20.500.12556/RUL-190010 Automation and supervision of an LPG extraction section experimental control analysis Avtomatizacija in nadzor procesa pridobivanja utekočinjenega naftnega plina Zaradi vse strožjih zahtev naftne in plinske industrije sta optimizacija procesov in zanesljivo delovanje naprav ključnega pomena. Zemeljski plin je treba pred distribucijo obdelati, da doseže predpisane kakovostne standarde, kar vključuje odstranjevanje vode in pridobivanje težjih ogljikovodikov, kot sta kondenzat in utekočinjeni naftni plin (LPG). V prispevku obravnavamo avtomatizacijo in nadzor naprave za pridobivanje LPG z destilacijo, pri kateri se propan in lažji butan ločujeta od težjih ogljikovodikov. Predstavljamo strategijo vodenja, razvito in izvedeno v porazdeljenem krmilnem sistemu YOKOGAWA CENTUM. Sistem zagotavlja natančno regulacijo temperature na vrhu kolone za odstranitev butana z usklajenim vodenjem povratnega toka in odvzema izopentana. Avtomatsko prilagajanje referenčnih vrednosti izboljšuje stabilnost procesa, zmanjšuje potrebo po posredovanju operaterja ter povečuje zanesljivost in učinkovitost naprave. Eksperimentalna analiza potrjuje učinkovitost predlaganega pristopa pri različnih obratovalnih pogojih. At the time when the oil and gas industry is facing increasingly stringent regulations, growing complexity in facilities and operations, and the pressing need to minimize shutdowns, optimization across all levelsfrom exploration to refining, from storage to distribution, and in the modernization of facilities for new projects has become critical for a continuous development and performance enhancement. The international market demands precise handling, with transportation and distribution carried out via pipeline networks. Natural gas must meet specific quality standards, including the calorific value, C5+ content, and moisture content. To achieve specification-compliant gas, raw gas extracted from wells undergoes a series of treatment processes aimed at removing water and recovering heavy hydrocarbon fractions, such as condensates and liquefied petroleum gas (LPG). LPG is a mixture of light hydrocarbons stored in the liquid state, and derived from petroleum refining and more generally from the treatment of natural gas.Our paper focuses on automation and supervisory control of an LPG extraction unit based on a distillation process designed to separate the propane and light butane fractions from heavier hydrocarbons. We propose an approach that involves the development and implementation of a control strategy using the YOKOGAWA CENTUM Distributed Control System (DCS). Our program ensures an accurate control of the debutanizer column top temperature through a coordinated management of the reflux control loop and the iso-pentane withdrawal loop. The implemented control system enables an automatic adjustment of the operating set points, improves the process stability, reduces the operator intervention, and enhances the overall reliability and efficiency of the LPG extraction process. Our experimental analysis demonstrates the effectiveness of the proposed automation strategy under different operating conditions.
