Part of my question is "do shielded ignition systems fully comply with Class 1, Grp D, DivII area classifications"? Reason for asking is that I have seen photos of gas engines with shielded ignitions operating at night where you can clearly see a "corona" or blue haze around the secondary...
In the cases that I am concerned with we are usually looking at a site that has limited space available to locate the compressor away from the potential source of explosive gas. Since most of these compressors require a concrete foundation and sometimes weigh in excess of 150,000# it is not...
I am a new member to this site and have a question that often comes up on oil and gas production sites. When a compressor is located on one of these sites it is often in what is classed as a Class 1, Group D, Div II location which calls for elimination of potential sparking sources. Is it...
Some operators classify a "common" oilfield production site as Class 1, Grp D, Div 2 because of the possibility of explosive gases being present during abnormal conditions. How can a gas engine driven gas compressor be located in such an area? (Same problem exists on offshore platforms) It is...
