Abstract
A liquid material reservoir which is used to collect liquid within a liquid or fluid transport system which is purged by means of introducing pressurized gas such as carbon dioxide into the system. As the pressurized gas is introduced into the system, liquid material which is purged from the system is forced into the reservoir, from which it may be reclaimed.
Claims5
A material reservoir for use within a liquid transport system, comprising:
- a. a reservoir tank located between a storage means and a distribution of processing means into which a liquid material is transported from said storage means;
- b. an inlet means into said reservoir tank connected to the storage tank which allows said liquid material to be transported into said reservoir tank from said storage means;
- c. an outlet means located on a lower surface of said reservoir tank from which said liquid material flows from said reservoir tank to said distribution means;
- d. a valve located on an upper surface of said tank which controls level of liquid within said tank by opening to allow gas which is present within said reservoir tank to exit said reservoir tank and allow said liquid material to enter said tank, and which closes to create a head pressure by means of said gas to prevent a greater volume of liquid from entering said tank;
- and
- e. a valve in a line located between said storage means and an upper part of said reservoir tank which directs said liquid material into said inlet means when closed, but which may be opened so as to allow pressurized gas to enter said reservoir tank above the level of said liquid material and force said liquid material out of said reservoir tank through said outlet means so as to purge the transport system.

- and
- e. a sensor means in a line located between said storage means and an upper part of said reservoir tank which closes said vlave when a liquid material is present within said line where said sensor is located, and which opens said valve when a gas is present in said line.
