Determination of Hydrogen Solubility in Petroleum Distillates at High Temperature and Pressure
Determination method of hydrogen solubility in petroleum distillates at high temperature and pressure was established,and the experiment process was optimized simultaneously.The method was then applied to determine the hydrogen solubility in toluene and heavy coking gas oil at different temperatures and pressures.Results show that the data of hydrogen solubility in toluene are just the same as the other researchers,and the deviation is less than 5%.At the same temperature,the hydrogen solubility both in toluene and heavy coking gas oil increases linearly with the pressure increasing.And at the same pressure,the hydrogen solubility both in toluene and heavy coking gas oil increases with the temperature increasing.This method is improved on the basis of the existing direct method,which increases the internal and external pressure balance process of the system,op-timizes the size of the experimental device,sampling and reading methods,and adds correction methods in places where meas-urement errors are easy to occur,making the measurement more accurate.
