Abstract
An existing system utilises addition of chemicals from a hopper 11 to a stream of drilling fluid introduced through a venturi 9. To more safely introduce hazardous liquid, powder or flake additives to the drilling fluid without additional power requirement, flexible non kink hose sections 4 connected by quick connect locking couplings 5 and controlled by full bore ball valves 3 and protected from backflow by flapper valve 2 are tapped into the existing venturi by means of a one inch threaded steel pipe 1. The hazardous chemical is thus sucked from its container 7. <IMAGE>
Description
SPECIFICATION
Hazardous chemical induction system
This invention comprises of an innovation fitted to an existing system in order to add hazardous chemicals safely.
Current chemical addition systems in the drilling industry comprise of a hopper//fitted onto a circulating system whereby on opening a valve 10 at the base of the hopper bulk chemicals or sack chemicals emptied into the hopper are drawn into the fluid stream passing through the circulating system. A venturi or vacum beneath the hopper to optimise the introduction of chemical additives to the fluid stream.
At present the introduction of hazardous flaked or liquid chemicals is by pouring the chemical from a drum into the hopper. This method is both time consuming and hazardous to the operators of the system.
The hazardous chemical induction system by tapping into the existing venturi or vacum will be capable of safely introducing hazardous chemicals in liquid, powder or flake form direct from their containers into the fluid stream without hazard to the operator.
A specific description of the invention with reference to the accompanying drawing now follows.
A threaded section of one inch bore steel pipe 1 is screwed into a threaded hole in the existing system directly above the venturi nozzle 9.
By means of one inch bore ball valves 3 and flexible non kink hose sections 4 fitted together with quick connect locking couplings 5 the chemical to be added 8 is sucked from its container 7 by means of a one inch bore steel pipe inductor 6 without any splashing or spillage.
The operator is protected against any backflow from the system, which could occur with pump failure. By the addition of a non return one inch flapper valve 2
CLAIMS
1. The hazardous chemical induction system comprises of a hose and valve innovation fitted to an existing system which makes use of an existing venturi to safely add chemicals to the fluid stream.
2. The hazardous chemical induction system requires no additional power source.
3. The hazardous chemical induction system can introduce one barrel 44galls of liquid chemical to the fluid stream in circa three minutes.
4. By means of altering the valve settings on the hazardous chemical induction system the rate of induction can be altered to suit the specific requirements of the operator.
5. The hazardous chemical induction system presents no spillage or splashing hazards to the operator.
6. The hazardous chemical induction system can be easily extended to suck fluids from storage tanks or container up to fifty feet from the hopper.
7. The hazardous chemical induction system and method is a new innovation to existing systems operated in the oil well drilling industry.
