1. A compressor installation comprising with a compressor device for compressing a gas, the compressor device including:
at least one liquid-injected compressor element into which a liquid is injected for lubrication, cooling, and sealing, and
an outlet pipe connected to an outlet of the at least one liquid-injected compressor element for receiving compressed gas coming from the liquid-injected compressor element,
a liquid separator mounted in the outlet pipe for separating liquid from the compressed gas coming from the at least one liquid-injected compressor element, which comprises a compressed gas inlet and a compressed gas outlet for the compressed gas coming from the at least one liquid-injected compressor element, and a liquid outlet for said liquid which has been separated by the liquid separator from the compressed gas coming from the at least one liquid-injected compressor element, and
a dryer connected to said outlet pipe and configured to use a desiccant to dry the compressed gas coming from the compressed gas outlet of the liquid separator, and
a heat exchanger for transferring heat from the compressor device to a regeneration gas for regenerating a desiccant,
wherein the dryer is provided with a drying section with an entry for the compressed gas coming from the liquid separator and an exit for the dried compressed gas that has been dried in the drying section, and a regeneration section with an entry and an exit for the regeneration gas,
wherein the regeneration gas is one of:
a portion of the dried compressed gas that has passed through the exit of the drying section and that is guided to the entry of the regeneration section via a regeneration pipe connected to the entry of the regeneration section, or
provided by an external source connected to the regeneration pipe,
wherein the heat exchanger has a secondary section connected to the liquid outlet of the liquid separator, and a primary section provided in the regeneration pipe for transferring heat from the compressor device to the regeneration gas,
wherein-the compressor installation is further provided with liquid injection regulation means to regulate an amount of liquid injected in the at least one liquid-injected compressor element.
