A separation system includes an elongated separator vessel having an inlet, a heating section which is located downstream of the inlet, an oil accumulation section which is located downstream of the heating section, and an oil outlet which is connected to the oil accumulation section. The heating section includes an immersed plate heater which is fluidly connected to a heating medium heater that is located externally of the separator vessel. In operation, a heating fluid which is heated in the heating medium heater is circulated through the immersed plate heater to heat the multiphase fluid.

Defoaming and/or foam suppression of a naturally derived water-soluble pigment is performed by a method including contacting an emulsified oil/fat containing an emulsifier and an oil/fat with the naturally derived water-soluble pigment or water-soluble pigment-containing substance. An emulsified oil/fat-containing preparation, a pigment preparation, and a pigment-containing composition for a defoaming and/or foam suppression method for a naturally derived water-soluble pigment or a water-soluble pigment-containing substance are also prepared.

A transportable separation apparatus for separating spent materials from oil and gas operations into a primarily solid component, a primarily liquid component and a primarily gas component. The transportable separation apparatus includes a first separation unit disposed on the transportable separation apparatus for receiving spent materials and beginning separation of the spent materials. The transportable separation apparatus connectable to a vehicle to be pulled on commercial roadways when the transportable separation apparatus is in a transportation configuration. The transportable separation apparatus further includes a second separation unit in fluid communication with the first separation unit for further separation of the spent materials. A method of using the transportable separation apparatus to separate spent materials.
