Abstract

Control system for transfer of liquid or liquefiable refinery fluid products to be transferred via tanker, wagon, vessel or pipeline. Fluid amount to be transferred can continuously be controlled by means of various control and calibration units positioned between fluid environments.

Description

SYSTEM FOR CONTROLLING THE TRANSFER OF LIQUID OR LIQUEFIABLE REFINERY PRODUCTS

Related technical field:

The invention is related to a flow control system that renders controlled transfer of liquid or liquefiable refinery fluid products to be transferred via tanker, wagon, vessel or pipeline. Fluid amount to be transferred can continuously be controlled by means of various control and calibration units positioned between fluid environments.

Existing condition of the technique

Determination of transferred amount is a very important step in the transfer of refinery petroleum and gas products from storage or preservation areas via tanker, vessel, pipeline to another storage or preservation area in refineries and filling terminals. The facilities where the transfer operation is performed are the facilities where usually big volumes are stored, big volumes are transferred and continuous operations are applied.

Transfer operation is generally product transfer operation from refinery or filling terminals storage environments to storage environment of buyer during selling of refinery petroleum and gas products . Determination of transferred product in net amount is one of the important steps of transfer process since the buyer make payment to the seller based on transferred product amount.

Large operation and transfer volumes and necessity of continuous operations require the subject transfer operation as quickly as possible. The necessity of completing the operation quickly makes it difficult to control and check such transferred volumes during the operation. When amounts and economic values of transferred products are considered, the economic values of encountered mistakes are also increased.

The reasons explained above make continuous calibration necessary for the flow control of refinery petroleum and gas products and the system used in refineries and filling stations.

In the current technique, direct transfer method can be given as an example for the methods used for the transfers between refinery petroleum and gas products storage environments (tank) . In direct transfer method, refinery product is being transferred from a storage environment (tank) with a known volume to another storage environment (tank) also with a known volume. Since the volume of the environment into which the transfer is done is known, the amount of transferred product can be calculated based on the tank volume.

Direct transfer method is not appropriate for making more than one operation on a storage environment concurrently. Therefore, transfer operation is being carried out firstly and then other operations are implemented respectively.

It is not possible to detect deviations to be appeared during the transfer operations since filling is being made based on volume filling without using a piece of control equipment in direct transfer method.

In the case that product transfer is made from one storage environment to multiple different storage environments of customers, the operations are done consecutively since they cannot be carried out simultaneously. Even if the deviations can be detected at the end of operation, it is not possible to determine which rate of deviation is realized during product transfer into which storage environment. Therefore, deviations that may occur after the transfer may lead to the emergence of disputes between buyers and sellers. Resolving these disputes can lead to the serious overtime losses.

The subject system is controlled by an operator. Therefore, mistakes are frequently encountered during tracking of system.

When apparatus and system parts used in the system require calibration, transfer operation is stopped and calibration is performed.

Since direct transfer method embodies above explained technical problems, it is possible to perform a transfer operation in high capacity, high efficiency and accuracy using mentioned system.

Another method used for the transfer of refinery petroleum and gas products between storage environments (tank) in usual use of technique is counter transfer system. In counter system, the amount of transferred product is measured with a counter positioned at least at one of the storage environments.

However this system is not suitable for product transfer from on storage environment to more than one storage environments. This situation requires the operations are made sequentially and therefore increase total operation time.

Similarly, using this method requires stopping of the operation to be able to calibrate sub elements of the system and restarting of the system after calibration.

It is possible to experience human based mistakes since the mentioned system is being executed under the control of operator.

For reasons described above, counter transfer system allows low capacity and low productivity operations. Purpose of the invention:

The purpose of the invention is to provide a transfer system which is able to work more efficient and in high capacity.

Another purpose of the invention is to provide a full automatic transfer system which can be controlled without operator.

Another purpose of the invention is to establish a transfer system which is able to carry out multiple different transfer operations simultaneously.

Another purpose of the invention is to be able to detect the deviations during the transfer operations immediately and allow required intervention to be made.

Another purpose of the invention is to establish a flow control system which is able to determine the deviations based on transfer operation and appropriate for intervening during operation.

To establish a flow control system capable of carrying out nonstop operations and prevent material losses originated from possible mistakes and increase operation capacity.

To establish a flow control system with a high customer satisfaction rate by mitigating the disputes that may emerge between buyer and seller by avoiding possible transfer and calculations mistakes.
