CRUDE OIL AND OIL PRODUCTS TREATMENT METHOD
DESCRIPTION
This invention relates to the methods of treating crude oil and oil products prior to their transportation to a consumer.
There exist quite some number of methods of treatment of crude oil and oil products by means of introduction of different additives into the flow of crude oil and oil products transported by pipeline. The known technical solutions are aimed at solving the problems of pipeline crude oil and oil products transportation related to oil products' hydraulic resistance decrease, e.g. : RF Patent 2168108, F17D 1/16, published on 27.05.2001; crude oil/oil products rheological properties optimization, RF Patent 2111410, F17D 1/16, published on 20.05.1998; increase of efficiency of crude oil transportation by pipelines, RF PCT Request 94039950, F17D 1/16, published on 20.08.1996; crude oil demulsification, RF Patent 2009163, ClOG 33/04, published on 15.03.1994 etc.
However, the known methods do not ensure that certain crude oil and oil products performance properties are of the specification requested by the consumer what results in the impossibility to export such crude oil/oil products from the port of loading (where they are delivered by main pipelines or rail) due to their inconsistence with the buyers' requirements. Also, due to various reasons crude oil/oil products quality may deteriorate during their transportation by pipeline. Risk factors are: accidental blending with other oil products, dirty pipeline and tare walls, increase of water content in the result of intermediate storage in shore tanks or treatment of highly viscous oil products with open steam etc. Also, it often happens that oil products just manufactured by refineries do not already correspond to the
specifications adopted in the buyer's country or special requirements established by the buyer.
A method is known of introducing additives into the flow of fuel during filling of ship's fuel tanks. (V.A. Somov, P.P. Botkin "Fuel for transport diesel engines ", Leningrad, "Sudpromgiz", 1963, pp. 293-296). But, such method of additive introduction does not guarantee a homogeneous blending of the additive with the entire fuel volume. Therefore, a special mechanical mixing is required that is effected by way of a compulsory re-circulation of the fuel+additive blend on board a carrying vessel. A method is known of introducing additives into fuel during its loading at a terminal by doping additive into an empty, partially filled or a fully filled tank car (Reference Book, A.M.Danilov "Application of additives in motor car fuels", Moscow, "Khimiya", 2000, p. 192). But, this method does not ensure a long life of the results achieved through blending fuel with additive, and after some time the additive doped would settle down on the tank's bottom.
The aim of the claimed invention is to improve crude oil and oil products performance properties by means of increasing the efficiency of the method of treating crude oil and oil products with additives in ports.
The above aim is reached through the proposed method of treatment of crude oil/oil products, inclusive of injection of additives into crude oil/oil products, which is distinguished by the fact that the additives used to alter performance properties of crude oil/oil products are supplied into a shore-to-vessel crude oil/product loading pipeline during loading of a tanker vessel, and the additive content is set based on the required value of a particular performance property of the crude oil/oil product cargo being treated, and the estimated injection rate of such additive is in proportion to the product loading rate.
The proposed method allows to control the process of additivation proceeding from the requirement to obtain necessary performance properties of the treated crude oil/oil products and based on the tanker vessel loading rate. Since any alteration of the
injected additive content is directly related to the modification of the value of the particular performance property of the crude oil/oil product cargo being treated, the required value of the performance property being up-graded is set by the respective content of the additive being injected. Supply of additive at the injection rate regulated proportionally to the flow rate of crude oil/oil products via shore-to-vessel loading pipeline allows to maintain a constant "fed additive-to-product pumped" ratio thereby ensuring a homogeneous blending of additive with crude oil/oil products directly in the loading pipeline.
A final blending of additive with crude oil/oil products happens in the ship's tanks where a product's stream leaving the loading pipeline is characterized by the increased turbulence leading to the additional intensive mass-transfer between the additive and product treated which results in better blending and ensures a homogeneous distribution of additive throughout the entire volume of crude oil/oil products loaded into a tanker vessel. The proposed method allows to effectively mix additives with crude oil/oil products without using any additional mixers, and ensures the preservation of the stability of the result achieved.
The stability of such additivation effect has been confirmed by a practical use of the claimed method in the treatment of a shipment of gasoil with the depressor additive at the St. Petersburg Oil Terminal. The resultant modified gasoil performance properties were tested by the independent international inspection and certification company "SGS" accredited with the RF State Standards [Committee] and entitled to conduct cargo expertise and issue certificates. Comparative measurements of the cold filter plugging point of that gasoil have produced the following results : - untreated gasoil in shore tanks : - 9°C;
- treated gasoil during loading : - 22°C;
- treated gasoil after 7 days in the port of destination before discharge : — 22°C.
