Process for balancing the pressure of a flow stream consisting of a fluid containing a substance. Abrasive through the first process control valve, where the process includes: provision of a process control valve where the flow flow controls the process fluid with the abrasive having a pressure at one on the knot side and Second pressure on the second side of the first process control valve; The pump is positioned from the knot side of the first process control valve, where the knot consists of a floating piston inside the housing, one side of the floating piston is connected by fluid to a fluid without abrasive supplied. Maintained by a fluid path without first abrasive; The arrangement of the first secondary cylinder, combined with the piston, moves back and forth with one side connected by fluid to the fluid flow stream, controlling the end-side process from the second side of the first process control valve, the other. One of the pistons, moving back and forth, is connected by fluid with a fluid path that does not contain abrasives; Providing a first needle valve along the first non-abrasive fluid path between the pump and the secondary cylinder; And the opening of the needle valve to allow an abrasive-free fluid flow between the first secondary cylinder and the knot to balance the first pressure with the second pressure. 2. The process as outlined in the claim. Clause 1, which also includes: the arrangement of the second process control valve is connected by fluid to the end flow stream from the first process control valve and the first secondary cylinder, where the flow is at a pressure Two at the inlet side of the second process control valve and the third pressure on the outlet side of the second process control valve; The arrangement of the second secondary cylinder, combined with the piston, moves back and forth with one side connected by fluid to the fluid flow, controlling the end-side process from the second process control valve, the other side of the piston moving back and forth. Connect by fluid to a fluid path without a second abrasive; Providing a second needle valve along the second abrasive fluid path between the knot and the second secondary cylinder; Opening a second needle valve to allow an abrasive-free fluid flow between the second secondary cylinder and the pump to balance the second pressure with the third pressure, page 2 of the number 3, page 3. Specified in claim 2, it is also supplemented by providing the pump at two end-end from the second process control valve, where the second pump consists of a floating piston inside the housing, where one side of The floating piston is connected by fluid to a non-abrasive fluid, and where one side of the piston moves back and forth of the cylinder, the second secondary is connected by fluid to the second pump. 1, which is additionally incorporated by closing the needle valve after the first and second tonal balancing 5. The process, as outlined in Clause 4, also includes an additional compression stroke. Blocked by a floating piston on the flow after closing the needle valve 6. The installation process stated in Clause 1, is also supplemented by providing a reactor vessel arranged on the end end from the process control valve. The first one is. 7. The setting process is identified in this section. The right to Article 6, is also supplemented by providing a terminal product separator from the reactor 8. Process as outlined in Clause 7, where the second secondary cylinder is connected. 9. System for balancing the tonne of flow combining fluid with abrasive through one process control valve, where the system includes: Process control valve with flow Process control fluids with abrasive substances having a solidity on the first side and pressure on the second side; The side knot originating from the first process control valve, where the knot consists of a floating piston inside the housing, one side of the floating piston is connected by a fluid to a non-abrasive fluid; the first secondary cylinder is assembled. The piston moves back and forth with one side connected by fluid to the flow of fluid, controlling the end of the process from the second side of the process control valve, the other side of the piston moving back and forth, connecting the fluid to the path of the First abrasive-free flow; needle valve arranged along the first abrasive fluid path to control the flow of the first abrasive fluid between the first secondary cylinder and the pump; And where the needle valve is configured open to allow an abrasive-free fluid to flow between the first secondary cylinder and the pump to balance the first to the second pressure, page 3 of the number 3, page 1 0. The system, as outlined in claim 9, is additionally equipped with a reactor tank arranged on the end of a process control valve 1. 1. Claims based system clause 10, which is additionally assembled with a product separator arranged on the end of the reactor tank 1. 2. Claims based system Clause 11, The left side of the piston moves back and forth of the cylinder, the sub-inlet is connected by a fluid to the separator ------------
