| Sumario: | The ammonia compression water cooling system of the Polinter low density polyethylene plant, C.A, has a capacity of 13,167,318 KJ / h (1040 TR) to satisfy the thermal load required by the process. This system is currently out of service; in such a way that the refrigerated water user equipment is deficient, generating losses of production and high consumption of raw materials. This research aims to propose an improvement of the cooling system of the PEBD Plant. For this, a simulation model was developed in steady state. Operating scenarios were proposed, modifying the flow of water into the system. A technical and economic evaluation was carried out, finding that the proposal with the highest benefit / cost ratio is the one where a flow control of water entering the system is established with the two units in parallel. It is recommended to design a logic for the flow control of water entering the cooling system, depending on the inlet temperature. |
