Study On Simulation Of Negative Pressure Crude Stabilizer Unit Of Gas Based On PSSP2.0Platform

PSSP is the process simulation system platform (Process System Simulation Platform), isset of petrochemicals, the refinery, the chemical installment simulation system developmentand the movement software platform. This article studies the content is uses the PSSP2.0system the application natural gas negative pressure original steady installment to carry on thesystem simulation to the oil industry, realizes to the installment operating parameter, thecontrol plan and the technical characteristic control, the newest control technology will applyin the negative pressure original steady controlled process, raises the natural gas negativepressure original steady efficiency and the quality.The negative pressure crude stabilizer unit of Gas ’s peculiar circumstance is described,which carries on the analog simulation with PSSP2.0to the substantial control system. Takethe negative pressure crude stabilizer unit as the example, explained the PSSP2.0controlsystem realized the process, the success has completed to the natural gas negative pressureoriginal steady system’s control. The development of the system consist of two sections,thefirst one is to establish process models,which are set up by selecting old modules andestablishing new unit modules.These models form an information flow graph.The other one isto develop the simulation DCS system.The work including configuration of Point,configuration of interface of system and configuration of communieation is aimed to form awhole simulation system.Three kinds of operation design of Crude Stabilization plant innormal operation: the detailed steps and process device and vehicle operation, normaloperation of the unit operation and equipment parking operation. The score of operator ismade by the scoring system. The negative pressure oil stabilizer unit operation trainingsystem base on DCS of PSSP2.0platform is verified effective.According to the test results from the field, the selection and allocation of the systemmeet the design requirements. Implementation of the negative pressure crude stabilizer unitbased on PSSP2.0is a reasonable and feasible schemes. The simulation already achieved thedesired effect. This platform can be applied to many similar control system of chemicalproduction device and makes certain actual engineering significance.
