Drilling Fluids FILTER PRESS (model RCFH-71&RCFH-42) (HIGH-PRESSURE, HIGH TEMPERATURE) High Pressure-High Temperature (HPHT) Filter Presses are an efficient means of evaluating the filtration properties of drilling muds at high temperatures and pressures. The cells have a filtering area of 3.5 in2 and can be operated at pressures up to 900 psi with the compact, easily attached CO2 pressuring unit provided. Measurement of the filtration behavior and all-cake-building characteristics of an oil mud are fundamental to the treatment and control of a mud, as are the characteristics of the filtrate, such as the oil, water or emulsion content. Filtration characteristics of an oil mud are affected by the quantity, type and size of solid particles and emulsified water in the mud and by properties of the liquid phase. Interactions of these various components may be influenced by temperature and pressure. Therefore, filtration tests are often performed at both ambient temperature and at high-temperature conditions to provide data for comparison purposes. 1. Model RCFH-71 FILTER PRESS 500ML 500 ml HPHT Filter Press units can be pressurized to 1800 psig on the cell and 750 psig on the back pressure receiver. Maximum operating temperature is 500° F or operation above 400° the filter paper should b e F. F, backed with a glass fiber filter, or a stainless steel filter.
