Abstract

A method for generating and maintaining procedures for plant operation the method comprising:

• • a. Decomposing a plant into process units;
  • b. Decomposing each process unit into equipment modules (high-level objects);
  • c. Decomposing equipment modules into equipment units (low-level objects);
  • d. Defining operational states for equipment modules and equipment units;
  • e. Generating a procedures for changing operational states for equipment units;
  • f. Generating a procedures for changing operational states for equipment modules;
  • g. Encapsulating all the equipment units procedures and equipment modules procedures into process unit operations preferably in a computer database;
  • h. Providing feedback for presentation of the operational procedures and state changing operating procedures from the preferred database to an operator upon request;
  • i. Revising single equipment unit or equipment module operating procedure or state changing operating procedure upon request from the operator;
    wherein, the method allows the operator to receive a detailed description of an operating procedure for change of state of any process unit, equipment unit or equipment module in the plant from any state to any state.

Claims

1. A method for generating and maintaining procedures for plant operation the method comprising:

a. Decomposing a plant into process units;

b. Decomposing each process unit into equipment modules (high-level objects);

c. Decomposing equipment modules into equipment units (low-level objects);

d. Defining operational states for equipment modules and equipment units;

e. Generating a procedures for changing operational states for equipment units;

f. Generating a procedures for changing operational states for equipment modules;

g. Encapsulating all the equipment units procedures and equipment modules procedures into process unit operations preferably in a computer database;

h. Providing feedback for presentation of the operational procedures and state changing operating procedures from the preferred database to an operator upon request;

i. Revising single equipment unit or equipment module operating procedure or state changing operating procedure upon request from the operator;

wherein, the method allows the operator to receive a detailed description of an operating procedure for change of state of any process unit, equipment unit or equipment module in the plant from any state to any state.

2. The method of claim 1 wherein the same operating procedure for an equipment module can be reused for another equipment module.

3. The method of claim 1 wherein the same state changing operating procedure for an equipment unit can be reused for another equipment unit.

4. The method of claim 1 wherein one operating procedure may be used in several instances for operation of several equipment modules, while upon revising this procedure, it will be automatically revised for all the instances in all the processes, thus reducing the need to edit numerous instances of operational procedures.

5. The method of claim 1 wherein one state changing operating procedure may be used in several instances for operation of several equipment units, while upon revising this procedure, it will be automatically revised for all the instances in all the processes, thus reducing the need to edit numerous instances of operational procedures.

6. A method of generating and maintaining procedures for plant operation using a method of claim 4 or 5, wherein the procedure can be adapted to be used in another plant with a similar set of plant units without rewriting the whole operational procedure.

7. A method of generating and maintaining procedures for plant operation using a method of claim 4 or 5, wherein the procedure can be adapted to be used in another plant with a different set of plant units without rewriting the whole operational procedure.

8. A method for providing SAGD plant operation procedures, the method comprising:

a. Decomposing an SAGD plant into process units such as;

water de-oiling unit, evaporator unit, inlet cooling and separation unit etc.;

b. Decomposing each process unit for example evaporator unit into equipment modules such as;

feed module, distillate tank, evaporating tower, compressor, etc.;

c. Decomposing equipment modules for example compressor into equipment units such as first centrifugal pump, second centrifugal pump, suction drum, motor etc.;

d. Defining operational states for equipment modules and equipment units for example;

shut down, normal operation, recycling mode, heating mode, cooling mode, bypass etc.;

e. Generating a procedure for changing operational state for equipment units for example;

in order to change state of evaporator tower from normal to internal recycling operation, a specific set of steps has to be followed;

f. Generating a procedure for changing operational state for equipment modules for example;

in order to change centrifugal pump from full off to normal operation a specific set of steps has to be followed;

g. Encapsulating all the equipment unit procedures and equipment module procedures into process unit operations preferably in a computer database for example;

in order to operate an evaporator unit the following modules has to be initiated;

feed module, tower module, compressor module and distillate module while each module in turn has the sets of operation for each of its corresponding units incorporated as well;

h. Providing feedback for presentation of the operational procedures and state changing operating procedures from the preferred database to an operator upon request for example;

if the operator wishes to switch the evaporator from normal operation to internal recycle, the system will provide a detailed set of steps and the instructions of how to follow those steps;

i. Revising single equipment unit or equipment module operating procedure or state changing operating procedure upon request from the operator, if during the operation it was found that one of the instructions should be corrected, the correction can be made in the procedure of a specific equipment module or unit;

wherein, the method allows the operator to receive a detailed description of an operating procedure for change of state of any process unit, equipment unit or equipment module in the plant from any state to any state.

9. The method of claim 8 wherein the same operating procedure for an equipment module can be reused for another equipment module.

10. The method of claim 8 wherein the same state changing operating procedure for an equipment unit can be reused for another equipment unit.

11. The method of claim 8 wherein one operating procedure may be used in several instances for operation of several equipment modules, while upon revising this procedure, it will be automatically revised for all the instances in all the processes, thus reducing the need to edit numerous instances of operational procedures.

12. The method of claim 8 wherein one state changing operating procedure may be used in several instances for operation of several equipment units, while upon revising this procedure, it will be automatically revised for all the instances in all the processes, thus reducing the need to edit numerous instances of operational procedures.

13. A method of generating and maintaining procedures for plant operation using a method of claim 11 or 12, wherein the procedure can be adapted to be used in another plant with similar set of plant units without rewriting the whole operational procedure.

14. A method of generating and maintaining procedures for plant operation using a method of claim 11 or 12, wherein the procedure can be adapted to be used in another plant with different set of plant units without rewriting the whole operational procedure.
