Water Cooled Balanced Opposed Process Reciprocating Ethylene Compressor

About Us Greenfir offers a complete line of reciprocating compressors, many built to strict API 618 and ISO 13631 standards, and all backed by a global service network. These comprehensive capabilities allow us to manage a wide range of energy conversion projects for our clients. We can engineer, manufacture, procure, test, deliver, install, operate, and maintain your entire compressor system. Our extensive application experience with all major drive systems, including motors, engines, and turbines-allows us to precisely match the drive train to the compressor for maximum efficiency and reliability. We also provide all compressor accessories, piping, and packaging necessary to meet your total process and installation requirements. Our packaged units are ready for modular installation, with all compressor drive, lubrication, coolant, pulsation dampening, and control systems in place. This integrated approach simplifies ordering, delivery, and installation; reduces your coordination time and expense; lowers your engineering and construction costs; and provides singlesource accountability. Product Description The compressor adopts symmetrical and balanced structure, with two throws, two cylinders and two-stage compression. The cylinders are respectively located on each side of the frame. The gas inlet and outlet ports of the cylinders are arranged according to the upper inlet and lower outlet, with double function. The cylinder is equipped with an independent jacket, which is cooled by circulating water. The compressor will be located indoor with one layer arrangement. The distance piece adopts D-type long and short double compartments in article 6.12.1.5 of API 618, and the compartment is equipped with integral metal cover plate with gasket. The average piston speed is 3.564 m/s. The crankshaft speed is 594 r/min. The actual gas outlet temperature (@cylinder flanges) is ≤ 100 °C. The cylinder and packing case are with oil-free lubrication design and less oil lubrication operation. The compressor capacity control adopts the combined control of bypass and pneumatic unloading. Use the pressing-off suction valve for unloading. All unloading valves are air unloading, the load selection switch is located on the local instrument panel of the compressor unit, with 0, 50, 100% third gears, and the unloader is finger type. At the same time, "Stage-1 outlet reflux Stage-1 inlet" manual adjustment loops and "Stage-2 outlet reflux Stage-1 inlet"(Automatic regulating valve group) are equipped for capacity control and starting the compressor unit without load.
