1. A subsea facility for processing gas from a subsea gas production field, comprising:
a cooling module supplied with a gas/liquid mixture coming directly from at least one subsea gas field in order to cool the gas to a temperature allowing heavy hydrocarbons and water present in the mixture to be condensed; and
a gas/liquid separation module supplied with a gas/liquid mixture coming from the cooling module and which delivers processed gas to a gas export pipeline and liquid to a liquid export pipeline;
wherein the gas/liquid separation module comprises a gas/liquid separator and a coalescing filter separator which are connected in series, the gas/liquid separator having a gas outlet which is connected to an inlet of the coalescing filter separator and a liquid outlet which is connected to the liquid export pipeline, the coalescing filter separator having a gas outlet which is connected to the gas export pipeline and a liquid outlet which is connected to the liquid export pipeline.
