摘要： A hydrovac unit with a mud tank and water tank arranged symmetrically, so that the center of gravity does not substantially shift forwards or backwards during operation. The mud tank may be located inside the water tank. The mud tank may be supported and reinforced by external ribs, which may be fixed to the mud tank. The water tank may be formed by a rear face attached to the mud tank and a cylinder portion, the mud tank and rear face sliding into the cylinder portion for assembly and secured in place. The contents of the hydrovac unit may be dumped by tilting using a hoist. The tank assembly may be heated and insulated.

摘要： Thus there is disclosed a reciprocating top drive system that reciprocates a pump rod that goes to the bottom of the pump stinger to the bottom of the tank. The pump head is mounted at the end of the sting and is submerged in fluids in the tank. The pump head is carbide piston and sleeve with a very tight machined tolerance that allows the piston to pump up and down and glide in a film of the chemical that is slipping by the tolerance.

摘要： A flare stack with increased control of flow velocity of gases. The flare stack includes a pipe having a flare tip. The flare tip is provided with orifices and a sliding sleeve that opens and closes at least some of the orifices under control of an actuator. The actuator is pressure controlled. Nozzles extend from the orifices, parallel to each other. A central nozzle produces a stabilized flame. The nozzles which are controlled by the sliding sleeve are arranged in rings axially offset from each other along the pipe, so that the sleeve may open or close the nozzles in a ring as desired. The nozzles are symmetrically disposed, and terminate at the same plane, with the nozzles being disposed sufficiently close to each other that gas exiting any nozzle tends to draw in and merge with gas exiting from any adjacent nozzle.
摘要翻译：具有增加气体流速控制的火炬塔。火炬烟囱包括具有火炬尖端的管道。喇叭口具有孔口和滑动套筒，该致动器在致动器的控制下打开和关闭至少一些孔。执行器受压力控制。喷嘴从孔口延伸，彼此平行。中心喷嘴产生稳定的火焰。由滑动套管控制的喷嘴被布置在沿着管子彼此轴向偏移的环中，使得套筒可以根据需要打开或关闭环中的喷嘴。喷嘴对称地设置并终止在同一平面上，其中喷嘴彼此充分接近地布置，使得离开任何喷嘴的气体倾向于吸入并与从任何相邻喷嘴排出的气体合并。

摘要： A nozzle for a pilot light for a flare stack, the nozzle being formed of a housing defined by an encircling cylindrical wall, with radially extending openings formed circumferentially around the encircling wall, and is made of material resistant against breakdown in a sour gas environment at temperatures at least less than 1200.degree. C., preferably 98% by weight alumina ceramic. A cage holds the nozzle, which includes a base plate having a central aperture and first and second sides, a tube extending into the aperture from the first side of the base plate and fixed to the base plate, and plural retainers extending from the base plate and enclosing the nozzle. To form a pilot for a flare stack, a gas conduit is connected into an interior cavity of the nozzle. The cage is attached to a flame stack. Spaced electrodes form a spark gap adjacent one of the openings in the nozzle. A source of electrical power is connected to one of the first and second electrodes. One electrode extends in a ring, while the other extends in a plane. The cage is preferably grounded, with one electrode connected to the cage, and the second electrode is spaced from the cage and free to move in ambient wind conditions.

摘要： A thief hatch has a pressure relief valve and vacuum relief valve. Each valve may use a weighted pallet with a diaphragm that sits in operation on a seat surrounding a throat. Pressure from the interior of the tank, for the pressure relief valve, or pressure from atmosphere, for the vacuum relief valve, presses the diaphragm against the seat. If the pressure rises too much, the pallet and diaphragm will lift off the seat to relieve pressure.
