Abstract

The invention of a mobile package for primary oil processing is designed to prevent the burning of oil and to preserve the environment, taking into account the concerns of the Ministry of Petroleum to prevent the burning of oil in wells. This device includes various equipment required for processing oil at the wellhead, such as separators, desanders, descalers, surge tanks, oil transfer pumps, data collection systems, laboratories, chemical injection pumps, air supply units, nitrogen generator capsules, power generators, etc. It is deployed at the wellhead for various drilling, production, and maintenance operations. The impure and contaminated oil is purified and refined after passing through this device and is pumped to factories and operating stations through pipelines.

SYSTEM FOR PURIFYING CRUDE OILS

The invention relates to removing contaminants from oil using solid sorbents that are comprised primarily of carbon and preferably of coke particles. The coke particles have an affinity for contaminants in oil and are sized to be filtered from oil without plugging. Most contaminants have such a small size that they tend to plug up filters. As the contaminants agglomerate onto the solid sorbent, the resulting particles form a filter cake on conventional.

MICRO PROCESSING SYSTEM FOR MULTI-PHASE FLOW

A system for processing of multi-phase fluid, comprising a plurality of portable proximately arranged modules disposed over and spaced from a working pad where each module contains at least one separate processing element of a system for producing degassed and dehydrated crude oil and having a plurality of fluid carrying pipes interconnecting the processing elements in the said modules, including quick connect/disconnect joints in the pipe disposed between the said modules.

This system is an elaborated one and It works not only the crude oil but water and gas, on the other hand, our claimed system is a general perocessor for crude oil. The mentioned system produces dehydrated and degassed crude oil but our device processes the crud oil and adds substances to It.

A portable crude oil primary processing system with two trailers that performs the operation on any well and prevents the burning of crude oil with impurities. The system includes various equipment and sections required. The crude oil fluid enters the choke, and the Pressure and temperature of the fluid are received by sensors and sent to the data analysis center. The fluid then passes through a series of filters to remove solid particles, enters the separator, and is regulated through valves. The fluid goes into the surge tank to remove turbulence and is then pumped towards the destination with intended pressure. The controls and sensors are programmed by the PLC system, which also manages a chemical package to balance the pH of the fluid.

when the oil comes out is the issue of environmental pollution that it creates for the environment when the oil flows in the wells under repair, in the early days or temporarily. It has a lot of impurities sand particles and various acidic and mineral substances that make the extracted oil unusable in exploitation units and cannot be pumped, so in these cases, the output oil is burned to cause less damage to the environment. but the burning itself creates a kind of heavy pollution in the air, which causes respiratory and environmental damage. In this invention, it has been tried that the oil that is extracted in the initial moments is purified by the invented package and transferred to the transmission pipeline using a pump located on the package. This method solves both environmental problems and prevents the waste of tens of thousands of barrels of crude oil.

Solution of Problem

In this system, after settling in the right place, the crude oil fluid enters the choke, the crude oil pressure reaches a constant pressure, and its pressure and temperature are received by the sensors and sent to the analysis center. Crude oil enters a series of filters in the form of a three-phase fluid, and its solid particles are filtered, it enters the separator, where according to the nature of the three-phase fluid and the necessity of the operation, the circulation time of the fluid is checked and they are fully controllable by the sensors that are received on the water, gas, and oil outlets and by the control valves, then it enters the surge tank, where the turbulences are taken and the oil fluid is cool down. After that, the pumps pump the fluid with the desired layer towards the destination. In this system, the controls and sensors are programmed by the PLC system, and when the volume of the surge tank drops, the pumps are automatically turned off. There is also a package called a chemical package that is controlled through the PLC system and adds a series of substances to the fluid to balance the pH of the fluid.
