Sulfur Foam and Commercial-Scale Field Application Equipment... 

Large-scale uses for this type of foamed-in-place insulation and application equipment are anticipated as the Canadian Arctic is developed. Successful results from these field tests and the prospects of commercial uses of the sulfur foam prompted Chevron Chemical Co. to proceed with the design, engineering, construction, and demonstration of a commercial-scale sulfur foam field application unit. 

On March 8, 1977 the Chevron Chemical Co. commercial field foaming equipment was demonstrated in Calgary to over 100 spectators representing local, provincial, and federal government, as well as local contractors and Canadian oil and gas companies (Figures 7, 8, and 9). This demonstration, jointly sponsored by Chevron and the Sulphur Development Institute of Canada (SUDIC), illustrated the practical application of sulfur foam in the field. 

The development of improved control instrumentation [e.g., of cathode location (placements), etc.] and many years of proven AP applications in the field have made AP the preferred method of controlling corrosion of uncoated steel equipment handling hot, concentrated sulfuric acid, stainless steel in even hotter exposures, and even steel in nitric acid. 

Chevron has demonstrated that it is commercially feasible to use sulfur composites as protective coatings and construction materials. This was done with large-scale field installations using special equipment and application procedures. Future efforts will focus on the commercial development of Chevron Sucoat products for these and other practical uses.
