Stage and system for compressing cracked gas

A compression stage for the compression of cracked gas, the compression stage comprising:

• a liquid separating means for separating liquid components from gaseous components of a cracked gas;
• a compressor connected to the liquid separating means for compressing the gaseous components from the liquid separating means;
• a gas cooling means connected to the compressor for cooling a compressed gas from the compressor, wherein the gas cooling means are cooled by a first cooling fluid from a cooling fluid source;
• the stage further comprising gas precooling means connected to the liquid separating means for cooling the cracked gas before separation, the gas precooling means having an inlet for receiving the cracked gas, wherein the gas precooling means comprises a heat exchanging means and an absorption cooling means;
• wherein the heat exchanging means is cooled by a second cooling fluid from the absorption cooling means, wherein the absorption cooling means is arranged for generating the second cooling fluid using first cooling fluid from the cooling fluid source and heating fluid from a heating fluid source;
• wherein the first cooling fluid for the absorption cooling means is arranged to be supplied from a primary gas cooler of the gas cooling means of the stage, and
• wherein the first cooling fluid from the absorption cooling means is arranged to be supplied to a secondary gas cooler of the gas cooling means.
