Separator
A cylindrical or spherical vessel used to separate oil, gas and water from the total fluid stream produced by a well. Separators can be either horizontal or vertical. Separators can be classified into two-phase and three-phase separators (commonly called free-water knockout). The two-phase type deals only with oil and gas, while the three-phase type handles oil, water and gas. Additionally, separators can be categorized according to their operating pressure. Low-pressure units handle pressures of 10 to 180 psi [69 to 1241 kPa]. Medium-pressure separators operate from 230 to 700 psi [1586 to 4826 kPa]. High-pressure units handle pressures of 975 to 1500 psi [6722 to 10,342 kPa]. Gravity segregation is the main force that accomplishes the separation, which means the heaviest fluid settles to the bottom and the lightest fluid rises to the top. Additionally, inside the vessel, the degree of separation between gas and liquid will depend on the separator operating pressure, the residence time of the fluid mixture and the type of flow of the fluid. Turbulent flow allows more bubbles to escape than laminar flow.
Indirect Bath Heater
Function: Indirect Bath heater increase the flow ability of the crude & breaks the emulsion so that it can be separated in separator as oil, gas & water by increasing the temperature of the crude oil.
Indirect bath heater also helps the heat the crude oil in storage tanks by circulating the hot water to tank with coil.

Back Pressure Control valve
Back Pressure Valve can be used in any installation where upstream pressure is required to be kept at a preset range. It may also be used as: a pressure relief valve, a custody transfer dump valve to hold a certain back pressure, or as a separator back pressure valve on the gas or liquid side. Upstream pressure is applied to the bottom of the diaphragm through connecting tubing. Spring tension above the diaphragm opposes this pressure, and when the pressure exceeds the pressure setting on the spring, the plug is raised off the seat. By varying the spring tension, the pressure setting can be varied.
The typical application for these valves is to hold back pressure on separators, treaters, Lact units, etc.

Storage Tank
Petroleum industry requires storage tanks for holding crude oil prior to transportation to refineries. Storage tanks are available in many shapes: vertical and horizontal cylindrical; open top and closed top; flat bottom, cone bottom, slope bottom and dish bottom. S. Mark’s Large tanks tend to be vertical cylindrical, or to have rounded corners transition from vertical side wall to bottom profile, to easier withstand hydraulic hydrostatically induced pressure of contained liquid.
S. Mark manufactured tank capacity:
200 – 1000m3
Vaccum Furnace
S. Mark has designed surge tanks used to store produced liquids before disposal. The tank can also be used as an additional stage of separation and metering. The design of the surge tank also makes it possible to use as a second stage, two phase separator with the addition of gas and fluid metering. The unit is very effective where a longer retention time is required for good separation of gas and fluids. Another advantage of the surge tank is that the design allows the operator to keep back pressure on transfer pumps for production disposal.
S. Mark Surge Tank Sizes:

Diameter: 1842mm
-
Length: 6000mm
Gas Metering Skid
A gas metering skid is a part of a gas production plant that is pre-assembled on a steel structure, engaged to the measurement of gas products. It can be installed at the onshore or offshore location based on the requirement. Although several parameters are measured, the primary variable to be measured is the flow rate. Depending on the specific technology and user specifications, the measured flow rate can be a mass flow rate or a volumetric flow rate. The metering skid often used for further dealings, such as pressure-reduction by using control valves, filtration, and flow rate control by using different types of flow control valves.
Brine Filtration Unit
BRINCLEAN is S. Mark’s indigenously designed brine filtration unit. It meets industry requirements for good quality workover fluids.
BRINCLEAN is manufactured using high quality SS and strictly following ASME fabrication codes
BRINCLEAN produces brine with less than 4µ size
BRINCLEAN covers a wide range of filtering suspended particles: 40µ to 4µ sizes
BRINCLEAN has a 2 phase design that extends the life of the system
Knock Out Drums
Whenever a process requires that entrained droplets be removed from a vapor stream, a knockout drum should be integrated into the system. Condensation can occur when hot process gases cool considerably in the flare gas header and riser, and some gases also go to dew point at ambient temperatures and pressures and can therefore generate liquids. These droplets must be removed in order to avoid the phenomenon known as flaming rain, which occurs when liquid droplets are blown out the top of a flare stack along with ignited process gases. These vessels can be either horizontal or vertical.
