Calculations estimate process stream depositions
- Mobil Research and Development Corp., Paulsboro, NJ (United States)
A calculation method has been developed to estimate the conditions and extent of ammonium chloride and ammonium hydrosulfide depositions in refinery process streams containing ammonia, hydrogen chloride, and hydrogen sulfide impurities. Because salt deposition is a function of feedstock impurity, process temperature, and pressure, it is beneficial to be able to evaluate deposition propensity deductively for each susceptible stream. The evaluation should predict: where, or at what temperature, the salt starts to deposit; the kind of salt that deposits; and the approximate amount of the depositions. The paper describes the equations, thermodynamics, deposition tendency, extent of deposition, the algorithm, and a sample problem.
