    Injection Quill Design

    thanks sshep! for further info, the purpose of the water injection is to clean a downstream equipment on-line. particularly, this involves the washing of air-fin coolers that exhibit ammonium bisulfide fouling. this is the result of increasing the operating severity of a diesel hydrotreater...

    Injection Quill Design

    hello what will happen if i use a chemical injection quill for capacities that are significantly lower than its design, say 20% of rated capacity? the system shall involve injecting liquid water at around 3000 kPag in a hydrocarbon vapor stream of around 2800 kPag. distribution of the water is...
