To understand tank blanketing regulators, it’s important to first understand the process of tank blanketing. Tank blanketing, also known as “padding”, is the process of filling up the empty space of a liquid storage tank with a gas that’s not chemically reactive. In most cases, nitrogen is used for tank blanketing because it’s widely available and relatively inexpensive. Tank blanketing is used as a safety measure, as it removes the oxygen in a tank that could otherwise lead to combustion. Tank blanketing is also used to protect the liquid in the storage tank from oxidation, evaporation, and contamination. It can also prevent harmful vapors from escaping the tank and entering the atmosphere.

Tank blanketing is a common practice in many applications, including the chemical, oil & gas, food & beverage, and pharmaceutical & biopharma industries. Within these industries, blanketing is used for liquid storage tanks that contain chemicals, oil, food, beverages, pharmaceuticals, cleaning products, water, and much more.


How Does A Tank Blanketing Regulator Work?

Tank blanketing regulators, also known as padding regulators, are used to control the pressure inside a liquid storage tank. The regulator is placed on top of the storage tank and attached to the gas supply via the valve inlet. A sensing line will then be run from the tank to the regulator valve’s sensing port.

The blanketing regulator works by sensing decreases and increases in pressure. When a pressure decrease is sensed, the regulator valve will open and let more gas into the tank until the desired pressure is reached. When the regulator senses a pressure increase, the valve will close until the pressure in the tank returns to the set point.

Tank blanketing regulators are essential for optimizing liquid storage tanks because they account for changes in the system, including temperature changes, air or moisture entrance, and the pumping of liquids in and out of the tank.
