Abstract
Oilfield processing plants need to continue upgrading to accommodate forecast production and achieve the specification of the standard product. Plants need to constantly review performance and operability especially when inlet streams vary in composition and rate over time and wells aging. Also global warming is nowadays one of the main and important issues. As the increase in the concentration of carbon dioxide and other greenhouse gases in the atmosphere as a result of the combustion of these gases causes such phenomena. The present work aims to retrofit an existing oilfield plant constructed in Egypt- Kalabsha central processing facility (KCPF) - to improve desalter performance and reduce the operating cost of crude oil shipping pumps. In addition to recovery of waste heat in drain water to disposal system that represents a value that can be used in heating brackish water which injected over desalter and in heating crude oil before shipping in the pipeline. Retrofit the studied oilfield plant is based on the implementation of two heat exchangers to recover the waste heat in the drain water. Also results showed that use waste heat in heating the brackish water of the desalter from 48.89 to 71.11 oC will increase the operating temperature of the desalter and therefore the settling rate required will decreased and separation of salts will improve. On the other hand, use waste heat in heating the crude oil before shipping from 37.78 to 71.11oC reduces the oil viscosity from 1.536 to 0.9735 c. St. Decreasing the crude oil viscosity will reduce the pressure DROP of the pipeline and therefore the energy required to pump the oil will be reduced. Moreover, it will reduce the drag injection dose required in the pipeline.
As well as studying the effect of flare gases recovery by using gas compressors on the economic and environmental performance of the plant under study. A commercial simulation program Aspen SYS Version 11 was used in simulating all proposed modifications. The Kalabsha Central Processing Facility (KCPF) plant designed to accommodates 30 million standard cubic feet per day (MMSCFD) from free water knock out drum and 1.6 MMSCFD of gases from heaters. 20 MMSCFD from gas is charged into the gas pipeline and 10 MMSCFD is sent to the flare along with the 1.6 MMSCFD from heaters to burn in the flare. It is proposed to install gas compressors to capture the gases from the free water knock out drum and heaters 11.6 MMSCFD before sending them to the flare. The presented retrofit design can be used as a guide in upgrading existing plants and plants under the design phase to increase plant reliability and safe operating costs as well as reduce gas flaring, in addition, environmental protection also adds more economic profits from burning gas the recovered besides increasing the life of the flare equipment. Therefore, oil and gas plants need to be constantly reviewed over time to maintain high performance and operability, especially while changing feed composition and rate to meet standard product specifications.
