramco ExxonMobil Refinery) recently completed the design and successful start-up of their newly retrofitted EUROCLAUS® unit. Jacobs provided the required engineering, inspection, pre-commissioning, start-up and performance test support. This article reports on the development of the project and how the project resulted in the highest confirmed overall sulphur recovery efficiency (SRE) from a facility with ­EUROCLAUS® technology. Keywords: sulphur projects, SO2 stack emissions, SO2 emissions, fast track, Siirtec Nigi, Jacobs, Amec Foster Wheeler, EUROCLAUS, Advanced Burner Control, ABC, Jurassic production facilities, North Kuwait, Latin America, sulphur recovery, Sabriya, HCR, start up, performance testing.

Improving emissions for a cleaner environment

Summary

M. Rameshni and S. Santo of Rameshni & Associates Technology & Engineering (RATE) report on a new zero emission tail gas process for sulphur recovery facilities. RATE's Super Enhanced Tail Gas Recovery (SETR) process can be added to any Claus process or tail gas treating unit after the incinerator and before the stack. It has lower capital and operating costs than a caustic scrubber, requires no chemicals and produces no waste stream.

Abstract

Since its inception in 2011, Rameshni & Associates Technology & Engineering (RATE) has executed numerous projects around the world in sulphur recovery and gas treating. At the same time RATE has also been working hard to develop new technologies related to sulphur technologies, gas treating and overall total sulphur management to improve emissions for a better future and a cleaner environment. One of these developments is the RATE patented process scheme for super enhanced tail gas recovery (SETR), a zero emission tail gas process designed to achieve less than 10 ppmv of SO2 from the stack. Keywords: Super Enhanced Tail Gas Recovery, SETR, RATE, zero emission, tail gas, sulphur recovery, incinerator, stack, caustic scrubber, caustic scrubbing, selective oxidation catalyst, direct oxidation, SMAX, SMAXB.

Central Asia's sulphur surplus

Summary

While a full re-start at Kashagan remains elusive, continuing oil and gas developments around the Caspian Sea seem set to produce more volumes of sulphur in the coming years, but can this sulphur find a market?

Abstract

The central Asian region is home to considerable reserves of oil and gas, much of it sour. As global demand for oil and gas continues to increase, so has oil and gas processing within the region, and consequently large volumes of sulphur are also recovered. However, the region’s relative inaccessibility means that the prospects for exporting oil, gas and indeed sulphur depend very much on logistical concerns and prevailing oil and gas (and sulphur) prices. Keywords: KASHAGAN, KAZAKHSTAN, UZBEKISTAN, AZERBAIJAN, RUSSIA, ASTRAKHAN, SHAH DENIZ, TENGIZ, TCO, NCOC, IRAN, YOLOTAN, GALKYNYSH, LOGISTICS, REINJECTION, RE-INJECTION, RE-INJECT, SOUR, ACID

Sour gas potential

Summary

As recovered sulphur from sour gas continues to boost the global sulphur supply, how much more sour gas remains unexploited?

Abstract

Last issue (Sulphur 371, Jul/Aug 2017) we looked at the current state of development of various sour gas projects around the world, which are continuing to increase the levels of recovered sulphur, especially in places such as China, Central Asia and the Arabian Gulf.

North American refining

Summary

US refiners are now some of the largest exporters of finished products, but changing feedstock slates, Canadian oil sands production, a revival of Mexican capacity and the prospects of US oil exports as well as the global demand situation may all have a bearing on future North American refined sulphur output.

Abstract

The US oil and petrochemical industry continues to be transformed as a result of the tight oil boom, but the way that this has played out over the past couple of years has changed for a variety of reasons. One significant factor has been the fall in oil prices that began at the end of 2014. Keywords: SHALE, TIGHT, PADD, SYNCRUDE, DILBIT, IMO, ECA, CRUDE, REFINE, REFINERY, REFINERIES
