Sulfur removal, as currently practiced in the petroleum industry, can be achieved using three ways. The first option involves the use of thermal methods such as the various cracking techniques that concentrate the majority of the sulfur into the non-volatile products. Such processes are located in the conversion section of a refinery. The remainder of the sulfur may occur in the gases and as low-boiling organic sulfur compounds. The second option involves the use of chemical methods such as alkali treating as may be located in the product finishing section of a refinery. The third option is hydrodesulfurization that occurs in the conversion section of a refinery or in the finishing section of the refinery.

Sulfuric anodizing is commonly referred to as type II anodizing. Using an electrolytic solution of sulfuric acid at room temperature and a current density of 15 to 22 Amps per square foot forms it. The process can run for 30 to 60 minutes depending on the alloy used. This produces a generally clear coating, depending on sealing, and a minimum of 8µm thick. One third of the coating thickness can build up per surface and 2/3 will be penetration. Sulfuric anodize is the most widely used type of anodize and has many desirable benefits.

Sulphur Based Mortar contains plasticizer and inert fillers. It is extremely fluid and pours quite easily without lumps. It has a very good acids, alkalis and water resisting properties. It is mainly used as a joint for Brick lining, drainage channels and tank lining. It is extensively used in industries mainly jointing of acid proof brick and tiles in lining of pickling tanks, storage tanks, samps, drainage line, floor and sewerage line pipe joints. It is placed in a suitable clean, dry Kettle. It is melted over low heat by stirring with metal rod or ladle. It burns with a low blue flame.

Sulphuric and hydrochloric acid recovery system is used for the steel, wire and galvanizing industries. It deals with the ever-increasing environmental and legislative challenges facing companies working on metal finishing and cleaning processes. A crystallization process eliminates waste from operations using sulphuric acid. This process cools the spent pickling liquor and produces a saleable ferrous sulphate crystal. The advantage of this system includes the re-use of highly concentrated recovered acid in the pickling process and Stabilized and reduced time of pickling operations.
