Delivery and implementation of compressor equipment

Petroform Sales L.P. has extremely high competence and experience, which allows us to offer the most accurate selection and the widest range of compressor equipment in exact accordance with the needs of the project.
Our company offers the most advanced technologies for the following types of compressor equipment:
The main advantage of twin screw compressors is their quiet operation. Compared to reciprocating compressors, twin screw compressors are more reliable, have more stable and volumetric air flow, and are also more energy efficient. Our company offers a range of solutions for equipping and improving twin screw compressors. We deliver as oil-injected and oil-free compressors.

Oil-injected сompressors use oil injection to cool and seal the gas charge. The oil is separated from the discharge stream, cooled, filtered and returned to the cycle. The oil traps non-polar particles from the incoming air, thereby effectively reducing the number of particles when the air flow interacts. To eliminate entrained compressor oil, we use a filtration system.

When using an oil-free compressor, the air is compressed by screws without the use of an oil seal. As a result, they usually have a lower maximum discharge pressure. However, achievable oil-free compressors that achieve pressures in excess of 10 bar and output volumes in excess of 55 cubic meters per minute.
Our company supplies customized centrifugal compressors with a wide range of variety of configurations. Compressor capacity from 50 to 8,000 m3 / min at pressures up to 45 MPa.
 In these compressors, the non-vortex air flow passes through a straight pipe and enters the centrifugal compressor.

The flow passing through the centrifugal impeller, begins to rotate faster, due to the increase of distance from the axis of rotation. Often, the flow leaving the centrifugal impeller moves at a speed close to the speed of sound. Then it passes through a duct with an increasing flow area in which the energy conversion takes place, the flow slows down.

If the flow must be reversed in order to enter the next part of the machine, such as another impeller or combustion chamber, flow losses can be reduced by directing the flow using fixed swivel vanes or separate tubular diffusers. According to Bernoulli's principle, a decrease in speed causes an increase in pressure.
A diaphragm compressor is a variant of the classic reciprocating compressor with backup and piston rings and rod seal. The compression of gas occurs by means of a flexible membrane, instead of an intake element. The back and forth moving membrane is driven by a rod and a crankshaft mechanism. Only the membrane and the compressor box come in touch with pumped gas. For this reason this construction is the best suited for pumping toxic and explosive gases.

The membrane has to be reliable enough to take the strain of pumped gas. It must also have adequate chemical properties and sufficient temperature resistance.
 Diaphragm compressors are ideal for compressing all gases without leaks or gas contamination. The advantages of gas processing are the ultra high purity without leaks, which is the difference between diaphragm compressors and reciprocating and screw compressors. Piston and screw machines can leak around the piston rings, contaminating the process gas with hydraulic oil.

This type of compressor is ideal for compressing toxic or potentially volatile gases such as hydrogen, as they are hermetically sealed to the outside, resulting in a very low leakage rate of around 10-4 mbar / s.
A reciprocating compressor or piston compressor is a positive-displacement compressor that uses pistons driven by a crankshaft to deliver gases at high pressure.
The intake gas enters the suction manifold, then flows into the compression cylinder where it gets compressed by a piston driven in a reciprocating motion via a crankshaft, and is then discharged. Applications include oil refineries, gas pipelines, chemical plants, natural gas processing plants, air conditioning, and refrigeration plants.

In the ionic liquid piston compressor many seals and bearings were removed in the design as the ionic liquid does not mix with the gas. Service life is about 10 times longer than a regular diaphragm compressor with reduced maintenance during use, energy costs are reduced by as much as 20%. The heat exchangers that are used in a normal piston compressor are removed as the heat is removed in the cylinder itself where it is generated.
Almost 100% of the energy going into the process is being used with little energy wasted as reject heat.
