hi friend i am doing simulation for LNG Process. In my process i need to seperate Water and sand from the LNG..

Can Anyone suggest correct software for simulation............

Sorry your question leads more to questions than answers.

Separating water and sand from LNG... do you mean feed gas to an LNG facility.
Removal of sand and water from natural gas streams are standard gas processing steps and not specific to LNG.

If you are modelling the full LNG process, then specific modelling of sand is not required. You would assume that sand is removed in the inlet separators and is not modelled. Sand will not make it to the LNG.
If you do have a specific sand problem upstream, then you can use some standard calculations to model the carryover.

Likewise with water, the water specification for LNG is dry and therefore requires the use of molecular sieves for the removal.
There is no benefit to modelling the removal process as you are attempting to obtain a specific outlet conditions, so a simple component splitter (in hysys) suffices.
The Regen system can still be modelled for completness.

In summary, with respects to LNG simulation, water and sand can be assumed to be removed appropiately as specified in the design.
