One of our LNG Trains would be at half rates (12-13 mmscfh) for 7 days.
At the half rate condition there is usually a step increase in one of the methane exchanger DP. The step increase over 7 days will be significant.
To manage this it was recommended that the temperature of the LNG stream into the exchanger inlet, be maintained warmer than -109.75 degC. However at the present half rate condition the warmest that Operations dept. can achieve is -110.7degC.
To assist in achieving a warmer temperature we would like to know if the recycle valve on the 2 methane compressors H.S suction can be used over the 7 day period, without posing any risk(s) to the methane compressors?
