A compressor unit including a compressor is provided. The compressor unit includes a suction line and a discharge line, a control unit which controls the compressor and/or adjacent modules. A method to operate a compressor unit is also provided. To avoid any damage caused by non-gaseous fluid amount at least one detection device is disposed in the suction line to identify non-gaseous fluid amounts in the fluid to be compressed before entering the compressor. The detection device is connected to the control unit in a signal transmitting manner.

1. A compressor unit including a compressor, comprising: a suction line;a discharge line;a dissolving unit connected upstream from the compressor; anda control unit controlling the compressor,wherein a first detection device is disposed in the suction line to identify non-gaseous fluid amounts in a fluid to be compressed before entering the compressor,wherein the first detection device is connected to the control unit in a signal transmitting manner,wherein the dissolving unit dissolves non-gas amounts before entering the compressor using a jet stream of natural gas from a higher pressure tapped from the discharge line,wherein the dissolving is initiated when an amount of non-gaseous fluid detected exceeds a certain limit,wherein the compressor unit further comprises a separator disposed in the suction line which is separating non-gaseous fluid amounts from the fluid before the fluid enters the compressor,wherein the first detection device is provided upstream the separator, andwherein the compressor unit is disposed below sea-level on the ground near a well head of a natural as well. 2. The compressor unit as claimed in claim 1, wherein the control unit controls an operation speed of the compressor and is built in such a way that the operation speed is reduced when an amount of non-gas detected exceeds the certain limit. 3. The compressor unit as claimed in claim 1, wherein the compressor unit further comprises an electric motor which is enclosed together with the compressor in a gas-tight housing. 4. The compressor unit as claimed in claim 1, further comprising a second detection device which is provided downstream the separator. 5. The compressor unit as claimed in claim 4, wherein the second detection device is an optical sensor or an acoustic sensor. 6. A method to operate a compressor unit, comprising: providing a detection device to detect non-gaseous fluid amounts in a fluid to be compressed;connecting the detection device in a signal transmitting manner to a control unit;changing an operation of a compressor or adjacent modules by the control unit as a reaction to a detection of non-gaseous fluid amounts in the fluid;providing a dissolving unit upstream of the compressor;initiating by the control unit a dissolvation of amounts of non-gas before entering the compressor when the detection device detects an amount of non-gas exceeding a certain limit,wherein the compressor unit comprises the compressor, a suction line, a discharge line and the control unit, the control unit controls the operation of the compressor,wherein the compressor unit is disposed below sea-level on the ground near a well head of a natural gas well, andwherein the dissolvation is done using a jet stream of natural gas from a higher pressure tapped from the discharge line. 7. The method as claimed in claim 6, wherein the control unit lowers a speed of operation of the compressor when an amount of non-gaseous fluid in the suction line is detected exceeding the certain limit. 8. The method as claimed in claim 6, wherein a valve is provided in a line connecting the dissolving unit to the discharge line, andwherein the valve is controlled by the control unit. 9. The compressor unit as claimed in claim 1, wherein a first detection device is provided upstream of the separator and a second detection device is provided downstream of the separator.
