Why use CO2 compressor?

Carbon dioxide (CO2) captured from coal flue gas or syngas must be compressed (pressure between 1500 and 2200 psi) and then piped for use in geological storage, enhanced oil recovery or CO2 utilization. This is the process in a CO2 compressor.

1. What are the features of the CO2 compressor?

The features of the CO2 compressor are as the follows:

Hydraulic oil system: The hydraulic system ensures even diaphragm deflection, stops shock, cavitation and vibration, and creates quiet, smooth CO2 compressor operation. Pressure differentials and gradients are eliminated by a unique oil distribution technology. The system uses an automatic injection pump, a positive displacement high-pressure injection pump and a drain valve with a bypass valve for simple, effortless start-up.

Automatic unloading system: When started, the PDC machine's CO2 compressor restarts itself. Improper initiation can cause cavitation within the CO2 compressor and may cause damage to the cylinder head, head bolts, O-rings, diaphragm or process and hydraulic systems. With automatic unloading, there is no need for technicians to be there when the CO2 compressor restarts.

Corrosion resistant wetted materials: The contact part of each process is made of stainless steel and a rugged polymer resistant structure. This helps prevent premature diaphragm failure and minimizes costs when spare parts are needed, as well as reducing the frequency and downtime required for maintenance.

2. What are the benefits of using a CO2 compressor?

The expected benefits of using ecologically ideal carbon dioxide in the CO2 compressor include the following:

Safety: It is chemically inert (non-flammable, non-toxic) and does not produce toxic or irritating decomposition products in fire.

Reduce operating costs, save more than 10% of energy and easier operation and maintenance procedures. There is no need to restore, recycle, or recycle CO2. This also contributes to significant savings in the cost of individuals, training and service equipment.

Oil-free compression guarantees the mass of compressed CO2. Pollution poses a high risk to your production, so use oil-free technologies to protect your production process.

3. What are the examples of applications with oil-free CO2 compressors?

Applications in the beverage industry to reduce co2 concentration

CO2 compressors are used in breweries

CO2 compressors are used in the food and pharmaceutical industries as supercritical solvents in excess of 60bar. For example, remove caffeine from tea or coffee.

CO2 compressors are as a natural refrigerant with a heat pump. This application requires relatively high pressures in excess of 100bar.

CO2 compressors are for the storing of remaining electricity in the form of natural gas, produced by the synthesis of carbon dioxide and hydrogen. For example, carbon dioxide might come from a biogas upgrade plant, and hydrogen from an electrolytic system. Thus, methane produced by synthesis can be stored in natural gas grids.

The horizontal design of the CO2 compressor ensures reduced maintenance. We include reliable cylinders, reliable pistons and piston rods, quality valves and motors, high-quality stainless-steel components, and powerful drive systems.
