Pentair Thermal Management – Stand 61

Pentair Thermal Management, formerly known as Tyco Thermal Controls, is the world’s largest provider of complete heat management systems for industrial, commercial and residential markets. At Sulphur 2013 they will showcase their long line skin effect heat tracing (STS) technology.

The new millennium has seen a rapid global focus on the discovery of new energy sources, with an ever growing dependency on heavier crudes. The introduction of these new energy sources has resulted in a number of new byproducts that require special attention for their off site transportation needs. Complying with the world’s expanded focus on safety and reliability and the increased concern for environmental protection requirements have resulted in an increased dependency on liquid sulfur transportation using heated and insulated cross country pipelines.

The use of STS has resulted in an increased efficiency of providing the heat input needed to compensate for the heat lost to the environment. The latest developments in thermal insulation include an increased awareness of the advantages of prefabricated and preinsulated piping which have contributed to delivering a more homogenous thermal profile while fiber optic based distributed temperature sensing has had a tremendous impact on the control and monitoring of the pipeline temperature.

The increased emphasis on the integrated sulfur pipeline approach along with the bundling of state of the art technologies has significantly improved the safety and reliability of these pipelines which serves to increase the efficiency and predictability of the remelting of solidified sulfur. This leads to the improvement of preventive maintenance programs, resulting in a reduction in down time and a lower cost of ownership.

Shell Cansolv – Stand 7

Shell Cansolv delivers state of the art gas absorption solutions that can remove CO₂ and SO₂ from a broad range of industrial flue gases. Shell Cansolv’s SO₂ and CO₂ technologies can be used across a wide variety of industries including oil and gas, power generation (including coal fired power plants and combined cycle natural gas power plants), metallurgical applications, chemicals, industrial boilers and sulfuric acid plants. The highly adaptable technology can be added to an existing plant or incorporated in a new installation.

• SO₂: The CANSOLV SO₂ scrubbing system is an efficient, proven and effective solution for post combustion absorption of SO₂ from flue gases.
• CO₂: Shell Cansolv is a leader in deploying post combustion CO₂ capture technology at commercial scale.
• TGT+: The CANSOLV TGT+ (Tail Gas Treating Plus) process can help to achieve the most stringent emission standards at a competitive cost while minimising complexity. The process also provides an outlet for disulfide oils and other off gases.
• Integrated SO₂/CO₂: Shell Cansolv’s integrated SO₂/CO₂ technology provides a simplified single source solution to meet SO₂ and CO₂scrubbing needs.

Shell Cansolv’s technologies use regenerable amines to remove SO₂ and CO₂. These regenerable solvents make the processes more cost effective and also minimise environmental waste.

Parker Twin Filter – Stand 9

Parker Twin Filter is one of the world leaders in filtration equipment and consumables for air, gas and liquid filtration. Parker Twin Filter have a strong focus on quality, environment and working conditions and therefore received the highly recommended ISO 9001 and 14001 certificate.

Parker Twin Filter understand the difficulties in sulfur burner plants and its filtration processes. The filtration of liquid sulfur is required, the removal of solids reduces maintenance costs and improves the operation of the burners.

Liquid sulfur (primary) filters

The Twin Filter liquid sulfur filter is one of the most suited filters for sulfur filtration. It is a horizontal filter tank with vertically positioned filter plates.

The tank is fully steam jacketed on the sides, dish heads cover closure and all nozzle connections. Filters are normally of carbon steel construction. The filter is equipped with a bajonet closure, hydraulically operated. The standard design includes a heated closure flange to prevent solidification of sulfur on the sealing surfaces. The three part quick opening closure is provided with safety devices that have to be unlocked before opening the filter.

No disconnection of piping Twin Filter offers systems with fixed piping which offers the best safety and operating conditions for the operators.

Advantages:

• Filter plates stay stationary at all time, retractable shell.
• No disconnection of piping during cleaning.
• No moving parts above the filter plates when the filter is opened
• In case of a power failure the tank can be manually retracted.

Polishing filters for liquid sulfur filtration

Polishing filters used to filter liquid sulfur are vertical vessels equipped with filter cartridges and are positioned in series with the primary filters.

By installing these polishing filters in series with the primary filters, the apparent benefits are an improved operation and a reduced number of shutdowns.

Weir Minerals Lewis Pumps – Stand 53

Formerly known as Chas. S. Lewis & Co., Inc., Weir Minerals Lewis Pumps manufactured its first sulfuric acid pump in 1914, beginning a specialisation that has continued to the present time. Today, the company is the world’s acknowledged leader in the design and manufacture of pumping equipment for sulfur chemical applications.

With material selections featuring the proprietary Lewmet® alloys to provide maximum corrosion resistance, the hydraulic and mechanical engineering concepts embodied in Lewis® Pumps sulfuric acid pumps assure the plant operator of outstanding performance and reliability in high temperature sulfuric acid and oleum. The company also offers a family of steam jacketed sulfur pumps to meet a diversity of applications for the production, transfer, and processing of sulfur from its points of production to the major points of use in sulfuric acid plants. Having first developed alloys for phosphoric acid service in 1957, today the company can select from a wide range of materials including both commercially available alloys as well as our proprietary Lewmet® alloys.

ISO 9001 registration underscores the company’s commitment to quality and superior customer service. With pumps and valves installed in more than 120 countries worldwide, Weir Minerals Lewis Pumps has the equipment to match your specific needs.

Worley Parsons – Stand 16

This front end study of each project seeks to maximise value and deal with the complexities relating to sulfur removal and disposal, including integration into customer facilities. This analysis also increases customers’ confidence that proposed solutions will provide the highest reliability and flexibility possible, while achieving greater processing capability, unit efficiency and maximum on stream time.

Zwick Armaturen Gmbh – Stand 64

Refining and gas processing companies have experienced many maintenance issues with butterfly valves in sulfur tail gas and acid gas service. Bearing failure is the highest root cause of these issues. This is because triple offset butterfly valves have metal bushing/bearings with very tight tolerances. If line media such as sulfur tail gas or acid gas penetrates these bearing cavities the free sulfur could cool down and harden.

Zwick’s Tri Con, metal seated, zero leakage butterfly valve has proven to deliver years of successful service in sulfur tail gas and acid gas. Zwick’s patented sealed bearing design is one feature that allows the Tri Con valve to deliver years of cycling without sticking or seizing due to sulfur changing phases and hardening in the bearing cavities. Over the past 12 years 10+ major oil and gas, and refining companies have replaced their existing sulfur tail gas and acid gas valves with the Zwick Tri Con and our sealed bearing design. In addition to the sealed bearing feature, Zwick also offers a welded on steam jacket. Valve size range is 3 ft – 96 ft.
