Valve design reduces costs and increases safety for US refineries
The goals were achieved by using alloys with superior corrosion resistance
In the 1980s and early 1990s, methyl tertiary butyl ether
(MTBE) was seen as an economical blending component that would
eventually replace processes like hydrofluoric (HF) acid
catalyzed alkylation (Fig. 1). However, MTBE was eventually
banned in the US due to public health concerns after the
chemical compound was detected in groundwater. As a result,
refineries shifted their focus from MTBE back to established
processes like HF alkylation to continue to produce
