In order to overcome the environmental and corrosion problems we have developed a process to concentrate sulfuric acid under vacuum. This enables to concentrate sulfuric acid up to 98wt% at less than 210°C which permits the use of steam as heating media and the use of glass-lined steel borosilicate glass 3.3 Tantalum and PTFE as material of construction.

Commercial concentrated sulfuric acid (66° Baume) is usually used for cooling water pH control. When fed neat it is nearly twice as dense as water and drops to the bottom of the cooling tower basin. This can damage basin concrete and cause poor pH control. For this reason the acid should be well mixed with water prior to entering the basin.

At the heart of every liquid sulphur melting and filtration plant a filter is installed. In most installations a liquid sulphur filter is used to remove impurities caused by both transportation and the reaction between Lime and Sulfuric Acid. The Sulphurnet Liquid Sulphur filters can be divided into three categories.
Crosby pressure relief valves have maintained leadership in overpressure protection for over 140 years. The direct spring-operated safety and pressure relief valves are among the worlds most widely used for oil and gas production and refining petrochemical and
In the sulfur burning conversion and dry absorption section of sulfur burning sulphuric acid system it is the preferred brand of valve for sulfur based sulfuric acid plant. It is considered as a butterfly valve with good sealing performance light operation secondary corrosion high temperature resistance convenient operation flexible operation safe and reliable use which has been widely used.
As the performance leader in the development of plastic valves and controls Plast-O-Matic provides a complete line of standard and custom designed solutions for difficult applications. Chem Resist Fluid Transfer is the exclusive UK agent for the complete range of Plast-O-Matic products.
Boilers installed in sulphur burning plants should have a bypass valve and a valve located at the gas outlet. The outlet valve is used during plant preheating to force hot combustion gases through the open bypass directly to the converter beds.
Sulfuric acid has also been found in lakes rivers and soil. The acid is extremely corrosive and harmful to the environment. The combustion of fuels containing sulfur (primarily oils and coals) results in pollutants occurring in the forms of SO2 (sulfur dioxide) and SO3 (sulfur trioxide) together referred to
