Abstract: Production brines are used to scrub a horizontal stack receiving exhaust from an energy source, controlling, reducing, or both noxious chemicals. Mutual remediation of flows from petroleous production cool and scrub exhausts from flares burning waste hydrocarbons, heaters lowering viscosity of crude oil, engines driving oil pumps or natural gas compressors, and the like. Resulting evaporation of production brines results in distilled water, more concentrated brines to reduce hauling, or, optionally, dehydrated dry waste minerals from the brines. Year-round operation of brine evaporation ponds is facilitated, and may be another source of process pre-heating.

Abstract: Petroleous production is associated with effluents well known to foul lines, nozzles, and containers while consuming substantial energy to assist in both production and remediation. A heat exchanger and manifold system maximizes flows, minimizes changes in flow cross-section, and maximizes heat transfer area, while recycling both water and heat between processes. Dirty regions and clean regions result from scrubbing horizontal exhaust stacks and evaporation of production water in concert to remediate one another, while recycling a significant portion of the energy consumed by each. The heat exchanger relies on a manifold having many layered conduits, each connected to a single layer level of one or more cylindrical conduits in the exchanger. The cylinders of the exchanger themselves are arranged in multiple layers, each layer of a heat exchanger element being connected to a single layer of the manifold.

Abstract: A fluid evaporation system includes a housing bounding an airflow path. A misting system is positioned within the airflow path for spraying a wastewater into the airflow path. Water in the misted wastewater is evaporated, thereby concentrating minerals in the wastewater. A pretreatment system is positioned upstream from the fluid evaporator. The pretreatment system includes a gas induced separator. Separation of hydrocarbons and water are enhanced using a polymer and/or by lowering the pH of the wastewater.

Abstract: A fluid evaporation system includes a housing bounding a fluid reservoir and an air flow path that is disposed over top of the fluid reservoir. The housing has an inlet opening and a spaced apart outlet opening that both provide communication between the outside environment and the air flow path. A blower is positioned to draw the air into the air flow path and force the air through the outlet opening. A misting system positioned within the air flow path increases the water content of the air stream. A demister is positioned upstream from the outlet opening and downstream from the misting system.
