Abstract

A liquified gas dry cleaning system is provided which includes a cleaning vessel for containing a pressurized cleaning fluid and a storage tank for receiving and storing a cleaning fluid supply. The system also includes a cleaning fluid recovery still for separating contaminants from the cleaning fluid along with a filtration system for filtering contaminants from the cleaning fluid. A purge tank for receiving gaseous cleaning fluid which is in fluid communication with the cleaning vessel is also provided. The cleaning vessel, storage tank, purge tank, solvent recovery still and filtration system are arranged in a plurality of modules. The modules are in fluid communication with each other through a fluid line for carrying liquified cleaning fluid and a gas line for carrying gaseous cleaning fluid. The fluid line and gas line each include a respective junction for permitting separation of the modules. The fluid line junction and the gas line junction are disposed and configured such that the modules can be assembled in different configurations without any requiring any rerouting of the liquid and gas lines.
