Fox will be happy to run your specific application through our proprietary computer model and supply technical data promptly. There are no easy rules of thumb. Please complete our standard application Data Sheet - and be sure to indicate if turndown is required.
No. This works with steam - a condensible - but not with hydrocarbons. Request our bulletin on Vapor Recovery Ejectors for a more detailed explanation.
Usually not. Ejectors in most gas capture/vapor recovery applications have a high compression ratio and therefore are very sensitive to changes in motive gas flow rate. High compression ejectors can be considered to have no turndown. Multiple ejectors installed in parallel, with on/off valves, is an option to compress a widely varying range of gas flow rates.
No. A gathering manifold can collect leakage from multiple sources - and be connected to the suction of one ejector.
Although not as noisy as steam ejectors, vapor recovery ejectors can be loud. When noise abatement is required, we typically enclose the ejector within a sealed jacket that contains acoustical insulation.
Two types of ejectors fall in this category:
Fox has been supplying skid mounted ejector systems for decades. Tell us what you need.
Certainly not. Please request a copy of a 1954 article in 'Petroleum Refiner' describing a number of ejector installations.
