Advantages
The main advantages of using MAPRO® sliding vane rotary compressors for compressing biogas or natural gas are:

• Unchangeable and high efficiency MAPRO® rotary vane compressors are positive-displacement machines. That is, the compression takes place for progressive reduction, inside the machine body, during rotation, of the gas “volume” mechanically displaced from the suction to the discharge port. The discharge port is opened, on the internal cylindrical surface of the stator, at an height depending on the foreseen discharge pressure, so that only the power needed for the actual “compression” of the gas is used. It follows that the adiabatic compression efficiency is always high, and, in general, between the 70 and the 80% if referred to the compressor displacement.
• The tight internal clearances allow, as well, a high volumetric efficiency, basically unchangeable as blades wear is selfcompensating in time. The power needed for the compression is therefore, in general, lower than that required from other types of compressors, with consequent lower operating costs.

Simple and economic maintenance

• The small number of parts in motion simplifies the compressor disassembly and reassembly, so making these operations well less expensive than compared to other types of positive displacement machines. A specially provided control rod allows a quick evaluation, at fixed time intervals, of the blades wear, without disassembling, even partially, the machine body so as to enter the compression chamber. It is therefore possible to plan the blades replacement largely in advance, according to the working planning of the plant or to the maintenance needs of other equipments, so simplifying the plant operation and improving its efficiency and economy

Gas flow without pulsations

• The gas flow is continuous (no pulsation) both at the suction and at the discharge, and so there is no need to install storage tanks or gas dampers. MAPRO® rotary vane compressors are compact machines on which the light unbalance, due to the different radial position of the blades with respect to the axis of rotation, does not cause any significant vibration throughout the running operation. Therefore no special foundations are required. The rotary vane compressors are, in principle, less noisy than other types of compressors. Anyway, they can, when required, be supplied complete with acoustic enclosures.

Internal protection during compression of biogas

• The oil used for purely mechanical purposes, that is for the lubrication of bearings, blades, segments, mechanical seals, plays also two important roles in the biogas rotary vane compressors. The thin film of lubricating oil, constantly renewed, first protects the compressor's internal surfaces from attack of the acids in the biogas; and also tends to incorporate the impurities which are contained in the biogas in form of solid or liquid particles, with an effect of internal cleaning of the compression chamber. Therefore, the “oil renewed” lubrication makes MAPRO® rotary vane compressor, even if made of ordinary materials such as cast iron and carbon steel, particularly suitable for handling potentially corrosive gases which contain also impurities and moisture saturated. And these are, in general, the biogas peculiarities.

The most common fields of application

• Biogas recirculation into anaerobic digesters for sludge mixing;
• extraction of biogas from gasometer, landfill or other and delivery to storage systems or gas engine supply;
• extraction of natural gas from pipeline or gasometer, and delivery to storage systems or gas engine supply