The above data shows that the additivation effect has been totaly preserved after transportation [of the treated product] in the tanker vessel's tanks. The test results are given in Tables 1, 2, 3.
The drawing shows the scheme of the method of treatment of crude oil/oil products in port.
Different types of additives can be used in this invention, viz. : depressor additives for gasoils and fuel oils, lubricity improvers for gasoils, H2S scavengers for fuel oils and crude oil, demulsifiers for all types of crude oils and oil products, cetane improvers, octane improvers, conductivity improvers and others. The examples are the TOTAL'S (France) : ethylene vinyl acetate based 7300-
Depressor Additive, fatty acids C2 - Cl 8 based PC30-Lubricity Improver and formaldehyde methanol and polymethyleneglycol aqueous solution based ASB 50- H2S Scavenger. The above additives in no way limit the use of other known additives by the proposed method. The method works as follows.
Example 1. Treatment of gasoil by Depressor Additive.
Gasoil of- 9°C Cold Filter Plugging Point (CFPP) is supplied from shore tanks 1 via pump station 2 by shore-to-vessel loading pipeline 3 to berth 4 and pumped into the tanks of tanker vessel 5 under loading. During loading of tanker vessel 5, additive is supplied from mobile injection unit 6 (a tank-container with additive or a special vehicle carrying additive tanks, a flow meter and necessary pumping equipment) and injected into pipeline 3 through injection points 7 and 8 specially provided on pipeline 3 running across the oil terminal. A uniform flow rate of additive is determined per the formula "Flow Rate (kg/hr) = Loading Rate (t/hr) * Additive Content (kg/t)" and set by the pump's feed stepless control dependant on the gasoil loading rate to be monitored by the flow meter's readings. The additive content is set based on the required value of CFPP in accordance with Table 4.
Example 2. Treatment of gasoil by Lubricity Improver.
During loading of tanker vessel 5, additive is supplied out of the additive tank loaded on board of tanker vessel 5 beforehand and injected directly into tanker vessel's 5 cargo manifold through measuring instruments' points provided upstream on tanker vessel's 5 cargo manifold. Additive is injected by a dosage pump driven by the compressed air system the air for which is supplied from tanker vessel's 5 main. The pump inlet is connected via flow meter with the discharge valve of the additive tank positioned on tanker vessel's 5 deck. The outlet nozzle of the dosage pump is connected to an injection point on tanker vessel's 5 cargo manifold. A uniform flow rate of additive is determined per the formula "Flow Rate (kg/hr) = Loading Rate (t/hr) * Additive Content (kg/t)" and set by the pump's feed stepless control dependant on the gasoil loading rate in tanker vessel's 5 cargo manifold to be monitored by the flow meter's readings. The additive content is set based on the required diameter of the Wear Scar (a parameter speaking of the gasoil's lubricity properties) in accordance with Table 5. Example 3. Treatment of fuel oil by H2S Scavenger.
Fuel oil of above 2 % H2S content is supplied from shore tanks 1 to pump station 2 by shore-to-vessel loading pipeline 3 to berth 4 and pumped into the tanks of tanker vessel 5 under loading. During loading of tanker vessel 5, additive is supplied from mobile injection unit 6 (a tank-container with additive or a special vehicle carrying additive tanks, a flow meter and necessary pumping equipment) and injected into pipeline 3 through injection points 7 and 8 specially provided on pipeline 3 running across the oil terminal. A uniform flow rate of additive is determined per the formula "Flow Rate (kg/hr) = Loading Rate (t/hr) * Additive Content (kg/t)" and set by the pump's feed stepless control dependant on the fuel oil loading rate to be monitored by the flow meter's readings. The additive content is set based on the required value of H2S content in the fuel oil with Table 4.
The use of the proposed invention ensures the preservation of the stability of the additivation result during at least 60 days. Table 7 shows comparative life-times of the stable additivation results achieved by the proposed invention method of treatment
of crude oil and oil products and other known methods of introduction of additives into tanker vessels' fuel tanks (V.A. Somov, P.P. Botkin "Fuel for transport diesel engines ", Leningrad, "Sudpromgiz", 1963, pp. 293-296).
The use of the proposed invention allows to perform tanker loading and crude oil/oil products treatment simultaneously and, as a result, obtain ready for shipment crude oil/oil products with the performance properties adjusted to the buyer's requirements. Due to the ease of application, this method can be utilized in any port involved in crude oil/oil product shipments.
