Abstract: A paraffin control unit with staged high voltage temperature controlled electric immersion heaters to maintain the paraffin component of the crude oil in the liquid phase. The paraffin control unit removes large volumes of naturally occurring fine sand from the incoming liquids while also removing the crude oil from the influent fluid stream, the natural gas from the influent fluid stream, salt water from the influent fluid stream, all while maintaining the temperature of the crude oil fraction above the cloud point of its paraffin constituent.

Abstract: A sand separator for capturing sand and rock debris from recovered natural gas fracturing fluid includes a cylindrical, high-pressure-rated vessel disposed vertically and immediately downstream of the gas wellhead. High pressure fracturing fluid enters the top of the separator into an inner flue extending coaxially downward to terminate a spaced distance above the bottom of the vessel. Transverse baffles spaced apart along the length of the flue extend through the flue to the inner walls of the vessel to keep the flue centered within the separator. As the fluid enters the separator, openings through the flue near the vessel inlet permit lighter weight and gaseous constituents to escape the fluid and bypass the flue, thereby reducing the velocity of the fluid remaining inside the flue. As the remaining fluid falls to the bottom of the vessel, it further slows as it reverses direction to rise between the flue and the vessel walls.

Abstract: A mechanical vessel may effectively and simultaneously displace a first undesired gas from within water with a second desired gas, and remove at least one alkaline species and oily matter from the water.

Each gasification chamber may have a mechanism that ingests and mixes a second gas into the water thereby physically displacing at least a portion of the first gas into a vapor space at the top of each gasification chamber from which it is subsequently removed. There is an absence of communication between the vapor spaces of adjacent chambers. An acid is added to remove the alkaline species, where the first gas is an optional by-product that is also removed.
