Optimum Utilization of Capacity Control Devices in Reciprocating Compressors
نویسنده
چکیده
capacity control consists of adjusting the quantity of gas supplied by the compressor to suit the fluctuating demands of the plant. In the modern processing plants, energy costs amount to about 65 per cent of the cwerall costs. Therefore, it is of paramount importance that the control system should be such that the compressor power is almost proportional to the quantity of gas delivered. For the optimal solution of the capacity control problem, certain issues must be taken into consideration at the planning stage of compressor plant so that maximum saving in pmver consumption is achieved with minimum initial cost and without impairing the safe running of the compressor plant. It is concluded that choice of capacity control device depends on many factors. Each compressor case has to be examined critically to arrive at optimum solution. INTROOUCTION Compressors, as part of process or refrigeration plants, long distance gas supply facilities, metallurgical plants etc. are required to have regulated ou-tput for diverse reasons such as: pressure variations must be compensated on the suction line; uniform pressure must be guaranteed for the irregular requirements of compressed mediums; constant cooling temperature must be provided for variable ambien-t temperatures; a certain processing procedure must be maintained. Capacity control consists of adjusting the quantity of gas supplied by tm cor.1pressor to suit the fluctuating demands of the plant.
